Mac下安装MySQL

Mac下安装MySQL简单到想哭，基本上就是brew搜索一下，安装，启动，即可。

$ brew install mysql
$ mysql.server start

如果想停止，可以使用：

$ mysql.server stop

以下是我的机器上，brew search/info的输出，尤其是最后的启动命令，很有用。

bash-3.2$ brew search mysql

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

MySQL is configured to only allow connections from localhost by default

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
