redhat 的更新包只對註冊的用戶生效，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，安裝之後是否有問題。

1、首先刪除redhat原有的yum ，因爲redhat 原本的yum 沒有註冊爲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

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
