Last modified:

创建用户

CREATE USER "newuser"@"%" IDENTIFIED BY "password";

授权所有权限

GRANT ALL PRIVILEGES ON *.* TO "newuser"@"%";

其中的 % 代表这个用户可以在任意主机登录。

如果只需要在本机登录,使用 localhost

显示一个用户的当前授权:

SHOW GRANTS FOR newuser

更改用户密码:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'yourpasswd';
flush privileges;

其他问题

EXPLAIN, slow-log
