本文介绍如何在CentOS上安装Docker。首先确保系统内核版本为3.10及以上，并通过sudo权限更新yum包。使用curl命令运行Docker安装脚本，启动Docker守护进程，并通过运行hello-world镜像验证安装成功。

Docker requires a 64-bit installation regardless of your CentOS version. Also, your kernel must be 3.10 at minimum, which CentOS 7 runs.

[root@VM_225_102_centos ~]# uname -a
Linux VM_225_102_centos 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

如果系统有网：

Log into your machine as a user with sudo or root privileges.
Make sure your existing yum packages are up-to-date.

```
$ sudo yum update
```
Run the Docker installation script.
```
$ curl -fsSL https://get.docker.com/ | sh
```
This script adds the docker.repo repository and installs Docker.
Start the Docker daemon.
```
$ sudo service docker start
```
Verify docker is installed correctly by running a test image in a container.
```
$ sudo docker run hello-world
```

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c04b14da8d14: Pull complete
Digest: sha256:0256e8a36e2070f7bf2d0b0763dbabdd67798512411de4cdcf9431a1feb60fd9
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
