First steps :

1. Login as root (no password)
2. Run ‘passwd’ and type a new password in and repeat it.
4. Use SSH to login as root
5. Run ssh-keygen to setup Key pairs
6. Add the authorized_keys file
7. Create a user account (adduser) and disable the root password
8. apt-get update
7. apt-get install nano
8. nano /etc/hostname (e.g from ubuntu to main.servers.teachertime.com.au )
9. hostname -F /etc/hostname
10. Update Timezone using dpkg-reconfigure tzdata
11. bash (to see if the hostname and time zone environmental vars updated)
12. _installNewWebServer or apt-get install the list of apps after the alias’s…. Will be asked for MySQL root password
13. vnstat -u -i eth0 # Create the vnstat networking database
14. a2enmod deflate expires rewrite dav
15 dpkg-reconfigure exim4-config
16. Create the log file folders for apache ( e.g mkdir /var/log/apache2/filmsonthefly )
17. rsync -azvh –progress -e ssh <username>@<servername>.servers.filmsonthefly.com:/<username>/.cron /<username>/.cron # Copy the cron and maybe the scripts folder from the previous server
17. crontab -l && crontab -e # Install the MySQL database backup script and various other things
