The installation of Kolab Groupware on Red Hat Enterprise Linux installs a number of additional packages, from the EPEL software repository.

Installation Procedure¶

Install the EPEL repository:

# rpm -Uhv https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Install the Kolab Groupware repository configuration:

# cd /etc/yum.repos.d/
# wget http://obs.kolabsys.com/repositories/Kolab:/16/RHEL_7/Kolab:16.repo

Import the GPG key used to sign the packages:

# rpm --import https://ssl.kolabsys.com/community.asc

Install the yum-plugin-priorities package:
```
# yum install yum-plugin-priorities
```
Make sure that the packages from the Kolab repositories have a higher priority than eg. the EPEL packages:
```
# for f in /etc/yum.repos.d/Kolab*.repo; do echo "priority = 60" >> $f; done
```

Install Kolab Groupware:

# yum install --enablerepo=rhel-7-server-optional-rpms kolab
