在rhel上配置yum 源

记录在redhat 上配置yum 源的过程。

服务器 redhat 6.7 版本 ，redhat本身的yum源需要注册，于是切换为Centos 6的源，以下记录 切换的过程。

1 查看并卸载本机安装的yum 相关包

查看

[root@localhost 20200422]# rpm -qa | grep yum
yum-langpacks-0.4.2-7.el7.noarch
yum-plugin-fastestmirror-1.1.31-42.el7.noarch
yum-utils-1.1.31-42.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-3.4.3-154.el7.centos.noarch

卸载

[root@localhost 20200422]# rpm -qa | grep yum | xargs rpm -e --nodeps

2 到阿里云下载相关rpm包 https://mirrors.aliyun.com/centos/6/os/x86_64/Packages/

createrepo-0.9.9-28.el6.noarch.rpm
python-urlgrabber-3.9.1-11.el6.noarch.rpm
yum-3.2.29-81.el6.centos.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
yum-updateonboot-1.1.30-41.el6.noarch.rpm
yum-utils-1.1.30-41.el6.noarch.rpm

3 安装

• 先安装 python-urlgrabber-3.9.1-11.el6.noarch.rpm

[root@localhost yum_temp]# rpm -Uvh python-urlgrabber-3.9.1-11.el6.noarch.rpm

• 再安装其余的包

[root@localhost yum_temp]#rpm -ivh yum-*

4 切换源

使用 wget下载新的 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
修改CentOS-Base.repo文件中的$releasever全部替换为版本号7.
命令： %s/$releasever/6/g

或者

cd /etc/yum.repos.d/ 
mv redhat.repo redhat.repo.bak
mv rhel-source.repo rhel-source.repo.bak
vi /etc/yum.repos.d/CentOS-Base.repo
粘贴如下信息：
 
#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.
#
