2、拉取nginx镜像 我这里拉取最新版的nginx

[root@lChen ~]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
852e50cd189d: Pull complete 
571d7e852307: Pull complete 
addb10abd9cb: Pull complete 
d20aa7ccdb77: Pull complete 
8b03f1e11359: Pull complete 
Digest: sha256:6b1daa9462046581ac15be20277a7c75476283f969cb3a61c8725ec38d3b01c3
Status: Downloaded newer image for nginx:latest
docker.io/library/nginx:latest

3、查看下载好的镜像，可以看到我服务器只有一个nginx镜像 非必要

[root@lChen ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              bc9a0695f571        2 weeks ago         133MB

4、启动nginx镜像

-d 后台启动
-name nginx 给这个容器起个名字，我这里还叫nginx，不写默认就是镜像名
-p 把容器的nginx端口80 映射到宿主机（服务器）端口7777

[root@lChen ~]# docker run -d --name nginx -p 7777:80 nginx
ac0719f6af28c67ac886e8ba5b691f1b734481e381b29e2cc8d6c9be9ed90573

5、查看进程

可以看到只有一个nginx容器正在运行 非必要

[root@lChen ~]# docker ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS         PORTS                  NAMES
ac0719f6af28        nginx               "/docker-entrypoint.…"   6 seconds ago       Up 5 seconds   0.0.0.0:7777->80/tcp   nginx

6、本机测试 容器的80端口映射到宿主机的7777 所以我们本机测试访问7777端口

[root@lChen ~]# curl localhost:7777
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>
<h1>Welcome to nginx!</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
<a href="http://nginx.org/">nginx.org</a>.<br/>

<a href="http://nginx.com/">nginx.com</a>.</p>



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

</body>
</html>

如果都跟以上一样就说明nginx已经成功了

7、外网访问 服务器公网ip：7777

发现无法访问，因为我的是阿里云服务器，需要在阿里云安全组里面把7777放出来

8、配置阿里云安全组规则

9、再去访问ip+7777

可以看到已经可以访问了
