The Perfect Server - Ubuntu 11.04 [ISPConfig 3] - Page 6

21 Install ISPConfig 3

To install ISPConfig 3 from the latest released version, do this:

cd /tmp
 wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz
 tar xfz ISPConfig-3-stable.tar.gz
 cd ispconfig3_install/install/

The next step is to run

php -q install.php

This will start the ISPConfig 3 installer. The installer will configure all services like Postfix, SASL, Courier, etc. for you. A manual setup as required for ISPConfig 2 (perfect setup guides) is not necessary.

root@server1:/tmp/ispconfig3_install/install# php -q install.php

The installer automatically configures all underlying services, so no manual configuration is needed.

Afterwards you can access ISPConfig 3 under http://server1.example.com:8080/ or http://192.168.0.100:8080/. Log in with the username admin and the password admin (you should change the default password after your first login):

The system is now ready to be used.

22 Additional Notes

22.1 OpenVZ

If the Ubuntu server that you've just set up in this tutorial is an OpenVZ container (virtual machine), you should do this on the host system (I'm assuming that the ID of the OpenVZ container is 101 - replace it with the correct VPSID on your system):

VPSID=101
 for CAP in CHOWN DAC_READ_SEARCH SETGID SETUID NET_BIND_SERVICE NET_ADMIN SYS_CHROOT SYS_NICE CHOWN DAC_READ_SEARCH SETGID SETUID NET_BIND_SERVICE NET_ADMIN SYS_CHROOT SYS_NICE
 do
   vzctl set $VPSID --capability ${CAP}:on --save
 done

22.2 SquirrelMail

Lots of people have reported problems (such as getting 404 Not Found errors) using the SquirrelMail webmail package in their web sites created through ISPConfig 3. This guide explains how to configure SquirrelMail on an Ubuntu 11.04 server so that you can use it from within your web sites (created through ISPConfig).

SquirrelMail's Apache configuration is in the file /etc/squirrelmail/apache.conf, but this file isn't loaded by Apache because it is not in the /etc/apache2/conf.d/ directory. Therefore we create a symlink called squirrelmail.conf in the /etc/apache2/conf.d/ directory that points to /etc/squirrelmail/apache.conf and reload Apache afterwards:

cd /etc/apache2/conf.d/
 ln -s ../../squirrelmail/apache.conf squirrelmail.conf
 /etc/init.d/apache2 reload

Now open /etc/apache2/conf.d/squirrelmail.conf...

vi /etc/apache2/conf.d/squirrelmail.conf

... and add the following lines to the <Directory /usr/share/squirrelmail></Directory> container that make sure that mod_php is used for accessing SquirrelMail, regardless of what PHP mode you select for your website in ISPConfig:

[...]
<Directory /usr/share/squirrelmail>
  Options FollowSymLinks
  <IfModule mod_php5.c>
    AddType application/x-httpd-php .php
    php_flag magic_quotes_gpc Off
    php_flag track_vars On
    php_admin_flag allow_url_fopen Off
    php_value include_path .
    php_admin_value upload_tmp_dir /var/lib/squirrelmail/tmp
    php_admin_value open_basedir /usr/share/squirrelmail:/etc/squirrelmail:/var/lib/squirrelmail:/etc/hostname:/etc/mailname:/var/spool/squirrelmail
    php_flag register_globals off
  </IfModule>
  <IfModule mod_dir.c>
    DirectoryIndex index.php
  </IfModule>
  # access to configtest is limited by default to prevent information leak
  <Files configtest.php>
    order deny,allow
    deny from all
    allow from 127.0.0.1
  </Files>
</Directory>
[...]

Create the directory /var/lib/squirrelmail/tmp...

mkdir /var/lib/squirrelmail/tmp

... and make it owned by the user www-data:

chown www-data /var/lib/squirrelmail/tmp

Reload Apache again:

/etc/init.d/apache2 reload

That's it already - /etc/apache2/conf.d/squirrelmail.conf defines an alias called /squirrelmail that points to SquirrelMail's installation directory /usr/share/squirrelmail.

You can now access SquirrelMail from your web site as follows:

http://www.example.com/squirrelmail

You can also access it from the ISPConfig control panel vhost as follows (this doesn't need any configuration in ISPConfig):

http://server1.example.com:8080/squirrelmail

If you'd like to use the alias /webmail instead of /squirrelmail, simply open /etc/apache2/conf.d/squirrelmail.conf...

vi /etc/apache2/conf.d/squirrelmail.conf

... and add the line Alias /webmail /usr/share/squirrelmail:

Alias /squirrelmail /usr/share/squirrelmail
Alias /webmail /usr/share/squirrelmail
[...]

Then reload Apache:

/etc/init.d/apache2 reload

Now you can access Squirrelmail as follows:

http://www.example.com/webmail
 http://server1.example.com:8080/webmail

If you'd like to define a vhost like webmail.example.com where your users can access SquirrelMail, you'd have to add the following vhost configuration to /etc/apache2/conf.d/squirrelmail.conf:

vi /etc/apache2/conf.d/squirrelmail.conf

[...]
<VirtualHost 1.2.3.4:80>
  DocumentRoot /usr/share/squirrelmail
  ServerName webmail.example.com
</VirtualHost>

Make sure you replace 1.2.3.4 with the correct IP address of your server. Of course, there must be a DNS record for webmail.example.com that points to the IP address that you use in the vhost configuration. Also make sure that the vhost webmail.example.com does not exist in ISPConfig (otherwise both vhosts will interfere with each other!).

Now reload Apache...

/etc/init.d/apache2 reload

... and you can access SquirrelMail under http://webmail.example.com!
