RHEL7.2搭建yum源
我在RHEL7.2搭建本地yum时发现突然报错了。
查看了一下报错信息显示
加载插件：langpacks，产品ID，搜索禁用回购，订阅管理器该系统未注册到红帽订阅管。你可以使用subscription-m急于注册.repolist：0由于Redhat的yum在线更新是收费的，如果没有注册的话是不能使用的，即不能在线安装软件。
我只好用CentOS的yum来替换掉
1.先检查一下yum的RPM包组
在用RPM依次强制删除
rpm -e yum-rhn-plugin-2.0.1-5.el7.noarch –nodeps
rpm -e yum-3.4.3-132.el7.noarch –nodeps
rpm -e yum-utils-1.1.31-34.el7.noarch –nodeps
rpm -e yum-langpacks-0.4.2-4.el7.noarch –nodeps
warning: /etc/yum/pluginconf.d/langpacks.conf saved as /etc/yum/pluginconf.d/langpacks.conf.
rpmsave（忽略这条信息）
rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 –nodeps
rpm -e PackageKit-yum-1.0.7-5.el7.x86_64 –nodeps
在检查一下yum包组
用centos相关包组替换掉RHEL的yum(下载时有可能包组更新，后缀不一样导致下载失败，解决方法：用浏览器进入下载路径手动下载，如果有centos7.2的ISO可以解压后再Packages下找到这些包，um-rhn-plugin-2.0.1-9.el7.noarch.rpm这个包要在rhel下找)
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-rhn-plugin-2.0.1-9.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-154.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-42.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-langpacks-0.4.2-7.el7.noarch.rpm
RPM执行安装安装yum（按照以下顺序）
rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm 依赖于yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm
下载该安装包并且与yum-3.4.3-132.el7.centos.0.1.noarch.rpm一起安装
rpm -ivh yum-3.4.3-132.el7.centos.0.1.noarch.rpm yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm
rpm -ivh yum-rhn-plugin-2.0.1-5.el7.noarch.rpm(忽略警告)
rpm -ivh yum-utils-1.1.31-34.el7.noarch.rpm(忽略警告)
rpm -ivh yum-langpacks-0.4.2-4.el7.noarch.rpm(忽略警告)
rpm -ivh PackageKit-yum-1.0.7-5.el7.centos.x86_64.rpm(忽略警告)
有依赖关系下载PackageKit-glib-1.0.7-5.el7.centos.x86_64.rpm(忽略警告)
rpm -ivh PackageKit-glib-1.0.7-5.el7.centos.x86_64.rpm(忽略警告)
rpm -ivh PackageKit-1.0.7-5.el7.centos.x86_64.rpm(忽略警告)
rpm -i –force –nodeps PackageKit-1.0.7-5.el7.centos.x86_64.rpm(忽略警告)
rpm -ivh PackageKit-yum-1.0.7-5.el7.centos.x86_64.rpm(忽略警告)
新建一个网络yum源
vim /etc/yum.repos.d/CentOS-Base.repo
[base]
name=CentOS-$releasever – Base – 163.com

测试一下并且修正错误
yum install vim
yum update
解决之前遗留问题
rpm -e PackageKit-1.0.7-5.el7.centos.x86_64 –nodeps
yum install PackageKit-1.0.7-5.el7.centos.x86_64.rpm
在用yum update不会报错，安装完毕
