When you uninstall the Tentacle MSI, it automatically removes the application files from the installation folder, but that's it. This page describes how to manually clean up Tentacle in part, or completely remove it from your server.
Why would I want to clean up in the first place?
In some of these scenarios you should make sure you have a recent backup of the Tentacle Home Directory before continuing. If you want to completely remove this instance of Tentacle and don't care about the configuration, applications or data, you won't need to worry about having a backup or rollback strategy.
Here are a few reasons why you may want to completely remove Tentacle from your computer:
- You are moving this server's responsilibities to another server and want to clean up Tentacle after the move is completed.
- You installed a trial of Octopus Server and want to completely uninstall the trial Tentacle instance from your computer now that you've finished your trial.
- You are having communication problems with this Tentacle and want to try completly uninstalling and reconfiguring the Tentacle as part of the troubleshooting process. This can happen if your Tentacle installation was corrupted somehow.
Just upgraded from Octopus Deploy 2.6 and want to clean up?
If you have just completed an in-place upgrade from Octopus Server 2.6 to 3.x there will be several folders and files left over that aren't used by newer versions of Tentacle. We didn't remove these files in case you needed to roll back. Learn about cleaning up after upgrading from Octopus 2.6.
What does the Tentacle MSI actually do?
The MSI will stop the Tentacle windows service and remove the application files which are normally stored in your
%ProgramFiles% folder. The MSI will leave all of the configuration required to run Tentacle just like before you run the uninstaller. The installer behaves this way because the makes it easier for you to upgrade the application files for Tentacle knowing your configuration, data, and applications preserved.
