RedHat 7 使用Centos7 的yum源

思路:卸载redhat自带yum,然后下载centos的yum,安装后修改配置文件

 

1、首先到http://mirrors.163.com/centos下载软件包

 

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/

必要下载的软件包有(以64位系统为例):

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

下载命令:

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] :版本不一定要最新的

 

2、卸载RedHat自带的yum

 

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

      注:

a、xargs是一条Unix和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令,以避免参数列表过长的问题

b、--nodeps  强制卸载,不管依赖性

 

3、安装下载的centosyum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] :最后2个需要一起安装,否则会出现依赖性错误

 

4、到http://mirrors.163.com centos帮助文档 中下载CentOS7-Base-163.repo文件,存放到/etc/yum.repos.d

 

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

 

5、编辑CentOS7-Base-163.repo文件,

    将其中的$releasever更改为centos的版本号,这里修改为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.

#

6yum clean all 清除原有缓存

7yum makecache  获取yum列表

出现下面提示,表示yum更改完成:
