Making RabbitMQ independent of hostname of system

[badrira...@gmail.com]

Hi Luke,

   In the process of Making RabbitMQ independent of hostname of system, I am using the below steps provided by you and it is working fine. However due to some limitations, I want to avoid the Step3 that is writing fixedhost in hosts file.

Can you please suggest if there is any other way to achieve the same by skipping the Step3 ? 

Steps :

======

Step 1 : Stopping RabbitMQ service

                   .\rabbitmq-service.bat stop

Step 2: Removing RabbitMQ service

                   .\rabbitmq-service.bat remove

Step 3: Renaming RabbitMQ cluster node. NOTE: fixedhost is in            C:\Windows\System32\drivers\etc\hosts at this point

Step 4: Rename cluster command

          .\rabbitmqctl.bat rename_cluster_node rabbit@WIN81 rabbit@fixedhost

Step 5: Moving RabbitMQ data directories

           move %AppData%\RabbitMQ\db\rabbit@WIN81-mnesia  %AppData%\RabbitMQ\db\rabbit@fixedhost-mnesia

           move %AppData%\RabbitMQ\db\rabbit@WIN81-plugins-expand %AppData%\RabbitMQ\db\rabbit@fixedhost-plugins-expand

Step 6: Creating custom configuration file for NODENAME

                          vim %AppData%\RabbitMQ\rabbitmq-env-conf.bat

Step 7: Re-install RabbitMQ service

                       .\rabbitmq-service.bat install

                        .\rabbitmq-service.bat start

Thanks & Regards,

Badri.

Hello,

Your RabbitMQ host name (the part after the "@" sign) must resolve in DNS somehow. The easiest way is to write it to the hosts file. You could also use real DNS to do it. Finally, I think you can use the "inetrc" feature of the Erlang VM to set a host name / IP address but I have never tried:

https://erlang.org/doc/apps/erts/inet_cfg.html

You would configure RabbitMQ to use your file by creating the %AppData%\RabbitMQ\rabbitmq-env-conf.bat file with this content:

set SERVER_ADDITIONAL_ERL_ARGS=C:/path/to/erl_inetrc

Then, follow the re-installation procedure.

Thanks,

Luke
