Mojolicious::Guides::Cookbook - Cookbook
Cooking with Mojolicious, recipes for every taste.
Getting Mojolicious and Mojolicious::Lite applications running on different platforms.
Mojolicious contains a very portable HTTP 1.1 compliant web server. It is usally used during development but is solid and fast enough for small to mid sized applications.
% ./script/myapp daemon Server available at http://127.0.0.1:3000.
It has many configuration options and is known to work on every platform Perl works on.
% ./script/myapp help daemon ...List of available options...
Another huge advantage is that it supports TLS and WebSockets out of the box.
% ./script/myapp daemon --listen https://*:3000 Server available at https://*:3000.
A development certificate for testing purposes is built right in, so it just works.
CGI is supported out of the box and your Mojolicious application will automatically detect that it is executed as a CGI script.
CGI
<VirtualHost *:80> ServerName localhost DocumentRoot /home/sri/myapp/public ScriptAlias /myapp "/home/sri/myapp/script/myapp" </VirtualHost>
FastCGI is also supported out of the box and your Mojolicious application will automatically detect that it is executed as a FastCGI script.
FastCGI
<VirtualHost *:80> ServerName localhost DocumentRoot /home/sri/myapp/public FastCgiServer /home/sri/myapp/script/myapp -processes 10 Alias /myapp /home/sri/myapp/script/myapp </VirtualHost>
PSGI is an interface between Perl web frameworks and web servers, and Plack is a Perl module and toolkit that contains PSGI middleware, helpers and adapters to web servers. PSGI and Plack are inspired by Python's WSGI and Ruby's Rack. Mojolicious applications are ridiculously simple to deploy with Plack.
% plackup ./script/myapp HTTP::Server::PSGI: Accepting connections at http://0:5000/
Plack provides many server and protocol adapters for you to choose from such as FCGI, SCGI and mod_perl. Make sure to run plackup from your applications home directory, otherwise libraries might not be found.
FCGI
SCGI
mod_perl
plackup
% plackup ./script/myapp -s FCGI -l /tmp/myapp.sock
Because plackup uses a weird trick to load your script, Mojolicious is not always able to detect the applications home directory, if thats the case you can simply use the MOJO_HOME environment variable. Also note that app->start needs to be the last Perl statement in the application script for the same reason.
MOJO_HOME
app->start
% MOJO_HOME=/home/sri/myapp plackup ./script/myapp HTTP::Server::PSGI: Accepting connections at http://0:5000/
Some server adapters might ask for a .psgi file, if thats the case you can just point them at your application script because it will automatically act like one if it detects the presence of a PLACK_ENV environment variable.
.psgi
PLACK_ENV
mod_perl is a good example for a PSGI adapter that is used without plackup, note that setting the PLACK_ENV environment variable is required for Mojolicious PSGI detection.
<VirtualHost *:80> ServerName localhost DocumentRoot /home/sri/myapp/public <Perl> $ENV{PLACK_ENV} = 'production'; $ENV{MOJO_HOME} = '/home/sri/myapp'; </Perl> <Location /myapp> SetHandler perl-script PerlHandler Plack::Handler::Apache2 PerlSetVar psgi_app /home/sri/myapp/script/myapp </Location> </VirtualHost>
We don't suggest using IIS, it is a horribly broken web server, avoid it if you can. There is nothing we can do to make this a pleasant experience for you, but maybe we can at least ease some of the pain.
First you should make sure to get recent versions of Strawberry Perl and Mojolicious installed, Strawberry is as good as a Windows version of Perl can be.

Then you'll have to install IIS 6.0 and its FastCGI extension, which is not part of the standard installation. Create a new website with Control Panel > Administrative Tools > Internet Information Services Manager > Action > New > Web Site and finish the installation wizard.

Web Site
Open your newly created websites properties and select the tab Web Site. Set the proper values for Site Description, IP Address, TCP Port, SSL Port etc.
Site Description

On the tab Home Directory set Local Path to c:\myapp\public, Local Path Permission Flags to Read and Log Visits, Execute Permissions to Scripts Only.

Click on the Configuration button and then Insert (next to Wildcard Application Mappings). In the next dialog set Executable to c:\windows\system32\inetsrv\fcgiext.dll and uncheck Verify That Files Exist.

Now put the following lines into c:\windows\system32\inetsrv\fcgiext.ini or c:\windows\syswow64\inetsrv\fcgiext.ini on 64-bit systems.

There is one more thing, IIS sometimes clears your environment variables but Windows won't work without SYSTEMROOT, so you might have to set it manually in your application.
SYSTEMROOT
# Application package MyApp; use base 'Mojolicious'; sub startup { my $self = shift; # Use event hook to set environment variable for every request $self->hook( before_dispatch => sub { $ENV{SYSTEMROOT} = 'c:\\winnt' } ); } 1;
Hacks that might not be very useful but are fun! :)
If every byte matters this is the smallest Hello World application you can write with Mojolicious::Lite.
Hello World
use Mojolicious::Lite; get '/' => {text => 'Hello World!'}; app->start;
It works because automatic rendering kicks in even if no actual code gets executed by the router, the renderer just picks up the text value from the stash and generates a response.

To install Mojolicious, copy and paste the appropriate command in to your terminal.
cpanm
cpanm Mojolicious
CPAN shell
perl -MCPAN -e shell install Mojolicious
