Hi, I'm trying to install rabbitmq-server on ubuntu Server 16.04 as:

apt-get install rabbitmq-server -y

during installation I'm getting error:

May 30 06:27:26 v systemd[1]: Starting RabbitMQ Messaging Server...

sudo rabbitmqctl status saying:

Error: unable to connect to node rabbit@v: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@v]

rabbit@v:
  * connected to epmd (port 4369) on v
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on v
  * suggestion: start the node

current node details:
- node name: 'rabbitmq-cli-32749@v'
- home dir: /var/lib/rabbitmq
- cookie hash: KHRxM68AKD22OGcXr68lyQ==

It's a real server for testing our application. If I'm installing rabbitmq in virtualbox also on ubuntu server 16.04 everything ok.

Can anybody help with it?

See server logs [1] and redirects of stdout and stderr that the Debian package stores in the same directory (IIRC).

Also no details were provided about what RabbitMQ version is used, what repository it is provisioned from,

what Erlang versions is used and so on. Please help others help you. We don't guess on this list.

thank you for your reply, I installed rabbitmq as sudo apt-get install rabbitmq-server,

it writing version: "RabbitMQ 3.5.7",

erlang looks like 18.3:

$ cat /usr/lib/erlang/releases/18/OTP_VERSION

showing 18.3

$ rabbitmqctl environment:
Crash dump is being written to: erl_crash.dump...done

What is in server logs? Is there *anything* else that CLI tools output? If the erl_crash.dump is the only

clue there is (it is almost never the case), can at the very least it be uploaded?

I do not provide any kind of 1-on-1 support. Please CC the list.

> bash: fork: Cannot allocate memory

is pretty unambiguous: the runtime cannot start (fork) a subprocess.

How much memory does the VM in question have available and free? (as in `free -m`)

log files are empty,

root@v:~# cat /var/log/rabbitmq/startup_err

root@v:~# cat /var/log/rabbitmq/startup_log

I even don't know how to find other logs, rabbitmqctl environment hangs my terminal and shows Cannot allocate memory

Log file location is documented [1]. The kernel has a number of log files used by different tools and subsystems under /var/log. There are tools [4] that will collect all of them into a single tarball.

If there are no logs then the node didn't have a chance to start at all

or failed very early on. The fork failure message from the shell is definitely suspicious.

1G is plenty of RAM for a RabbitMQ node but there can be other system limits and tools

such as SELinux that can prevent a process from doing much.

3.5.x is out of any kind of support, so in order to continue getting

help on this list please move to installing a 3.7.x version [2] with a compatible Erlang/OTP one [3].

epmd is not the Erlang runtime, it's a port mapping daemon used by Erlang nodes

and CLI tools for discovery. Erlang VM processes are named "beam".
