我使用AWS EC2在Ubuntu 14.04上运行了带有gunicorn和nginx的烧瓶应用程序。我已从/ etc / nginx / sites-available和/ etc / nginx / sites-enabled中删除了默认站点。在这两个文件夹中，只有一个文件：flasky - 我的nginx文件如下：

当我在浏览器中输入服务器的IP时，会显示默认的Nginx静态页面。如果我转到/ auth / login，Flask提供的正确页面会正确显示。
如果将端口从80更改为8080，请重新启动Nginx，输入http://ip-address:8080，然后所有Flask页面都能正常工作。我不知道如何解决80端口的问题。请帮忙！谢谢！
更新：我刚刚发现，如果我使用AWS公共DNS：http://ec2-50-112-125-180.us-west-2.compute.amazonaws.com，它就可以了。但是如果我使用相应的弹性IP：50.112.125.180，它会显示nginx默认页面。谁知道为什么？
答案 0 :(得分：0)
在nginx.conf中搜索单词include
也许它包括配置文件的其他目录。
此外，可能还有其他配置块
location /
取代此部分也有listen 80。
