Is there a minimal message queue?

I'm searching for a minimal message queue project.

With minimal I mean something along this:

• No/Minimal setup / administration
• Uses http (so I don't need protocol/开发者_运维知识库queue specific libraries/code)
• (Persistence would get extra points ;)
• (It should run on linux.)

Is there such a project available? I once heard about a message queue utilizing HTTP as the procotocol layer, but I was unable to find it.

httpsqs (HTTP Simple Queue Service, message queue based on HTTP GET/POST protocol) is probably the tool you're looking for.

I haven't had the chance to try it, but its feature set seems to meet your requirements.
