RHEL 6.6配置网易CentOS镜像的yum源小结

   之前没有使用过网易CentOS镜像的yum源，最近由于需要，遂在一台测试服务器验证、测试了一下如何配置使用网易的Cent0S的yum源。此文仅仅是笔记性质，参考了网上大量资料（文末“参考资料”的相关链接）。

1： 删除RHEL 6.6原有的YUM相关包

[root@mytestlnx03 ~]# rpm -qa | grep yum

yum-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-aliases-1.1.30-30.el6.noarch

PackageKit-yum-plugin-0.5.8-23.el6.x86_64

yum-utils-1.1.30-30.el6.noarch

yum-plugin-verify-1.1.30-30.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 --nodeps

warning: /etc/yum.conf saved as /etc/yum.conf.rpmsave

[root@mytestlnx03 ~]# rpm -qa | grep yum

[root@mytestlnx03 ~]# 

2：下载yum的相关安装包

 

 

注意：由于yum源一直在更新，所以有可能下面这些安装包已经不存在了（新的安装包给替换了），所以必须直接去网易的官方镜像验证确认，如果更新了，使用最新的安装包即可。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

网上有些资料还安装了其它yum相关包。这里测试发现这些包已经足够，当然测试也不充分，理解没有深入。仅仅是使用简单的功能

 

3：安装yum相关包以及依赖的包

[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

安装python-urlgrabber与原来的python中的组件冲突，如下所示，之前卸载yum相关组件时，没有卸载python-urlgrabber-3.9.1-9.el6.noarch

[root@mytestlnx03 tmp]# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm

warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

[root@mytestlnx03 tmp]# rpm -qa|grep python-url

python-urlgrabber-3.9.1-9.el6.noarch

[root@mytestlnx03 tmp]# rpm -e --nodeps python-urlgrabber-3.9.1-9.el6.noarch

[root@mytestlnx03 tmp]# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm

   3:yum                    ########################################### [100%]

4：修改yum的repo配置文件

删除原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 *

下载repo文件，放在 /etc/yum.repos.d/下面

[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：将baseurl中的$releasever修改为centos版本号，这里使用6替换，如下截图所示：

 

5：测试验证yum配置是否正确

 

[root@mytestlnx03 ~]# yum clean all

[root@mytestlnx03 ~]# yum list | grep ls
