错误一:
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/CentOS-Linux-BaseOS.repo; Configuration: OptionBinding with id "failovermethod" does not existCentOS Linux 8 - AppStream 6.3 kB/s | 2.3 kB00:00 Errors during downloading metadata for repository 'appstream':- Status code: 404 for http://mirrors./centos/8/AppStream/x86_64/os/repodata/repomd.xml (IP: 100.100.2.148)Error: Failed to download metadata for repo 'appstream': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
当前环境为:
[root@iZ2vc5xk901ftf2vfscwc1Z yum.repos.d]# uname -srmLinux 4.18.0-348.2.1.el8_5.x86_64 x86_64
CentOS版本为:
[root@iZ2vc5xk901ftf2vfscwc1Z yum.repos.d]# cat /etc/redhat-releaseCentOS Linux release 8.5.2111
解决办法:
1.找到CentOS相关目录,备份CentOS-AppStream,CentOS-Base文件,一般CentOS目录在/etc/yum.repos.d文件夹下,如下:
备份:
cp CentOS-Linux-AppStream.repo CentOS-Linux-AppStream.repo1cp CentOS-Linux-BaseOS.repo CentOS-Linux-BaseOS.repo1
2.编辑文件CentOS-Linux-AppStream.repo,CentOS-Linux-BaseOS.repo进行字符串替换:
vi CentOS-Linux-BaseOS.repo# esc 键盘 ： 命令模式下执行：%s/mirrors.//g # 继续执行:%s/$releasever/$releasever-stream/gvi CentOS-Linux-AppStream.repo# esc 键盘 ： 命令模式下执行：%s/mirrors.//g # 继续执行:%s/$releasever/$releasever-stream/g
3.执行命令:
yum makecacheyum update
命令执行效果:
[root@iZ2vc5xk901ftf2vfscwc1Z yum.repos.d]# yum updateInvalid configuration value: failovermethod=priority in /etc/yum.repos.d/CentOS-Linux-epel.repo; Configuration: OptionBinding with id "failovermethod" does not existLast metadata expiration check: 0:01:22 ago on Wed 09 Mar 10:20:01 AM CST.Error: Problem: package centos-stream-release-8.6-1.el8.noarch requires centos-stream-repos, but none of the providers can be installed- package centos-linux-repos-8-3.el8.noarch conflicts with centos-repos(8) provided by centos-stream-repos-8-2.el8.noarch- package centos-stream-repos-8-2.el8.noarch conflicts with centos-repos(8) provided by centos-linux-repos-8-3.el8.noarch- package centos-linux-repos-8-3.el8.noarch conflicts with centos-repos(8) provided by centos-stream-repos-8-3.el8.noarch- package centos-stream-repos-8-3.el8.noarch conflicts with centos-repos(8) provided by centos-linux-repos-8-3.el8.noarch- package centos-linux-repos-8-3.el8.noarch conflicts with centos-repos(8) provided by centos-stream-repos-8-4.el8.noarch- package centos-stream-repos-8-4.el8.noarch conflicts with centos-repos(8) provided by centos-linux-repos-8-3.el8.noarch- cannot install the best update candidate for package centos-linux-release-8.5-1.2111.el8.noarch- problem with installed package centos-linux-repos-8-3.el8.noarch(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

oK,可以进行yum安装啦.
注意：实际使用中如果没有 CentOS-AppStream.repo相关文件， 则不对其进行操作
eg:安装git:

错误二:
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/CentOS-Linux-epel.repo; Configuration: OptionBinding with id "failovermethod" does not existRepository extras is listed more than once in the configurationCentOS Linux 8 - AppStream 6.7 kB/s | 2.3 kB00:00 Errors during downloading metadata for repository 'appstream':- Status code: 404 for http://mirrors./centos/8/AppStream/x86_64/os/repodata/repomd.xml (IP: xxx.xxx.xxx.xxx)Error: Failed to download metadata for repo 'appstream': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
解决方法
进入文件 /etc/yum.repos.d/CentOS-Epel.repo，将 failovermethod=priority 注释:
ok, 这样也可以进行yum安装
错误三:
Errors during downloading metadata for repository 'appstream':- Status code: 404 for http://mirrors./centos/8/AppStream/x86_64/os/repodata/repomd.xml (IP: xxx.xxx.xxx.xxx)Error: Failed to download metadata for repo 'appstream': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
这个错误的意思是: 为仓库 'base' 下载元数据失败
那么我们就要考虑是不是yum源的问题了,因为上面说了,我们的系统是CentOS Linux release 8.5.2111版本的,而CentOS 8操作系统版本结束了生命周期（EOL），Linux社区已不再维护该操作系统版本
背景信息
12月31日CentOS 8 EOL。按照社区规则，CentOS 8的源地址/centos/8/内容已移除，目前第三方的镜像站中均已移除CentOS 8的源。阿里云的源http://mirrors.和也无法同步到CentOS 8的源。当您在阿里云上继续使用默认配置的CentOS 8的源会发生报错。报错示例如下图所示：
您可以通过下文的操作步骤，在CentOS 8操作系统的ECS实例中将源配置按照网络环境不同进行切换。
yum源：专有网络VPC类型实例需切换为http://mirrors./centos-vault/8.5.2111源。
epel源：专有网络VPC类型实例需切换为http://mirrors./epel-archive/8/源
官方操作布置,如下:
1.登录CentOS 8系统的ECS实例
2.运行以下命令备份之前的repo文件。
rename '.repo' '.repo.bak' /etc/yum.repos.d/*.repo
3.运行以下命令下载最新的repo文件。
wget /repo/Centos-vault-8.5.2111.repo -O /etc/yum.repos.d/Centos-vault-8.5.2111.repowget /repo/epel-archive-8.repo -O /etc/yum.repos.d/epel-archive-8.repo
4.运行以下命令替换repo文件中的链接。
sed -i 's/mirrors./url_tmp/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's//mirrors./g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/url_tmp//g' /etc/yum.repos.d/Centos-vault-8.5.2111.reposed -i 's//mirrors./g' /etc/yum.repos.d/epel-archive-8.repo
5.运行以下命令重新创建缓存。
yum clean all && yum makecache
yum源和epel源切换完成后，即可使用yum install命令在实例上安装您所需要的软件包
跟着官方的步骤走下去，最后如果有报错，下面是正确解决流程:
1.进入/etc/yum.d.repos.d/,运行以下命令备份之前的repo文件
rename '.repo' '.repo.bak' /etc/yum.repos.d/*.repo
2.运行以下命令下载最新的repo文件:
wget /repo/Centos-vault-8.5.2111.repo -O /etc/yum.repos.d/Centos-vault-8.5.2111.repowget /repo/epel-archive-8.repo -O /etc/yum.repos.d/epel-archive-8.repo
3.运行以下命令替换repo文件中的链接，这一步出错了,官方提供的命令：
sed -i 's/mirrors./url_tmp/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's//mirrors./g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/url_tmp//g' /etc/yum.repos.d/Centos-vault-8.5.2111.reposed -i 's//mirrors./g' /etc/yum.repos.d/epel-archive-8.repo
http://mirrors. 需要替换为 ，但是官方提供的命令没替换完，如果有执行官方提供的命令还是不行的话执行下面的命令：
sed -i 's/mirrors.//g' /etc/yum.repos.d/Centos-vault-8.5.2111.reposed -i 's/mirrors.//g' /etc/yum.repos.d/epel-archive-8.repo
运行以下命令重新创建缓存
yum clean all && yum makecache
执行成果，yum install也就可以正常使用了~
