安装步骤:

EPEL 是yum的一个软件源,里面包含了许多基本源里没有的软件了,但在我们在使用epel时是需要安装它才可以了,EPEL,即Extra Packages for Enterprise Linux的简称,是为企业级linux提供的一组高质量的额外软件包,包括但不限于Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Enterprise Linux (OEL),使用Docker之前安装EPEL源。

安装仓库

yum install epel-release -y

安装Docker

yum install docker

加入开机自动启动

chkconfig docker on

启动Docker

service docker start

安装测试:

docker run hello-world

运行结果如下表示成功:

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
