使用Nginx和Gunicorn运行Flask应用

使用Nginx和Gunicorn运行Flask应用

这就是我在Nginx中提供我的Flask应用程序的方式：

使用套接字运行守护进程gunicorn：

  sudo gunicorn app:app --bind unix:/tmp/gunicorn_flask.sock -w 4 -D

相关的nginx配置：

    upstream flask_server {        # swap the commented lines below to switch between socket and port        server unix:/tmp/gunicorn_flask.sock fail_timeout=0;        #server 127.0.0.1:5000 fail_timeout=0;    }    server {        listen 80;        server_name www.example.com;        return 301 $scheme://example.com$request_uri;    }    server {        listen 80;        client_max_body_size 4G;        server_name example.com;        keepalive_timeout 5;        # path for static files        location  /static { alias /path/to/static; autoindex on; expires max;        }        location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; if (!-f $request_filename) {     proxy_pass http://flask_server;     break; }        }    }}
