1，下载最新的yum-3.2.28.tar.gz并解压</p>

<p>
wget <font color="#0044aa">http://yum.baseurl.org/download/3.2/yum-3.2.28.tar.gz</font><br>
tar xvf yum-3.2.28.tar.gz</p>

2，进入目录，运行安装</p>

<p>
cd yum-3.2.28<br>
yummain.py install yum</p>

<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
结果提示错误： CRITICAL:yum.cli:Config Error: Error accessing file for config file:///etc/</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
后来经猫哥提醒，原来是缺少配置文件。在etc目录下面新建yum.conf文件，然后再次运行 yummain.py install yum，顺利完成安装。</p>
