RedHat使用CentOS Yum源

RedHat yum源是收费的，没有成功注册RH的机器是不能正常使用yum的，因此配置CentOS的yum源。

# 1 卸载本地yum #

首先，需要移除系统注册相关软件

> ∘ 查看相关软件：rpm -qa | grep subscription-manager
> 
> ∘ 移除相关软件：yum remove subscription-manager

rpm -qa|grep yum　　\#查看本地yum

为了使用CentOS提供的yum源，需要删除系统自带的yum：

rpm -qa|grep yum|xargs rpm -e --nodeps　　\#卸载本地yum，不检查依赖性，卸载yum程序

# 2 下载centos yum 程序 #

wget http://mirrors.163.com/centos/6/os/x86\_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86\_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86\_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86\_64.rpm

注意，如果下载时找不到文件，就登录到： http://mirrors.163.com/centos/6/os/x86\_64/ 上查找相应的文件。然后再下载。

版本可能随着包的更新导致在这个地址上不一定存在，可输入http://mirrors.163.com/centos/6/os/x86\_64/Packages（CentOS6），这个页上面有具体包列表，查找python-iniparse的包，修改为正确的地址即可。

执行：

[root@localhost ~]# rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm
    warning: yum-3.2.29-73.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
    error: Failed dependencies:

    [root@localhost ~]# wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm

# 3 安装centos yum程序 #

[root@localhost ~]# rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm python-urlgrabber-3.9.1-11.el6.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
    warning: yum-3.2.29-73.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

查找问题，是python-urlgrabber引起的，要删除掉旧的包：

[root@localhost ~]# 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@localhost ~]# man rpm
    [root@localhost ~]# rpm -e python-urlgrabber-3.9.1-8.el6.noarch
    [root@localhost ~]# 
    [root@localhost ~]# rpm -qa | grep python-urlg
    [root@localhost ~]#

再安装

# 4 配置centos yum源 #

cd /etc/yum.repos.d/　　\#进入到yum配置文件目录

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo　　\#下载CentOS配置文件

vi CentOS6-Base-163.repo　　\#编辑配置文件

如果你系统没有配置环境变量 $releasever 和  $basearch，（可以命令echo查看有没有）

那么配置文件就把 $releasever 都 改成6或者i386（如下会贴出几大步骤的截图）

可以使用命令：sed -i "s/\\$releasever/6/"CentOS6-Base-163.repo

yum clean all　　\#清除yum缓存

yum makecache　　\#更新yum缓存

#  #

# 5 测试yum #
