RabbitMQ-server won't start

[Suzi B]

Hello,

Anyone have any idea what might cause the following error when starting rabbitmq server? I'm running it in RHEL 5, erlang OTP 17.3 and rabbitmq-server 3.4.2

You probably aren't running 17.3. lists:keyfind/3 was added in R13B; I
suspect you're actually picking up Erlang R12B-something, which I think
was what was available for RHEL 5 originally.

The Erlang version gets logged at startup - what does the log message
"Starting RabbitMQ 3.4.2..." say?

Cheers, Simon

Hi Simon,

It says:

Starting rabbitmq-server: SUCCESS

rabbitmq-server.

I meant the main log - something like
/var/log/rabbitmq/rab...@somehostname.log if installed via RPM.

Cheers, Simon

Sorry, it says:

Starting RabbitMQ 3.4.2 on Erlang R12B

I checked my packages and it has erlang-R12B-5.11.el5. I deleted that since I installed 17.3 via src. When I start rabbitmq it now says:

Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}
rabbitmq-server.

In the startup_err file, it says:

/usr/lib/rabbitmq/bin/rabbitmq-server: line 50: erl: command not found

but when I enter erl in the prompt, I can execute the command.

[suzi@xxxxxx ~]$ erl 
Erlang/OTP 17 [erts-6.2] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V6.2  (abort with ^G)

Presumably this is caused by a difference in the PATH that is available
to you in an interactive session vs the system-wide one.

It sounds like you installed Erlang from source and RabbitMQ from the
RPM. This can certainly be made to work, but it's a configuration that
lots of people have problems with and we can't really provide general
Unix support on configuring paths and so on.

You may find it easiest to go back to
http://www.rabbitmq.com/install-rpm.html and follow the instructions on
getting an RPM for Erlang - the ones from Erlang Solutions are probably
best in general.

Cheers, Simon

OK. Thanks!

For future reference, I solved this by doing the following:

 

sudo ln -s /usr/local/lib/erlang/bin/erl /usr/bin/.

sudo ln -s /usr/local/lib/erlang/bin/erl /bin/.
