Setup RabbitMQ plugins

Description:
I am attempting to add the RabbitMQ Management plugin to my newly setup Azure Bitnami configuration on a Linux VM.

I am executing the statement: sbin/rabbitmq-plugins enable rabbitmq_management

This is giving me the error: {:cannot_write_enabled_plugins_file, "/opt/bitnami/rabbitmq/etc/rabbitmq/enabled_plugins", :eacces}

I read a bit about this in a github post:abbitmq-server won't be able to read a RABBITMQ_ENABLED_PLUGINS_FILE it created if umask is strict #1129. At the end it says: I strongly recommend people who want to run RabbitMQ in a particularly strict environment to use their deployment tools to set the permissions and umask to their needs instead of expecting our packages to cater to every possible case: sometimes their needs are on the opposite ends of the usability/security spectrum.

I'm NOT a Linux guru, so I don't understand everything in this post! I have had to change permissions on some files to get to this point, but am unclear as to how to proceed from this point. Current permissions on this file is currently 777, so don't know what else I can do.

Suggestions?

Hello @sjreed,

I was able to enable it by running the following commands in a clean installation:

sudo /opt/bitnami/use_rabbitmq 

/opt/bitnami/rabbitmq/sbin/rabbitmq-plugins enable rabbitmq_management
    The following plugins have been configured:
      rabbitmq_management
      rabbitmq_management_agent
      rabbitmq_web_dispatch
    Applying plugin configuration to rabbitmq@localhost...
    Plugin configuration unchanged.

Note that firstly I loaded the environment variables with sudo /opt/bitnami/use_rabbitmq. Could you retry with these steps?

David,

Thank you for your prompt response!

Unfortunately, my installation does not have the use_rabbitmq file!

This installation was created on Azure through the Azure Marketplace. After working with Bitnami a while yesterday it appears I should have installed through the Bitnami interface. I wish there was a way to link the VM I have established through Azure into that interface!

However, after a while I determined that the management plugin was enabled! This even though it told me I was unable to write to the file.

So I’m able to use RabbitMQ.

Thanks…Steve

Hello @sjreed,

Thanks for letting us know. We are glad you make it work.

The main purpose of this script for RabbitMQ is to add installation binaries to the PATH as below:

PATH="/opt/bitnami/erlang/bin:/opt/bitnami/common/bin:$PATH"

We use this script to avoid interfering with the system, so these routes will be only added to the PATH when you load it. This would be the full script content:

#!/bin/sh
PATH="/opt/bitnami/erlang/bin:/opt/bitnami/common/bin:$PATH"
BITNAMI_ROOT="/opt/bitnami"
export BITNAMI_ROOT
exec /bin/bash --noprofile --norc

Regards
