Redhat 6 ：This system is not registered to Red Hat Subscription Management

[johnnian]

现象

在RadHat 6.5 上使用yum命令的时候，发现提示：

[root@5093f2bb61ba /]# yum groupinstall 'Development Tools' -y
Loaded plugins: ovl, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
Setting up Group Process
Warning: Group Development Tools does not exist.
Error: No packages in any requested group available to install or update

这个原因是：Redhat的yum是要注册收费的，所以，直接替换成CentOS的～

解决步骤

步骤1: 卸载自带的yum

[root@5093f2bb61ba /]# rpm -qa|grep yum
yum-3.2.29-81.el6.noarch
yum-plugin-ovl-1.1.30-42.el6_10.noarch
yum-metadata-parser-1.1.2-16.el6.x86_64
yum-utils-1.1.30-42.el6_10.noarch
[root@5093f2bb61ba /]# rpm -qa|grep yum|xargs rpm -e --nodeps
warning: /etc/yum.conf saved as /etc/yum.conf.rpmsave
[root@5093f2bb61ba /]# rpm -qa|grep yum

步骤2: 安装CentOS yum

[root@5093f2bb61ba /]# rpm -ivh http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

[root@5093f2bb61ba /]# rpm -ivh  http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm  http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
