bitsCN.com
首先要声明一下:一般情况下,修改MySQL密码,授权,是需要有mysql里的root权限的。
注:本操作是在WIN命令提示符下,phpMyAdmin同样适用。
用户:phplamp 用户数据库:phplampDB
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
如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器,并使用mypassword作为密码
GRANTALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITHGRANT OPTION;
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;bitsCN.com
