本文详细描述了一种解决MySQL启动时出现“服务器在未更新PID文件的情况下退出”错误的方法，涉及卸载并清理旧版本，删除相关配置文件及目录，重新安装MySQL并设置启动脚本。

mysql.server start

报错：The server quit without updating PID file (/usr/local/var/mysql/zhangzhenxingdeMacBook-Pro.local.pid).

最后还是重新安装！！以前数据库内容丢失。

I think one can end up in this position with older versions of mysql already installed. I had the same problem and none of the above solutions worked for me. I fixed it thus:

Used brew’s remove & cleanup commands, unloaded the launchctl script, then deleted the mysql directory in /usr/local/var , deleted my existing /etc/my.cnf (leave that one up to you, should it apply) and launchctl plist

Updated the string for the plist. Note also your alternate security script directory will be based on which version of MySQL you are installing.

Step-by-step:

1 brew remove mysql
2 
3 brew cleanup
4 
5 launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
6 
7 rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
8 
9 sudo rm -rf /usr/local/var/mysql

I then started from scratch:

installed mysql with brew install mysql

ran the commands brew suggested:

1 unset TMPDIR
2 
3 mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

Start mysql with mysql.server start command, to be able to log on it

Used the alternate security script:

/usr/local/Cellar/mysql/5.5.10/bin/mysql_secure_installation

Followed the launchctl section from the brew package script output such as,

#start
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

#stop
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

Boom.

Hope that helps someone!
