The New and Old Config File Formats

[vineeth mohan]

Hi,

I am trying to implement Cluster Formation and Peer Discovery in Rabbitmq. I have enabled the plugin 'rabbitmq_peer_discovery_aws'.

Now I wanted to modify the rabbitmq.config file to add the below settings. I am using the config file with Old Config File Formats, but the below is in New format I think. How can I include the below setting in my config file. PLease can someone help?

cluster_formation.peer_discovery_backend = rabbit_peer_discovery_aws

cluster_formation.aws.region = us-xxxx-2

cluster_formation.aws.access_key_id = someaccesskey

cluster_formation.aws.secret_key = randomsecretkey

cluster_formation.aws.use_autoscaling_group = true

Hi Vineeth,

I'm assuming that you're using a recent version of RabbitMQ (3.7.X).

If you have a mix of old-style and new configuration settings you should do the following:

* Save the configuration you posted below to /etc/rabbitmq/rabbitmq.conf

* Rename /etc/rabbitmq/rabbitmq.config to /etc/rabbitmq/advanced.config

* Restart RabbitMQ

Please check the startup log messages to ensure that RabbitMQ is reading both of the above configuration files.

Thanks,

Luke

It would be much easier to recommend something specific if you posted actual file names and their contents, and any paths used

with RABBITMQ_CONFIG_FILE and such.

You cannot put new style configuration in rabbitmq.config. The file must be named rabbitmq.conf [1].

If you want to add some settings on top in the classic config format, use advanced.config (which is an additional file to rabbitmq.conf).
