1、通过 RPM 安装 docker 17.03.0 版本并且配置 docker 阿里加速
docker-ce-17.03：https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
docker-ce-selinux-17.03：https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
下载好rpm包后直接yum安装，装完后将iptables的默认规则清空后启动docker服务，启动第一个容器测试是否能正常拉取镜像。接着配置阿里云镜像加速。
[root@localhost ~]# wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.03.0.ce-1.el7.centos.x86_64.rpm
[root@localhost ~]# wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-selinux-17.03.0.ce-1.el7.centos.noarch.rpm
[root@localhost ~]# yum install -y *
[root@localhost ~]# systemctl enable --now docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /etc/systemd/system/docker.service.

[root@localhost ~]# 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

##针对Docker客户端版本大于 1.10.0 的用户可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器
##阿里云加速，前往http://cr.console.aliyun.com获取自己的加速地址，可以按照阿里云的配置说明配置加速，也可以将加速地址写入service文件中。
###写入service文件，ExecStart后写上加速地址
ExecStart=/usr/bin/dockerd --registry-mirror=https://********.mirror.aliyuncs.com
systemctl daemon-reload
systemctl restart docker
###查看加速是否成功，如下看到加速地址信息则说明加速成功
[root@localhost ~]# ps -ef | grep docker
root 2310 1 0 22:05 ? 00:00:04 /usr/bin/dockerd --registry-mirror=https://5bkin14v.mirror.aliyuncs.com
root 2316 2310 0 22:05 ? 00:00:01 docker-containerd -l unix:///var/run/docker/libcontainerd/docker-containerd.sock --metrics-interval=0 --start-timeout 2m --state-dir /var/run/docker/libcontainerd/containerd --shim docker-containerd-shim --runtime docker-runc
root 2474 1539 0 22:30 pts/0 00:00:00 grep --color=auto docker
2、通过 docker 安装一个 LAPM 架构
- 拉取lamp镜像
[root@localhost lib]# docker search lamp

[root@localhost ~]# docker run --name lamp -d -p 80:80 -p 3306:3306 -v /data/docker/mysql:/var/lib/mysql tutum/lamp

#--name:指定容器运行时的名字
#-d:后台方式运行
#-v:将容器MySQL数据目录映射到宿主机
#-p:将容器的对应端口映射到宿主机端口
浏览器输入宿主机地址，查看测试页面。
3、写出 docker run 命令的延申指令，如怎么在停止一个 docker 容器的时候自动删除该容器
[root@localhost ~]# docker run --name httpd -p 80:80 -d httpd
f1a6193014cdd41101e1fbd1a872bd40ed07a7d86177113b3fe07e2fbae3672f
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f1a6193014cd httpd "httpd-foreground" 11 seconds ago Up 11 seconds 0.0.0.0:80->80/tcp httpd
a06faf0304e8 hello-world "/hello" 7 minutes ago Exited (0) 7 minutes ago condescending_lewin
[root@localhost ~]# docker stop f1a6193014cd | xargs docker rm
f1a6193014cd
[root@localhost ~]# docker ps -a -q
a06faf0304e8
4、写出 docker run 命令在自动启动 docker 服务时通过什么参数能够启动 docker 中的容器，从而实现容器随着 docker 服务的启动而自动启动
[root@localhost ~]# docker run --name httpd -p 80:80 -d --restart=always httpd
886cb4f143c09f28a328925de7f48555a22d5fbdb166ab2bb4742758476ac424
##增加--restart参数设置容器随宿主机启动而自动启动
[root@localhost ~]# reboot
Connection closing...Socket close.
