[root@bogon .ssh]#2. 解决方法
2.1 在线安装
2.1.1检查 YUM 源配置
确保 YUM 源的配置正确。你可以通过查看 /etc/yum.repos.d/ 目录中的 .repo 文件来确认。
运行以下命令检查 YUM 源：
cat /etc/yum.repos.d/CentOS-Stream-8.repo
确保 baseurl 指向有效的镜像地址。2.1.2 修改镜像源
如果你发现当前的镜像源不可用，可以尝试更换为其他镜像地址。以下是一个示例：
[centos-stream8-base]
name=CentOS Stream 8 - Base
baseurl=http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centos8
[centos-stream8-extras]
name=CentOS Stream 8 - Extras
baseurl=http://mirror.centos.org/centos/8-stream/Extras/x86_64/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centos8
[centos-stream8-appstream]
name=CentOS Stream 8 - AppStream
baseurl=http://mirror.centos.org/centos/8-stream/AppStream/x86_64/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centos82.1.3 清理 YUM 缓存
yum clean all2.1.4 重试安装
执行一下命令安装即可
