解決redhat6.4的yum未註冊無法使用的問題
1.解除安裝redhat的yum，用指令rpm -qa|grep python-in|xargs rpm -e --nodeps
2.下載centos的yum，一共四個rpm。python-iniparse-0.3.1-2.1.el6.noarch.rpm。yum-3.2.29-73.el6.centos.noarch.rpm。yum-metadata-parser-1.1.2-16.el6.x86_64.rpm。yum-plugin-fastestmirror-1.1.31-505.fc22.noarch.rpm。
可以在這裡面下載:http://rpmfind.net/linux/rpm2html/search.php?query=yum&submit=Search+...&system=&arch=
3.四個包一起安裝rpm -ivh yum-* python-urlgrabber-3.9.1-11.el6.noarch.rpm
4.新增/etc/yum.repos.d/CentOS-Base.repo,內容如下
