App Deployment: WSGI Server to go inside the Virtual ENV or installed globally?

由 感情迁移 提交于 2019-12-25 02:08:54
问题 The following question is aimed for two use cases. Use case 1: Deploying a single WSGI app on a single server. Use case 2: Deploying one or more WSGI apps on the same server. My question: Should the WSGI server be installed inside the same virtualenv along the Python WSGI application itself? or; Should I have the WSGI server installed globally? I am wondering about WSGI applications (based on frameworks) such as Flask, CherryPy, Pyramid etc. And WSGI servers such as Gunicorn, Waitress etc.

I declare a local variable (for example test ) that contains all the html code and then i put it as parameter in

由 放肆的年华 提交于 2019-12-24 19:08:57
问题 I modified beej's guide to networking example (as seen below) to pass back a html response to a browser. I am getting "The connection was reset" every few refreshes, and can't seem to figure out why? Its as if it is closing the connection before it sends out the html response. Any ideas, or suggestions to debug? Edit: It does sometimes pass the correct data to the browser. Here is the code: /* ** server.c -- a stream socket server demo */ #include <iostream> #include <string> #include <stdio

由 别来无恙 提交于 2019-12-24 13:47:13

Is one connection somehow transferred to other incoming port to be able to listen to new connection? 回答1: Even if the server IP and server port are the same, the client
