Install Apache2 webserver with PERL,Php Support in Ubuntu Server(verified and tested)

Install Apache2 in Ubuntu

sudo aptitude install apache2

This will complete the installation.

After installation
Type the server’s IP address (or alias if you added the server to your /etc/hosts file) in your browser’s address bar or, if you are browsing on the server itself, type 127.0.0.1 or localhost. If an error occurs, then you will have to edit the apache2.conf file to ensure that Apache can fully resolve the server’s name.If you have any problem then you have to edit the apache2 configuration file using the following command

sudo nano /etc/apache2/apache2.conf
Add the following line somewhere
ServerName localhost
or
ServerName yourserverip
Save and exit the file

Restart Apache server using the following command.
sudo apache2ctl restart

Change default document root in Apache2
The main configuration file located at /etc/apache2/apche2.conf.If you want to change the default document root you need to edit the /etc/apache2/sites-available/default file and look for this line “DocumentRoot /var/www/” here you can change where ever you want to change.For example if you want to change /home/www the above line looks like this “DocumentRoot /home/www/”.
Save and exit the file

Restart Apache server using the following command.
sudo apache2ctl restart




Enable CGI and perl support for apache2 server
You need to install the following package

sudo aptitude install libapache2-mod-perl2

Configure a cgi-bin directory
You need to create a cgi-bin directory using the following command
sudo mkdir /home/www/cgi-bin
Configuring Apache to allow CGI program execution is pretty easy. Create a directory to be used for CGI programs and add the following to the site configuration file (again between the <VirtualHost> tags).

ScriptAlias /cgi-bin/ /home/www/cgi-bin/
<Directory /home/www/cgi-bin/>
Options ExecCGI
 AddHandler cgi-script cgi pl

       AddHandler default-handler .jpg .png .gif .js .txt .bat .css .html .htm

</Directory>

The first line creates an alias that points to the directory in which CGI scripts are stored. The final line tells Apache that only files that end with the *.cgi and *.pl extensions should be considered CGI programs and executed.

**AddHandler default-handler .jpg .png .gif .js .txt .bat .css .html .htm
this tells cgi to exclude some of the non perl related files like "CSS,txt,html etc"

Test your Perl Program
cd /home/www/cgi-bin
sudo nano perltest.pl
Copy and paste the following section save and exit the file.

###Start###
#!/usr/bin/perl -w
print "Content-type: text/html\r\n\r\n";
print "Hello there!<br />\nJust testing .<br />\n";

Change permissions on it

sudo chmod a+x perltest.pl
Open your web browser open
http://yourserverip/cgi-bin/perltest.pl.It should be working.
