标签：server   service   error   through   local   

报错信息：ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/tmp/mysql.sock‘ (2)

[root@mysql5 ~]# mysql -uroot -pxxxx

ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/tmp/mysql.sock‘ (2)

[root@mysql5 ~]# 

[root@mysql5 ~]# 

[root@mysql5 ~]# 

[root@mysql5 ~]# service mysqld3306 restart

 ERROR! MySQL server PID file could not be found!

Starting MySQL. ERROR! The server quit without updating PID file (/data/mysql3306/data/mysql5.5.pid).

[root@mysql5 ~]# 

确定是配置文件有错误，注意查看配置的更改：

[root@mysql5 ~]# 

[root@mysql5 ~]# service mysqld3306 start  

Starting MySQL. ERROR! The server quit without updating PID file (/data/mysql3306/data/mysql5.5.pid).

[root@mysql5 ~]# 

[root@mysql5 ~]# vi /etc/my.cnf

[root@mysql5 ~]# service mysqld3306 start

Starting MySQL.. SUCCESS! 

[root@mysql5 ~]# 

其实我们可以通过查看报错日志来确定是哪里的错误：

-----------------------------------------------------------------------------

也可以是其他的报错信息，注意查找error报错信息即可。
