GRANT SELECT, INSERT ON test.user TO 'javacui'@'%';
GRANT ALL ON *.* TO 'javacui'@'%';
注意:用以上命令授权的用户不能给其它用户授权,如果想让该用户可以授权,用以下命令
?
1
GRANT privileges ON databasename.tablename TO 'username'@'host' WITH GRANT OPTION;
设置与更改用户密码
?
1
SET PASSWORD FOR 'username'@'host' = PASSWORD('newpassword');
如果是当前登陆用户用
?
1
SET PASSWORD = PASSWORD("newpassword");
撤销用户权限
?
1
REVOKE privilege ON databasename.tablename FROM 'username'@'host';
说明: privilege, databasename, tablename – 同授权部分
例子
?
1
REVOKE SELECT ON *.* FROM 'javacui'@'%';
注意:
假如你在给用户’javacui’@'%’授权的时候是这样的(或类似 的):GRANT SELECT ON test.user TO ‘javacui’@'%’, 则在使用 REVOKE SELECT ON *.* FROM ‘javacui’@'%’;命令并不能撤销该用户对test数据库中user表的SELECT 操作
相反,如果授权使用的是GRANT SELECT ON *.* TO ‘javacui’@'%’;则 REVOKE SELECT ON test.user FROM ‘javacui’@'%’;命令也不能撤销该用户对test数据库中user表的 Select 权限
具体信息可以用命令SHOW GRANTS FOR ‘javacui’@'%’; 查看
删除用户
?
1
DROP USER ‘username’@'host’;
操作后切记刷新数据库
?
1
flush privileges;
