第二、下载EPEL对应的版本和安装

版本寻找地址：http://fedoraproject.org/wiki/EPEL

我需要的是centos64位，我直接找到源后wget下载到当前目录：

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

然后进行安装：

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

第三、安装redis

yum install redis

然后我们再执行安装命令就可以正常的安装，期间会提到需要输入y回车我们就根据提示输入回车直到安装完毕。
