RedHat 7 使用Centos7 的yum源

轉自Richard的blog，並簡要編輯

思路：卸載redhat自帶yum，而後下載centos的yum，安裝後修改配置文件

 

1、首先到http://mirrors.163.com/centos下載軟件包

 

x86 地址：http://mirrors.163.com/centos/7/os/i386/Packages/

x86_64 地址：http://mirrors.163.com/centos/7/os/x86_64/Packages/

必要下載的軟件包有（以64位系統爲例）：

a  python-iniparse-0.3.1-2.1.el6.noarch.rpm

b  yum-3.2.29-40.el6.centos.noarch.rpm

c  yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

d  yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

下載命令：

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

[注] :版本不必定要最新的

 

2、卸載RedHat自帶的yum

 

      rpm -qa | grep yum | xargs rpm -e --nodeps

      注：

a、xargs是一條Unix和類Unix操做系統的經常使用命令。它的做用是將參數列表轉換成小塊分段傳遞給其餘命令，以免參數列表過長的問題

b、--nodeps  強制卸載,無論依賴性

 

3、安裝下載的centos的yum包：

 

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm

rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

 

[注] :最後2個須要一塊兒安裝，不然會出現依賴性錯誤

 

4、到http://mirrors.163.com的 centos幫助文檔 中下載CentOS7-Base-163.repo文件，存放到/etc/yum.repos.d中

 

wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

 

5、編輯CentOS7-Base-163.repo文件，

    將其中的$releasever更改成centos的版本號，這裏修改成7

# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.  You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # #   [base] name=CentOS-7 - Base - 163.com baseurl=http://mirrors.163.com/centos/7/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-7   #released updates [updates] name=CentOS-7 - Updates - 163.com baseurl=http://mirrors.163.com/centos/7/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-7   #additional packages that may be useful [extras] name=CentOS-7 - Extras - 163.com baseurl=http://mirrors.163.com/centos/7/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-7   #additional packages that extend functionality of existing packages [centosplus] name=CentOS-7 - Plus - 163.com baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6   #contrib - packages by Centos Users [contrib] name=CentOS-7 - Contrib - 163.com baseurl=http://mirrors.163.com/centos/7/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-7

 

6、yum clean all 清除原有緩存

7、yum makecache  獲取yum列表

出現下面提示，表示yum更改完成：
