Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ 解决方法

启动mysql 报错：

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)

1、先查看 /etc/rc.d/init.d/mysqld status 看看m y s q l 是否已经启动.

另外看看是不是权限问题.

2、确定你的mysql.sock是不是在那个位置，

mysql -u 你的mysql用户名 -p -S /var/lib/mysql/mysql.sock

3、试试：service mysqld start

4、如果是权限问题，则先改变权限 #chown -R mysql:mysql /var/lib/mysql

[root@localhost ~]# /etc/init.d/mysqld start

启动 MySQL： [ 确定 ]

[root@localhost ~]# mysql -uroot -p

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

原因是，/var/lib/mysql 的访问权限问题。

shell> chown -R mysql:mysql /var/lib/mysql

接着启动服务器

shell> /etc/init.d/mysql start

服务器正常启动后察看 /var/lib/mysql 自动生成mysql.sock文件。

但是我的问题仍然没有得到解决。

问题终于解决：方法： 修改/etc/my.conf:[mysqld]

datadir=/usr/local/mysql/data

socket=/var/lib/mysql/mysql.sock

[mysql.server]

user=mysql

basedir=/usr/local/mysql

If there is not currently a section called [client], add one at the bottom of the file and copy the socket= line under the [mysqld] section such as:

[client]

socket=/var/lib/mysql/mysql.sock

发现依旧如此，运行/etc/init.d/mysql start报错： Starting MySQLCouldn't find MySQL manager or server 是mysqld服务没启，运行/usr/local/mysql/bin/mysqld_safe &

问题解决。
