Redhat Linux RHEL5配置CentOS YUM更新源

YUM是Redhat Linux在線安裝更新及軟件的工具，但是這是RHEL5的收費功能，如果沒有購買Redhat的服務時不能使用RHEL5的更新源的，會提示註冊。

由於CentOS是從Redhat演化而來的免費Linux版本，因此可以利用CentOS的yum更新源來實現RHEL5的YUM功能。配置方法如下：

檢查yum是否安裝，默認情況下都是安裝好的，總共4各包。

[root@linux-a ~]# rpm -qa |grep yum
yum-metadata-parser-1.0-8.fc6
yum-3.0.1-5.el5
yum-rhn-plugin-0.4.3-1.el5
yum-updatesd-3.0.1-5.el5

配置yum更新源

創建/etc/yum.repos.d/CentOS-Base.repo文件，定義yum更新源，這裏使用的是上海交大的CentOS更新源

[root@linux-a ~]# vi /etc/yum.repos.d/CentOS-Base.repo
