1. 下载docker的rpm以及相关依赖
yum install --downloadonly --downloaddir=/tmp/docker docker
报错：
Error: docker-ce-cli conflicts with 2:docker-1.13.1-109.gitcccb291.el7.centos.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
[root@centos7 tmp]# yum list installed | grep docker docker-ce-cli.x86_64 1:18.09.6-3.el7 installed
[root@centos7 tmp]# yum -y remove docker-ce-cli.x86_64
再次下载：
[root@centos7 tmp]# yum install --downloadonly --downloaddir=/tmp/docker docker
