下载 RPM 包

wget http://ftp.iij.ad.jp/pub/linux/centos-vault/6.8/cr/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://ftp.iij.ad.jp/pub/linux/centos-vault/6.8/cr/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm
wget http://ftp.iij.ad.jp/pub/linux/centos-vault/6.7/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://ftp.iij.ad.jp/pub/linux/centos-vault/6.7/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

安装

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

安装成功后，会有如下类似输出：

Preparing...                ########################################### [100%]
	package python-iniparse-0.3.1-2.1.el6.noarch is already installed

报错

上面下载安装包的时候多下载了一个python-urlgrabber，我这里的系统是已经安装了的。

[root@localhost yum]# rpm -qa|grep python-urlgrabber
python-urlgrabber-3.9.1-11.el6.noarch

如果报错说缺少这个包，或者是提示版本太旧，则重新装上我们刚才下载的那个即可。

# 卸载
rpm -qa|grep python-urlgrabber | rpm -e
# 安装
rpm -ivh python-urlgrabber-3.9.1-9.el6.noarch.rpm

我先前直接安装，系统就提示我版本冲突了。
