mac brew 安装 mysql

安装MySql

$ brew install mysql

设置MySql开机启动

$ mkdir -p ~/Library/LaunchAgents    # 首先确认该目录是否存在，若已经存在不用执行本命令   $ ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents   $ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

启动MySql服务

$ mysql.server start  

错误修复
如果在启动过程中出现如下错误：ERROR! The server quit without updating PID file，使用以下方法修复。

$ sudo chmod -R 755 /usr/local/var/mysql

若仍不能启动，tail -f …pid 查看pid.err保错文件
InnoDB: Table flags are 0 in the data dictionary but the flags in file ./ibdata1 are 0x4800!

先前安装的mysql8创建了坏的DB文件，必须手动删除 rm -rf /usr/local/var/mysql brew uninstall mysql@5.7 brew install mysql@5.7

使用Homebrew卸载MySql

$ brew remove mysql $ brew cleanup $ launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist $ rm -Rf ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
