Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

 

002、系统

[root@localhost test01]# hostnamectl        ## 系统
   Static hostname: localhost.localdomain
         Icon name: computer-vm

003、问题原因

centos8已经 停止维护

 

004、解决方法

a、进入yum仓库配置文件目录

[root@localhost test01]# cd /etc/yum.repos.d/        ## 进入yum仓库配置文件目录
[root@localhost yum.repos.d]# ls
CentOS-Linux-AppStream.repo          CentOS-Linux-FastTrack.repo
CentOS-Linux-BaseOS.repo             CentOS-Linux-HighAvailability.repo
CentOS-Linux-ContinuousRelease.repo  CentOS-Linux-Media.repo
CentOS-Linux-Debuginfo.repo          CentOS-Linux-Plus.repo
CentOS-Linux-Devel.repo              CentOS-Linux-PowerTools.repo
CentOS-Linux-Extras.repo             CentOS-Linux-Sources.repo

 

b、修改配置文件内容：

[root@localhost yum.repos.d]# sed -i 's/mirrorlist/#mirrorlist/g' CentOS-*   ## 注释掉 mirrorlist
[root@localhost yum.repos.d]# sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' CentOS-*
                                                                             ## 使baseurl生效，并修改域名

 

c、测试安装效果

[root@localhost yum.repos.d]# yum -y install httpd         ## 安装测试

 

问题解决。
