Failed to start mariadb.service: Access denied

I did a fresh install of fedora 22, then I installed dnf install mariadb-server.

After that I tried to start the service

systemctl start mariadb
Failed to start mariadb.service: Access denied

I know this is an issue wuth selinux, if I disable selinux everything works fine.

This is the error on messages
Oct 1 13:05:48 soprano audit: <audit-1107> pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='avc: denied

and on audit.log

Is there a way to start fedora, without disable selinux.

Thanks
