Hello,

RabbitMQ : 3.6.0
OS : Redhat 6.x
Erlang : 18.1

When I want to start RabbitMQ server, I get the following error :

{
    error_logger, {

        }, {

Your config cannot be loaded and the reason seems fairly unusual. I recall seeing
this when config file was passed using RABBITMQ_SERVER_ERL_ARGS or
RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS and there were missing
arguments and/or shell quoting issues.

Hi,

Looks like there are errors when loading config file. Can you check /home/rabbitmq/etc/rabbitmq/rabbitmq.config file to exist, be valid and accessible for user, starting server?

It will be also good to know RabbitMQ version, way you installed server and how do you run it.

Hi,

The RabbitMQ server version is 3.6.0.
The /home/rabbitmq/etc/rabbitmq/rabbitmq.config file exists. The file has the right owners properties.

I start the server with the following command : rabbitmq-server -detached

All environment variables are exported.

Hi,

Here is my rabbitmq.config file.

Hi,

Looks like there are some error in erlang command arguments. Like there are two values of '-config' arguments ("/home/rabbitmq/etc/rabbitmq/rabbitmq" and "1048576").

Can you tell what distribution do you use?

I used the binary file (rabbitmq_server-3.6.0.tar.xz)

It is most likely env variable problem. Please check variables mentioned above.

You can also check RABBITMQ_CONFIG_FILE and CONFIG_FILE variables.

Or you can edit sbin/rabbitmq-server script and add 'echo' to print erlang execution command (line 103, right after start_rabbitmq_server() )

Hi,

Ok. There are RABBITMQ_IO_THREAD_POOL_SIZE env variable, which is missing for some reason. By default it is set from IO_THREAD_POOL_SIZE variable, which should be set in rabbitmq-defaults file.

Hi,

I added the RABBITMQ_IO_THREAD_POOL_SIZE env variable with value 30.
Here is the erl_crash.dump content :

Slogan: init terminating in do_boot ()
System version: Erlang/OTP 18 [erts-7.1] [source] [64-bit] [smp:2:2] [async-threads:30] [hipe] [kernel-poll:true]

If I start the server without the option "-detached", I receive the following error :

{"init terminating in do_boot",{undef,[{boot,start,[],[]},{init,start_it,1,[]},{init,start_em,1,[]}]}}

Looks like you missing entire rabbitmq-defaults file, where lot of env variable defaults is defined.

Can you look for it in your rabbitmq installation (it should be in sbin directory)?

It is loaded from RABBITMQ_SCRIPTS_DIR, maybe this variable is wrong for some reason.

Before starting the server, all env variables are exported :
Here is the list :

RABBITMQ_HOME
RABBITMQ_INSTANCE_HOME

RABBITMQ_MANAGEMENT_PORT
RABBITMQ_DIST_PORT

RABBITMQ_NODENAME
RABBITMQ_USE_LONGNAME
RABBITMQ_MNESIA_BASE
RABBITMQ_MNESIA_DIR
RABBITMQ_LOG_BASE
RABBITMQ_LOGS
RABBITMQ_SASL_LOGS
RABBITMQ_CONFIG_FILE
RABBITMQ_EBIN_ROOT
RABBITMQ_PLUGINS_DIR
RABBITMQ_PLUGINS_EXPAND_DIR
RABBITMQ_ENABLED_PLUGINS_FILE
RABBITMQ_PID_FILE
RABBITMQ_IO_THREAD_POOL_SIZE

ERL_DIR
ERL_EPMD_PORT

The rabbitmq-defaults is present in the folder sbin

What do you mean by 'exported'?

And what is the values of this variables?

I mean that before launching the server, a script is executed to set the value of the variables and to export them.

The content of the variables :

RABBITMQ_HOME="$HOME"
RABBITMQ_INSTANCE_HOME="$HOME"

RABBITMQ_MANAGEMENT_PORT=15672
RABBITMQ_DIST_PORT=25672

RABBITMQ_NODENAME=rabbit@$HOSTNAME
RABBITMQ_USE_LONGNAME=true
RABBITMQ_MNESIA_BASE=$RABBITMQ_HOME/var/lib/rabbitmq/mnesia
RABBITMQ_MNESIA_DIR=$RABBITMQ_MNESIA_BASE/rabbitmq
RABBITMQ_LOG_BASE=$RABBITMQ_HOME/logs
RABBITMQ_LOGS=$RABBITMQ_LOG_BASE/rabbitmq.log
RABBITMQ_SASL_LOGS=$RABBITMQ_LOG_BASE/rabbitmq-sasl.log
RABBITMQ_CONFIG_FILE=$RABBITMQ_HOME/etc/rabbitmq/rabbitmq
RABBITMQ_EBIN_ROOT=$RABBITMQ_HOME/ebin
RABBITMQ_PLUGINS_DIR=$RABBITMQ_HOME/plugins
RABBITMQ_PLUGINS_EXPAND_DIR=$RABBITMQ_MNESIA_BASE/rabbitmq-plugins-expand
RABBITMQ_ENABLED_PLUGINS_FILE=$RABBITMQ_HOME/etc/rabbitmq/enabled_plugins
RABBITMQ_PID_FILE=$RABBITMQ_MNESIA_DIR.pid
RABBITMQ_IO_THREAD_POOL_SIZE=30

ERL_EPMD_PORT=12222
ERL_EPMD_RELAXED_COMMAND_CHECK="TRUE"

RABBITMQ_NODE_PORT=5672

So you have script, which is something like this:

. env.sh
/home/rabbitmq/sbin/rabbitmq-server

While env.sh contain specified env variables.

Your installation is in /home/rabbitmq

And you have files /home/rabbitmq/sbin/rabbitmq-defaults and /home/rabbitmq/sbin/rabbitmq-env

Is that correct?

Yes, the installation is in /home/rabbitmq
In /home/rabbitmq/sbin/ folder, I have the following files

The scripts to start and stop RabbitMQ are in the bin folder.

If you start rabbitmq-server directly, without exporting variables, does it run?
