升级 redhat6 的 yum 源替换为 centos 源

1、查看源yum并卸载源yum

rpm -qa |grep yum



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

2、下载centos yum 安装包

wget https://vault.centos.org/6.10/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm --no-check-certificate

wget https://vault.centos.org/6.10/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm --no-check-certificate

wget https://vault.centos.org/6.10/os/x8664/Packages/yum-metadata-parser-1.1.2-16.el6.x8664.rpm --no-check-certificate

wget https://vault.centos.org/6.10/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm --no-check-certificate

3、安装

rpm -ivh python*

rpm -ivh yum*



4、删除源，源置

cd /etc/yum.repos.d/ && rm -f *.repo



5、清理软件源

yum clean all



6、配置新源：编辑文件：vi /etc/yum.repos.d/CentOS-Base.repo

[base]

name=CentOS-6

failovermethod=priority

#这个是官方的源 但是网上感人

#baseurl=https://vault.centos.org/6.10/os/x86_64/

#搜狐源 网速200k左右

baseurl=http://mirrors.sohu.com/centos/6.10/os/x86_64/

gpgcheck=0



7、建立源数据缓存

yum makecache
