23 Install Roundcube webmail

To install the Roundcube webmail client, run...

yum -y install roundcubemail

Change the roundcubemail configuration file as follows:

vi /etc/httpd/conf.d/roundcubemail.conf

#
# Round Cube Webmail is a browser-based multilingual IMAP client
#

Alias /roundcubemail /usr/share/roundcubemail
Alias /webmail /usr/share/roundcubemail

# Define who can access the Webmail
# You can enlarge permissions once configured

#<Directory /usr/share/roundcubemail/>
#    <IfModule mod_authz_core.c>
#        # Apache 2.4
#        Require local
#    </IfModule>
#    <IfModule !mod_authz_core.c>
#        # Apache 2.2
#        Order Deny,Allow
#        Deny from all
#        Allow from 127.0.0.1
#        Allow from ::1
#    </IfModule>
#</Directory>

<Directory /usr/share/roundcubemail/>
        Options none
        AllowOverride Limit
        Require all granted
</Directory>

# Define who can access the installer
# keep this secured once configured

#<Directory /usr/share/roundcubemail/installer/>
#    <IfModule mod_authz_core.c>
#        # Apache 2.4
#        Require local
#    </IfModule>
#    <IfModule !mod_authz_core.c>
#        # Apache 2.2
#        Order Deny,Allow
#        Deny from all
#        Allow from 127.0.0.1
#        Allow from ::1
#    </IfModule>
#</Directory>

<Directory /usr/share/roundcubemail/installer>
        Options none
        AllowOverride Limit
        Require all granted
</Directory>


# Those directories should not be viewed by Web clients.
<Directory /usr/share/roundcubemail/bin/>
    Order Allow,Deny
    Deny from all
</Directory>
<Directory /usr/share/roundcubemail/plugins/enigma/home/>
    Order Allow,Deny
    Deny from all
</Directory>
~              

Restart Apache:

systemctl restart httpd.service

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 [email protected] IDENTIFIED BY 'roundcubepassword';
GRANT ALL PRIVILEGES on roundcubedb.* to [email protected] ;
FLUSH PRIVILEGES;
exit

I am using details for roundcube database as a test, please replace the values as per your choice for security reasons.

Now we will install the roundcube on browser at http://192.168.1.100/roundcubemail/installer

Now fill the entries for the

nano /etc/roundcubemail/config.inc.php

<?php

/* Local configuration for Roundcube Webmail */

$config['spellcheck_engine'] = 'pspell';

Then press on the button "continue" in the web installer. On the following page, press on the button "Initialize database".

Finally, disable the Roundecubemail installer. Change the apacheroundcubemail configuration file:

vi /etc/httpd/conf.d/roundcubemail.conf

#

~              

Restart Apache:

systemctl restart httpd.service

24 Install ISPConfig 3

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:

[[email protected] install]# php -q install.php

The error message "usage: doveadm [-Dv] [-f <formatter>] <command> [<args>]" can be ignored, in case that you get it during ispconfig installation.

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:

systemctl restart mailman.service

Afterwards 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.
