Dancer2 - Deployment

Premises:
- That a Perl-enable environment on the PC with a 'myexample' folder - which, via an FTP client (eg.FileZilla), is synchronized with the 'myexample' folder on the server.
- Both PC and Server have tested, via http on port:5000 by running the command [plackup -p 5000 bin/app.psgi] within its main directory (myexample/) then visit localhost:5000 or http://[MySeverIP]:5000
- That the service; myexample.service is actively serving port:8080
- [Optional]Nginx Webserver is serving iRedmail app, http://[MySeverIP]/mail

Strategy

To have first create a website SSL certificate via Let'sEncrypt - see SSL Certificate for Websites Thereafter [optional] if Nginx is serving iRedmail, the port serving its mail apps will need to be changed from 443 to 8443. The Dancer2 will then be service by Apache2, ultimately on port 443 with a LetsEncrypt certificate.

Set Apache2 to host the Dancer2 site

Assumption: Apache2 installed and active such it shows its default page at http://[MySeverIP]

Ex2a: Apache2-Native-Perl-Configuration (Preferred)
Requires: mod_perl plus Plack::Handler::Apache2

sammy@imega:sudo apt -y install libapache2-mod-perl2
sammy@imega:sudo a2enmod perl // engaging/disengaging Apache2 modules can done in Webmin: Servers->Apache2->global configuration -> modules sammy@imega:$ sudo perl -MCPAN -e shell
sammy@imega:$ sudo install Plack::Handler::Apache2
sammy@imega:$ exit // engaging Perl modules moreover can done in Webmin: Tools-> Perl Modules-> Install modules

Via Webmin: Servers->Apache2, create a new host use the following configuration provided here: Apache2-Dancer2-Config-Plack.txt

sammy@imega:sudo systemctl restart apache2

Thereafter open the browser with http://myexample.com. Your 3-page Dancer website should appear.

Reference: Dancer2-Deployment

Secondly, replace the contents of the index.html found at /var/www/htm/ with the following this text: port80-referral-port443.txt (using your own domain). Thereafter all links to your domain will call on port 443 and will render the website.

Note: In initial attempts of Apache2 to render the Dancer2 website, there maybe some links to the Perl modules that are appear missing. Check the Apache2 error log at Webmin: Tools-> System-> System Logs and view the entries. Install the missing modules via Webmin: Tools-> Perl Modules-> Install modules.

Set Nginx to serve iRedmail port:8443

Note: The firewall requires adjustment to allow port:8443 to be exposed.

Via Webmin: Servers->Nginx->Existing Virtual Host and disable the two default hosts. Create this third host: myexample.com.conf

Restart Nginx and thereafter iRedmail apps can be accessed at http://[MySeverIP]or myexample:8443/mail or /iredadmin
