CentOS7安装Docker
【提示：docker-io是早期版本，docker-ce是社区版，docker-ee是企业版】
检查内核版本：需要大于3.0
[root@localhost admin]# uname -r
3.10.0-693.el7.x86_64
==================================2019-08-30更新
看了下官网，还是按照官网的来：
1. 先移除老的docker版本
yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-engine
2. 设置yum Repository。（这一步可省略，仅仅为了下载快一点）
yum install -y yum-utils device-mapper-persistent-data lvm2 yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
国内yum源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
3. 列出docker-ce（社区版）的列表
[root@localhost admin]# yum list docker-ce --showduplicates | sort -r * updates: centos.ustc.edu.cn Loading mirror speeds from cached hostfile Loaded plugins: fastestmirror, langpacks * extras: mirrors.cqu.edu.cn docker-ce.x86_64 3:19.03.1-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.0-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.8-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.7-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.6-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.5-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.4-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.3-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.2-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.1-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.0-3.el7 docker-ce-stable docker-ce.x86_64 18.06.3.ce-3.el7 docker-ce-stable docker-ce.x86_64 18.06.2.ce-3.el7 docker-ce-stable docker-ce.x86_64 18.06.1.ce-3.el7 docker-ce-stable docker-ce.x86_64 18.06.0.ce-3.el7 docker-ce-stable docker-ce.x86_64 18.03.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 18.03.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.12.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.12.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.09.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.09.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.06.2.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.06.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.06.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.03.3.ce-1.el7 docker-ce-stable docker-ce.x86_64 17.03.2.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.03.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.03.0.ce-1.el7.centos docker-ce-stable * base: mirrors.nju.edu.cn Available Packages
4. 安装
# 你可以安装想要的版本 yum install -y docker-ce-<VERSION_STRING>
如何找出版本号呢，比如 3:19.03.1-3.el7 ，版本号就是 19.03.1
我们还是直接安装吧（默认安装最新的）

启动
简略版本信息
配置一下国内镜像
[root@localhost admin]# vim /etc/docker/daemon.json { "registry-mirrors": ["https://2148hpzn.mirror.aliyuncs.com","http://hub-mirror.c.163.com"] }
# 重启服务 systemctl daemon-reload systemctl restart docker
运行hello-world
==================================更新完
第一步、切换成root用户并update yum
yum update
第二步、安装Docker
yum -y install docker-io
以下是运行结果

第三步、运行Docker
[root@localhost admin]# systemctl start docker
第四步、运行Hello-Word
[root@localhost admin]# docker run hello-world Unable to find image 'hello-world:latest' locally Trying to pull repository docker.io/library/hello-world ... latest: Pulling from docker.io/library/hello-world 9db2ca6ccae0: Pull complete Digest: sha256:4b8ff392a12ed9ea17784bd3c9a8b1fa3299cac44aca35a85c90c5e3c7afacdc Status: Downloaded newer image for docker.io/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. (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 Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/
