not sure why my rabbitmq 3.7.4. does not take new config (non erlang) format.

[htang]

Hi, I have a problem to start RabbitMQ server with the new configuration format.  I have searched issue discussion history here and could not find the post for this issue.  I wonder what if I missed or did wrong.  Here is the environments I used:

CentOS 7

Following RabbitMQ 3.7 install documentation to install erlang and RabbitMQ using following packages: erlang-20.2.2-1.el7.centos.x86_64.rpm & rabbitmq-server-3.7.4-1.el7.noarch.rpm

after installation, start rabbitmq server successfully before making any configurations (rabbit-env.conf and rabbitmq.config).

Now add new configuration files in /etc/rabbitmq folder, make sure the owner are rabbitmq and it can be read by all users with these files, the rabbitmq.config file is as following

cluster_formation.classic_config.nodes.1 = rabbit@sdt1

cluster_formation.classic_config.nodes.2 = rabbit@sdt1

cluster_formation.node_type = disc

listeners.tcp.default = 5672

loopback_users.guest = false

default_permissions.configure = .*

default_permissions.read = .*

default_permissions.write = .*

default_user_tags.administrator = true

when I start the server, get the following error:

Apr 21 23:24:22 sdt1.corp.com rabbitmq-server[21522]: {"could not start kernel pid",application_controller,"error in config file \"/etc/rabbitmq/rabbitmq.config\" (none): no ending <dot> found"}

Apr 21 23:24:23 sdt1.corp.com rabbitmq-server[21522]: could not start kernel pid (application_controller) (error in config file "/etc/rabbitmq/rabbitmq.config" (none): no ending <dot> found)

I know this is complaining that the rabbitmq.config is not using the old erlang format.

when I change the rabbitmq.config to follwoing for a test, it starts ok without problem.

[{rabbit,        [

                 {cluster_nodes, {['rabbit@sdt1', 'rabbit@sdt1'], disc}},

                 {default_user,<<"mqtttest">>},

                 {default_pass,<<"mqtttest">>},

                 {loopback_users, []},

                 {tcp_listeners,    [5672]}]}

].

Can someone tell me what I could be missing?  I thought RabbitMQ 3.7.4 definitely supports the new format. How do I debug to find out what I could do wrong?

BTW: I checked the erlang installed package, I only have the right erlang package installed as below. This is "Zero-dependency Erlang from RabbitMQ" following Michael Klishin's github repository....

[root@sdt1 rabbitmq]# yum list installed | grep erlang

erlang.x86_64                        20.2.2-1.el7.centos         installed

Thanks in advance for any help!

The message provides a hint: `rabbitmq.config` must be a valid Erlang terms file which must end with a trailing dot.

The new config format by definition doesn't have a trailing dot. So the file name must be `rabbitmq.conf`, not `rabbitmq.config`.

Hi, Mike,

 Thanks for the help, that works, after changing the file name to rabbitmq.conf, it starts fine.
