重启mysql服务器后报:ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

原因my.cnf配置文件加了 socket = /usr/local/mysql/mysql.sock 

注释后解决

新解决方法

mysql安装目录bin/mysql_config默认的socket路径是/tmp/mysql.sock

socket=' /tmp/mysql.sock'

将my.cnf配置文件的修改未一样的路径即可

[client]socket = /tmp/mysql.sock[mysql]socket = /tmp/mysql.sock
