Redis server went away与selinux

代码：

<?php
ini_set('display_errors','On');
error_reporting(E_ALL);
$obj = new Redis();
$rs =  $obj->connect('127.0.0.1', 6379, 20);
$obj->set('test','hello andy');
echo $obj->get('test');

apache浏览器端（我一开始没意识到浏览器端和shell端的区别，我是后来有人提到seliunx的问题才发现的）运行报错如下：

Fatal error: Uncaught exception 'RedisException' with message 'Redis server went away' in /var/www/html/test.php:7 Stack trace: #0 /var/www/html/test.php(7): Redis->set('test', 'hello andy') #1 {main} thrown in /var/www/html/test.php on line 7

客户端shell运行正常：

[dev@LAMP1 html]$ php test.php
hello andy[dev@LAMP1 html]$ 

谢谢这位博客提供的资料：
