Plugins » Katello

On RHEL7 systems MariaDB is the default DB rather than MySQL. However katello-installer is trying to install MySQL when --foreman-db-type=mysql is set.

Here is the relevant snippet from /usr/share/katello-installer/modules/mysql/manifests/params.pp

case $::osfamily {
'RedHat': {
if $::operatingsystem 'Fedora' and (is_integer($::operatingsystemrelease) and $::operatingsystemrelease >= 19 or $::operatingsystemrelease "Rawhide") {
$client_package_name = 'mariadb'
$server_package_name = 'mariadb-server'
} else {
$client_package_name = 'mysql'
$server_package_name = 'mysql-server'
}

So installer should also install mariadb and mariadb-server packages when operatingsystem is Redhat (or CentOS) and operatingsystemrelease is 7. Because in RHEL7 repos there is no mysql and mysql-server packages.
