Uninstalling Passenger Enterprise + Apache

Uninstalling Passenger Enterprise involves two steps. The first step is to remove the Passenger files. The second step is to remove any Passenger configuration from your system.

Step 1: remove the Passenger files

Removing the Passenger files depends on how you installed Passenger.

If Passenger is installed as follows... ...then do this
Phusion's APT repository for Debian/Ubuntu
sudo apt-get remove -y passenger-enterprise libapache2-mod-passenger-enterprise
Phusion's YUM repository for Red Hat/CentOS
sudo yum remove -y passenger-enterprise mod_passenger_enterprise
Ruby gem
gem uninstall passenger-enterprise-server
Source tarball Remove the directory in which you placed the extracted Passenger files. This directory is the same as the one pointed to by the PassengerRoot configuration directive.

Step 2: remove Passenger configuration from system

Inspect all your Apache configuration files, and remove any Passenger-related configuration options.

If you installed Passenger via a source tarball, then edit your shell startup file (e.g. /etc/bashrc) and ensure the Passenger bin directory is no longer in PATH.
