在Linux安装MySQL有时候会出现[mysql]ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) 这样的错误,具体解决办法如下:
[root@www ~]# rm -rf /var/lib/mysql/*
[root@www ~]# rm /var/lock/subsys/mysqld
rm: remove regular empty file `/var/lock/subsys/mysqld'? y
[root@www ~]# killall mysqld
[root@www ~]# service mysqld start
[root@www ~]# /etc/rc.d/init.d/mysqld status
mysqld (pid 5457) is running...

[root@r710-1 /]# mysql -u root

当用户在执行mysql时报错
"ERROR 2002 (HY000): Cant connect to local MySQL server through socket /tmp/mysql.sock (2)"
原因是由于mysql 的mysql.sock 默认是在/var/lib/mysql/mysql.sock下,但linux系统总是去/tmp/mysql.sock查找,如果mysql.sock不存在,系统就会报错。
解决办法:
1.直接指定mysql通道
[root@localhost ~]# find / -name mysql.sock
/var/lib/mysql/mysql.sock
[root@localhost ~]# mysql --socket=/var/lib/mysql/mysql.sock
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2 to server version: 5.0.22
Type help; or \h for help. Type \c to clear the buffer.

2. 为mysql.sock创建软连接(类似快捷方式)
[root@localhost ~]# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
[root@localhost ~]# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.

Type help; or \h for help. Type \c to clear the buffer.
