PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password ‘new-password‘
/usr/bin/mysqladmin -u root -h c1.local password ‘new-password‘
See the manual for more instructions.
Please report any problems with the /usr/bin/mysqlbug script!

Starting MySQL................................... ERROR!
这个报错是selinux引起的，修改
/etc/selinux/config中：
把SELINUX=enforcing
改为：SELINUX=disabled
保存，重启机器后mysql已经启动完毕。
