设置步骤

![Red Hat Linux安装CentOS的yum源Red Hat Linux安装CentOS的yum源][Red Hat Linux_CentOS_yum_Red Hat Linux_CentOS_yum]

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

![Red Hat Linux安装CentOS的yum源Red Hat Linux安装CentOS的yum源][Red Hat Linux_CentOS_yum_Red Hat Linux_CentOS_yum 1]

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

    libpython2.6.so.1.0()(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.  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.

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。
