安装aarch64的centos的yum源

1. 没网

   先进行断网检测,发现DNS没有配置对

2. 配置DNS

   修改/etc/resolv.conf

   # Generated by NetworkManager
   nameserver 114.114.114.114
   # 建议查本身使用的DNS服务器

3. 更新yum

   发现老是报错

   Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was

   用浏览器能够访问，提示网址http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock查看了一下。获取到

   而后就设置了华为的源。清华源也能够。用的是altarch。

   # CentOS-Base.repo
   #
   # The mirror system uses the connecting IP address of the client and the
   # update status of each mirror to pick mirrors that are updated to and
   # geographically close to the client.  You should use this for CentOS updates
   # unless you are manually picking other mirrors.
   #
   # If the mirrorlist= does not work for you, as a fall back you can try the
   # remarked out baseurl= line instead.

   清理并更新

   yum clean all
   yum makecache
   yum update

5. 指令修改

   sed -i -E -e 's;^mirrorlist=;#mirrorlist=;' -e 's;^ *# *baseurl=http://mirror.centos.org/altarch/;baseurl=http://mirrors.huaweicloud.com/centos-altarch/;' /etc/yum.repos.d/*.repo
