This page describes the configuration of the two new research computing machines: '''Father''' (Windows Server 2019) and '''Mother''' (Ubuntu Server 20. This configuration runs on our [[Research Computing Hardware]]04). Note that the configuration of the [[DIGITS DevBoxRDP Software Configuration]] is describes the software installed on its own pageFather.

The hardware description and complete build notes and configuration information for '''Bastard''', our blisteringly fast, multi-GPU, A.I. estimation platform, are on the [[DIGITS DevBox]] page. The hardware descriptions for Father and Mother are on the [[Research Computing Hardware]] page. See also: [[Recovering Astarte]] for notes on moving content from an old mediawiki installation to a new one. ==Both machines(Father and Mother)==

I tried various methods to get MathML to work and always failed. It looks like the community bet on Mathoid working out, but there's been no development on it for 5 months now, and it looks dead. The good news, if is that MathJax works just fine right out of the box:

#$wgSmjInlineMath = [ [ "$", "$" ], [ "\\(", "\\)" ] ]; Note: the last line lets you demark math with LaTeX-like syntax. I disabled it, as I use $ signs way too much in other contexts.

=====BibTeX=====

=====Upload Multiple Files===== Although the Upload multiple files extension installed fine, it is unmaintained and seems to have an issue. I removed its line from LocalSettings.php and deleted its extension directory. I then installed [https://www.mediawiki.org/wiki/Extension:SimpleBatchUpload Simple Batch Upload] using a tarball: in mediawiki/installs wget https://github.com/ProfessionalWiki/SimpleBatchUpload/archive/1.6.0.tar.gz tar -xzf 1.6.0.tar.gz -C /var/lib/mediawiki/extensions mv /var/lib/mediawiki/extensions/SimpleBatchUpload-1.6.0 /var/lib/mediawiki/extensions/SimpleBatchUpload In LocalSettings.php: wfLoadExtension( 'SimpleBatchUpload' ); $wgSimpleBatchUploadMaxFilesPerBatch = ['*' => 10,]; I had previously added Special:MultiUpload|Upload multiple files to http://www.edegan.com/wiki/MediaWiki:Sidebar. I replaced it with a link to [[Special:BatchUpload]]. =====Allow SVG images===== See https://www.mediawiki.org/wiki/Manual:Image_administration#SVG. Essentially, add svg to $wgFileExtensions, then install and designate an image converter. I went with rsvg: apt-get install librsvg2-bin vi LocalSettings.php $wgSVGConverter = 'rsvg'; =====Add HitCounters=====  wget https://extdist.wmflabs.org/dist/extensions/HitCounters-REL1_34-48dd6cb.tar.gz tar -xzf HitCounters-REL1_34-48dd6cb.tar.gz -C /var/lib/mediawiki/extensions vi ../LocalSettings.php wfLoadExtension( 'HitCounters' ); cd ../maintenance php update.php ====Change the Dbase====

I tried to 'rename' the dbase, creating a dedicated dbase user that has access to just the wiki's dbase, and resetting its password.

==Update Linux==Setting up for advanced template(s) import====

Get =====Robelbox===== Importing the Robelbox, or other, templates on mediawiki is tricky [https://stackoverflow.com/questions/678626/where-can-i-get-templates-for-mediawiki], at least the system first time that you do it. Once you've got everything up and running to datesupport templates (see above): apt-get update#Find the template on another mediawiki installation#Go to Special:Export on that installation and export the template (but not its revision history)#Import the template on the wiki using Special:Import, set the interwiki prefix to something that designates the source, like en for English Wikipedias.  apt-get upgradeI did this for the [https://ts.wikipedia.org/wiki/Template:Robelbox Robelbox template], which I got from https://en.wikiversity.org/wiki/Special:Export, however, it wasn't useable and I couldn't work out why. I ultimately deleted Robelbox, having found better boxes (see below) but I expect that my process for fixing the later issues would have sorted out the problems here too.

There were dependcy problem and other warnings during the processI got Template:Box-round from mediawiki.org: https://www.mediawiki.org/wiki/Template:Box-round. It finished withrequired installation of TemplateStyles, which in turn might need JsonConfig: In mediawiki/installs Errors were encountered while processingwget https: keyboard//extdist.wmflabs.org/dist/extensions/TemplateStyles-REL1_34-configurationc4d6f25.tar.gz xserver tar -xorgxzf TemplateStyles-core xserverREL1_34-xorgc4d6f25.tar.gz -input-wacomC /var/lib/mediawiki/extensions console wget https://extdist.wmflabs.org/dist/extensions/JsonConfig-setupREL1_34-linuxf877d87.tar.gz console tar -xzf JsonConfig-setup ubuntuREL1_34-minimal E: Subf877d87.tar.gz -process C /var/usrlib/binmediawiki/dpkg returned an error code extensions Add to LocalSettings.php wfLoadExtension(1'TemplateStyles' ); W: Operation was interrupted before it could finishwfLoadExtension( 'JsonConfig' );

I rebooted the serverNow [[Template:Box-round]] works fine but, like [[Template:Tl]], has an error message on its page about JsonConfig being missing. It came up ok and everything seemed fine (I'm doing this over terminal), but it is still claiming Note that there are updates. The issue might be related to a known Ubuntu bugTemplate: httpsT1 previously said [[Module://bugs.launchpadTNT]] was missing, so I got it from www.netmediawiki/ubuntuw/+source/console-setup/+bug/1770482Module:TNT). The solution(s) might be JsonConfig seems fine and shows in [[httpsSpecial://unix.stackexchangeVersion]].com/questions/202671/circular-dependency-in-ubuntu-release-upgrade]:

Look at the keyboard config fileI added: cat /etc/default/keyboard$wgJsonConfigEnableLuaSupport = true; # KEYBOARD CONFIGURATION FILEwhich gave: Lua error: bad argument # Consult the keyboard1 to "get" (5not a valid title) manual page. XKBMODEL="pc105" XKBLAYOUT="us" XKBVARIANT="" XKBOPTIONS=""

Remove and reinstall So instead, I put all the keyboard-configurationfollowing into LocalSettings.php to configure JsonConfig (see [https://www.mediawiki.org/wiki/Topic:Vdtgrltwf1e5bmdx]): // Safety:before extension.json, these values were initialized by JsonConfig.php apt-get remove keyboard-configurationif ( !isset( $wgJsonConfigModels ) ) { $wgJsonConfigModels = []; apt-get install keyboard-configuration } Note that this launches a screen where the only options are Afghani variants... so cancel it if ( !isset( $wgJsonConfigs ) ) { $wgJsonConfigs = []; } DEBIAN_FRONTEND $wgJsonConfigEnableLuaSupport =noninteractive apt-get install keyboard-configurationtrue; This ran and changed the keyboard layout file to the default // https://www.mediawiki.org/wiki/Extension:JsonConfig#Configuration # KEYBOARD CONFIGURATION FILE # Consult the keyboard(5) manual page $wgJsonConfigModels['Tabular.JsonConfig'] = 'JsonConfig\JCTabularContent'; XKBMODEL $wgJsonConfigs['Tabular.JsonConfig'] ="pc105"[ XKBLAYOUT 'namespace' ="us> 486,af" XKBVARIANT 'nsName' ="> 'Data'," XKBOPTIONS= // page name must end in "grp_led:scroll.tab", and contain at least one symbol vi 'pattern' => '/etc.\.tab$/default/keyboard', 'license' => 'CC0-1.0', I manually removed the af option and the commas 'isLocal' => false, essentially reverting the file (I like a scroll light). cd ]; /usr/share/X11/xkb/symbolsEnable Tabular data namespace on Commons - T148745 $wgJsonConfigInterwikiPrefix = 'commons'; ln -s us en$wgJsonConfigs['Tabular.JsonConfig']['remote'] = [ This was the other solution offered 'url' => 'https://commons.wikimedia. I was missing an en option, so that might be itorg/w/api.php' apt-get install keyboard-configuration Now it says that there is nothing to do, which is promising. ];

Try Then I copied over Module:Documentation/styles.css from mediawiki.org, commenting out the update again: apt-get update && apt-get upgrade Nothing happened and background image in line 168. And everything seems to work fine... shutdown -r now

On boot, I got the box reportsfollowing templates from mediawiki (via [https: Welcome to Ubuntu 18//www.04mediawiki.5 LTS (GNUorg/wiki/Linux 4.15.0-45-generic x86_64Special:Export mediawiki's Special:Export] to get dependencies): ...*Template:Colored box*Template:Navbox*Template:Help box 36 packages can be updated.*Template:Side box 30 updates are security updates.*Template:Note

The latest LTS version Now a new set of issues has emerged. These include JsonConfig problems (at the time of writingagain) is 20.04.1 , and template loops (see httpswhich I think are coming from Module://wikiTemplate translation), and missing dependencies (e.ubuntug, Template:Mbox and Module:Color contrast).com/Releases)Moreover, most of the templates render the if and other conditional logic statements, rather then executing them. So I could do an: apt-get dist-upgradeBut installed ParserFunctions (which I should really do a full backup have done before) and it solved everything first, so that isn't going to happen today.outstanding!

Add to LocalSettings.php wfLoadExtension( 'ParserFunctions' ); $wgPFEnableStringFunctions ===Overview===true;

There's a useful wordpress article on To do the front page, I copied the basics source of the approach, albeit [https://www.mediawiki.org/w/index.php?title=Template:Main_page&action=edit Template:Main page] from mediawiki to a hosted install perspectivepage (called Test) and created [Template: Main page/styles.css] using [https://www.wpbeginnermediawiki.comorg/wp-tutorialsw/how-to-restore-a-wordpress-site-with-just-database-backupindex.php?title=Template:Main_page/styles.css&action=edit mediawiki's code]. Then I rejigged the contents of the page!

The main install instructions areonly minor but non-obvious change, was that I used h2 headings inside each mainpage_box, rather than h3's. As a consequence, I needed to add the following to [[Template: httpsMain_page/styles.css]]://wordpress .org/support/article/howmainpage_box h2 { border-tobottom: none; } .mainpage_box h2 .header_icon { margin-install-wordpress/right: 5px; }

For theme customization beyond that done in the interface, or through a plugin (like Code Snippets Old instructions[https://wordpresswww.mediawiki.org/plugins/code-snippetswiki/Topic:R1j08xhjgrtkpj6q] suggest using [[Special:ExpandTemplate]]on mediawiki's wiki, wordpress says with the best approach is to create a child theme [httpsinput text <nowiki>{{:MediaWiki}}<//wwwnowiki>.wpbeginnerBut this isn't necessary as the template doesn't need expanding in its current (at the time of writing) incarnation.com/wp-themes/how-to-create-a-wordpress-child-theme-video/]Naturally, the page works well on MobileFrontend.

It seems that Twenty Fifteen has the most active installs, but all the Twenty seriesThe Mass edit page contains several examples, two of which are [https://wordpressshow "Undefined Control Sequence" errors.org/themes/author/wordpressdotorg/ default themes] made by wordpress are wildly popular. It might be worth These examples use backslashed square brackets (I can't even write them on the wiki using [https://wordpress.org/themes/twentytwenty/ Twenty Twenty], as it is the most recent and takes advantage of the block editor (Twenty Nineteen does too but gets mediocre reviewsnowiki tags), and I like the look which have issues because of [httpsExtension://wordpress.org/themes/twentyfourteen/ Twenty Fourteen]SimpleMathjax. Regardless, the extension seems to work just fine!

===PreGet the system up to date: apt-install===get update apt-get upgrade

Check PHP and MySQL. During the upgrade I need PHP >=7.3 and MySQL >=5.6 butchose: php --version*keep the local smb.conf PHP 7.2.24-0ubuntu0.18.04.6 *keep the local grub (cli) (built: May 26 2020 13:09:11) ( NTS ) mysql --new version mysql Ver 14in /tmp/grub.14 Distrib 5.7.31, for Linux (x86_64l1gqsHmubw) using EditLine wrapper

===Backing off===Remove and reinstall the keyboard-configuration: apt-get remove keyboard-configuration apt-get install keyboard-configuration First, mount Note that this launches a screen where the USB driveonly options are Afghani variants.

do-release-upgrade====Overview====  if no release found because you are too earlyRather than trying to update wordpress, add I think it best to install the latest version and use the old dbase. This will likely cause problems with images... but we made several suboptimal choices when we built the last version, including using a non-d to allow development (standard theme and customizing it will still install LTS if in a way thatprevented updates.  There's available) doa useful wordpress article on the basics of the approach, albeit from a hosted install perspective: https://www.wpbeginner.com/wp-tutorials/how-to-restore-a-wordpress-site-with-releasejust-upgrade database-dbackup/

===Address Choosing the upgrade issues===theme (https://wordpress.org/themes/ and https://wordpress.com/themes) is a major decision. This time I want a much more standard theme, that has better plugin and widget support, is responsive and gives a good mobile interface. I also don't want to pay but will have to trade that off against doing customization to make it look distinct.

The first casualty of It seems that Twenty Fifteen has the upgrade was most active installs, but all the networking configurationTwenty series, which are [https://wordpress.org/themes/author/wordpressdotorg/ default themes] made by wordpress are wildly popular.

RegardlessHopefully, an upgrade will fix that, it is possible to install 7.3 as well, as use that with apache2. add-apt-repository ppa:ondrej/php apt-get update apt-get install php7.3 apt-get install php7.3-cli php7.3-common php7.3-json php7.3-opcache php7.3-mysql php7.3-mbstring php7.3-zip php7.3-fpm php7.3-intl php7.3-simplexml Note we may need to fix some config again as it said: Creating config file /etc/php/7other issues.3/apache2/php.ini a2dismod php7.4 a2enmod php7.3 I ignored the following notices for now: NOTICE: To enable PHP 7.3 FPM in Apache2 do: NOTICE: a2enmod proxy_fcgi setenvif NOTICE: a2enconf php7.3-fpm systemctl restart apache2 update-alternatives --set php /usr/bin/php7.3 update-alternatives --set phar /usr/bin/phar7.3 update-alternatives --set phar.phar /usr/bin/phar.phar7.3 update-alternatives --set phpize /usr/bin/phpize7.3 update-alternatives --set php-config /usr/bin/php-config7.3 error: no alternatives for php-config (ignored for now)

I need to get Xwindows set Back up again. My best guess as to the cause of this issue is leftover Nvidia drivers from my attempts to install the GPUs on this box went bad in an earlier apt-get upgrade but I can't see them listeddatabases: dpkg -psql postgres /l | grep nvidia-driver There is a .Xauthority file, As researcher and an .ICEauthority file, in /homebulk/ed and both are owned by ed:edbackups/ mv lbo_Fc.dump lbo_Fc.dump.org pg_dump -Fc allpatentsprocessed > allpatentsprocessed_Fc.dump pg_dump -Fc accelerators > accelerators_Fc.dump pg_dump -Fc grants > grants_Fc.

After doing this Do the login would give a local desktop but neither the keyboard nor mouse worked.

But that just put me back where I was: with a login loop problem. So I tried switching to lightdmFinally: apt-get install lightdmumount /media/usb

And it worked even before a reboot. After a reboot, I had a different login screen but ====Do the actual desktop looked the same. The .Xauthority file is now 51 bytes big and I suddenly have a .xsession-errors, which contains a list of environment settings taking place... However, the machine then silently crashed that night and again the following morning. I couldn't find a specific cause in the logs but there did seem to be a number X and GNOME problems: journalctl -b -1 journalctl --since "1 hour ago"upgrade====

I ran an Run: apt update from the GUI, which may have helped. However, there was a warning about an issue with a screensaver the first time that I loaded lightdm, and the crashes seemed to happen sometime after a clean boot. So I uninstalled lightdm, and installed gdm (which failed as installed already) and rebooted but got no GUI. Then I uninstalled and reinstalled gdm and everything seems fine now. apt-get remove lightdmupgrade aptdist-get remove gdm3upgrade apt-get install gdm3autoremove

Incidentally do-release-upgrade if no release found because you are too early, I left a clock running in a terminal so that I could see when add the box went down -d to allow development (it will still install LTS if it crashed again. The clock code is:that's available) while [ 1 ] ; do echo -en "$(date +%T)\r" ; sleep 1; donerelease-upgrade -d

Then: do-release-upgrade -d I kept the old versions selected some choices (keep smd.conf, don't notify me of mediawiki and wordpress and moved them to /bulk/retired whatever, etc.) I let it replace postgres10 but it still gave me an "Obsolete Major Version" warning on postgres (using yyymmdd datesI said ok) mv /var/lib/mediawiki26082020 /bulk/retired/ mv /bulk/retired/mediawiki26082020 /bulk/retired/mediawiki20200826 mv /var/www/html/blog20200809 /bulk/retired/.

Regardless, it is possible to install 7.3 as well, as use that with apache2. add-apt-repository ppa:ondrej/php apt-get update apt-get install php7.3 apt-get install php7.htaccess 3-cli php7.3-common php7.3-json php7.3-opcache php7.3-mysql php7.3-mbstring php7.3-zip php7.3-fpm php7.3-intl php7.3-simplexml Note we may need to fix some config again as it said: Creating config file /etc/php/7.3/apache2/php.ini a2dismod php7.4 a2enmod php7.3 I ignored the following notices for now: NOTICE: To enable PHP 7.3 FPM in that folder to restrict access while we workApache2 do: NOTICE: a2enmod proxy_fcgi setenvif NOTICE:a2enconf php7.3-fpm systemctl restart apache2 vi blogupdate-alternatives --set php /usr/bin/php7.htaccess3 <RequireAny> update-alternatives --set phar /usr/bin/phar7.3 Require ip 192 update-alternatives --set phar.phar /usr/bin/phar.168phar7.23 update-alternatives --set phpize /usr/bin/phpize7.13 < update-alternatives --set php-config /usr/bin/RequireAny>php-config7.3 error: no alternatives for php-config (ignored for now)

Then set up the dbase by editing wp-config.php (it's easiest to modify the sample).=====PostGIS Issues===== I also checked postgres and everything seemed ok: su researcher psql vcdb4 cp blog/wp-config-sample.php blog/wp-config.php\l They are all there vi blog/wp-config\dx All my extensions report back.php Note Update: It seems something did go wrong. Just because the extensions report back doesn't mean they work! When I try to run queries that use PostGIS, I get some keys from: https SQL Error [58P01]: ERROR:could not access file "$libdir//api.wordpress.org/secretpostgis-key/12.1/salt/4": No such file or directory

Then I tried updating the backend works - go to http://wwwextension (I'm pretty sure that I'm running 2.edegan4.com/blog/wp-admin! However the health check shows a missing required module and two missing recommended modules. Fix that3): apt-get install php7ALTER EXTENSION postgis UPDATE TO "2.3-gd apt-get install php74.3-curl apt-get install php7.3-imagick apachectl restart";

Ironically, it then recommends But that didn't fix anything. I upgrade to PHP7checked the versions: select version(); PostgreSQL 10.14 (Ubuntu 10.14-0ubuntu0.18.04.1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 7.45.0-3ubuntu1~18.04) 7. but that would just give issues for mediawiki5.

To I need to get Xwindows set up HTTPS using Letagain. My best guess as to the cause of this issue is leftover Nvidia drivers from my attempts to install the GPUs on this box went bad in an earlier apt-get upgrade but I can's Encrypt, t see httpsthem listed://linuxize.com/post/secure-apache-with-let-s-encrypt-on-ubuntu dpkg -20l | grep nvidia-04/driver

vi /etc/apache2/conf-available/ssl-params.conf SSLProtocol all -SSLv3 -TLSv1 -TLSv1But that just put me back where I was: with a login loop problem.1 SSLCipherSuite ECDHE-ECDSA-AES128-GCM-SHA256So I tried switching to lightdm:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA- CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384 SSLHonorCipherOrder off SSLSessionTickets off SSLUseStapling On SSLStaplingCache "shmcb:logs/ssl_stapling(32768)" SSLOpenSSLConfCmd DHParameters "/etc/ssl/certs/dhparam.pem" Header always set Strict-Transport-Security "maxapt-age=63072000"get install lightdm

Enable some apache2 mods!And it worked even before a reboot. After a reboot, I had a different login screen but the actual desktop looked the same. The .Xauthority file is now 51 bytes big and I suddenly have a .xsession-errors, which contains a list of environment settings taking place... However, the machine then silently crashed that night and again the following morning. I couldn't find a specific cause in the logs but there did seem to be a number X and GNOME problems: a2enmod ssljournalctl -b -1 a2enmod headers a2enconf letsencrypt a2enconf ssljournalctl --params sudo a2enmod http2 systemctl reload apache2since "1 hour ago"

Run certbot!I ran an update from the GUI, which may have helped. However, there was a warning about an issue with a screensaver the first time that I loaded lightdm, and the crashes seemed to happen sometime after a clean boot. So I uninstalled lightdm, and installed gdm (which failed as installed already) and rebooted but got no GUI. Then I uninstalled and reinstalled gdm and everything seems fine now. certbot certonly apt-get remove lightdm apt-agree-tos --email ed@edegan.com --webroot -w /var/lib/letsencrypt/ -d edegan.com -d www.edegan.comget remove gdm3 Note that I needed an @ entry in my A record for edegan.com pointed to my IP address to apt-get the main challenge to succeed.install gdm3

Then set up Incidentally, I left a new apache2 config file (clock running in /etc/apache): mv sites-available/000-default.conf sites-available/000-default.conf.bak vi sites-available/edegana terminal so that I could see when the box went down if it crashed again.com.conf <VirtualHost *The clock code is:80> ServerName www.edegan.com ServerAdmin ed@edegan.com Redirect permanent / https://www.edegan.com/ </VirtualHost> <VirtualHost *:443> ServerName www.edegan.com Protocols h2 http/while [ 1.1 DocumentRoot /var/www/html ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined SSLEngine On SSLCertificateFile /etc/letsencrypt/live/edegan.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/edegan.com/privkey.pem # Other Apache Configuration Alias /wiki /var/www/html/mediawiki/index.php RewriteEngine On RewriteRule ^/*] ; do echo -en "$ (date +%{DOCUMENT_ROOT}/mediawiki/index.php [L] </VirtualHost> ln -s sites-available/edegan.com.conf sites-enabled/edegan.com.conf systemctl reload apache2T)\r" ; sleep 1; done

Finally, edit /etcI kept the old versions of mediawiki and wordpress and moved them to /cron.dbulk/certbot and append the following to the last line retired (after -renewusing yyymmdd dates): --renew-hook "systemctl reload apache2"mv /var/lib/mediawiki26082020 /bulk/retired/ certbot renew --dry-runmv /bulk/retired/mediawiki26082020 /bulk/retired/mediawiki20200826 Tests the renewal! mv /var/www/html/blog20200809 /bulk/retired/

===PDFEmbed IssueWordpress Redux===

The solution First, move the old folder to a new name, so that it is to edit mediawikithere for backup and then get the new install and unpack it. cd /extensionsbulk/PDFEmbedinstalls wget https:/PDFEmbed/wordpress.hooksorg/latest.phptar. For me it was line 103 that previously said:gz mv /var/www/html/blog /var/www/html/blog20200809 'src' => $filetar ->getFullUrl()xzf latest.'#page='tar.$page,gz -C /var/www/html/I changed this line to: cd /var/www/html/ 'src' => preg_replace("mv wordpress/^http:blog/i", "https chown -R www-data:", $filewww->getFullUrl()).'#page='.$page,data blog

This is mentioned Put an .htaccess file in a comment on a topic page, though presumably for an earlier version: httpsthat folder to restrict access while we work: vi blog//www.mediawikihtaccess <RequireAny> Require ip 192.168.2.org1 </wiki/Topic:Syxow0why4c0cvvm ==Install VSFTPD==RequireAny>

aptThen set up the dbase by editing wp-get install vsftpdconfig.php (it's easiest to modify the sample). cp blog/etc/vsftpdwp-config-sample.conf php blog/etc/vsftpdwp-config.conf_origphp vi blog/etc/vsftpdwp-config.confphp #Change the following write_enable=YES local_umask=022 ssl_enable=YES #Add the following (forces ssl) allow_anon_ssl=NO force_local_data_ssl=YES force_local_logins_ssl=YES ssl_tlsv1=YES ssl_sslv2=YES ssl_sslv3=YES Note get some keys from: https://api.wordpress.org/etcsecret-key/init1.d1/salt/vsftpd restart

Then add the backend works - go to http://www.edegan.com/blog/wp-admin! However the health check shows a user missing required module and set it uptwo missing recommended modules. Fix that: useradd apt-m blogget install php7.3-gd passwd blogapt-get install php7.3-curl usermod -a apt-G wwwget install php7.3-data blogimagick usermod -d /var/www/html/blog blogapachectl restart Ironically, it then recommends that I upgrade to PHP7.4... but that would just give issues for mediawiki. On the other hand, everything is now green and just 4 groups of recommendations remain. ====Config==== See [[Wordpress Blog Site (Tool)]] for the McNair Center's build.

Essentially you need to sign in to Google and set up an API in the console: https://console.developers.google.com/flows/enableapi?apiid=gmail&pli=1. However, this seemed to introduce a massive security hole unless you have G Suite, so I abandoned this approach. I had previously set up SMTP through Google for the wiki (See [[Research_Computing_Configuration#Confirm_Account]]). So, I used the same approach with Wordpress. In WP Mail SMTP Lite choose 'Other' (see the [https://www.wpbeginner.com/plugins/how-to-send-email-in-wordpress-using-the-gmail-smtp-server/ second method]). Then [https://wpmailsmtp.com/docs/how-to-secure-smtp-settings-by-using-constants/ edit wp-config.php to hardcode the values] (this ensures that the password, which is stored plain-text, is a little more secure.): define( 'WPMS_ON', true ); //You MUST set this if you want hardcoded values to work! define( 'WPMS_LICENSE_KEY', '' ); define( 'WPMS_MAIL_FROM', 'blog@edegan.com' ); define( 'WPMS_MAIL_FROM_FORCE', true ); define( 'WPMS_MAIL_FROM_NAME', 'The Blog at EdEgan.com' ); define( 'WPMS_MAIL_FROM_NAME_FORCE', true ); define( 'WPMS_MAILER', 'smtp' ); // Possible values: 'mail', 'gmail', 'mailgun', 'sendgrid', 'smtp'. define( 'WPMS_SET_RETURN_PATH', true ); define( 'WPMS_SMTP_HOST', 'ssl://smtp.gmail.com' ); define( 'WPMS_SMTP_PORT', 465 ); define( 'WPMS_SSL', 'ssl' ); // Possible values '', 'ssl', 'tls' - note TLS is not STARTTLS. define( 'WPMS_SMTP_AUTH', true ); define( 'WPMS_SMTP_USER', 'username@gmail.com' ); // SMTP authentication username, only used if WPMS_SMTP_AUTH is true. define( 'WPMS_SMTP_PASS', 'password generated by Google' ); define( 'WPMS_SMTP_AUTOTLS', true ); =====Author Comments===== The blog supports multiple authors and by default, Wordpress emails an author whenever one of their posts gets a comment. If you'd like to disable author comment emails but keep the moderator emails, there's a simple fix: '''Just go to wp-admin/options.php and set 'comments_notify' to 0.''' (See https://codex.wordpress.org/Option_Reference) More complicated methods involve writing your own plugin [https://wordpress.stackexchange.com/questions/150125/disabling-comment-notifications-for-post-author] to refine wp_new_comment_notify_postauthor[https://developer.wordpress.org/reference/functions/wp_new_comment_notify_postauthor/] or changing the hooks[https://developer.wordpress.org/reference/hooks/notify_post_author/] used in wp-includes/comment.php: $maybe_notify = apply_filters( 'notify_post_author', $maybe_notify, $comment_ID ); ====Social Media Integration==== Getting the social media icons on the menu and correctly linked up is very straight forward. Follow the [https://wordpress.org/support/article/twenty-fifteen/#add-social-icons guide for twenty-fifteen], which also works for 2020. Getting some share buttons was more problematic, particular as my planned social media usage is somewhat atypical (Twitter, LinkedIn, and Reddit, really in reverse order), and because I don't want to pay anything.  The free version of [https://revive.social/plugins/revive-old-post/ Revive Old Posts] lets you push content to Twitter and Facebook, but they want you pay to push to LinkedIn. The best free options seem to be:*[https://wordpress.org/plugins/add-to-any/ AddToAny Share Buttons] - Integrates with Google Analytics*[https://wordpress.org/plugins/simple-social-icons/ Simple Social Icons] - The simplest option*[https://wordpress.org/plugins/shared-counts/ Shared Counts] -- Counts hits (but using a 3rd party for data?)*[https://wordpress.org/plugins/wordpress-social-login/ WordPress Social Login] - if you want users to log in using their SM accounts (note: has a bimodal ratings distro)*[https://wordpress.org/plugins/jetpack/ JetPack] -- The plugin used by wordpress.com for this functionality.

It also uses an account on the wordpress.com cloud, which is a pain for those who are self-hosting. I went with AddToAny, as it had the most installations, is entirely open-source, and offers all the functionality I need. ====Avoiding JetPack==== I tried to add a profile picture, but by default, WordPress uses [https://en.gravatar.com/ Gravitar], which, surprise, surprise, links to your WordPress.com account... and to add a self-hosted site, you have to install JetPack. At this point, I felt harassed and doubly so because I didn't install JetPack and yet, some how, the profile picture correctly updated from the one I'd posted on Gravitar. What the hecK? ===SEO=== I used Site Kit plugin for wordpess, and for mediawiki I made a sitemap to submit to Google. See https://www.mediawiki.org/wiki/Manual:GenerateSitemap.php In mediawiki: mkdir sitemap php maintenance/generateSitemap.php --memory-limit=50M --fspath=/var/www/html/mediawiki/sitemap/ --identifier=edegancom --urlpath=/sitemap/ --server=https://www.edegan.com --compress=yes Then submit it to Google... I did this by making an alias in apache2.conf from sitemap to /var/www/html/mediawiki/sitemap/, then submitting https://www.edegan.com/sitemap/sitemap-index-edegancom.xml #in retrospect, I wish I'd used an identifier with 'wiki' in it but what the hey. And with that success behind you, install Google XML Sitemaps on Wordpress, chose some settings (on Settings -> XML-Sitemap), and then post the URL to Google: https://www.edegan.com/blog/sitemap.xml It seems Yoast already builds a sitemap, you just need to submit to it Google... (I uninstalled XML Sitemaps): https://www.edegan.com/blog/sitemap_index.xml ===HTTPS=== To set up HTTPS using Let's Encrypt, see https://linuxize.com/post/secure-apache-with-let-s-encrypt-on-ubuntu-20-04/ Install it and make some directories... apt update apt install certbot openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048 takes ~20 secs mkdir -p /var/lib/letsencrypt/.well-known chgrp www-data /var/lib/letsencrypt chmod g+s /var/lib/letsencrypt Set up the config files vi /etc/apache2/conf-available/letsencrypt.conf Alias /.well-known/acme-challenge/ "/var/lib/letsencrypt/.well-known/acme-challenge/" <Directory "/var/lib/letsencrypt/"> AllowOverride None Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec Require method GET POST OPTIONS </Directory>  vi /etc/apache2/conf-available/ssl-params.conf SSLProtocol all -SSLv3 -TLSv1 -TLSv1.1 SSLCipherSuite ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA- CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384 SSLHonorCipherOrder off SSLSessionTickets off SSLUseStapling On SSLStaplingCache "shmcb:logs/ssl_stapling(32768)" SSLOpenSSLConfCmd DHParameters "/etc/ssl/certs/dhparam.pem" Header always set Strict-Transport-Security "max-age=63072000" Enable some apache2 mods! a2enmod ssl a2enmod headers a2enconf letsencrypt a2enconf ssl-params sudo a2enmod http2 systemctl reload apache2 Run certbot! certbot certonly --agree-tos --email ed@edegan.com --webroot -w /var/lib/letsencrypt/ -d edegan.com -d www.edegan.com Note that I needed an @ entry in my A record for edegan.com pointed to my IP address to get the main challenge to succeed. Then set up a new apache2 config file (in /etc/apache): mv sites-available/000-default.conf sites-available/000-default.conf.bak vi sites-available/edegan.com.conf <VirtualHost *:80> ServerName www.edegan.com ServerAdmin ed@edegan.com Redirect permanent / https://www.edegan.com/ </VirtualHost> <VirtualHost *:443> ServerName www.edegan.com Protocols h2 http/1.1 DocumentRoot /var/www/html ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined SSLEngine On SSLCertificateFile /etc/letsencrypt/live/edegan.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/edegan.com/privkey.pem # Other Apache Configuration Alias /wiki /var/www/html/mediawiki/index.php RewriteEngine On RewriteRule ^/*$ %{DOCUMENT_ROOT}/mediawiki/index.php [L] </VirtualHost> ln -s sites-available/edegan.com.conf sites-enabled/edegan.com.conf systemctl reload apache2 Test it by going to https://www.ssllabs.com/ssltest/ Finally, edit /etc/cron.d/certbot and append the following to the last line (after -renew): --renew-hook "systemctl reload apache2" certbot renew --dry-run Tests the renewal! ====PDFEmbed Issue==== Enabling and requiring HTTPS causes an issue with PDFEmbed on mediawiki, where you get a blank frame. The PDF is still there, other images load fine, but the PDF frame won't render the PDF. The problem is actually that the PDF is served with HTTP and the rest of the page is served with HTTPS, and Chrome (and perhaps other browsers) don't render the insecure content as a consequence (see [https://www.mediawiki.org/wiki/Topic:Uhgnq0wbmzfurbj0] for a description of the symptoms, but not the solution.). The solution is to edit mediawiki/extensions/PDFEmbed/PDFEmbed.hooks.php. For me it was line 103 that previously said: 'src' => $file->getFullUrl().'#page='.$page,I changed this line to: 'src' => preg_replace("/^http:/i", "https:", $file->getFullUrl()).'#page='.$page, This is mentioned in a comment on a topic page, though presumably for an earlier version: https://www.mediawiki.org/wiki/Topic:Syxow0why4c0cvvm ====Another Issue==== Interestingly, I started getting a message from Google Chrome whenever I went to post wiki entries saying: "The information you’re about to submit is not secure". There's an option to "Proceed anyway" or "Go back".  This started after I had MultiTail running viewing apache's logs, but I couldn't see, beyond some kind of file lock examination, how it could work. I figured that it was a coincidence and something else might have happened.  My first thought was that my SSL certificate might have expired. However, the certificate looks valid and good, and the issue survived a reboot. By inspecting the webpages (in Chrome) and then reviewing the Console, I could see that it was caused by a mixed content problem: Mixed Content: The page at '<URL>' was loaded over HTTPS, but requested an insecure font '<URL>'. This request has been blocked; the content must be served over HTTPS. It seemed that I somehow have some font addresses hardcoded somewhere: Mixed Content: The page at ... was loaded over HTTPS, but requested an insecure font 'http://128.42.44.180/mediawiki/resources/assets/fonts/BonvenoCF-Light.otf'. This request has been blocked; the content must be served over HTTPS. The copy of Chrome on my desktop must somehow have been upgraded? Or something else changed to cause a change in behavior... The IP is from the old web server at the McNair Center, suggesting that when I migrated the McNair database into the new wiki, I migrated this issue. (Note that it doesn't appear to be something hardcoded into a .css file, or similar -- I can't find any trace on the filesystem and besides, this wiki was built from a fresh install.)  I found the URLs hardcoded in [[MediaWiki:Common.css]] (it must have been moved with the last big batch of pages and I somehow didn't notice!) but then couldn't edit it! It seems that following [https://www.mediawiki.org/wiki/MediaWiki_1.32/interface-admin Mediawiki 1.32], the rights to edit the interface were separated out, and users now need the editinterface right to change anything in the Mediawiki namespace. So, I went to [[Special:UserRights]] and gave myself permission. Then I edited the page, which changed the look-and-feel of my editor (I have no idea why), removed the consol messages, but left the problem (even after ctrl-shift-r cache flush on Chrome). ===Install VSFTPD=== With the security restrictions on wordpress, I now need an FTP server to get files for themes, plugins, etc. I like VSFTPD, as its simple, secure, and has a nice standalone config. Old documentation on an earlier install on the old [[Wordpress Blog Site (Tool)]] page. Instructions are here: https://linuxconfig.org/how-to-setup-ftp-server-on-ubuntu-20-04-focal-fossa-linux  apt-get install vsftpd cp /etc/vsftpd.conf /etc/vsftpd.conf_orig vi /etc/vsftpd.conf #Change the following write_enable=YES local_umask=022 ssl_enable=YES #Add the following (forces ssl) allow_anon_ssl=NO force_local_data_ssl=YES force_local_logins_ssl=YES ssl_tlsv1=YES ssl_sslv2=YES ssl_sslv3=YES /etc/init.d/vsftpd restart Then add a user and set it up: useradd -m blog passwd blog usermod -a -G www-data blog usermod -d /var/www/html/blog blog Test it: ftp 127.0.0.1 sftp 127.0.0.1

*http://praveen.kumar.in/2009/05/31/setting-up-ftps-using-vsftpd-for-wordpress-plugins-auto-upgrade/*https://askubuntu.com/questions/14371/how-to-setup-ftp-to-use-in-locally-hosted-wordpress To address some of the issues with the FTP server's file permissions in wordpress add to wp-config.php: define( 'WP_CONTENT_DIR', 'wp-content' ); define( 'FTP_BASE', '/var/www/html/blog/' ); If I chmod blog:blog /var/www/html/blog then everything seems to work find when I sftp but wordpress is unable to create a directory... I can't work out why this is happening. I expect it has to do with the need for another wordpress specific define() statement, but I'm spending too much time on it. So I'm going to use direct installation of plugins instead, and remove the FTP server as it is a point of vulnerability. apt-get remove vsftpd userdel blog ===Final Configuration Changes to Apache=== Lock down apache somewhat further (as now there are directories that shouldn't be listable, etc.) cd /etc/apache2 vi apache2.conf #Change the directory definitions. Notes that if -SomeOption is used then other options must have + or - in front of them: <Directory /var/www/html> Options -Indexes +FollowSymLinks AllowOverride All Require all granted </Directory> systemctl reload apache2 #To debug: systemctl status apache2.service ====Remove the debug setup==== In the wiki (LocalSettings.php), comment the debug lines (I can't see when I added them from the documentation, but if you want to see error messages during the config, you'd want them uncommented): #error_reporting( -1 ); #ini_set( 'display_errors',1 ); #$wgShowExceptionDetails = true; #$wgShowDBErrorBacktrace = true; #$wgShowSQLErrors = true; Check the permissions set using $wgGroupPermissions - see https://www.mediawiki.org/wiki/Manual:User_rights Run all the updates to the blog, etc., from the consol before locking it down. Then in wp-config.php, lock down the ability to install plugins, etc., by commenting: #define('FS_METHOD','direct'); Edit the .htaccess files in blog and mediawiki to allow access but with appropriate restrictions. Note that the rewrite rules for the blog are in its .htaccess file <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /blog/ RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /blog/index.php [L] </IfModule> To make the blog the default, edit /etc/apache/sites-available-edegan.com.conf, add an alias (don't alias to index.php as it will cause design issues, the rewrite rule for that is already in the .htaccess file!): Alias /blog /var/www/html/blog/ And change: RewriteRule ^/*$ %{DOCUMENT_ROOT}/mediawiki/index.php [L] To: RewriteRule ^/*$ %{DOCUMENT_ROOT}/blog/index.php [L] Then: systemctl reload apache2 Note: Don't change the DocumentRoot to the blog, as this will destroy the design of the wiki. The last rewrite rule will decide the default site! ===Changing the Wordpress url=== It seems likely that some Reddit bots are automatically blocking postings with the word blog in their URL. So I decided to move my Wordpress installation from /blog to /journal.  Note that I briefly tried 'article' (singular to save letters). I also considered 'paper', which is shorter but not quite right. Likewise study, etc. Also digest (which was a close second), review, bulletin, and pub (which was just too ambiguous). The problem with article is that although it looks good for article URLS, the landing URL is then www.edegan.com/article. A collection word is better. And journal appeals to the academic in me. To do this takes about 10 minutes (see https://wordpress.org/support/article/moving-wordpress/). You have to:#Make the change in Wordpress through wp-admin (you have to do this first!) - Set both the Wordpress Address (URL) and Site Address (URL) fields#Move the directory to the new name (at this point I could access www.edegan.com/article)#Fix aliases in apache and the default subdomain for landing (see below)#Fix the permalinks (update the .htaccess file)#Fix the links hardcoded in menus#(Create and) load up a new icon image (it is set under Appearance -> Customize -> Site Identity)#Run any updates etc.#Reconnect Google site kit#Rerun Yoast SEO optimizer To fix the main alias in apache: vi /etc/apache2/sites-available/edegan.com.conf Change: Alias /blog /var/www/html/blog/ RewriteRule ^/*$ %{DOCUMENT_ROOT}/blog/index.php [L] systemctl reload apache2 I also needed to:#Perform a backup (I really should have done this before moving the site but hey...)#Fix the images etc. (they initially fine... but I came to suspect that they were cached and an HTML inspected revealed the wrong URLs) Do the backup (with a user that has process privileges): cd /bulk/backups mysqldump --add-drop-table -h localhost -u user -p wordpress | gzip > wordpress-20210209.sql.gz or mysqldump --add-drop-table -h localhost -u user -p wordpress > wordpress-20210209.sql Then install and use Velvet Blues (see https://www.wpbeginner.com/plugins/how-to-update-urls-when-moving-your-wordpress-site/) and use it to change the URLs (use https:// as a page inspection shows that this is correct) ===Another Change to the Wordpress URL and some updates === As root get the mysql dbase details: mysql -p #hint: tsn select host, user from mysql.user; show databases; Read mail: less /var/mail/$(whoami) Look in wp-config.php for dbase, user, pword etc. cat /var/www/html/journal/wp-config.php Back up the dbase mysqldump --add-drop-table -h localhost -u root -p wordpress > wordpress-20220814.sql Change settings (on https://www.edegan.com/journal/wp-admin/options-general.php)* WordPress Address (URL)** https://www.edegan.com/articles* Site Address (URL)** https://www.edegan.com/articles Move the folder: cd /var/www/html/ mv journal articles Reload: https://www.edegan.com/articles/wp-admin/options-general.php? Fix the .htaccess file to do the permalinks cd articles vi .htaccess #change 2 instances of journal to articles Fix the links in the menu on https://www.edegan.com/articles/wp-admin/customize.php?* Change links in menus!
