Не может загрузить Mysql на Centos 7

Я установил mysql на Centos 7 (mysql-community-server) как корень. Проблема состоит в том, что я не могу запустить, демон с "сервисом mysqld запускаются", Он никогда не возвращает меня для запроса и даже если я пытаюсь использовать другую ssh сессию, которая демон не.

Это - вывод, я получаю с хвостом "/var/log/mysqld.log":

Я попытался отключить SELinux, но он не работает ни один. Я не знаю то, что продолжается...

Я буду действительно ценить Вашу справку. Thankss
