MySQL中添加用户,新建数据库,用户授权,删除用户,修改密码

授权 ：grant all privileges on *.* to test@'%' identified by "123456";

刷新授权：flush privileges;

取消授权：revoke all privileges on *.* FROM 'test'@'%';

重新授权: GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER ON *.* TO 'test'@'%';

如果报错：ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

可能登陆mysql方式有问题 不要用localhost登陆

改用：mysql -u -p -h 指定地址的方式进行登陆！

修改密码 ：set password for 'test'@'%' = password('123');

删除用户：drop user test;
