RHEL 6以上操作系统Yum提示This system is not registered
一、问题现象：

Loaded plugins: product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
Error: clean requires an option: headers, packages, metadata, dbcache, plugins, expire-cache, rpmdb, all
[root@open_source ~]# yum check-update
Loaded plugins: product-id, search-disabled-repos, subscription-manager

二、问题原因：
因为我的操作系统使用的是RedHat，提示需要注册订阅，说白了就是要掏钱才给用。
三、问题分析：
该问题的处理办法实际上很简单，因为RedHat是商业版企业Linxu系统，其涉及到的包只有Yum，我们可以通过替换社区版的包解决此问题。
四、解决办法：
替换社区版CentOS的包解决此问题。
4.1. 获取包的途径主要有以下几个：
http://mirror.centos.org/
https://mirrors.edge.kernel.org/
http://mirrors.aliyun.com/centos/
<1span style="font-family:"&color:#4EA1DB;text-underline:none">http://mirrors.sohu.com
……
4.2. 我通过Centos Yum站点下载以下四个所需的包
http://mirror.centos.org/centos-7/7.7.1908/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
http://mirror.centos.org/centos-7/7.7.1908/os/x86_64/Packages/python-urlgrabber-3.10-9.el7.noarch.rpm
http://mirror.centos.org/centos-7/7.7.1908/os/x86_64/Packages/yum-3.4.3-163.el7.centos.noarch.rpm
http://mirror.centos.org/centos-7/7.7.1908/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
http://mirror.centos.org/centos-7/7.7.1908/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-52.el7.noarch.rpm
注意：下载的包要大于或等于当前系统版本，下载之前要确认操作系统版本，可通过命令cat /etc/redhat-release 查看。
4.3 卸载系统中现有的yum包
[root@open_source ~]# rpm -qa|grep yumyum-metadata-parser-1.1.4-10.el7.x86_64yum-3.4.3-163.el7.noarchyum-rhn-plugin-2.0.1-10.el7.noarch[root@open_source ~]# rpm -qa|grep yum | xargs rpm -e --nodeps[root@open_source ~]# rpm -qa|grep yum[root@open_source ~]#
4.4 分别安装刚才下载的几个RPM包
