[rabbitmq-discuss] rabbitmq on yocto/openembedded

Fri Feb 1 13:29:29 GMT 2013

I think that I've now got Erlang installed - 'hello world' works, anyway, and openembedded has created what looks like a sensible rpm: erlang-R15B-r3.armv5te

However, the generic unix install seems unable to get going - I get an erlang crash dump and the /var/log/rabbitmq at nodename does not tell me very much about where to look, if I start the server with rabbitmq-server (as user rabbitmq or as user root):

[code]
=INFO REPORT==== 31-Jan-2013::22:26:04 ===
Error description:
   undef

Log files (may contain more information):
   /var/log/rabbitmq/rabbit at qemuarm.log
   /var/log/rabbitmq/rabbit at qemuarm-sasl.log

Stack trace:
   [{mnesia,system_info,[directory],[]},
    {rabbit_mnesia,ensure_mnesia_dir,0,[]},
    {rabbit_node_monitor,prepare_cluster_status_files,0,[]},
    {rabbit,'-boot/0-fun-1-',0,[]},
    {rabbit,start_it,1,[]},
    {init,start_it,1,[]},
    {init,start_em,1,[]}]
[/code]

I've checked the file permissions (or got around them by running as root.)  How do I go about debugging a rabbitmq install?  Are there smoke tests for erlang/rabbit that I can try that check out the set up? or something else - the documentation that I've found so far seems to assume that I can get past this point, so I'd assume that I'm making some silly mistake somewhere.
