异常分析解决
A new obsoletes restriction was introduced in docker-ce 17.06.0 and it looks like the yum repo is applying it to all versions of the docker-ce indiscriminately. To work around this when installing older versions of docker-ce, you can pass a flag to ignore obsoletes:
总之，一句话，安装较早版本的docker时，忽略obsoletes即可
$ yum install -y --setopt=obsoletes=0 \ docker-ce-17.03.1.ce-1.el7.centos \ docker-ce-selinux-17.03.1.ce-1.el7.centos
