RabbitMQ 3.8.4 fails to load rabbitmq.conf after service reinstall

[walker...@gmail.com]

Hello, 

I just recently noticed this - we're trying to upgrade our RabbitMQ from 3.8.2 to 3.8.4. 

After service reinstall, it fails to load the rabbitmq.conf correctly. 

It uses the advanced.config (which is empty - we don't use this) instead. 

And so I tried to use the environment variable RABBITMQ_CONFIG_FILE to force the RabbitMQ to use rabbitmq.conf but I've encountered these messages instead - and the service won't start.

We were able to use the RABBITMQ_CONFIG_FILE system environment variable before. Did something change? 

Here's the setup I'm running RabbitMQ with:
OS: Windows 10 Pro

RabbitMQ: 3.8.4

Erlang: 10.7 (OTP  22.3)

* All ports needed by Erlang and RabbitMQ are set up

Hi,

The very first item on 3.8.5 release notes says "In 3.8.4, RABBITMQ_CONF_ENV_FILE value was ignored on Windows." :)

Best regards,

Hello,

Unfortunately I can't read that screenshot. Please save a larger format and attach it as a file, not in-line.

In addition, attach all of the complete configuration files you are trying to use, and share the exact commands you are using to upgrade.

Thanks,

Luke

Have you tried 3.8.5? As I mentioned, there was a bug in 3.8.4 which led to RABBITMQ_CONF_ENV_FILE being ignored on Windows. 3.8.5 fixed that.

PS 3.8.6 was just released if you want.

Hello Luke, 

I attached the configuration file I'm currently using - rabbitmq.conf. 

So what I did was - 

Prerequisite: 

1. Uninstalled RabbitMQ 3.8.2
2. Uninstalled Erlang 10.5
3. Performed 'clean-up' like delete the installation artifacts, delete the erlang.cookie files, delete the RabbitMQ app data folder.

Installation/Service Reinstall:

1. Upgraded my Erlang to 22.3
2. I downloaded 3.8.4 from GitHub, and installed it to my machine.
3. Then to have RabbitMQ load our own rabbitmq.conf, I did the service reinstall 
1. rabbitmq-service stop
2. rabbitmq-service remove
3. rabbitmq-service install
4. Doing #3 somehow killed the service - I did all the troubleshooting I knew - like checked .erlang.cookie files if they are in sync, checked ports... everything seemed to be fine, except that RabbitMQ refused to start. (Please see the attached file - AfterServiceReinstall.jpg)

I wanted to attach the erlang crash dump, but I think it exceeded attachment file size limit but I uploaded it in my drive here - 

https://drive.google.com/file/d/1B-jPfEBPtSfjrEQ2EEg0L7F-ZFMalXQd/view?usp=sharing

I also attached here the rabbitmq log.

Dev environment: 

• OS: Windows 10 Pro 
• RabbitMQ: 3.8.4
• Erlang: 10.7

Best regards,

Hello Michal, 

Yes I've tried 3.8.5 and 3.8.6. 

I get the same results. 

Erlang crashes - RabbitMQ service won't start. 

I get the same erlang crash dump.

Hello Luke, 

I had to delete my previous reply because I mistakenly uploaded something else.

Hello,

In the log file you provided you can see that something told RabbitMQ to stop:

2020-08-04 19:49:26.056 [info] <0.713.0> Server startup complete; 0 plugins started.

2020-08-04 19:56:06.249 [info] <0.92.0> RabbitMQ is asked to stop...

2020-08-04 19:56:06.328 [info] <0.92.0> Stopping RabbitMQ applications and their dependencies in the following order:

It appears there was a graceful shutdown?

First, remove all traces of RabbitMQ 3.8.4 and install version 3.8.6 that was just released - https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.8.6

Could you please stop the Windows service, if running, and open an administrative prompt. Navigate to this directory...

C:\Program Files\RabbitMQ Server\rabbitmq_server-3.8.6\sbin

...and run these commands:

set LOG=debug

.\rabbitmq-server.bat

This will run RabbitMQ in the foreground and we may get more information.

Thanks,

Luke

Hello Luke, 

I did what you suggested. It works now for some reason. 

I'm now using RMQ 3.8.6 and Erlang OTP 23. 

Thank you very much for your help. 

Best regards, 

Renya W.
