工作准备
1、CentOS 7 虚拟机
2、docker-ce、docker-ce-cli、containerd.ior的rpm安装包
3、配置好虚拟机网络、确保可以更新依赖软件
安装docker
1、进入到docker的rpm安装包所在路径执行以下命令：
# yum -y install *.rpm

Complete!2、配置docker镜像仓库地址：
# vi /etc/docker/daemon.json
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
}注：若已启动docker请使用命令“systemctl daemon-reload”重新加载配置或使用命令“systemctl restart docker.service”重启docker
3、启动docker
# systemctl start docker简单使用docker
1、查看docker版本
# docker --version
Docker version 19.03.0, build aeac9490dc2、运行hello-world容器检查docker是已经否正确安装
# docker run hello-world
Unable to find image 'hello-world:latest' locally

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
