谬误:为 repo ‘base’ 下载元数据失败

解决办法:
大家能够依照如下流程批改源
1.备份现有源

mv /etc/yum.repos.d /etc/yum.repos.d.backup

2.设置新的yum目录

mkdir /etc/yum.repos.d

3.装置wget(我没装置,也没事,可能是我以前装置过)

yum install -y wget

4.就是坑了我一早晨的下载配置(大家肯定要辨别本人的零碎版本,不然必定不通过)

CentOS 5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

CentOS 6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

CentOS 7

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

CentOS 8

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo

5.革除文件并重建元数据缓存

yum clean allyum makecache

6.最初更新软件包,这一步要下载安装或降级软件包,比拟费时间!

yum update -y
