How to Install Kolab on OpenSUSE Latest

Kolab is a free and open-source groupware software suite, it provides a wide range of functionalities for email, calendaring, tasks, address books, file sharing, and more. OpenSUSE is a leading and stable Linux distribution that provides all the necessary tools to run Kolab.

In this tutorial, we will guide you through the steps to install Kolab on OpenSUSE latest version.

Prerequisites

• OpenSUSE Latest version installed
• Root access or sudo privileges
• Access to the internet

Step 1 - Install Required Packages

The first step is to install the required packages for Kolab. Open a terminal window and update your system by running the following command:

zypper update

Then, install the following packages:

zypper install apache2 mysql-server php7 php7-mysql php7-imap php7-ldap php7-pear kolab

This command will install the Apache web server, MySQL database server, PHP 7 and its necessary libraries, and Kolab groupware software.

Step 2 - Configure MySQL

After installing the MySQL database server, you need to set a root password.

mysql_secure_installation

You will be prompted to set a root password, remove anonymous users, restrict root login remotely, and remove test databases.

Once completed, you can login to the MySQL server with the following command:

mysql -u root -p

Step 3 - Configure Apache

After installing the Apache web server, you need to configure it to work with Kolab. First, you need to enable the Apache modules: mod_php, mod_rewrite, and mod_ssl.

a2enmod ssl php7

Next, create a new virtual host configuration file for Kolab:

nano /etc/apache2/vhosts.d/kolab.conf

Include the following content:

<VirtualHost _default_:443>
  ServerAdmin admin@example.com
  ServerName example.com
  DocumentRoot /usr/share/kolab-webadmin
  ErrorLog /var/log/apache2/kolab-error.log
  CustomLog /var/log/apache2/kolab-access.log combined

  SSLEngine on
  SSLCertificateFile /etc/pki/tls/certs/server.crt
  SSLCertificateKeyFile /etc/pki/tls/private/server.key

  <Directory "/usr/share/kolab-webadmin">
    Options -Indexes +FollowSymLinks
    AllowOverride All
    Require all granted
  </Directory>
</VirtualHost>

Make sure to replace example.com with your domain name. Then, save and close the file.

Finally, restart the Apache server to reflect the changes:

systemctl restart apache2

Step 4 - Configure Kolab

Now, you need to configure Kolab to work with your Apache and MySQL servers. First, create a new configuration file:

nano /etc/kolab/kolab.conf

Include the following content:

[ldap]
ldap_uri = ldaps://localhost:636
ldap_base_dn = dc=example,dc=com
ldap_bind_dn = uid=kolab-service,ou=Special Users,dc=example,dc=com
ldap_bind_pw = <password>

[cyrus-imap]
imap_admin_user = cyrus-admin@example.com
imap_admin_pass = <password>

[kolab]
default_locale = en_US.UTF-8
default_timezone = UTC

mysql_root_password = <password>

hostname = example.com
timezone = America/Los_Angeles

Make sure to replace example.com with your domain name and set the passwords accordingly.

Next, initialize the Kolab database:

/usr/sbin/setup-kolab

This command will create a new Kolab database in MySQL and install the necessary schema.

Finally, start the Kolab services:

systemctl start kolab-saslauthd.service
systemctl start kolabd.service
systemctl start httpd.service

Step 5 - Access Kolab Web Interface

Now, you can access the Kolab web interface by visiting https://example.com. You should see the Kolab login page. Login with your administrative credentials, and you will be redirected to the Kolab Dashboard.

Congratulations! You have successfully installed Kolab on OpenSUSE latest version. Now, you can manage your email, calendars, tasks, and more.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
