1.卸载旧版本Docker
sudo yum remove docker docker-common docker-selinux docker-engine
2.执行以下命令安装依赖包
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
3.鉴于国内网络问题，强烈建议使用国内源执行下面的命令添加 yum 软件源
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
4.安装Docker CE
sudo yum -y install docker-ce
5.设置开机启动 Docker CE

sudo systemctl enable docker sudo systemctl start docker
6.鉴于国内网络问题，后续拉取 Docker 镜像十分缓慢，强烈建议安装 Docker 之后配置 国内镜像加速
sudo vi /etc/docker/daemon.json { "registry-mirrors": ["https://registry.docker-cn.com"] }
7.重启生效
sudo systemctl daemon-reload sudo systemctl restart docker
8.安装docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose docker-compose --version sudo curl -L "https://get.daocloud.io/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.0/docker-compose-`uname -s-uname -m` > /usr/local/bin/docker-compose
国内镜像安装 docker-compose
按照官网操作
sudo curl -L “https://github.com/docker/compose/releases/download/1.24.0/docker-compose-(uname−s)− (uname -s)-(uname−s)−(uname -m)” -o /usr/local/bin/docker-compose
实在太慢！所以，又去找了一下国内镜像。
国内镜像参考文章：
https://blog.csdn.net/huiyanghu/article/details/82253886
按照以上参考文章抄过来。
curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.0/docker-compose-`uname -s-uname -m` > /usr/local/bin/docker-compose
果然秒达！接下来设置可运行
chmod +x /usr/local/bin/docker-compose
确认一下：
$docker-compose --version
docker-compose version
1.24.0, build 0aa59064
