在 AWS EC2 上部署 django 应用程序时无法在端口 80 上运行 gunicorn

Question

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

但它无法在端口 80 运行

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

我试图按照这个答案（虽然我无法理解，什么是部署脚本？） 让 Gunicorn 在端口 80 上运行

但它没有用。

我也尝试使用提升的权限sudo运行它，但徒劳无功。 在端口 80 上运行时出错：

使用sudo运行时出现此错误：

Answer 1

正如评论中所建议的，不建议在端口80上运行gunicorn 。

我们改为在大于1024端口（非特权端口）上运行它，并通过反向 poxy 请求到大于1014端口在gunicorn运行。

这可以通过编辑nginx配置文件来完成。

Answer 2

**您似乎没有将端口 80 添加到您的安全组中。

此外，您必须在命令访问端口 80 之前使用sudo

希望这可以帮助**
