  • Redhat更换yum源

    redhat 默认自带的 yum 源需要注册，才能更新，所以对于我们来说需要替换掉redhat的yum源。下文更换为网易的。

    删除原有的yum

    rpm -qa|grep yum|xargs rpm -e --nodeps

    下载yum安装文件

    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-iniparse-0.3.1-2.1.el6.noarch.rpm

    [注] 下载时可能会找不到文件，登录http://mirrors.163.com/centos/6/os/x86_64/ 更换相应的文件。

    安装

    rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm

rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

    [注] 最后两个包需要同时安装，因为存在相互依赖

    然而在执行最后一个安装命令时，出现了如下错误：

    1 [root@root test]# rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm 
2 warning: yum-3.2.29-81.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
3 error: Failed dependencies:
4     python-urlgrabber >= 3.9.1-10 is needed by yum-3.2.29-81.el6.centos.noarch

    错误原因是缺少了3.9.1-10及以上版本的python-urlgrabber的依赖，所以从http://mirrors.163.com/centos/6/os/x86_64/ 寻找所需要的包。

    wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm

    然后安装时又出错了：

    1 [root@root test]# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm 
2 warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

    与历史版本冲突了，在rpm安装的命令中加入--force 强制安装成功：

    1 [root@root test]# rpm -ivh --force python-urlgrabber-3.9.1-11.el6.noarch.rpm 
2 warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
3 Preparing...                ########################################### [100%]
4    1:python-urlgrabber      ########################################### [100%]

    最后执行第三条安装命令成功：

    1 [root@root test]# rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm 
2 warning: yum-3.2.29-81.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

4    1:yum-plugin-fastestmirro########################################### [ 50%]
5    2:yum                    ########################################### [100%]

    更换yum源

    mv /etc/yum.repos.d/rhel-source.repo /etc/yum.repos.d/rhel-source.repo.bak
 
vim /etc/yum.repos.d/rhel-debuginfo.repo

    yum clean all 命令清除原有缓存，就成功了。
