Port 5671 is not listening on RabbitMQ servers after 2.0.4 upgrade

Products

• VMware RabbitMQ

Issue/Introduction

You upgraded your platform, including Ops Manager, TAS tile, 3and RabbitMQ.

Product versions:

• Ops Manager 2.10
• TAS for VMs 2.11.3
• RabbitMQ 2.0.4

After the upgrade they discovered that clients can't connect to RabbitMQ over 5671. We verified 5671 is not listening on RabbitMQ nodes. 

Environment

Product Version: 2.0

Resolution

Customer imported custom configuration in the rabbitmq advanced configuration field. This overwrote the SSL options (keys, etc.) in the new tile. Config was decoded, edited to remove SSL options / listener settings, imported, and changes applied.

1. Copy advanced config from tile.

2. Paste into file in a Linux environment.

cat file | base64 -d > new_file

3. Edit new_file to remove references to SSL options and listeners.

4. Encode new config:

cat new_file | base64 -e > new_file_encoded

5. Remove \r\n (end-of-line characters) so that whole config is a single line.

6, Copy contents of new_file_encoded, paste into advanced options for RabbitMQ tile.

7. Run Apply Changes.

The following is an example of a custom config. For this procedure, while editing the config we removed lines 7-10, starting with the line "{ssl_listeners, [5671]},".

1. [
