1、先通过:service  mysqld  status  查看mysql是否启动

      (没装mysql service 也可通过 /etc/rc.d/init.d/mysqld status查看)

      若没启动,则启动mysql:service  mysqld  start

2、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

(注意:红色标记部分文件路径必须相同)

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 &
