In order to enable developers at the Kolab Technology Sprint to work on the same brand new code and to have a common platform, we have released a pre-alpha version of Kolab 3.0. This version is only intented for development and should never ever be used on a production system since it might do all sorts of nasty unexpected things such as eating your children and causing a word-wide financial collapse.
Here is a quick HOWTO by Jeroen van Meeuwen on installing and configuring the pre-alpha release of Kolab 3.0 on a CentOS 6.3 system. The setup is actually quite similar to installing Kolab 2.4 on CentOS 6.2.
Install the epel-release package. At the time of this writing, this means executing:
# rpm -Uvh http://mirror.switch.ch/ftp/mirror/epel/6/i386/epel-release-6-7.noarch.rpm
Install the kolab-3.0-community-release package. At the time of this writing, this means executing:
# rpm -Uvh http://mirror.kolabsys.com/pub/redhat/kolab-3.0/el6/development/i386/kolab-3.0-community-release-6-1.el6.kolab_3.0.noarch.rpm
Install the kolab-3.0-community-release-development package. At the time of this writing, this means executing:
# rpm -Uvh http://mirror.kolabsys.com/pub/redhat/kolab-3.0/el6/development/i386/kolab-3.0-community-release-development-6-1.el6.kolab_3.0.noarch.rpm
Install Kolab Groupware like so:
# yum install kolab
Setup Kolab with a minimal amount of interference:
This will setup Kolab Groupware including LDAP, Postfix, Cyrus IMAP, Roundcube, Free/Busy and ActiveSync using the information available on the system and a minimal amount of input. For greater flexibility during the setup process, please read the Configuration chapter in the documentation.
