docker -v 启动docker systemctl start docker 停止docker systemctl stop docker 查看状态docker systemctl status docker 查看docker版本 docker -v安装docker compose
curl -L https://github.com/docker/compose/releases/download/1.25.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose执行了docker-compose --version后输出如下所示表示安装成功
