Mac通过brew安装的MySQL各种无法运行问题总结

一、解决 ERROR! The server quit without updating PID file (/usr/local/var/mysql/xxx.local.pid).

参考：https://stackoverflow.com/a/36156848

问题描述

之前用的好好的，经过一次更新（5.6->8.0）后某一天突然炸了。通过brew services start mysql启动 MySQL 后，使用 Navicat 连接提示：

1
2003 - Can't connect to MySQL server on '127.0.0.1' (61 "Connection refused")

经过一番查询，据说是 MySQL 服务没启动的问题（其实我觉得这说法有点不对），然后我就尝试启动MySQL服务，命令mysql.server start。接着我收到以下错误：

1
ERROR! The server quit without updating PID file (/usr/local/var/mysql/xxx.local.pid).

xxx为我的机器名字。

然后执行mysql_secure_installation又提示：

1

4
Securing the MySQL server deployment.

Enter password for user root:
Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

后来经过各种尝试如：

rm /usr/local/var/mysql/*.err
rm /usr/local/var/mysql/xxx.local.err
find / -name mysql.sock
sudo chmod -R 755 /usr/local/var/mysql/
sudo chown -R _mysql:mysql /usr/local/var/mysql
ls -laF /usr/local/var/mysql/
sudo rm -f /tmp/mysql.sock.lock
ls -laF /tmp

还有通过ps aux | grep mysql找出 MySQL 的 PID，再用kill -9 [PID]杀掉进程都没用。

最终解决方法：重装大法

最后尝试完全重新安装 MySQL 终于解决了。 **警告：**这将删除所有数据库，因此请确保先保存转储。

brew remove mysql
brew cleanup --force
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /usr/local/var/mysql

brew install mysql
mysqld --initialize --explicit_defaults_for_timestamp
mysql.server start # no sudo!

重装了MySQL后建议重新执行一次配置脚本：mysql_secure_installation

注意：安装后必须执行
1
mysqld --initialize --explicit_defaults_for_timestamp
否则仍无法解决以下问题：
1
Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
