确认安装环境：Redhat 7.6
[root@localhost ~]# mount /dev/sr0 /media/ #挂载磁盘
mount: /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]# yum-config-manager --add-repo=file:///media/ #添加yum仓库
注意：添加系统ISO为本地YUM仓库后，需要在.repo配置文件里添加gpgcheck=0的配置内容，否则用本地库安装软件会失败。
[root@localhost ~]# rpm -qa | grep libseccomp* #检查依赖包是否安装
libseccomp-2.3.1-3.el7.x86_64
[root@localhost ~]# rpm -qa | grep container-selinux* #检查依赖包是否安装
从阿里开源镜像站就可以下载该包，不安装这个软件包，docker会无法安装
