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.c

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://@H_422_49@mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm

wget http://@H_422_49@mirrors.163.com/centos/6/os/x86_64/Packages/yum-Metadata-parser-1.1.2-16.el6.x86_64.rpm

wget http://@H_422_49@mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

wget http://@H_422_49@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@H_618_91@.el6.noarch.rpm

rpm -ivh yum-Metadata-parser-1.1.2-16@H_618_91@.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@L_673_11@：

1 [[email protected] test]# rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41@H_618_91@.el6.noarch.rpm 
2 warning: yum-3.2.29-81.el6.centos.noarch.rpm: Header V3 RSA/@H_618_91@SHA1 Signature,key ID c105b9de: NOKEY
3 @H_618_91@error: Failed dependencies:
4     python-urlgrabber >= 3.9.1-10 is needed by yum-3.2.29-81.el6.centos.noarch

@L_673_11@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://@H_422_49@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 [[email protected] test]# rpm -ivh python-urlgrabber-3.9.1-11@H_618_91@.el6.noarch.rpm 
2 warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/@H_618_91@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 [[email protected] test]# rpm -ivh --force python-urlgrabber-3.9.1-11@H_618_91@.el6.noarch.rpm 
2 warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/@H_618_91@SHA1 Signature,key ID c105b9de: NOKEY

最后执行第三条安装命令成功：

1 [[email protected] test]# rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41@H_618_91@.el6.noarch.rpm
