之前沒有使用過網易CentOS鏡像的yum源，最近由於需要，遂在一臺測試伺服器驗證、測試了一下如何配置使用網易的Cent0S的yum源。此文僅僅是筆記性質，參考了網上大量資料（文末“參考資料”的相關鏈接）。
1： 刪除RHEL 6.6原有的YUM相關包
[root@mytestlnx03 ~]# rpm -qa | grep yumyum-plugin-security-1.1.30-30.el6.noarch
kabi-yum-plugins-1.0-2.el6.noarch
PackageKit-yum-0.5.8-23.el6.x86_64
yum-plugin-downloadonly-1.1.30-30.el6.noarch
yum-rhn-plugin-0.9.1-50.el6.noarch
yum-plugin-changelog-1.1.30-30.el6.noarch
yum-plugin-versionlock-1.1.30-30.el6.noarch
yum-3.2.29-60.el6.noarch
yum-presto-0.6.2-1.el6.noarch

yum-plugin-tmprepo-1.1.30-30.el6.noarch
yum-metadata-parser-1.1.2-16.el6.x86_64
[root@mytestlnx03 ~]# rpm -qa | grep yum | xargs rpm -e --nodepswarning: /etc/yum.conf saved as /etc/yum.conf.rpmsave
[root@mytestlnx03 ~]# rpm -qa | grep yum[root@mytestlnx03 ~]#
2：下載yum的相關安裝包
註意：由於yum源一直在更新，所以有可能下麵這些安裝包已經不存在了（新的安裝包給替換了），所以必須直接去網易的官方鏡像驗證確認，如果更新了，使用最新的安裝包即可。http://mirrors.163.com/centos/6/os/x86_64/Packages/
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
網上有些資料還安裝了其它yum相關包。這裡測試發現這些包已經足夠，當然測試也不充分，理解沒有深入。僅僅是使用簡單的功能
3：安裝yum相關包以及依賴的包
[root@mytestlnx03 tmp]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm warning: python-iniparse-0.3.1-2.1.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY
Preparing... ########################################### [100%]package python-iniparse-0.3.1-2.1.el6.noarch is already installed
安裝python-urlgrabber與原來的python中的組件衝突，如下所示，之前卸載yum相關組件時，沒有卸載python-urlgrabber-3.9.1-9.el6.noarch
[root@mytestlnx03 tmp]# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpmwarning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

4：修改yum的repo配置文件
刪除原yum的配置文件
[root@mytestlnx03 tmp]# cd /etc/yum.repos.d/[root@mytestlnx03 yum.repos.d]# ls backup redhat.repo rhel-source.repo server.repo
[root@mytestlnx03 yum.repos.d]# rm -rf *
下載repo文件，放在 /etc/yum.repos.d/下麵
[root@mytestlnx03 yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo--2019-07-22 14:11:02-- http://mirrors.163.com/.help/CentOS6-Base-163.repo

[root@mytestlnx03 yum.repos.d]#
修改配置文件CentOS6-Base-163.repo：將baseurl中的$releasever修改為centos版本號，這裡使用6替換，如下截圖所示：
5：測試驗證yum配置是否正確
[root@mytestlnx03 ~]# yum clean all
[root@mytestlnx03 ~]# yum list | grep ls
