Installing Perl and Apache on Windows

1 Install perl

Download and install the latest version of ActivePerl from ActiveState.

Download and install the latest version of Apache 2.2 for Windows.

Save http://perl.apache.org/docs/2.0/os/win32/mpinstall as mpinstall.pl on your system.
Execute mpinstall.pl from a command shell window and answer the questions - it will do its best to locate Apache on your server, but you may need to provide it with a pathname if you have installed in a non-standard location.
(If you prefer not to run third-party scripts, follow the step-by-step instructions at http://perl.apache.org/docs/2.0/os/win32/install.html#PPM_Packages.)

If Apache is running, stop it (Start->Programs->Apache HTTP Server->Control Apache Server->Stop).
(You may wish to make a backup of your httpd.conf file before making any changes.)
Edit httpd.conf (Start->Programs->Apache HTTP Server->Configure Apache Server->Edit the Apache httpd.conf Configuration File, or conf/httpd.conf in your Apache installation directory).
Find the section "Dynamic Shared Object (DSO) Support", which should have a set of LoadModule directives. in it
At the end of the LoadModule directives, add the lines

LoadFile "C:/Perl/bin/perl58.dll" LoadModule perl_module modules/mod_perl.so
(If you have installed Perl somewhere other than C:/Perl then you will need to change the LoadFile directive to point to the correct location for perl58.dll.)
Test your changes (Start->Programs->Apache HTTP Server->Configure Apache Server->Test Configuration).

Start Apache (Start->Programs->Apache HTTP Server->Control Apache Server->Start).
Go to http://localhost/.
You should see the Apache 'splash page' if Apache is working properly.
Do not proceed unless Apache is working.
