The Perfect Server - Debian 9 (Nginx, BIND, Dovecot, ISPConfig 3.1) - Page 3

18 Install RoundCube

Install RoundCube with this command:

apt-get install roundcube roundcube-core roundcube-mysql roundcube-plugins

The installer will ask the following questions:

Configure database for roundcube with dbconfig.common? <-- yes
MySQL application password for roundcube: <-- press enter
Password of the databases administrative user: <-- enter the MySQL root password here.

Then edit the RoundCube /etc/roundcube/config.inc.php file and adjust a few settings:

nano /etc/roundcube/config.inc.php

Set the default_host and smtp_server to localhost.

$config['default_host'] = 'localhost';
$config['smtp_server'] = 'localhost';

ISPConfig has some configuration in the nginx apps vhost for squirrelmail which works for roundcube as well. We activate it with:

ln -s /usr/share/roundcube /usr/share/squirrelmail

Now you can access RoundCube as follows:

http://192.168.1.100:8081/webmail
http://server1.example.com:8081/webmail (after you have installed ISPConfig, see the next chapter)

19 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...

service apache2 stop

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

update-rc.d -f apache2 remove

Make sure that nginx is running:

service 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.)

To install ISPConfig 3.1 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, Niginx, Dovecot, etc. for you.

# php -q install.php

Installation completed.

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

Afterward you can access ISPConfig 3 under http(s)://server1.example.com:8080/ or http(s)://192.168.1.100:8080/ ( 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.

21 Additional Notes

21.1 OpenVZ

If the Debian 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 Virtual machine image download of this tutorial

This tutorial is available as ready to use virtual machine image in ovf/ova format that is compatible with VMWare and Virtualbox. The virtual machine image uses the following login details:

SSH / Shell Login

Username: administrator
Password: howtoforge

Username: root
Password: howtoforge
