问题 手上有一台Centos8的服务器，使用一件脚本安装宝塔面板时，报以下错误
仔细看了下文档，原因主要是 2022年1月31日，CentOS团队从官方镜像中移除了CentOS 8的所有包，停止支持、如需安装建议更换Centos7系统或升级至Centos 8 Stream系统安装宝塔 继续使用8的话，可以替换成腾讯的镜像 腾讯yum源
替换yum源
腾云yum源： https://mirrors.tencent.com/help/centos.html

发现又有之前的问题，makecache报错 makache报错解决 CentOS8的yum.repos.d中，有CentOS-AppStream.repo、CentOS-Linux-Base.repo、CentOS-Linux-AppStream.repo这些文件，这些文件的源没有被替换，因此需要手动替换下这些文件源。 先看下正确的配置方式，即CentOS-Base.repo的配置

# 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.
