解决centos10中使用yum 安装提示在“/etc/yum.repos.d“, “/etc/yum/repos.d“, “/etc/distro.repos.d“中没有被启用的仓库的问题

针对没有可用的软件源的处理如果提示404 说明阿里云的那个链接已经失效了 需要更换方案1:中科大 vault 源国内快cd /etc/yum.repos.d/ cat CentOS-Base.repo EOF [base] nameCentOS-7 - Base baseurlhttps://mirrors.ustc.edu.cn/centos-vault/7.9.2009/os/$basearch/ gpgcheck1 gpgkeyfile:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 enabled1 [updates] nameCentOS-7 - Updates baseurlhttps://mirrors.ustc.edu.cn/centos-vault/7.9.2009/updates/$basearch/ gpgcheck1 gpgkeyfile:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 enabled1 [extras] nameCentOS-7 - Extras baseurlhttps://mirrors.ustc.edu.cn/centos-vault/7.9.2009/extras/$basearch/ gpgcheck1 gpgkeyfile:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 enabled1 EOF yum clean all yum makecache上面的命令,建议先切换到root模式sudo -i直接整体复制后粘贴执行即可,结果如下方案2: 官方 vault.centos.org最稳cd /etc/yum.repos.d/ # 清空并写入新源 cat CentOS-Base.repo EOF [base] nameCentOS-7 - Base baseurlhttp://vault.centos.org/7.9.2009/os/$basearch/ gpgcheck1 gpgkeyfile:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 enabled1 [updates] nameCentOS-7 - Updates baseurlhttp://vault.centos.org/7.9.2009/updates/$basearch/ gpgcheck1 gpgkeyfile:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 enabled1 [extras] nameCentOS-7 - Extras baseurlhttp://vault.centos.org/7.9.2009/extras/$basearch/ gpgcheck1 gpgkeyfile:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 enabled1 EOF # 重建缓存 yum clean all yum makecache执行结果如下后面就能使用(安装 Docker 的前置依赖)yum install -y yum-utils device-mapper-persistent-data lvm2运行结果如下:
