具体错误如下:
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/CentOS-Linux-epel.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/gvi 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

再次执行命令yum install *expect*,结果如下:

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
