需要关闭python socket /在我的开发环境中找到当前正在运行的服务器

问题描述

我试图学习Python（使用Flask微框架），我很困惑，因为在我的代码中的某个地方，我保持服务器打开，我相信。

真的有两个问题。

第一：如何找到活动的连接/套接字并将其关闭？

这是一个文件应用程序（减去一个配置文件和静态内容），所以我可以发布的代码，如果需要的话。

改变）：

$ $ p $ / Development / flask_projects / test_email / env / bin / python /Development/flask_projects/test_email/app.py
*运行于http://127.0.0.1:5000/
Traceback（最近的最后一次调用）：
在<第58行中的Development / flask_projects / test_email / app.py文件;模块>
app.run（）
文件Development / flask_projects / wtchn_email / env / lib / python2.7 / site-packages / Flask-0.8-py2.7.egg / flask / app.py，第703行，运行

test_socket.bind（（hostname，port））
文件/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2 （self._sock，name）（* args）
socket.error：[Errno 48]已经在使用的地址


解决方案

如果使用linux，则可以使用 lsof 要找出哪个进程正在使用给定的端口，你可能需要先安装它，但用法很简单：

  lsof -i：5000 
  

I'm trying to learn python (using the Flask micro-framework) and I am confused because somewhere in my code i'm keeping the server open I believe.

I spin up my server with 'python app.py' and then close it however.... it still lives!

I'm not sure how this is possible but i must have done something wrong with a connection.

There are two questions here really.

First: How can I find the active connection/socket and close it

Second: Is there a way I can diagnose what is having an open connection, my hunch is that sqlLite is not closing as it is the last thing I implemented.

This is a one file application (minus a config file and static content) so I can post the code if required.

解决方案

If you use linux you can use lsof to find out which process is using a given port, you might have to install it first though, usage is pretty simple:

lsof -i :5000
