I've installed a brace of Couchbase 2.0 servers, and all is well and good, so far. Now I'm looking to add RabbitMQ.
RabbitMQ also depends on Erlang. The path to a vendor-supported version (like Couchbase Enterprise) is via VMware vFabric, which yields rabbitmq-server v2.86 and erlang R15B. So, before I start installing, I thought I would ask:
(1) am I going to run into a problem running two versions of erlang on the same server? (port conflicts, version conflicts)
(2) is it possible (or even a good idea) to use a single version of erlang? The version that Couchbase uses is embedded in the install, and doesn't create or fill any install-time (read: yum, apt) dependencies.
At some point I'm actually going to try this, so if nothing else, I'll post my results here. Just thought I'd ask, first.
