centos 使用RPM包安装指定版本的docker-engine

下面是拿安装docker-engine-1.10.3-1为例：

wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-1.10.3-1.el7.centos.x86_64.rpm

wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-selinux-1.10.3-1.el7.centos.noarch.rpm

yum localinstall -y docker-engine*

rm -f docker-engine-1.10.3-1.el7.centos.x86_64.rpm docker-engine-selinux-1.10.3-1.el7.centos.noarch.rpm

systemctl start docker
