Python Can'；在AWS EC2上部署django应用程序时，不要在端口80上运行gunicorn

我正在EC2 AWS中运行Ubuntu14.04实例

我可以运行

gunicorn-b0.0.0.0:8000 myapp.wsgi

但它无法在端口80运行

gunicorn-b0.0.0.0:80 myapp.wsgi

-->失败

我试图遵循这个答案（但我无法理解，部署脚本是什么？）

但它不起作用

我还尝试过以提升权限

sudo

运行它，但没有成功。 在端口80处运行时出错：

ubuntu@ip-172-31-39-159:~/jeequery$ gunicorn -b 0.0.0.0:80 rubiks.wsgi

使用

sudo

运行时，出现以下错误：

正如评论中所建议的，不建议在端口

80

上运行

gunicorn

相反，我们在大于

1024的端口（非特权端口）上运行它，并通过反向poxy请求在
gunicorn
上运行大于
1014的端口

这可以通过编辑nginx
config文件来完成。
**您似乎还没有将端口80添加到安全组中

在命令访问端口80之前，您还必须使用
sudo

希望这有帮助**
你说失败是什么意思？请详细说明错误。@beezz用错误日志更新了答案是否确实要这样做？gunicorn不太适合直接接触互联网；通常，您会在反向代理之后运行它。既然您已经运行了nginx，您应该重新启用它并按原样使用它。正如我所说的，您在端口80上运行nginx，并将其用作gunicorn前面的反向代理。不要尝试在端口80上运行gunicorn本身。gunicorn文档有一个完整的配置示例。这并不能回答问题。提问者特别提到他希望gunicorn在端口80上运行。您建议使用nginx作为反向代理，然后在端口8000上运行gunicorn。如果我们不想使用nginx或任何其他反向代理服务器呢？
