centos6.3 使用yum方式安裝redis

我得是centos 6.3，如果直接用yum安裝redis，報錯，如下：

[root@localhost ~]# yum install redis
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.btte.net
* extras: mirrors.btte.net
* updates: mirrors.btte.net
base                                                     | 3.7 kB     00:00     
extras                                                   | 3.5 kB     00:00     
updates                                                  | 3.5 kB     00:00     
updates/primary_db                                       | 4.6 MB     00:25     
Setting up Install Process
No package redis available.
Error: Nothing to do

實際上redia位於第三方的yum源裏面，不在centos官方yum源裏面，如何解決呢？


1：去下面的網站下載EPEL對應的版本：（epel是fedora維護的yum源，裏面軟件衆多）
http://fedoraproject.org/wiki/EPEL
2：我下載的是這個：

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

3：安裝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
Preparing...                ########################################### [100%]
1:epel-release           ########################################### [100%]

4.安裝redis 安裝方法如下：

[root@localhost ~]# yum install redis
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * atomic: mirrors.neusoft.edu.cn
 * base: mirror.bit.edu.cn
 * extras: mirror.bit.edu.cn
 * updates: mirrors.btte.net

然後再使用

[root@localhost ~]# redis-cli 
redis 127.0.0.1:6379> 

現在可以存東西了。

redis 127.0.0.1:6379> set name chinese
OK
redis 127.0.0.1:6379> get name
"chinese"
redis 127.0.0.1:6379>
