阿里云CentOS 8.x系统yum报404的解决方法

Posted 2022-05-18 wemux

进入cd /etc/yum.repos.d/路径下

对文件进行重命名备份

rename .repo .repo.bak /etc/yum.repos.d/*.repo

新建一个bak文件夹

mkdir bak

.bak文件移动到bak文件夹下

mv *.bak /etc/yum.repos.d/bak

下载最新的repo文件

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文件中的链接

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

重新创建缓存,若没报错,则正常了

yum clean all && yum makecache
