1、安装centos7 server with GUI版本。
2、上传docker并安装。
tar -zxvf docker-20.10.8.tgz #解压
cp docker/* /usr/bin/ #将解压出来的docker文件复制到 /usr/bin/ 目录下
#进入**/etc/systemd/system/**目录,并创建**docker.service**文件
cd /etc/systemd/system/
touch docker.service
vim docker.service注意： --insecure-registry=192.168.200.128 此处改为你自己服务器ip

WantedBy=multi-user.targetchmod 777 /etc/systemd/system/docker.service #给docker.service文件添加执行权限
systemctl daemon-reload #重新加载配置文件（每次有修改docker.service文件时都要重新加载下）、
systemctl start docker
systemctl enable docker.service
systemctl status docker
systemctl enable docker3、上传docker-compose并创建链接。
#上传docker-compose到/usr/local/bin下面
sudo chmod +x /usr/local/bin/docker-compose # 赋执行权限
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose # 做链接
docker-compose --version #查看docker—compose 版本
