Mac 启动mysql报错:Can't connect to local MySQL server through socket '/tmp/mysql.sock'

背景:

    许久不打开本地mysql连接,今天突然连接不上了,报错:

➜  ~ mysql -version
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)  

过程:

 百度都说是mysql.sock的文件,建议把 /tmp下的两个文件干掉就好了,但感觉跟我的问题没多大关系,看到很多人说不知道在哪里去找sock文件,mac系统其实用find命令就好了,

➜  ~ find / -name mysql.sock
find: /usr/sbin/authserver: Permission denied
find: /usr/local/var/run/nginx/scgi_temp: Permission denied
find: /usr/local/var/run/nginx/uwsgi_temp: Permission denied
find: /usr/local/var/run/nginx/proxy_temp: Permission denied
find: /usr/local/var/run/nginx/fastcgi_temp: Permission denied
find: /usr/local/var/run/nginx/client_body_temp: Permission denied
find: /.Spotlight-V100: Permission denied
find: /Library/Application Support/Apple/ParentalControls/Users: Permission denied

  然后许多人说不知道怎么更改,其实可以这么改,根据上面find找到sock目录后,假如:

➜  ~ find / -name mysql.sock
/var/lib/mysql/mysql.sock

目录在/var/lib/mysql/mysql.sock这个位置,则需要修改my.cnf文件

➜  ~ vi /usr/local/mysql/my.cnf

[client]
character-set-server = utf8
port    = 3306
socket  = /var/lib/mysql/mysql.sock

  保存退出后,重启mysql服务即可!!


 

  

方案: 

1. 先看看安装目录

➜  ~ which mysql
/usr/local/bin/mysql

 既然安装目录存在,则有安装

2.在看下运行状态

➜  tmp ps -ef |grep mysql

 发现没在运行

3.直接启动

➜  ~ mysql.server start

Starting MySQL
... SUCCESS! 

 好了,原来是没启动,问题解决,然后widow系统的话是用

service mysql start
