创建用户并分配权限；

复制代码 代码如下:

insert into mysql.user(Host,User,Password) values("localhost","phplamp",password("1234"));//创建用户

grant all privileges on dbname.* to 'username'@'%' identified by 'password';//创建用户并分配所有权限

grant select,update on phplampDB.* to phplamp@localhost identified by '1234';//创建用户并分配权限

update mysql.user set password=password('新密码') where User="phplamp" and Host="localhost";//修改用户密码

--删除用户指定权限

revoke insert,update,delete,select ON *.* from 'xbb'@'localhost' IDENTIFIED BY '123';
