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
带有烧瓶代码的 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')
在主模式下,我可以在 os.system("something args") 中运行任何东西并接收它的 HTTP 响应,即使使用“服务启动”并且它正确完成。我也尝试了子进程功能,但没有运气。
但是当我从 NGINX-uWSGI 运行时,我得到一个永远等待的 http 请求,当然永远不会响应,但它完成了工作(启动服务)。
我发现日志中最好的错误描述:
2013/01/28 03:38:24 [error] 3978#0: *3 upstream timed out (110: Connection timed out)
while reading response header from upstream, client:

知道会发生什么吗?
