簡單版：
1.執(zhí)行命令curl -sSL https://get.daocloud.io/docker | sh
? 前提：
? ? a.虛擬機可以上網(wǎng)
? ? b.Centos為64位
? ? c.要用root用戶
2.看docker版本? docker -v
3.從HelloWorld開始
? a.service docker start
? b.docker run hello-world
出現(xiàn)HelloWorld就說明成功啦~
帶具體結(jié)果的版本：
1.執(zhí)行命令DaoCloud的安裝本(是好的，哈哈)：
curl -sSL https://get.daocloud.io/docker | sh
執(zhí)行命令前，要記得切換到root用戶下，避免因為權(quán)限引起一系列的問題
[root@192 ~]# curl -sSL https://get.daocloud.io/docker | sh

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
? sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run
? ? ? ? containers which can be used to obtain root privileges on the
? ? ? ? docker host.
? ? ? ? Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
? ? ? ? for more information.
2.查看docker的版本
[root@192 ~]# docker -v
Docker version 17.12.0-ce, build c97c6d6
3.從第一個helloworld開始，證明docker安裝成功啦~~~
[root@192 ~]# docker run hello-world
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.
[root@192 ~]# service docker start
Redirecting to /bin/systemctl start docker.service
[root@192 ~]# docker run hello-world

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
