RedHat 7 使用Centos7 的yum源

思路：解除安裝redhat自帶yum，然後下載下傳centos的yum，安裝後修改配置檔案

必要下載下傳的軟體包有（以64位系統為例）：

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

下載下傳指令：

[注] :版本不一定要最新的

2、解除安裝RedHat自帶的yum

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

      注：

b、--nodeps  強制解除安裝,不管依賴性

3、安裝下載下傳的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個需要一起安裝，否則會出現依賴性錯誤

5、編輯CentOS7-Base-163.repo檔案，

    将其中的$releasever更改為centos的版本号，這裡修改為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

gpgcheck=1

#released updates

[updates]

name=CentOS-7 - Updates - 163.com

#additional packages that may be useful

[extras]

name=CentOS-7 - Extras - 163.com

#additional packages that extend functionality of existing packages

[centosplus]

name=CentOS-7 - Plus - 163.com

enabled=0

#contrib - packages by Centos Users

[contrib]

name=CentOS-7 - Contrib - 163.com

6、yum clean all 清除原有緩存

7、yum makecache  擷取yum清單

出現下面提示，表示yum更改完成：
