RHEL6.5 的yum不可用问题处理解决

说明：RHEL6.5 配置yum源后可以使用yum安装软件，但是只执行yum命令后提示如下错误信息

0.查看之前安装yum软件包
[root@dbserver ~]# rpm -qa |grep yum
yum-3.2.29-40.el6.noarch
PackageKit-yum-plugin-0.5.8-21.el6.x86_64
yum-utils-1.1.30-14.el6.noarch
yum-plugin-security-1.1.30-14.el6.noarch
PackageKit-yum-0.5.8-21.el6.x86_64
yum-rhn-plugin-0.9.1-48.el6.noarch
yum-metadata-parser-1.1.2-16.el6.x86_64
[root@dbserver ~]#

1.使用yum安装telnet软件
[root@dbserver ~]# yum install telnet
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager

2.单独执行yum命令
[root@dbserver ~]# yum
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
You need to give some command
