OpenShift-DIY-Perl

Steps to support Perl 5.16 or newer version on OpenShift.com

Steps:

Create new app using diy-0.1 cartridge:

rhc app create diyapp diy-0.1
rhc ssh -a diyapp

Download & Build new version of Perl from source:

cd ~/app-root/data/
mkdir download
cd download
wget -c -nd http://www.cpan.org/src/5.0/perl-5.16.3.tar.gz
tar -xf perl-5.16.3.tar.gz
cd perl-5.16.3
./Configure -des -Dprefix=~/app-root/data/perl-new
make 
make install
cd ~/app-root/data/perl-new/bin
./perl -v

Then install additional Perl modules:

cd ~/app-root/data/perl-new/bin
HOME=~/app-root/data/ ./perl cpan
> cpan[1]    notest install Dancer Mojolicious DBD::Pg DBD::SQLite DBD::mysql and_other_modules
> quit

Roll your own webserver

To start your own web server run on host $OPENSHIFT_INTERNAL_IP and on port $OPENSHIFT_INTERNAL_PORT (usually port 8080) :

cd ~/app-root/data/perl-new/bin
./perl morbo --listen 'http://$OPENSHIFT_INTERNAL_IP:$OPENSHIFT_INTERNAL_PORT' ~/app-root/runtime/repo/diy/mojoapp.pl

However, Please edit this file:

.openshift/action_hooks/start

to

#!/bin/bash
nohup ~/app-root/data/perl-5.16.3/bin/perl ~/app-root/data/perl-5.16.3/bin/morbo --listen 'http://$OPENSHIFT_INTERNAL_IP:$OPENSHIFT_INTERNAL_PORT' ~/app-root/runtime/repo/diy/mojoapp.pl > /dev/null  2>&1 &

to autostart your webserver.

and also:

.openshift/action_hooks/stop

to

#!/bin/bash
kill `ps -ef | grep morbo | grep -v grep | awk '{ print $2 }'` > /dev/null 2>&1
exit 0

to stop your webserver.

Test on your browser:

http://[diyapp]-[yournamespace].rhcloud.com

Maintenance

To stop/start/restart your app:

rhc ssh -a diyapp 

ctl_app stop

Remember to always stop your webserver before running git push.

rhc ssh -a diyapp
