rhel替换centosyum源

Posted 2020-09-26

由于rhel需要注册才能使用yum源，所以会更换成centos源。

接下来就用rhce的系统，安装centos源。

需要包的地址：http://mirrors.163.com/centos/7/os/x86_64/Packages/

1.安装wget：

1 [[email protected] centosyum]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/wget-1.14-13.el7.x86_64.rpm
2 
3 [[email protected] centosyum]# rpm -ivh wget-1.14-13.el7.x86_64.rpm

2.卸载yum：

1 [[email protected] centosyum]# rpm -qa | grep yum | xargs rpm -e --nodeps
2 warning: /etc/yum/pluginconf.d/langpacks.conf saved as /etc/yum/pluginconf.d/langpacks.conf.rpmsave
3 [[email protected] centosyum]# rpm -qa yum

3.下载centos的yum安装包：

1 [[email protected] centosyum]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
2 [[email protected] centosyum]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-150.el7.centos.noarch.rpm
3 [[email protected] centosyum]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
4 [[email protected] centosyum]# wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm

4.安装包：最后两个一起装，因为会检测依赖性。

1 [[email protected] centosyum]# rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm 
2 [[email protected] centosyum]# rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
3 [[email protected] centosyum]# rpm -ivh yum-3.4.3-150.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm  //这两个一起安装

5.创建repo，参考：

 1 # CentOS-Base.repo
 2 #
 3 # The mirror system uses the connecting IP address of the client and the
 4 # update status of each mirror to pick mirrors that are updated to and
 5 # geographically close to the client.  You should use this for CentOS updates
 6 # unless you are manually picking other mirrors.
 7 #
 8 # If the mirrorlist= does not work for you, as a fall back you can try the 
 9 # remarked out baseurl= line instead.
10 #
11 #

1  yum clean all
2  yum makecache  //这条执行会较慢
3  yum repolist
