你好吗? 我在 DigitalOcean 上有一台使用 Ubuntu 16.04 的服务器 我正在使用 uWSGI 和 Nginx 制作 Flask 应用程序。
我的文件如下所示: 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

User=blitwak
Group=www-data
WorkingDirectory=/home/blitwak/flaskapp
Environment="PATH=/home/blitwak/flaskapp/myprojectenv/bin"

[Install]

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

uwsgi_param UWSGI_SCRIPT app.wsgi;
uwsgi_buffer_size 32k;
uwsgi_buffers 8 32k;
uwsgi_busy_buffers_size 32k;
}
}
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、客户端读取响应标头时关闭连接: {myip},服务器:{myserver},请求:“POST /yajugue HTTP/1.1”, 上游:“uwsgi://unix:///home/blitwak/flaskapp/flaskapp.sock:”, 主机:“{myserver}”,引用者:“http://{myserver}/jugarPrimeraVez”
非常感谢!!!
如何解决?
也许为 Flask 应用程序设置了足够的规则。 例如:
sudo chmod 710 /var/www/flask_app
sudo chown -R nginx: /var/www/flask_app
