Linux yum换源

替换yum源

一、yum源更换

1、通过管道检查是否有yum包

rpm -qa |grep yum

2、删除自带的yum包

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

3、重复检查是否有yum包

rpm -qa |grep yum

4、下载yum源所需要的包以及依赖项

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/
rpm4.11.3-45.el7.x86_64.rpm 

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/
python-urlgrabber-3.10-10.el7.noarch.rpm

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm 

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-54.el7_8.noarch.rpm  

5、yum源注册

rpm -Uvh rpm-4.11.3-45.el7.x86_64.rpm --nodeps
rpm -Uvh python-urlgrabber-3.10-10.el7.noarch.rpm --nodeps
rpm -ivh yum-*

6、进入设置路径

cd /etc/yum.repos.d/

7、将所有的releasever替换成7

sed -i 's#$releasever#7#g' CentOS7-Base.repo

8、清除yum缓存

yum clean all

9、更新yum源

yum makecache

10、安装一下vim测试当前是否安装成功

yum install vim
