　　在bash执行

　　"systemctl start mysqld"

     提示：

　　“Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.”

     

/var/lib/mysql权限问题。cd目录，执行以下，解决：

bash-4.2#     setenforce 0

bash-4.2#    chown -R mysql:mysql /var/lib/mysql

bash-4.2#    chmod -R 777 /var/lib/mysql

bash-4.2#   systemctl start mysqld.service

bash-4.2#    ps -ef |grep mysql

 

    再执行：

 

systemctl start mysqld.service

 

 

运行啦

mysql     3476     1  0 09:49 ?        00:00:00 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid
