Mojolicious, Morbo, Hypnotoad and Apache httpd deployment [SOLVED]

brilant_blue has asked for the wisdom of the Perl Monks concerning the following question:

Hello dear Monks!

I am trying to run and deploy an app I wrote in Perl and Mojolicious.

When I use Morbo development server, everything is fine, pretty, fast and simple.

But:

When I try to change Apache httpd config file httpd.conf to work with my Mojolicious app according to documentation on the Internet, all pages of the web app are not available -- 404 HTTP error.

Webpages with docs:
http://mojolicio.us/perldoc/Mojolicious/Guides
http://mojolicio.us/perldoc/Mojolicious/Guides/Cookbook
http://mojolicio.us/perldoc/Mojo/Server/Morbo
http://mojolicio.us/perldoc/Mojo/Server/Hypnotoad
https://github.com/kraih/mojo/wiki/Apache-deployment
https://github.com/kraih/mojo/wiki/Hypnotoad-prefork-web-server

Relevant part of file httpd.conf (at the end of file):

<VirtualHost *:80>
    ServerName localhost
    ProxyPass / http://localhost:8080/
    ProxyPassReverse / http://localhost:8080/
    
    <Perl>
        $ENV{PLACK_ENV} = 'production';
        $ENV{MOJO_HOME} = '/var/www/MezlApp';
        $ENV{MOJO_MODE} = 'deployment';
    </Perl>
    
    <Location />
        SetHandler perl-script
        PerlResponseHandler Plack::Handler::Apache2
        PerlSetVar psgi_app /var/www/MezlApp/script/runapp
    </Location>
</VirtualHost>
[download]

This is the last version of text in httpd.conf. After some playing with it I realized I have no idea how to deploy my app to Apache httpd server and I decided to try to play with Hypnotoad but with no positive effect yet.

When I try to run this app with Hypnotoad server:

$ cd ~

my home directory is /home/martin

$ hypnotoad PokusApp/runhtapp.pl

the command fails with this two sentences:

Deep recursion on subroutine "Mojo::Server::Hypnotoad::run" at /home/martin/PokusApp/runhtapp.pl line 7.

Deep recursion on subroutine "Mojo::Server::load_app" at /usr/share/perl5/vendor_perl/Mojo/Server/Hypnotoad.pm line 35.

File /home/martin/PokusApp/runhtapp.pl:

#!/usr/bin/perl
use strict;
use warnings;
use Mojo::Server::Hypnotoad;

my $hypnotoad = Mojo::Server::Hypnotoad->new;
$hypnotoad->run('/home/martin/PokusApp/script/runapp'); # Line 7!
[download]

File /home/martin/PokusApp/script/runapp:

#!/usr/bin/perl
use strict;
use warnings;
use FDI; # FileDirInfo

BEGIN {
    unshift @INC, "$FDI::cfd/../lib";
}

require Mojolicious::Commands;
Mojolicious::Commands->start_app('PokusApp');
[download]

Where is the bug? What I made wrong?

My operatig system is Fedora 20 i386. I use Perl v5.18.2 and Mojolicious distribution from Fedora's repository. Output of:

$ perl -MMojolicious -e "print Mojolicious->VERSION"

is:

4.25

When I run tests:

$ PokusApp/script/runapp test

All tests successful. Result: PASS

Thank you for your help.

`<Perl> $ENV{PLACK_ENV} = 'production'; $ENV{MOJO_HOME} = '/var/www/MezlApp'; $ENV{MOJO_MODE} = 'deployment'; </Perl>` [download] ~~This has no effect whatsoever; Apache won't even start a perl process for you. After all you configured a reverse proxy, not a perl launcher.~~ Update: you do seem to set up a perl launcher, but for the location as the reverse proxy. Don't do that. So, my advice: start your app the way you usually do, but use `hypnotoad` instead of `morbo` - no other changes so far. Then test the app with your browser, connecting to hypnotoad directly, not to Apache. Only when that works, you start your apache and try to ues the reverse proxy. That way you can cleanly separate debugging hypnotoad startup from the reverse proxy. Perl 6 - the future is here, just unevenly distributed	[reply] [d/l] [select]

You will inevitably find this sort of thing to be a difference between the dev tool and the actual Apache environment with regard to the Perl library search-order. The classes related to the application cannot be found. Debug the situation by close examination of server logs and/or by adding specific debugging statements to the start of your app that will cause it to tell you what it sees when it is running in the Apache (vs. dev) environments.

... runhtapp.pl ... Um, no. Hypnotoad wants apps not hypnotoads :) Try running `hypnotoad /home/martin/PokusApp/script/runapp`	[reply] [d/l]

Is that a confusing message ? Where is application class "PokusApp". located?	[reply]
