RedHat7安装网络yum源出现：Loaded plugins: product-id, refresh-packagekit, security ……的解决方法

        最近给虚拟机安装阿里的yum源的时候在执行yum makecache命令是报错：Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager This system is not reGIStered with an entitlement server. You can use subscription-manager to register. Http://mirrors.aliyun.com/Centos/7Server/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror.

        后来在网友的帮助下得以解决，在这里给大家复盘一下，顺便分享解决方案。

一、安装阿里yum源（问题复盘）

        1、备份原有yum源

mv /etc/yum.repos.d/redhat.repo   /etc/yum.repos.d/redhat.repo.backup

        2、下载新的阿里yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

        3、检查

         4、清缓存

        5、yum makecache(此处开始报错)

[root@192 yum.repos.d]# yum makecache
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.

二、问题解决

编辑CentOS-Base.repo文件，把文件里面的$releasever全部替换为版本号：7最后保存！

%s/$releasever/7/g 

如下图所示：

 接下来再次执行yum makecache即可
