MAC 系统环境配置记录

安装mysql

brew install mysql

 

 

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

 

 

开启安全模式

mysqld_safe --skip-grant-tables

 

可以无密码登陆mysql

mysql -uroot -p

 

更改mysql 密码

 

 

 

添加新用户 （mysql 命令行下执行）

CREATE USER `admin`@`127.0.0.1` IDENTIFIED BY 'admin123';

 

GRANT `root`@`localhost` TO `admin`@`127.0.0.1`;

 

SET DEFAULT ROLE `root`@`localhost` TO `admin`@`127.0.0.1`;

 

GRANT `admin`@`127.0.0.1` TO `root`@`localhost`;
