MySQL无法启动 [英] MySQL won't start

问题描述

当我尝试启动MySQL时，我得到:

When I try to start MySQL I get:

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

当我使用sudo时，我得到:

When I use sudo I get:

Starting MySQL
. ERROR! The server quit without updating PID file (/usr/local/var/mysql/Victorias-MacBook-Pro.local.pid).

我正在使用Mac OS X 10.7.我通过自制软件安装了MySQL，并安装了MySQL 5.5.20.

I am working with Mac OS X 10.7. I installed MySQL through homebrew and I installed MySQL 5.5.20.

这是我得到的.err文件:

推荐答案

删除此pid文件，确保所有实例均已停止(杀死所有未关闭的进程)，检查是否在侦听MySQL端口3306(netstat应该有帮助) )，然后尝试重新启动MySQL.

Remove this pid file, make sure all the instances are stopped (kill any processes not going down), check nothing is listening the MySQL port 3306 (netstat should help) and try to start MySQL again.
