如何通信两个单独的python进程? [英] how to communicate two separate python processes?

问题描述

我有两个python程序，我想与他们交流.
它们都是系统服务，并且都不是由父进程派生的.

I have two python programs and I want to communicate them.
Both of them are system services and none of them is forked by parent process.

有没有不使用套接字的方法吗?
(例如，创建一些Queue->序列化->由其他进程反序列化并执行通信；或在要执行通信的文件上写入进程ID，然后创建获取进程ID并向该进程发送一些消息的魔术结构... )

Is there any way to do this without using sockets?
(eg by crating some Queue -> serialize it -> deserialize by other process and perform communication; or write on file process id to which perform communication, and then create magic structure which gets process id and send some messages to this process... )

该解决方案应可在Linux和Windows上运行.

The solution should work on Linux and Windows.

推荐答案

您最好的选择是 ZeroMQ ，是专为IPC设计的，并且使用IPC的速度非常快(还支持TCP/多播消息传递). Python绑定非常好，并且易于使用.此处对Python的ZeroMQ进行了很好的介绍: http://nichol.as/zeromq-an-introduction .如果您打算将其扩展到多台机器上，那么AMQP(这是一个消息队列协议)将是一个不错的选择，有很多很棒的库可用于AMQP for python.我真的很喜欢 kombu 和扭曲，它为您提供了相当疯狂的通信选项，并且提供了一个不错的事件循环启动.

Your best bet is ZeroMQ, which is designed for, and extremely fast at IPC (also supports TCP/multicast messaging as well). The Python bindings are really nice, and easy to work with. There is a nice introduction to ZeroMQ with Python here: http://nichol.as/zeromq-an-introduction. If you were planning to expand this across multiple machines, AMQP (which is a message queue protocol) would be a good to look at, there are a lot of great libraries for working with AMQP for python. I really like kombu and celery. You could also think about twisted, which gives you a fairly insane number of options for communication, and a nice event loop to boot.
