-it，交互方式启动
–name nginx_test，指定新容器的名称是nginx_test
-h docker-nginx，指定新容器的主机名是docker-nginx
-p 8001:81 -p 8000:80，指定宿主机与docker容器的端口映射，宿主机的8001对应docker容器的81，宿主机的8000对应docker容器的80
-v /home/linuxidc/docker/nginx_web/:/home/visual/nginx_web/，指定宿主机与docker容器的文件映射，宿主机的/home/linuxidc/docker/nginx_web/ 对应docker容器的 /home/visual/nginx_web/
learn/nginx:v2，指定启动容器对应的镜像是learn/nginx:v2，可以是镜像ID
/bin/sh /etc/rc.local，指定容器启动后，执行shell脚本是/etc/rc.local
查看docker容器，容器nginx_test处于up状态，说明启动正常
linuxidc@linuxidc:~/docker/nginx_web$ docker ps -a

5、测试docker_nginx是否正常
通过浏览器测试8001端口
通过浏览器测试8000端口
修改宿主机的文件，并测试8001端口
修改宿主机的/home/linuxidc/docker/nginx_web/index.html文件
linuxidc@linuxidc:~/docker/nginx_web$ vi index.html
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx! I am in docker!</title>
<style>
body {
width: 35em;
margin: 0 auto;

</head>
<body>
<h1>Welcome to nginx! I am in Docker!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>
<p>For online documentation and support please refer to

<p><em>Thank you for using nginx.</em></p>

通过浏览器测试8001端口，发现“Welcome to nginx! I am in docker!”，说明内容已经修改，使用docker做为web服务器的功能已经OK
