前一章docker安装成功了，这里来安装下Nginx试下。
注意要明确一点，镜像是类，容器是对象。
查看当前的镜像
docker images
看到只有一个测试的镜像。
拉取镜像：
docker pull nginx
下载成功后查看，镜像已经被下载下来了：
使用 nginx 镜像
运行容器：
docker run --name nginx_test -d -p 80:80 nginx
查看容器运行情况：
然后在浏览器输入网址：
修改文件：
[root@VM_0_4_centos bin]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8bf811453641 nginx "nginx -g 'daemon of…" 4 minutes ago Up 4 minutes 0.0.0.0:80->80/tcp nginx_test
记住这里的 CONTAINER ID ，这是容器的ID
进入容器，修改：
[root@VM_0_4_centos bin]# docker exec -it 8bf811453641 /bin/bash root@8bf811453641:/# cd /usr/share/nginx/html root@8bf811453641:/usr/share/nginx/html# echo "hello docker">index.html root@8bf811453641:/usr/share/nginx/html# exit
这是查看，修改的已经生效了。
如果想停止容器：
docker stop containerId // containerId 是容器的ID [root@VM_0_4_centos bin]# docker stop 8bf811453641
然后用docker ps 看容器运行状态就行。
到此，容器运行完毕，总体来说非常的简单。
下面追加挂载方法先创建目录
mkdir -p /data/nginx/{conf,conf.d,html,logs}
nginx配置文件
/data/nginx/conf/nginx.conf

<title>系统时间</title>
</head>
<body>
<h1 id="datetime">
<script>
setInterval("document.getElementById('datetime').innerHTML=new Date().toLocaleString();", 1000);
</script>
</h1>
</body>
删除容器
docker rm -f nginx-test
重新映射启动容器
docker run --name nginx-test -d -p 80:80 -v /data/nginx/html:/usr/share/nginx/html
-v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf
-v /data/nginx/logs:/var/log/nginx
-v /data/nginx/conf.d:/etc/nginx/conf.d -d nginx:latest
再次运行
