After the system is installed, the installer will prompt for software selection. Choose OpenSSH server, PostgreSQL database, and Samba file server for installation. After it finishes, it will prompt if you want to install the GRUB bootloader onto the master boot record. From my experience with [[Web Server Documentation|setting up the webserver]], choose "No" and on the next screen, install the bootloader to "/dev/sda /dev/sdb /dev/sdc /dev/sdd" and then if all goes well, the installation will finish. Take the CD out and then choose "Continue" and the system will reboot, at which point you should be able to boot into Ubuntu!
==User management==
===Adding Root Accounts to the box===
Assuming that you have root, you can create user accounts on the box and give them root too. This isn't necessary for regular users - they just need a Postgres user account (see below). To add users to the box, the process is:
First great the users group, checking the last group number (5xx is the next one):
cat /etc/group
/usr/sbin/groupadd -g 5xx username
Then add the user (it doesn't matter what you put for -p, it is going to be overwritten):
/usr/sbin/useradd -g username -G root -s /bin/bash -p xxxx -d /home/username -m username
where g is the primary group, G is other groups, p sets a password,
d declares a home directory and m makes the directory
Change the user's password:
passwd username
And add the user to the sudoers file
echo 'username ALL=(ALL) ALL' >> /etc/sudoers
====Deleting a user====
To delete a user:
/usr/sbin/userdel -r roger
where r removes the home directory
And to remove their group
/usr/sbin/groupdel username
And remove their entry from the sudoers file too if they had root.
