今天重装在centos 的linux上重装了mysql，然后发现报了如下错误：

Job for mysqld.service failed because the control process exited with error code.

原因有很多，具体要看日志记录信息，解决方法如下：

求助大佬,mysql启动失败，报错：Job for mysqld.service failed - SegmentFault 思否 

如果上面都不行，那只能采取：删除mysql下面的所有路径

rm -rf /var/lib/mysql/*

 该方法会删除 mysql 数据，慎用！慎用！慎用！！！！！！！！！！！！！！！！！ 

重新启动mysql，再次查看mysql状态。
