# 打开终端： #

安装mysql:

> brew install mysql  
>

设置mysql为开机启动项目:

> ln -sfv /usr/local/opt/mysql/\*.plist ~/Library/LaunchAgents  
>

启动mysql

> mysql.server start  
>

设置密码：

> mysql\_secure\_installation  
>

运行mysql\_secure\_installation会执行几个设置：

a)为root用户设置密码

b)删除匿名账号

c)取消root用户远程登录

d)删除test库和对test库的访问权限

e)刷新授权表使修改生效

代码如下：

> \[root@server1 ~\]\# mysql\_secure\_installation  
>

设置完，可以安装一个 MySQLWorkbench 就可以可视化操作数据库了。
