Installation of Kolab Enterprise 13 on Red Hat Enterprise Linux 6

The installation of Kolab Groupware on Red Hat Enterprise Linux installs a number of additional packages, from the EPEL software repository, and the repositories for the Kolab Enterprise edition, provided by Kolab Systems AG.

Installation Procedure

  1. Copy the client SSL certificate and key you have obtained from Kolab Systems AG as per the instructions listed on [1], summarized here for your convenience:

    1. Remove the passphrase from the SSL certificate key:

      # openssl rsa -in /path/to/private.key \
          -out /path/to/private.key.nopass
      
    2. Concatenate the certificate file and the new key file without passphrase:

      # cat /path/to/public.crt /path/to/private.key.nopass \
          > /path/to/mirror.kolabsys.com.client.pem
      
    3. Place the file mirror.kolabsys.com.ca.cert in /etc/pki/tls/certs/.

    4. Place the file mirror.kolabsys.client.pem in /etc/pki/tls/private/, and correct the permissions:

      # chown root:root /etc/pki/tls/private/mirror.kolabsys.com.client.pem
      # chmod 640 /etc/pki/tls/private/mirror.kolabsys.com.client.pem
      
  2. Install the EPEL repository:

    # rpm -Uhv https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
    
  3. Obtain a copy of the GPG signature used to sign packages:

    # rpm --import https://ssl.kolabsys.com/santiago.asc
    
  4. Install the Kolab Enterprise repository configuration package:

    # yum install https://ssl.kolabsys.com/kolab-enterprise-13-for-el6.rpm
    
  5. Install Kolab Enterprise:

    # yum install kolab
    
  6. Do not forget to also execute yum update.

Continue to Kolab Groupware Setup.
