卸载旧依赖

sudo yum remove docker \
                docker-client \
                docker-client-latest \
                docker-common \
                docker-latest \
                docker-latest-logrotate \
                docker-logrotate \
                docker-engine

安装 Docker Engine-Community

新主机上首次安装 Docker Engine-Community 之前，需要设置 Docker 仓库

1 设置仓库

sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

2 安装 Docker Engine-Community

sudo yum install docker-ce docker-ce-cli containerd.io

等待安装，中间会有几步提示让你输入，输入'y'即可

3 启动docker

sudo systemctl start docker

4 安装docker-compose

$curl -L https://github.com/docker/compose/releases/download/1.8.0/run.sh > /usr/local/bin/docker-compose
$ chmod +x /usr/local/bin/docker-compose

检查，输入 docker-compose --version ,若有输出，则安装成功
