mac下进行web开发, mysql算是必备程序了. 

1. 如何安装mysql? 

brew install mysql

2. 如何启动mysql? 

mysqld &mysql.server start

3. 如何让mysql开机自启动

mkdir -p ~/Library/LaunchAgentscp `brew --prefix mysql`/*.plist ~/Library/LaunchAgents/launchctl load -w ~/Library/LaunchAgents/*.plist

4. 重启后, 测试是否成功

mysql -uyour_username -pyour_password

5. 如果失败了: 

ls `brew --prefix mysql`/*.err# 如果有 *.err, 删除. 重启机器. # 如果没有. 全部加入sudo执行步骤3.
