How to remove Rabbitmq so I can reinstall

Question

I was having trouble, so I went into the registry and removed the service entry for rabbitmq. Now when I try to reinstall it says it already exists but it doesn't start (since I removed it) and I can do a sc delete rabbitmq. How do I totally remove all traces of it and reinstall from scratch? I guess it exists somewhere and the registry entry is all that is gone and the install program says it us just updating it when I do the rabbitmq-service install. I tried rabbitmq-service remove but it says it doesn't exist.

Answer 1

I would suggest as follows:

sudo apt-get remove --auto-remove rabbitmq-server
sudo apt-get purge --auto-remove rabbitmq-server

It will uninstall rabbitmq and purge all data (users, vhost..)

Answer 2

RabbitMQ writes the service information into HKEY_LOCAL_MACHINE\SOFTWARE\Ericsson\Erlang\ErlSrv\1.1\RabbitMQ

To remove RabbitMQ manually you have to:

• remove the key HKEY_LOCAL_MACHINE\SOFTWARE\Ericsson\Erlang\ErlSrv\1.1\RabbitMQ
• remove the directory C:\Users\%USERNAME%\AppData\Roaming\RabbitMQ
• remove the installation-folder.

Next time I suggest to use the rabbitmq-service.bat command to install and remove the service.

you have to execute it as administrator
