Bug 7844 - plack intranet tooling for developers

koha.psgi example and plackup.sh script to run any Koha site

intranet or opac interface under plack with optional multi-process

Starman server

  plackup.sh site-name [intranet]

site-name is used to find config /etc/koha/sites/site-name/koha-conf.xml

All configuration is specified in koha.psgi, which you are welcomed to edit

and tune according to your development needs.

When you are happy with it, rename it to site name and save it for safe-keeping.

Test scenario:

1. install plack and dependencies, using ./cpanm-install.pl

2. start ./plackup.sh sitename

3. open intranet page http://localhost:5001/cgi-bin/koha/mainpage.pl

   and verify that it works

4. start ./plackup.sh sitename i[ntranet]

5. open OPAC http://localhost:5000/cgi-bin/koha/opac-main.pl

   and verify that it works

6. next step is to take a look into koha.psgi and enable additional

   debug modules, save file and reload page (plackup will reload

   code automatically)
