mysql 用戶建立、受權及刪除、取消權限操做

刪除、取消權限操做：

1. drop user 'user_name'@'%';

2. drop user 'user_name'@'localhost'

3. flush privileges; //從新加載受權表

注意：delete from user where user='user_name'；直接操做mysql.user表不行，重建同名用戶時會出現「operation CREATE USER failed」錯誤提示信息

 

添加用戶、受權操做

1. create USER ’user_name' identified by 'password'; //建立用戶名和密碼

2. grant ALL ON 'db_name'.'tb_name' TO 'user_name'@'%' identified by 'password' //給 ‘user_name’@'%'受權

3. grant ALL ON 'db_name'.'tb_name' TO 'user_name'@'localhost' identified by 'password' //給 'user_name'@'localhost'受權

4. flush privileges; //從新加載受權表
