1.新建用户。
//登录MYSQL
@>mysql -u root -p
@>密码
//创建用户
mysql> insert into mysql.user(Host,User,Password) values("localhost","phplamp",password("1234"));
//刷新系统权限表
mysql>flush privileges;
这样就创建了一个名为:phplamp 密码为:1234 的用户。
然后登录一下。
mysql>exit;
@>mysql -u phplamp -p
@>输入密码
mysql>登录成功
2.为用户授权。
//登录MYSQL(有ROOT权限)。我里我以ROOT身份登录.
@>mysql -u root -p
@>密码
//首先为用户创建一个数据库(phplampDB)
mysql>create database phplampDB;
//授权phplamp用户拥有phplamp数据库的所有权限。
>grant all privileges on phplampDB.* to phplamp@localhost identified by '1234';
//刷新系统权限表
mysql>flush privileges;
mysql>其它操作
/*
如果想指定部分权限给一用户,可以这样来写:
mysql>grant select,update on phplampDB.* to phplamp@localhost identified by '1234';
//刷新系统权限表。
mysql>flush privileges;
*/
3.删除用户。
@>mysql -u root -p
@>密码
mysql>DELETE FROM user WHERE User="phplamp" and Host="localhost";
mysql>flush privileges;
//删除用户的数据库
mysql>drop database phplampDB;
4.修改指定用户密码。
@>mysql -u root -p
@>密码
mysql>update mysql.user set password=password('新密码') where User="phplamp" and Host="localhost";
mysql>flush privileges;
