How can I find Phusion Passenger version?

Question

How can I find my Phusion Passenger version? is there a command i can run from the terminal?

Solution 1

locate passenger-config
/path/to/passenger-config --version

Or try searching your system's package manager if Passenger was installed from a package

Solution 2

You can use the following command to find out the current version:

passenger -v

Solution 3

try

passenger-config --version

Solution 4

If installed from apt-get, you can't get passenger -v from a command line, however you could get from package manager:

dpkg -l | grep passenger

Which will return something like:

ii  libapache2-mod-passenger      3.0.13debian-1  amd64  Rails and Rack support for Apache2

You can than grab the version number from this with your favourite regex command.

You can find where your passenger command is stored, as it might not be in your path, by doing: gem contents passenger | grep passenger$

It says: cannot load such file -- phusion_passenger. I installed passenger from official repository.

Additional note, this command only works in the repository where you have installed passenger if passenger is not globally installed.
