安装 mysql-5.7.12-osx10.11-x86_64.pkg

mac下的默认安装路径/usr/local/mysql/bin

初次安装会分配一个随机密码给root用户(会有提示, root@local:之后的才是root密码)



安装完成后，在系统偏好设置里面,点击mysql图标，启动mysql服务





登录

{{{class="brush: shell"

cd /usr/local/mysql/bin

./mysql -u root -p
Enerpasswd: 此处输入root随机密码

}}}

修改密码

{{{class="brush: shell"
mysql>  SET PASSWORD = PASSWORD('louis866549');
