Red Hat Linux安装CentOS的yum源

来源：博客园
RedHat凭借其卓越的稳定性和强大的服务占领着企业linux大部分市场，系统本身免费，但是其服务却是收费的，例如其软件包管理服务yum。不想出钱那就自己配置yum源就好了，因为yum在线更新是收费的，未注册则不能使用，这个是要填序列号激活的，解决办法是更换为CentOS的yum。
设置步骤

1. 查询原有的yum

[root@orcl ~]# rpm -qa |grep yum yum-plugin-fastestmirror-1.1.30-37.el6.noarch yum-metadata-parser-1.1.2-16.el6.i686 yum-utils-1.1.30-37.el6.noarch yum-plugin-security-1.1.30-37.el6.noarch yum-3.2.29-75.el6.centos.noarch yum-rhn-plugin-0.9.1-43.el6.noarch

2. 删除原有的yum

[root@orcl ~]# rpm -aq|grep yum|xargs rpm -e –-nodeps [root@orcl ~]# rpm -qa |grep yum [root@orcl ~]#

3. 查询原有yum配置

[root@orcl ~]# whereis yum yum: /etc/yum [root@orcl ~]# rm -fr /etc/yum

4. 下载需要的安装包http://mirrors.163.com/centos/6.8/os/i386/Packages/系统为32的，所以我选择i386。64的自行查找x86_64。可以使用

wget http://mirrors.163.com/centos/6.8/os/i386/Packages/yum-3.2.29-73.el6.centos.noarch.rpm

下载

yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm yum-metadata-parser-1.1.2-16.el6.i686.rpm Python-iniparse-0.3.1-2.1.el6.noarch.rpm

5. 安装python

[root@orcl ~]# rpm -ivh python-iniparse-….noarch.rpm warning: python-iniparse-0.4-9.el7.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY error: Failed dependencies: python(abi) = 2.7 is needed by python-iniparse-0.4-9.el7.noarch

当前安装版本与服务器不兼容，退后一个版本再试。查看当前发行版本号

cat /etc/issue
遇到的错误

系统位数与安装程序包位数不一致 file /bin/ls

error: Failed dependencies: libc.so.6()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64 libc.so.6(GLIBC_2.2.5)(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64 libglib-2.0.so.0()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64 libpthread.so.0()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64 libpython2.6.so.1.0()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64 libsqlite3.so.0()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64 libxml2.so.2()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64 libxml2.so.2(LIBXML2_2.4.30)(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64
重新下载32位程序包
[root@orcl ~]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm Preparing… ########################################### [100%] package python-iniparse-0.3.1-2.1.el6.noarch is already installed [root@orcl ~]# rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm Preparing… ########################################### [100%] 1:yum-metadata-parser ########################################### [100%] [root@orcl ~]# rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm Preparing… ########################################### [100%] 1:yum-plugin-fastestmirro########################################### [ 50%] 2:yum ########################################### [100%] [root@orcl ~]#

注意最后两个包必需同时安装，否则会相互依赖更改yum源（使用网易的CentOS镜像源）

[root@localhost yum]# cd /etc/yum.repos.d/ [root@localhost yum.repos.d]# rm -rf * [root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo [root@localhost yum.repos.d]# vi CentOS6-Base-163.repo

将所有 $releasever 修改为具体的版本号，我这里写的是6.8，这个自己打开（http://mirrors.163.com/centos）找一下就可以。

# 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.

清理yum缓存

yum clean all

显示已安程序包及可安程序包

yum list

可以按要求更新程序包或安装

yum update / yum install 包名

到此结束了，亲们
