If I install passenger via tarball and install it, how do I uninstall it?

Question

Normally I would install phusion passenger via the gem command, but this wouldn't work for me, so I had to install it via a tarball and then run the installer.

My question is, how do I uninstall it?

dpkg -l | grep passenger

doesn't return anything. When I list the installed gems, I don't see anything either.

So i guess I have two questions 1) If installed by tarball/installer, how to uninstall 2) If I came upon this system, how could I even tell that passenger is installed? It doesn't seem to show up anywhere?

Answer 1

You just remove the folder it was installed to, and thats it.

Answer 2

You should read what the Passenger documentation has to say about removal.

The only guaranteed indicator of a passenger installation is the passenger file in the apache configuration. Usually /etc/apache2/conf.d/passenger. You must remove it, and then uninstall passenger in a method dependent on how it was installed.

If installed from a gem:

# gem uninstall passenger

If installed from a tarball:

remove the installation directory, Which is noted as the PassengerRoot directive in the aforementioned configuration file.

If installed form a deb file:

# sudo apt-get remove libapache2-mod-passenger
