centos6.3下yum安装redis

我得是centos 6.3，如果直接用yum安装redis，报错，如下：

[root@CentOS6 etc]# yum install redis

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

Setting up Install Process

No package redis available.

Error: Nothing to do

实际上redia位于第三方的yum源里面，不在centos官方yum源里面，如何解决呢？

1：去下面的网站下载EPEL对应的版本：（epel是fedora维护的yum源，里面软件众多）

http://fedoraproject.org/wiki/EPEL

2：我下载的是这个：

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

3：安装epel：

rpm -ivh epel-release-6-8.noarch.rpm

warning: epel-release-6-8.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEY

4：安装redis：

[root@CentOS6 ~]# yum install redis

Is this ok [y/N]:y

然后再装php-redis扩展

yum install php-redis

重启service httpd restart就可以了。

    <?php  
    $redis = new Redis();  
    $redis->connect('127.0.0.1',6379);  
    $redis->set('test','hello world!');  
    echo $redis->get('test');  
    ?>
