官方文档有详细操作，可以参考
https://docs.docker.com/install/linux/docker-ce/centos/如果有旧版本docker,请使用以下指令卸载
# yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine# yum install yum-utils device-mapper-persistent-data lvm2Docker CE有两种版本：
edge 版本每月发布一次，主要面向那些喜欢尝试新功能的用户。
stable 版本每3个月发布一次，维护期4个月。适用于希望更加容易维护的用户（稳定版）。
edge版本 只能在当前月份获得安全和错误修复。
stable版 在初始发布后4个月内接收关键错误修复和安全问题的修补程序。
Docker EE和stable版本的版本号保持一致。CE版并非阉割版，而是改了个名称；EE版则提供了一些收费的高级特性。stable 版本
# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
edge 版本
如果需要edge版本的docker,在上一条指令成功后启用下面一行命令
# yum-config-manager --enable docker-ce-edge# yum install docker-ce列出版本
# yum list docker-ce --showduplicates | sort -r

方法三：
通过运行hello-world 映像验证是否已正确安装，
# 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

1. 安装docker-compose
# pip install docker-compose
# pip install --upgrade pip 这一行指令是升级pip版本的，按需。
2.找到对应当前compose版本号的命令补全
# docker-compose version
/usr/lib/python2.7/site-packages/requests/__init__.py:80: RequestsDependencyWarning: urllib3 (1.22) or chardet (2.2.1) doesn‘t match a supported version!
RequestsDependencyWarning)
docker-compose version 1.23.1, build b02f130 这次安装的版本号是1.23.1
docker-py version: 3.5.1
CPython version: 2.7.5
OpenSSL version: OpenSSL 1.0.2k-fips 26 Jan 2017
有留意到吧，查看 docker-compose 的version时报不兼容的问题
解决它：
# pip uninstall urllib3 chardet
Uninstalling chardet-3.0.4:
Would remove:
/usr/bin/chardetect
/usr/lib/python2.7/site-packages/chardet-3.0.4.dist-info/*
/usr/lib/python2.7/site-packages/chardet/*
Would not remove (might be manually added):
/usr/lib/python2.7/site-packages/chardet/chardetect.py
/usr/lib/python2.7/site-packages/chardet/chardetect.pyo
/usr/lib/python2.7/site-packages/chardet/constants.py
/usr/lib/python2.7/site-packages/chardet/constants.pyo
Proceed (y/n)? y
Successfully uninstalled chardet-3.0.4
Uninstalling urllib3-1.22:
Would remove:
/usr/lib/python2.7/site-packages/urllib3-1.22.dist-info/*
/usr/lib/python2.7/site-packages/urllib3/*
Proceed (y/n)? y
Successfully uninstalled urllib3-1.22
重新安装
# pip install requests
Successfully installed chardet-3.0.4 urllib3-1.22
再执行就没问题了
# docker-compose version
docker-compose version 1.23.1, build b02f130
docker-py version: 3.5.1
CPython version: 2.7.5
OpenSSL version: OpenSSL 1.0.2k-fips 26 Jan 2017
3. 去https://github.com/docker/compose/
找到对应docker-compose版本的命令补全包
点开 Branch:master 边上的小倒三角，选Tags ,点中你的版本号
进入以下目录
compose/contrib/completion/这里是你喜欢的shell类型/docker-compose
点开这个文件，对着Raw复制下载地址(否则不对)
下载到系统中,
wget -O/etc/bash_completion.d/docker-compose https://raw.githubusercontent.com/docker/compose/1.23.1/contrib/completion/bash/docker-compose
生效当前shell
# exec bash在安装docker时，默认已经创建了docker用户组，该docker组授予与root 用户等效的权限。
# useradd -g docker docker
# passwd docker
设置这个普通用户密码
注销并重新登录，以便重新评估您的组成员身份。
如果在虚拟机上进行测试，则可能需要重新启动虚拟机才能使更改生效。
$ docker run hello-world
此命令下载测试映像并在容器中运行它。当容器运行时，它会打印一条信息性消息并退出
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.
