1.服务器升级系统到centos8，发现无法使用yum update

错误为：Failed to synchronize cache for repo ‘AppStream’, ignoring this repo.

2.修复之法：

2.1:检测网络是否通畅

2.2：修改 baseurl 的地址 http://mirrors.cloud.aliyuncs.com（在另外一台机器上好用，这台怎么都ping不通）

替换成http://mirrors.aliyun.com

即可，这两个地址可以尝试下哪个好用,把/etc/yum.repos.d/下的.repo文件都替换下，主要是下面三个

/etc/yum.repos.d/CentOS-AppStream.repo
/etc/yum.repos.d/CentOS-Base.repo
/etc/yum.repos.d/CentOS-Extras.repo

替换：
vi /etc/yum.repos.d/CentOS-Base.repo

[BaseOS]
name=CentOS-$releasever - Base
baseurl=http://mirrors.aliyun.com/$contentdir/$releasever/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

vi /etc/yum.repos.d/CentOS-AppStream.repo

[AppStream]
name=CentOS-$releasever - AppStream
baseurl=http://mirrors.aliyun.com/$contentdir/$releasever/AppStream/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

3.修改完之后执行 dnf命令或者yum 命令都可以

dnf clean all # 清除所有的缓存文件

dnf makecache # 制作元数据缓存

~谢谢打赏~
