Question

这是我第一次处理flask / uwsgi。我遵循以下指南： https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-uwsgi-and-nginx-on-ubuntu-16-04

*仅尝试在uwsgi下不进行烧瓶开发的情况下效果很好。

运行uwsgi服务器的命令：

uwsgi --socket 0.0.0.0:5007 --protocol=http -w wsgi:app --enable-threads

我的应用程序是多线程的，运行没有gui的chrome-selenium：

from flask import Flask, request
from flask_restful import Resource, Api
import queue
import threading
...
threadList = ['111', '222']
queueLock = threading.Lock()
workQueue = queue.Queue(10)
threads = []
threadID = 1

# Create new threads
for tName in threadList:
    thread = myThread(threadID, tName, workQueue)
    thread.start()
    threads.append(thread)
    threadID += 1
    sleep(5)
app = Flask(__name__)
api = Api(app)
api.add_resource(user_info, '/userinfo')  # Route_3

if __name__ == '__main__':
    app.run(host='0.0.0.0', port='5007')

# Notify threads it's time to exit
exitFlag = 1

# Wait for all threads to complete
for t in threads:
   t.join()
print ("Exiting Main Thread")

应用程序启动良好，但是线程无故停止。 uwsgi日志：

flask和uwsgi下的线程化python应用程序。失败
