Interprocess messaging between two Python programs

We have two Python programs running on two linux servers. Now we want to send messages between these Python programs. The best idea so far is to create a TCP/IP server and client architecture, but this seems like a very complicate way to do it. Is this reall开发者_如何学运维y best practice for doing such a thing?

I like zeromq for simple messaging, it's really lightweight and fast...very flexible as well. Using AMQP messaging isn't a bad idea either depending on the specifics of your situation, I've found kombu to be a very nice pythonic library for that. You could also use xmlrpclib or setup a simple REST API with bottle or flask. Every option has it's place, so I'd investigate all your options.

This really depends on the kind of messaging you want and the roles of the two processes. If it's proper "client/server", I would probably create a SimpleHTTPServer and then use HTTP to communicate between the two. You can also use XMLRPCLib and the client to talk between them. Manually creating a TCP server with your own custom protocol sounds like a bad idea to me. You might also consider using a message queue system to communicate between them.

You could have a mulitprocessing.managers. As doc says :"A manager object controls a server process which manages shared objects. Other processes can access the shared objects by using proxies."

In your case, you could create a master process that control your other processes, each of those processes will call the master to grab the data.
