20 Synchronize the System Clock

It is a good idea to synchronize the system clock with an NTP (network time protocol) server over the internet. Simply run

aptitude install ntp ntpdate

and your system time will always be in sync.

21 Install Some Perl Modules Needed By SpamAssassin (Comes With ISPConfig)

22 ISPConfig

The configuration of the server is now finished, and if you wish you can now install ISPConfig on it. Please check out the ISPConfig installation manual: http://www.ispconfig.org/manual_installation.htm

22.1 A Note On SuExec

If you want to run CGI scripts under suExec, you should specify /var/www as the home directory for websites created by ISPConfig as Ubuntu's suExec is compiled with /var/www as Doc_Root. Run

/usr/lib/apache2/suexec -V

and the output should look like this:

root@server1:~# /usr/lib/apache2/suexec -V
 -D AP_DOC_ROOT="/var/www"
 -D AP_GID_MIN=100
 -D AP_HTTPD_USER="www-data"
 -D AP_LOG_EXEC="/var/log/apache2/suexec.log"
 -D AP_SAFE_PATH="/usr/local/bin:/usr/bin:/bin"
 -D AP_UID_MIN=100
 -D AP_USERDIR_SUFFIX="public_html"
root@server1:~#

So if you want to use suExec with ISPconfig, don't change the default web root (which is /var/www) if you use expert mode during the ISPConfig installation (in standard mode you can't change the web root anyway so you'll be able to use suExec in any case).
