redhat 的更新包只對注冊的用戶生效，所以我們自己手動更改成CentOS 的更新包，CentOS幾乎和redhat是一樣的，所以無需擔心軟件包是否可安裝，安裝之后是否有問題。
1、首先刪除redhat原有的yum ，因為redhat 原本的yum 沒有注冊為redhat用戶是用不了的。
rpm -aq|grep yum|xargs rpm -e --nodeps rpm -aq|grep python-iniparse|xargs rpm -e --nodeps
2、下載163的yum 安裝包
# wget http://mirrors.163.com/centos/7.2.1511/os/x86_64/Packages/yum-3.4.3-132.el7.centos.0.1.noarch.rpm # wget http://mirrors.163.com/centos/7.2.1511/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm # wget http://mirrors.163.com/centos/7.2.1511/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm # wget http://mirrors.163.com/centos/7.2.1511/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm
3、安裝下載的rpm包
rpm -ivh *.rpm- 1
4、創建文件/etc/yum.repos.d/rhel-debuginfo.repo並寫入
[base]
name=CentOS-$releasever - Base baseurl=http://mirrors.163.com/centos/7.2.1511/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.2.1511/os/x86_64/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.163.com/centos/7.2.1511/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.2.1511/os/x86_64/RPM-GPG-KEY-CentOS-7 [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.163.com/centos/7.2.1511/extras//$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.2.1511/os/x86_64/RPM-GPG-KEY-CentOS-7 [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.163.com/centos/7.2.1511/centosplus//$basearch/ gpgcheck=1 enabled=0
6、 yum clean all
7、 yum update 測試。
8、 安裝 epel 源
# yum install epel-release
