Cant initialize MySQL. "mysqld_safe mysqld from pid file /var/run/mariadb/mariadb.pid ended" I am doing a fresh install of MySQL on Fedora 22.
After I run mysql_install_db I try to start the daemon using mysqld_safe but it does not work. The system says:

mysqld_safe Logging to '/var/log/mariadb/mariadb.log'.
mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
mysqld_safe mysqld from pid file /var/run/mariadb/mariadb.pid ended


How do I get this to work?

Here are the mariadb.log contents:
