关于redhat 6.5 yum源配置问题的解决方法

redhat6.5在安装好命令界面后执行yum list或yum update命令提示：This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. 主要是未订阅注册redhat。导致yum源不可使用。解决方法可以将现有系统上的yum软件卸载之后，安装上CentOS6.5的yum软件，然后更改/etc/yum.repos.d/目录下的CentOS配置文件，将yum源更改为163的源，这样就可以正常使用redhat6.5的yum命令了。

安装好redhat6.5后，执行yum list会跳出未注册信息。这时我们用

rpm -qa | grep yum

命令查看已安装的yum相关软件。此时会显示已安装的yum相关软件有4款。

接着执行

rpm -qa | grep yum | xargs rm -e --nodeps

将这四款软件卸载

接着将CentOS中的三款yum软件用winSCP火FTP工具上传到linux系统某一文件夹下，记住，要在root权限下。

yum-3.2.29-40.el6.centos.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.i686.rpm
yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

下载地址：CentOS6.5 yum安装包

winSCP或FTP传输工具网站上可以随意下载，这里就不多赘述。

接着在当前文件夹下执行：

rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

（如果这行命令执行失败，可能是之前的卸载命令没有执行成功，重新执行一次就可以）

安装成功后进入/etc/yum.repos.d/目录下（最好将已经存在的文件mv成.bak文件，如果不执行此操作也不会有问题）

# cd /etc/yum.repos.d/
# wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo # vi CentOS6-Base-163.repo

将CentOS6-Base-163.repo中的内容全部删除，将下面的代码粘贴进去，保存退出即可：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

最后执行 yum update即可。

这时候再试试 yum list是不是可以正常显示了~！
