Installing Perl CGI in Apache (Windows platform)


How to install perl cgi in Apache webserver:
Download the latest version of ActivePerl from http://www.activestate.com/store/activeperl/download (if it asks you to register, you can just leave the form blank and hit “Continue”).

Get the Windows (x86) MSI version.
My file was named: ActivePerl-5.8.8.819-MSWin32-x86-267479.msi
Install Active Perl
On the “Setup” screen (where you choose what features to install — should be about the 2nd or 3rd screen in. 
It is highly recommend that you install perl to a directory like:
c:\usr\

In someone else’s words (very good advice) 
If you will be using Perl CGI programs and want to maintain some level of portability between both Linux machines and Windows machines, you will want to install Perl to the same location on your Windows machine that it is on most Linux machines.

For example, on a standard Linux machine, Perl is located at /usr/bin/perl and so every Perl program that I write begins with #!/usr/bin/perl. So, when I install Perl on a Windows machine, instead of installing it in the default location (which is E:\perl for ActivePerl) I install it in C:\usr so that the Perl executable is located at /usr/bin/perl. This allows me to write code on my Windows machine, then move it (without making any changes) to a Linux machine and have it run there. And vice versa. 

[Check] Add Perl to the PATH environment variable
[Check] Create Perl file extension association
The rest should be grayed out and read-only, but if not, leave them unchecked

Activating CGI:

Using Notepad (or other text editor) open
C:\Program Files\Apache2_2\conf\httpd.conf
(also should be start-menu shortcut called “Edit Apache HTTP httpd.conf File“) and search for
Options Indexes FollowSymLinks
(about line 267) when you find it add ExecCGI to the end so it looks like
Options Indexes FollowSymLinks ExecCGI

[OPTIONAL] Enabling CGI in any directory:

If you want to use CGI outside the C:/Program Files/Apache2_2/cgi-bin/ ScriptAliased directory, you will need to uncomment the following line:
#AddHandler cgi-script .cgi
becomes
AddHandler cgi-script .cgi (remove the #)
I also added .pl behind .cgi so ‘perl’ extension is also treated as cgi files.

If you will be creating your own cgi-bin, you will want to comment out:
ScriptAlias /cgi-bin/C:/Program Files/Apache2_2/cgi-bin/
so it becomes
#ScriptAlias /cgi-bin/C:/Program Files/Apache2_2/cgi-bin/

Finding your location to perl:
If you do not know where your perl.exe installed to, go to Start -> Search and type in a search for perl.exe
This location is the path to perl you put on the top of all your cgi scripts. If you listened to my advice in the “Install” step, the path should be close to: C:/usr/bin/perl.exe

Some notes  :

For the perl path C:/usr/bin/perl.exe all of these are/were valid.
I prefer the last one because of the Linux <<>> Windows portability.
#!C:/usr/bin/perl.exe
#!C:/usr/bin/perl
#!/usr/bin/perl.exe
#!/usr/bin/perl
 

Testing CGI:
If you if you uncommented (removed the # symbol) the line
AddHandler cgi-script .cgi in step #4, then create a file in your document_root called hello.cgi and put these three lines in it.
(if you did not comment/disable it, put the CGI file in C:/Program Files/Apache2_2/cgi-bin/):

#!/usr/bin/perl
print “Content-type:text/html\n\n”;
print “hello world”;
Restart Apache if it is already running.

Now go to http://localhost/cgi-bin/hello.cgi (or wherever you put the file) and run the script.
If you get a hello world in your browser, CGI is running. If you get a 500 error, go to the last entry in C:/Program Files/Apache2_2/logs/error.log (or the Review Error Log in the start menu) to see exactly what caused this error.

I think this will will help you to run perl on windows platform using apache web server.
