24 Install SquirrelMail

To install the SquirrelMail webmail client, run...

yum install squirrelmail

Then configure SquirrelMail:

/usr/share/squirrelmail/config/conf.pl

We must tell SquirrelMail that we are using Courier-IMAP/-POP3:

One last thing we need to do is modify the file /etc/squirrelmail/config_local.php and comment out the $default_folder_prefix variable - if you don't do this, you will see the following error message in SquirrelMail after you've logged in: Query: CREATE "Sent" Reason Given: Invalid mailbox name.

vi /etc/squirrelmail/config_local.php

<?php
/**
 * Local config overrides.
 *
 * You can override the config.php settings here.
 * Don't do it unless you know what you're doing.
 * Use standard PHP syntax, see config.php for examples.

 */
//$default_folder_prefix                = '';
?>

You can now find SquirrelMail in the /usr/share/squirrelmail/ directory.

After you have installed ISPConfig 3, you can access SquirrelMail as follows:

The ISPConfig apps vhost on port 8081 for nginx comes with a SquirrelMail configuration, so you can use http://server1.example.com:8081/squirrelmail or http://server1.example.com:8081/webmail to access SquirrelMail.

If you want to use a /webmail or /squirrelmail alias that you can use from your web sites, this is a bit more complicated than for Apache because nginx does not have global aliases (i.e., aliases that can be defined for all vhosts). Therefore you have to define these aliases for each vhost from which you want to access SquirrelMail.

To do this, paste the following into the nginx Directives field on the Options tab of the web site in ISPConfig:

        location /squirrelmail {
               root /usr/share/;
               index index.php index.html index.htm;
               location ~ ^/squirrelmail/(.+\.php)$ {
                       try_files $uri =404;
                       root /usr/share/;
                       fastcgi_pass 127.0.0.1:9000;
                       fastcgi_index index.php;
                       fastcgi_param SCRIPT_FILENAME $request_filename;
                       include /etc/nginx/fastcgi_params;
                       fastcgi_param PATH_INFO $fastcgi_script_name;
                       fastcgi_buffer_size 128k;
                       fastcgi_buffers 256 4k;
                       fastcgi_busy_buffers_size 256k;
                       fastcgi_temp_file_write_size 256k;
                       fastcgi_intercept_errors on;
               }
               location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
                       root /usr/share/;
               }
        }
        location /webmail {
               rewrite ^/* /squirrelmail last;
        }

If you use https instead of http for your vhost, you should add the line fastcgi_param HTTPS on; to your SquirrelMail configuration like this:

        location /squirrelmail {
               root /usr/share/;
               index index.php index.html index.htm;
               location ~ ^/squirrelmail/(.+\.php)$ {
                       try_files $uri =404;
                       root /usr/share/;
                       fastcgi_pass 127.0.0.1:9000;
                       fastcgi_param HTTPS on; # <-- add this line
                       fastcgi_index index.php;
                       fastcgi_param SCRIPT_FILENAME $request_filename;
                       include /etc/nginx/fastcgi_params;
                       fastcgi_param PATH_INFO $fastcgi_script_name;
                       fastcgi_buffer_size 128k;
                       fastcgi_buffers 256 4k;
                       fastcgi_busy_buffers_size 256k;
                       fastcgi_temp_file_write_size 256k;
                       fastcgi_intercept_errors on;
               }
               location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
                       root /usr/share/;
               }
        }
        location /webmail {
               rewrite ^/* /squirrelmail last;
        }

If you use both http and https for your vhost, you need to add the following section to the http {} section in /etc/nginx/nginx.conf (before any include lines) which determines if the visitor uses http or https and sets the $fastcgi_https variable (which we will use in our SquirrelMail configuration) accordingly (please note that you don't need to do this if you have added this section before, for example when you configured phpMyAdmin - see chapter 16):

vi /etc/nginx/nginx.conf

[...]
http {
[...]
        ## Detect when HTTPS is used
        map $scheme $fastcgi_https {
          default off;
          https on;
        }
[...]
}
[...]

Don't forget to reload nginx afterwards:

/etc/init.d/nginx reload

Then go to the nginx Directives field again, and instead of fastcgi_param HTTPS on; you add the line fastcgi_param HTTPS $fastcgi_https; so that you can use SquirrelMail for both http and https requests:

        location /squirrelmail {
               root /usr/share/;
               index index.php index.html index.htm;
               location ~ ^/squirrelmail/(.+\.php)$ {
                       try_files $uri =404;
                       root /usr/share/;
                       fastcgi_pass 127.0.0.1:9000;
                       fastcgi_param HTTPS $fastcgi_https; # <-- add this line
                       fastcgi_index index.php;
                       fastcgi_param SCRIPT_FILENAME $request_filename;
                       include /etc/nginx/fastcgi_params;
                       fastcgi_param PATH_INFO $fastcgi_script_name;
                       fastcgi_buffer_size 128k;
                       fastcgi_buffers 256 4k;
                       fastcgi_busy_buffers_size 256k;
                       fastcgi_temp_file_write_size 256k;
                       fastcgi_intercept_errors on;
               }
               location ~* ^/squirrelmail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
                       root /usr/share/;
               }
        }
        location /webmail {
               rewrite ^/* /squirrelmail last;
        }

 

 

25 Install ISPConfig 3

Before you start the ISPConfig installation, make sure that Apache is stopped (if it is installed - it is possible that some of your installed packages have installed Apache as a dependency without you knowing). If Apache2 is already installed on the system, stop it now...

/etc/init.d/httpd stop

... and remove Apache's system startup links:

chkconfig --del httpd

Make sure that nginx is running:

/etc/init.d/nginx restart

(If you have both Apache and nginx installed, the installer asks you which one you want to use: Apache and nginx detected. Select server to use for ISPConfig: (apache,nginx) [apache]:

Type nginx. If only Apache or nginx are installed, this is automatically detected by the installer, and no question is asked.)

Download the current ISPConfig 3 version and install it. The ISPConfig installer will configure all services like Postfix, Courier, etc. for you. A manual setup as required for ISPConfig 2 is not necessary anymore.

You now also have the possibility to let the installer create an SSL vhost for the ISPConfig control panel, so that ISPConfig can be accessed using https:// instead of http://. To achieve this, just press ENTER when you see this question: Do you want a secure (SSL) connection to the ISPConfig web interface (y,n) [y]:.

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:

[root@server1 install]# php -q install.php

To fix the Mailman errors you might get during the ISPConfig installation, open /usr/lib/mailman/Mailman/mm_cfg.py...

vi /usr/lib/mailman/Mailman/mm_cfg.py

... and set DEFAULT_SERVER_LANGUAGE = 'en':

[...]
#-------------------------------------------------------------
# The default language for this server.
DEFAULT_SERVER_LANGUAGE = 'en'
[...]

Restart Mailman:

/etc/init.d/mailman restart

Afterwards you can access ISPConfig 3 under http(s)://server1.example.com:8080/ or http(s)://192.168.0.100:8080/ (http or https depends on what you chose during installation). 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.

If you want to use IPv6 addresses with your nginx vhosts, please do the following before you create IPv6 vhosts in ISPConfig:

Open /etc/sysctl.conf...

vi /etc/sysctl.conf

... and add the line net.ipv6.bindv6only = 1:

[...]
net.ipv6.bindv6only = 1

Run...

sysctl -p

... afterwards for the change to take effect.
