NGINX,uWSGI和Flask没有运行子进程

我的NGINX配置:

server {
  server_name 127.0.0.1;
  listen 4450;
  location ~* ^/.*$ {
  include uwsgi_params;
    uwsgi_pass unix:/tmp/esrvadmin.sock;
  }
}
uWSGI启动:

uwsgi --uid root -s /tmp/esrvadmin.sock --chown-socket nobody:root \
  --file /var/www/sitios/manten/srv.py \
  --processes 2 --callable app --pidfile /var/run/edesarrollos/esrvadmin.pid

带烧瓶代码的Python:

import os, subprocess
from flask import Flask, abort, request
app = Flask(__name__)

DETO_DIR = '/var/www/sitios/manten/detos'

@app.route('/detonate')
def index():
  #return str(subprocess.check_output(['ls','-l']))
  token = request.args.get('token','')
  if token != '':
     # Si no existe el directorio de detonatores, se crea
     if not os.path.exists(DETO_DIR):
       os.mkdir(DETO_DIR)
     if os.path.isfile(DETO_DIR+"/"+token):
       try:
         os.system(open(DETO_DIR+"/"+token).read())
       except Exception as ex:
         return str(ex)
       return "Reiniciado Correctamente"
     else:
       abort(404) 
  else:
    abort(404)

if __name__ == "__main__":
    app.run(debug=True,host='0.0.0.0')

模式下,我可以运行os.system(“something args”)内的任何内容并接收其HTTP响应,即使“service something start”也可以完成。我也试过子进程函数,没有运气。

但是当我从NGINX-uWSGI运行时,我得到一个永远等待的http请求,当然从来没有响应,但它完成了工作(启动服务)。

我发现日志中的最佳错误说明:

2013/01/28 03:38:24 [error] 3978#0: *3 upstream timed out (110: Connection timed out) 
while reading response header from upstream, client:

知道会发生什么事吗?
