Remember once MySQL boot failure Can ' t connect to local MySQL server through socket

Remember once MySQL boot failure Can ' t connect to local MySQL server through socket '/var/lib/mysql/mysql.sock '

Failure phenomena:

[[email protected] ~]# mysql -uroot -penter password: error 2002  (HY000):  can ' t connect to local mysql server through socket  '/var /lib/mysql/mysql.sock '   (2) [[email protected] ~]# [[email protected] ~]#  service mysqld restartstopping mysqld:                                             [   Ok  ]mysql daemon failed to start. starting mysqld:                                             [failed][[email protected] ~]# 

Find out where MySQL's error log is

Parsing errors

Search for a while, also did not find the right solution, but see a lot of selinux figure

Try to close SELinux

[[email protected] ~]# getenforce enforcing[[email  protected] ~]# setenforce 0[[email protected] ~]# getenforce  permissive[[email protected] ~]# service mysqld restartstopping mysqld:                                              [  OK  ]Starting mysqld:                                              [  ok  ] 

The problem is not solved directly, but around the past, there is time to chew again, first of all to do the thing at hand.
