MySQL在OS El Capitan的配置[PID file error]

Installation

使用Homebrew安装:

brew install mysql

bash中显示如下信息,安装成功。

We've installed your MySQL database without a root password. To secure it run:

mysql_secure_installation

To connect run:

mysql -uroot

To have launchd start mysql now and restart at login:

brew services start mysql

Or, if you don't want/need a background service you can just run:

mysql.server start

运行之后显示错误信息

LINSPIRATIONs-MacBook-Pro:~ linspiration$ mysql.server start
Starting MySQL
. ERROR! The server quit without updating PID file (/usr/local/var/mysql/LINSPIRATIONs-MacBook-Pro.local.pid).

Configuration

我没有按照网上大部分的解决方案那样去对local.err或者PID进行修改,而是

1.

 //删除usr/local中之前的安装文件夹,并用brew进行卸载
 brew uninstall mysql
 //如未解决问题,进行下一步

2.

 //在bash中找到所有的mysql instance
 ps -ef | grep mysql

3.

//关闭进程PID,PID为最后一行的
--pid-file=/usr/local/var/mysql/LINSPIRATIONs-MacBook-Pro.local.pid    501 76360 76349   0 10:08PM ttys000    0:00.00 grep mysql
//中的501 76360 76349
//然后 kill掉它

kill -9 501 76360 76349

4.

//重新运行sql server
mysql.server start

完成!
