Phusion passenger-status: what value for passenger_instance_registry_dir?

Question

I\'ve done a new install of nginx 1.6.3 and passenger 5.0.15 on Ubuntu 14.04 from source in order to add tracing components from AppNeta for my ROR 4.2 app on one of my serv

Passenger author here.

/tmp/passenger.JxmCeiA is an example of an instance directory. This changes indeed with every startup (because it is specific to an instance).

The parent directory (the directory in which instance directories are located) is the instance registry directory. So in your case, the instance registry directory that is being used is /tmp.

I'm guessing that you have some kind of Passenger installation version mismatch. We've changed the structure of the instance directory a few times in the past, and every time we did this we bump an internal version number to indicate that it's incompatible with previous Passenger versions. Can you double check the following?

• Does Passenger appear to be otherwise running correctly?
• What Passenger version is compiled inside Nginx?
• What is your passenger_root set to? Does it match the Passenger version compiled inside Nginx?
• Where is the full path to the first passenger-status in PATH? Does it match passenger_root?

You also seem to be mixing the Phusion Passenger APT repository with source tarball install. Having multiple installations around is generally a bad idea. Try cleaning up your other installs so that you only end up with one.

Also check whether you are setting the PASSENGER_INSTANCE_REGISTRY_DIR environment variable correctly. Note that sudo nukes environment variables, so you need to run passenger-status like this:

# Correct:
sudo env PASSENGER_INSTANCE_REGISTRY_DIR=/tmp passenger-status

# Incorrect, sudo nukes environment variables
export PASSENGER_INSTANCE_REGISTRY_DIR=/tmp
sudo passenger-status

Regarding lib/phusion_passenger/nginx/config_options.rb: that file mainly lists per-server and per-location config options. Many config options in the main context are either not yet ported to the config_options.rb system, or not possible because they require custom attention. At present, passenger_instance_registry_dir is implemented in ext/common/nginx/Configuration.c. As we continue to cleanup and refactor the codebase, this option may eventually be moved to config_options.rb.
