MySQL 报 Can 't connect to local

报错

Can 't connect to local MySQL server through socket '/tmp/mysql.sock '(2) "

Can 't connect to local MySQL server through socket '/tmp/mysql.sock '(111) "

my.cnf

查看安装目录下的 /conf/my.cnf 文件

socket=/data/mysql/tmp/mysql.sock

原来里面指定的 socket 位于 /data/mysql/tmp/mysql.sock

解决

cd /tmp
ln -s /data/mysql/tmp/mysql.sock mysql.sock
