我在我的EC2 AWS中运行Ubuntu 14.04实例.

我可以运行gunicorn -b 0.0.0.0:8000 myapp.wsgi

但它无法在80端口运行

gunicorn -b 0.0.0.0:80 myapp.wsgi – >失败

我试着按照这个答案(我无法理解它,但部署脚本是什么？)Getting Gunicorn to run on port 80

但它没有用.

我也尝试用提升权限sudo运行它是徒劳的.
在端口80上运行时出错：

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

在使用sudo运行时出现此错误：

解决方法:

正如评论中所建议的那样,不建议在80端口运行gunicorn.

我们改为在大于1024(非特权端口)的端口上运行它,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配置文件来完成.
