Question

I am trying to create a multi drupal site in one server. I have placed my drupal like
/var/www/html/drupal
/var/www/html/drupal01
/var/www/html/drupal02
I cant use subdomains for this appIication and i would like to access each drupal site like http://www.example.com (/var/www/html/drupal) , http://www.example.com/drupal01 (/var/www/html/drupal01)
I am able to configure my first drupal instance ie http://www.example.com. How can I try access my other drupal instances.

What you are looking for is VirtualHosts
# Ensure that Apache listens on port 80
Listen 80
<VirtualHost *:80>
DocumentRoot "/www/example1"
ServerName www.example.com
# Other directives here
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "/www/example2"
ServerName www.example2.com
# Other directives here
</VirtualHost>

The default root path of apache server in ubuntu for the domain name 'localhost' is pointed to the /var/www/html folder, that's how you can access the /var/www/html/your_project via http://localhost/your_project.
You can actually create a virtual host with a domain name of your preference (eg: your_domain) for your project folder (eg: /home/user/projects/your_project) so that you could access the project by visting the local url http://your_domain. This would require adding your domain name to /etc/hosts file and placing and enabling the virtual host configuration file which contains the domain name and the project directory path.

I have created a bash script to do this step very easily. You just
need to execute the script enter the domain name & project path and it
will create the virtual host for you.
