你好吗? 我在DigitalOcean上安装了Ubuntu 16.04的服务器 我正在使用uWSGI和Nginx制作Flask应用程序。

我的文件看起来像: wsgi.py:

from flaskapp import app
if __name__ == "__main__":
    app.run()

flaskapp.ini

[uwsgi]
limit-as = 512
module = wsgi:app
plugin = python
master = true
processes = 5
socket = flaskapp.sock
chmod-socket = 660
vacuum = true
die-on-term = true

/etc/systemd/system/flaskapp.service

[Unit]
Description=uWSGI instance to serve flaskapp
After=network.target

[Service]
User=blitwak
Group=www-data
WorkingDirectory=/home/blitwak/flaskapp
Environment="PATH=/home/blitwak/flaskapp/myprojectenv/bin"
ExecStart=/home/blitwak/flaskapp/myprojectenv/bin/uwsgi --ini flaskapp.ini

[Install]
WantedBy=multi-user.target

/etc/nginx/sites-available/flaskapp.conf

server {
    listen 80;
    server_name 162.243.76.55;

    charset utf-8;
    proxy_buffering on;
    proxy_buffer_size 1k;
    proxy_buffers 24 4k;
    proxy_busy_buffers_size 8k;
    proxy_max_temp_file_size 2048m;
    proxy_temp_file_write_size 32k;

    proxy_connect_timeout 75s;
    proxy_read_timeout 300s;


    location / {
        include uwsgi_params;
        uwsgi_pass unix:///home/blitwak/flaskapp/flaskapp.sock;

 uwsgi_param UWSGI_SCRIPT app.wsgi;

          uwsgi_buffer_size 32k;
          uwsgi_buffers 8 32k;
          uwsgi_busy_buffers_size 32k;


   }
}

并且在/var/log/nginx/error.log中它说了很多次:

  

2017/01/19 15:58:18 [错误] 19181#19181:* 36过早上游   从上游读取响应头时关闭连接,客户端:   {myip},server:{myserver},request:“POST / yajugue HTTP / 1.1”,   上游:“uwsgi:// unix:///home/blitwak/flaskapp/flaskapp.sock:”,   主持人:“{myserver}”,推荐人:“http:// {myserver} / jugarPrimeraVez”

非常感谢!!!

我该如何解决?

对于Flask应用程序可能已经设置了足够的规则。 例如:

sudo chmod 710 /var/www/flask_app 
sudo chown -R nginx: /var/www/flask_app
