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。
