23 Install RoundcubeMail
To install the Roundcube webmail client, run...
yum -y install roundcubemail
ISPConfig contains a default webmail alias for squirremail inside its apps vhost. We will use that alias for the more modern roundcube, so we create a symlink with the name squirrelmail in /usr/share
ln -s /usr/share/roundcubemail /usr/share/squirrelmail
After you have installed ISPConfig 3, you can access RoundcubeMail as follows:
The ISPConfig apps vhost on port 8081 for nginx comes with a /webmail alias configuration, so you can use http://server1.example.com:8081/webmail to access RoundcubeMail.
If you want to use a /webmail or /roundcubemail 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:
To do this, paste the following into the nginx Directives field on the Options tab of the web site in ISPConfig:
location /roundcubemail {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/roundcubemail/(.+\.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 $fastcgi_script_name;
fastcgi_buffer_size 128k;
fastcgi_buffers 256 4k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
}
location ~* ^/roundcubemail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /webmail {
rewrite ^/* /roundcubemail last;
}
If you use https instead of http for your vhost, you should add the line fastcgi_param HTTPS on; to your RoundcubeMail configuration like this:
location /roundcubemail {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/roundcubemail/(.+\.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 $fastcgi_script_name;
fastcgi_buffer_size 128k;
fastcgi_buffers 256 4k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
}
location ~* ^/roundcubemail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /webmail {
rewrite ^/* /roundcubemail last;
}
If you use both http and https for your vhost, you can use the $https variable - go to the nginx Directives field again, and instead of fastcgi_param HTTPS on; you add the line fastcgi_param HTTPS $https; so that you can use RoundcubeMail for both http and https requests:
location /roundcubemail {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/roundcubemail/(.+\.php)$ {
try_files $uri =404;
root /usr/share/;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param HTTPS $https; # <-- add this line
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
include /etc/nginx/fastcgi_params;
fastcgi_param PATH_INFO $fastcgi_script_name;
fastcgi_buffer_size 128k;
fastcgi_buffers 256 4k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_intercept_errors on;
}
location ~* ^/roundcubemail/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /webmail {
rewrite ^/* /squirrelmail last;
}
Now we need a database for roundcube mail, we will initialise it as follows:
mysql -u root -p
At mariadb prompt use:
CREATE DATABASE roundcubedb;
CREATE USER roundcubeuser@localhost IDENTIFIED BY 'roundcubepassword';
GRANT ALL PRIVILEGES on roundcubedb.* to roundcubeuser@localhost ;
FLUSH PRIVILEGES;
exit
I am using details for roundcube database as a test, please replace the values as per your choice for security reasons. We will finish the roundcube installation after we installed ISPConfig.
24 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...
systemctl stop httpd.service
... and remove Apache's system startup links:
systemctl disable httpd.service
Make sure that nginx is running:
systemctl restart nginx.service
(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, Dovecot, 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':

Restart Mailman:
systemctl restart mailman.service
Now I will finish the RoundcubeMail installation. Open the following URL in your browser:
http://192.168.0.100:8081/roundcubemail/installer
you will be greeted by the RoundcubeMail web installer, scroll down the page and click next:
Then enter the database details of the roundcubedb database that we created in chapter 23 here:
An set the SMTP server to localhost and set your preferred language
and click on "Create config" to go to the next page.
Open the file /etc/roundcubemail/config.inc.php on the shell:
nano /etc/roundcubemail/config.inc.php
and paste the configuration that is shown in the web installer into that file and save the file.

Then go back to the web installer and click on the continue button. On this page, click on "initialize database":
The page should look like this after successfull initialisation of the database:
To protect the RoundcubeMail configuration from unauthorized modifications, I'll remove the installer folder by running this command on the shell:
rm -rf /usr/share/roundcubemail/installer
25 First ISPConfig Login
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):
Next we have to adjust the BIND configuartion paths in ISPConfig. Click on "System" in the upper menu, then on "Server config" in the right menu. In the list that appears then on the left side, click on the server name.
Go to the "DNS" tab of the form:
and enter the DNS paths as follows:
BIND zonefiles directory: /var/named
BIND named.conf path: /etc/named.conf
BIND named.conf.local path: /etc/named.conf.local
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.
25.1 ISPConfig 3 Manual
In order to learn how to use ISPConfig 3, I strongly recommend to download the ISPConfig 3 Manual.
On more than 300 pages, it covers the concept behind ISPConfig (admin, resellers, clients), explains how to install and update ISPConfig 3, includes a reference for all forms and form fields in ISPConfig together with examples of valid inputs, and provides tutorials for the most common tasks in ISPConfig 3. It also lines out how to make your server more secure and comes with a troubleshooting section at the end.
