centos 8.5 iso 下载 + 换源

OMG centos8.5 官方不支持了

iso 下载：http://mirrors.eecs.wsu.edu/centos-vault/8.5.2111/isos/x86_64/

安装时，网络镜像，需要设置好网络

mirrors.aliyun.com/centos/8/BaseOS/x86_64/os

 

rename '.repo' '.repo.bak' /etc/yum.repos.d/*.repo
wget https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo -O /etc/yum.repos.d/Centos-vault-8.5.2111.repo
wget https://mirrors.aliyun.com/repo/epel-archive-8.repo -O /etc/yum.repos.d/epel-archive-8.repo
sed -i 's/mirrors.cloud.aliyuncs.com/url_tmp/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/url_tmp/mirrors.aliyun.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo
sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/g' /etc/yum.repos.d/epel-archive-8.repo
sed -i 's/mirrors.cloud.aliyuncs.com/mirrors.aliyun.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo
sed -i 's/mirrors.cloud.aliyuncs.com/mirrors.aliyun.com/g' /etc/yum.repos.d/epel-archive-8.repo
yum clean all && yum makecache

 

备份原repo：
rename '.repo' '.repo.bak' /etc/yum.repos.d/*.repo
下载最新repo：
wget https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo -O /etc/yum.repos.d/Centos-vault-8.5.2111.repo
wget https://mirrors.aliyun.com/repo/epel-archive-8.repo -O /etc/yum.repos.d/epel-archive-8.repo
替换repo里面关键字：
sed -i 's/mirrors.cloud.aliyuncs.com/url_tmp/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/url_tmp/mirrors.aliyun.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo
sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/g' /etc/yum.repos.d/epel-archive-8.repo
二次替换关键字：
http://mirrors.cloud.aliyuncs.com需要替换为http://mirrors.aliyun.com，但是官方提供的命令没替换完，如果有执行官方提供的命令还是不行的话执行下面的命令。

sed -i 's/mirrors.cloud.aliyuncs.com/mirrors.aliyun.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo
sed -i 's/mirrors.cloud.aliyuncs.com/mirrors.aliyun.com/g' /etc/yum.repos.d/epel-archive-8.repo
清空yum原缓存：
yum clean all && yum makecache
