Dreamhost Web2py (Python) deployment issue

[Samuel Sowah]

I followed instructions given me here for deploying web2py on dreamhost. I didn't encounter any errors at any step of the way, but when I tried opening the web page at my domain, it just keeps loading forever, then all of a sudden a web application could not be started page slaps me in the face. I get this message at the top of the page

An error occurred while starting the web application: it did not write a startup response in time. Please read this article for more information about this problem.

Raw process output:

!> Ready
!> socket: main;unix:/tmp/passenger.1.0.22131/generation-1/backends/wsgi.17327;session;1
!> 

what could be the problem and how do i resolve it?

How does your passenger_wsgi.py look like?

This line is the problem. This was a hack used in the Phusion
Passenger 3 days to ensure that your app is run under a specific
Python interpreter. We no longer support this hack in Phusion
Passenger 4, and the official way to run your app under a specific
Python interpreter is by using the PassengerPython config option.

[Samuel Sowah]

How do I fix that?

[Hongli Lai]

As I've stated, you need to use the PassengerPython config option. Set
it in your Apache configuration file. Here is the documentation for
that option: https://www.phusionpassenger.com/documentation/Users%20guide%20Apache.html#_passengerpython_lt_filename_gt

Did you remove any *.pyc files on the server? Otherwise your change
might not be picked up.

I removed the passenger_wsgi.pyc file, edited the PassengerPython in my httpd.conf file to "PassengerPython python"

<IfModule mod_passenger.c>

PassengerEnabled Off

PassengerRoot /dh/passenger

PassengerMaxPoolSize 4

PassengerPoolIdleTime 1200

PassengerMaxPreloaderIdleTime 3600

PassengerMaxInstancesPerApp 2

PassengerMaxRequests 400

PassengerRuby /usr/bin/ruby1.8

PassengerPython python

</IfModule>

same result

!> Ready
!> socket: main;unix:/tmp/passenger.1.0.29231/generation-0/backends/wsgi.5541;session;1
!> 

is there another way?

P.S I tried both PassengerEnabled Off and PassengerEnabled On

[Hongli Lai]

Not 'PassengerPython python'. In your old code with the INTERP command, you were specifically trying to use /home/myusername/env/web2py-env/bin/python2.7 as Python interpreter. So you need to specify 'PassengerPython /home/myusername/env/web2py-env/bin/python2.7'.
