port = 3360
datadir=/jzim/data_mysql/mysql  #/var/lib/mysql
socket=/jzim/data_mysql/mysql/mysql.sock

保存，重启服务，mysql -u root -p 登录出现如下问题

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

解决：

修改/etc/my.cnf

添加以下内容到/etc/my.conf:
[client]
socket = /Data/mydata/mysql.sock
[mysqld]

socket = /Data/mydata/mysql.sock

重启服务，OK
