错误一:
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/CentOS-Linux-BaseOS.repo; Configuration: OptionBinding with id "failovermethod" does not exist
CentOS Linux 8 - AppStream 6.3 kB/s | 2.3 kB 00:00
Errors during downloading metadata for repository 'appstream':
- Status code: 404 for http://mirrors.cloud.aliyuncs.com/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 -srm
Linux 4.18.0-348.2.1.el8_5.x86_64 x86_64
CentOS版本为:
[root@iZ2vc5xk901ftf2vfscwc1Z yum.repos.d]# cat /etc/redhat-release
CentOS 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.repo1
cp 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.cloud.aliyuncs.com/mirrors.aliyun.com/g
# 继续执行:
%s/$releasever/$releasever-stream/g
vi CentOS-Linux-AppStream.repo
# esc 键盘 ： 命令模式下执行：
%s/mirrors.cloud.aliyuncs.com/mirrors.aliyun.com/g
# 继续执行:
%s/$releasever/$releasever-stream/g
3.执行命令:
yum makecache
yum update
命令执行效果:
[root@iZ2vc5xk901ftf2vfscwc1Z yum.repos.d]# yum update

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:
[root@iZ2vc5xk901ftf2vfscwc1Z yum.repos.d]# yum -y install 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 exist
Repository extras is listed more than once in the configuration
CentOS Linux 8 - AppStream 6.7 kB/s | 2.3 kB 00:00
Errors during downloading metadata for repository 'appstream':
- Status code: 404 for http://mirrors.cloud.aliyuncs.com/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.cloud.aliyuncs.com/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
2021年12月31日CentOS 8 EOL。按照社区规则，CentOS 8的源地址http://mirror.centos.org/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.cloud.aliyuncs.com和http://mirrors.aliyun.com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.cloud.aliyuncs.com/centos-vault/8.5.2111源。
epel源：专有网络VPC类型实例需切换为http://mirrors.cloud.aliyuncs.com/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 https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo -O /etc/yum.repos.d/Centos-vault-8.5.2111.repo
wget https://mirrors.aliyun.com/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.cloud.aliyuncs.com/url_tmp/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/url_tmp/mirrors.aliyun.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo
sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/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 https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo -O /etc/yum.repos.d/Centos-vault-8.5.2111.repo
wget https://mirrors.aliyun.com/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.cloud.aliyuncs.com/url_tmp/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo && sed -i 's/url_tmp/mirrors.aliyun.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo
sed -i 's/mirrors.aliyun.com/mirrors.cloud.aliyuncs.com/g' /etc/yum.repos.d/epel-archive-8.repo
http://mirrors.cloud.aliyuncs.com 需要替换为http://mirrors.aliyun.com ，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.cloud.aliyuncs.com/mirrors.aliyun.com/g' /etc/yum.repos.d/Centos-vault-8.5.2111.repo
sed -i 's/mirrors.cloud.aliyuncs.com/mirrors.aliyun.com/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~
