Question

我在Ubuntu服务器上使用gunicorn和nginx运行Flask应用程序，但是当我加载页面时，我收到了504 Gateway Time-Out错误。这就是我在this之后设置应用程序的方法：

我在app中有一个名为/etc/nginx/sites-available/的文件，其中包含以下内容：

# Redirect www.psflask.net to psflask.net
server {
        server_name www.psflask.net;
        rewrite ^ http://psflask.net/ permanent;
}

# Handle requests to psflask.net on port 80
server {
        listen 80;
        server_name psflask.net;

                # Handle all locations
        location / {
                        # Pass the request to Gunicorn
                proxy_pass http://127.0.0.1:8000;

                # Set some HTTP headers so that our app knows where the
                # request really came from
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

我使用：

创建了一个符号链接

sudo ln -s /etc/nginx/sites-available/psflask.net /etc/nginx/sites-enabled/psflask.net

然后我用sudo service nginx restart

重新启动nginx

我用手枪：

gunicorn run:app -p psflask.pid -D

我尝试访问该页面但是，加载需要一段时间，然后我得到504网关超时错误。有什么问题？感谢。
