mysql远程连数据之经验总结（蛇年博客第一问，来自上海大雪的亲切问候）

1. 新增用户

mysql>insert into mysql.user(Host,User,Password) values("localhost","lionbule",password("hello1234"));
mysql>flush privileges;

2. 修改用户密码

mysql>update mysql.user set password=password('new password') where User="lionbule" and Host="localhost";
mysql>flush privileges;

3. 删除用户

mysql>DELETE FROM user WHERE User="lionbule" and Host="localhost";
mysql>flush privileges;

4. 权限分配

4.1. grant用法

grant 权限 on 数据库.* to 用户名@'登录主机' identified by '密码'

权限：  
    常用总结, ALL/ALTER/CREATE/DROP/SELECT/UPDATE/DELETE  
数据库：  
     *.*                    表示所有库的所有表  
     test.*                表示test库的所有表  
     test.test_table  表示test库的test_table表       
用户名：  
     mysql账户名  
登陆主机：  
     允许登陆mysql server的客户端ip  
     '%'表示所有ip  
     'localhost' 表示本机  
     '192.168.10.2' 特定IP  
密码：  
      账户对应的登陆密码

举例如下：

mysql>grant all  on test.* to lionbule@'%' identified by 'hello1234';
mysql>flush privileges;

php测试一番

<?php
mysql_connect("192.168.1.101", "root", "") or die("Could not connect: " . mysql_error());
?>

D:\xampp\mysql\bin\mysql -h192.192.192.230 -uuserTest -p;
