php 连接mysql问题

Jun 06, 2016 pm 08:20 PM
mysql php

问题背景的:

我本地机器记做:local
内网服务器机器多台:server_a server_b
个人外网机器:net
现在 local server_a server_b net 上面都有mysql 和php

问题现象是这样子的

php 代码是最简单的mysql_connect 连接数据库,代码一样

<code># -> :标示请求数据, =》:标示结果
local php    -> local mysql    =>ok
local php    -> server_a mysql =>error
local php    -> net mysql      =>ok
server_a php -> server_a mysql =>ok
server_b php -> server_a mysql =>ok</code>
Copy after login
Copy after login

为什么local php 连接server_a 会出问题。
数据库配置和php代码完全一样
求大神指点下可能原因

你的 local 服务有没有和 server 处于一个网路下,如果不在一个网络那就不谈能不能访问了。
如果在一个网络,或者直接有外部端口衔接,那你注意检查一下 server 里的 mysql 有没有开启外部访问的权限。
