在CentOS上面搭建一個Docker,不要為我為什麼不用Ubuntu（因為某種我不想說的原因^_^）。
環境要求
Docker要求系統必須在CentOS 6以上，核心版本必須是2.6.32-431以上
檢視CentOS版本:
cat /etc/issue
CentOS release 6.7 (Final)
Kernel
on an m檢視核心版本:
uname -r
2.6.32-573.el6.x86_64安裝Docker
執行命令:
yum update
sudo yum install docker-io
第一條命令是更新下現有庫。
啟動Docker
sudo service docker start
tarting cgconfig service: [ OK ]
Starting docker: [ OK ]測試下Docker安裝是否成功,使用著名的hello world:
docker run hello-world
latest: Pulling from hello-world
3f12c794407e: Pull complete
975b84d108f1: Pull complete
Digest: sha256:8be990ef2aeb16dbcb9271ddfe2610fa6658d13f6dfb8bc72074cc1ca36966a7
Status: Downloaded newer image for hello-world:latest
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.
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
