fedora 22 mysql won't run

edit

I have tried this.But unfortunately the result is;

[root@localhost msd]# su -c 'systemctl start mariadb.service'
Failed to start mariadb.service: Unit mariadb.service failed to load: No such file or directory.
[root@localhost msd]# 

Did you install the DBMS?

su -c 'dnf install -y mysql-server'

Yes, I've tried again.But;

[root@localhost msd]# su -c 'dnf install -y mysql-server'
Failed to synchronize cache for repo 'mysql56-community' from 'http://repo.mysql.com/yum/mysql-5.6-community/fc/22/x86_64/': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried, disabling.

Ok, you installed the MySQL using the mysql.com repository, but there isn't any repository for the f22 brach, which is still under development. You can disable the mysql.com repository and use the main fedora repository to avoid that issue. In any case, are you interested in replacing your current DBMS with MariaDB, or you would like to use the Oracle's implementation?

su -c 'dnf --releasever=21 distro-sync'
