How to Install Apache2 webserver with PHP,CGI and Perl Support in Ubuntu Server
Sponsored Link
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
Now you need to 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
Now you need to restart Apache server using the following command.
sudo apache2ctl restart
Enable PHP support for apache2 webserver
If you want to enable php5 or php4 support to your apache webserver use the following commands to install require packages
For PHP5
sudo aptitiude install php5 libapache2-mod-php5
For PHP4
sudo aptitiude install php4 libapache2-mod-php4
You also make sure the php5 and php4 modules are enabled using the following commands
sudo a2enmod php5
sudo a2enmod php4
After installing php support you need to restart apache webserver using the following command
sudo apache2ctl restart
Test your PHP Support foe apache webserver
To check the status of your PHP installation
sudo nano /var/www/testphp.php
and insert the following line
<?php phpinfo(); ?>
Save and exit the file
Now open web browser at http://yourserveripaddress/testphp.php and check.
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
</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.
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";for ($i=0; $i<10; $i++)
{
print $i."<br />";
}###End###
make sure you change permissions on it
sudo chmod a+x perltest.pl
Now open your web browser open http://yourserverip/cgi-bin/perltest.pl.It should be working.
To use aptitude you need aptitude installed, if not just use apt-get
I try to install cgi in my Ubuntu 11.04. I put testperl.pl in /usr/lib/cgi-bin. So, how we can access it from the browser?
I try to access with http://localhost/cgi-bin
but, it can’t work. could you help me??
Hi.
I see that makin programs for cgi-bin eather is a php script with .php extention og perl with .pl
Is it possible to make programs without any exstention?
…. if …. howto?
Fixed – Working on new Ubuntu
Where is site configuration file….???
On Ubuntu 12.04, it wasn’t working for no apparent reason. Everything seemed set up correctly. So I ran:
aptitude reinstall libapache2-mod-php5 php5-common
/etc/init.d/apache2 restart
And now it works.
/etc/apache2/sites-available/default
use:
gksudo gedit /etc/apache2/sites-available/default
to edit the file.
Thanx. Was really helpful.
I guess it saved me a lot of time 🙂
Good article and i was able to configure PERL and PHP in my Ubuntu laptop system.
Thanks, i couldn’t remember how i did it last time.
hey…. im having trouble with the location of /cgi-bin/
permission denied.
and cant run perl file too…. help please?
Hey i was trying the same on myserver IP ,
where
when i tried to install
sudo pt-get install libapache2-mod-perl2
it show error message :Unable to locate package libapache2-mod-perl2
please suggest
it is :
sudo apt-get install libapache2-mod-perl2
This is for the Perl CGI PL
I did everything exactly what the article said, but when i execute it at localhost/cgi-bin/perltest.pl firefox starts to prompt with a download box. It is not executing it but it is downloading. Why is it downloading, i already restarted my PC, configured my apache2.conf @ /etc/apache2/, Why firefox is downloading it? Please respond Thanks.
I follow your step But error has occur. any one help me .error is -> The requested URL /cgi-bin/test.pl was not found on this server.
after googling…
you have to execute “sudo a2enmod cgi” to configure apache2 and module cgi
and “sudo apache2ctl restart”
so you don’t need to insert “ScriptAlias ……” and “<Directory….."
only you have to use /usr/lib/cgi-bin/ and save here your perl script.
at last in your pearl.pl script you have to write ONLY:
#!/usr/bin/perl -w
print "Content-type: text/html\r\n\r\n";
print "Hello there!\nJust testing .\n”;
for ($i=0; $i<10; $i++)
{
print $i."”;
}
remember to leave a blank row after #!/usr….
and it will work!!
