A single Drupal installation can host multiple Drupal sites, each with its own configuration. Additional sites are created by copying the default directory and modifying the settings.php file. Each site can have its own modules and themes directories. A Drupal multisite allows for easy updating, testing new distributions, and setting up sandboxes by hosting multiple sites from a single Drupal install.

MULTISITE CONFIGURATION
-----------------------
A single Drupal installation can host several Drupal-powered sites, each
with its own individual configuration.
Additional site configurations are created in subdirectories within the 'sites'
directory. Each subdirectory must have a 'settings.php' file, which
specifies
the configuration settings. The easiest way to create additional sites is to
copy the 'default' directory and modify the 'settings.php' file as appropriate.
The new directory name is constructed from the site's URL. The
configuration for www.example.com could be in
'sites/example.com/settings.php' (note that 'www.' should be omitted if
users can access your site at http://example.com/).

3. Sites do not have to have a different domain. You can also use
subdomains and subdirectories for Drupal sites. For example,
example.com, sub.example.com, and sub.example.com/site3 can all be
defined as independent Drupal sites. The setup for a configuration such
as this would look like the following:
sites/default/settings.php
sites/example.com/settings.php
sites/sub.example.com/settings.php
sites/sub.example.com.site3/settings.php
When searching for a site configuration (for example
www.sub.example.com/site3), Drupal will search for configuration files
in the following order, using the first configuration it finds:
Drupal MultiSites

4. sites/www.sub.example.com.site3/settings.php
sites/sub.example.com.site3/settings.php
sites/example.com.site3/settings.php
sites/www.sub.example.com/settings.php
sites/sub.example.com/settings.php
sites/example.com/settings.php
sites/default/settings.php
If you are installing on a non-standard port, the port number is treated as
the deepest subdomain. For example: http://www.example.com:8080/
could be loaded from sites/8080.www.example.com/. The port number
will be removed according to the pattern above if no port-specific
configuration is found, just like a real subdomain.

5. Each site configuration can have its own site-specific modules and themes in
addition to those installed in the standard 'modules' and 'themes' directories.
To use site-specific modules or themes, simply create a 'modules' or 'themes'
directory within the site configuration directory. For example, if
sub.example.com has a custom theme and a custom module that should not
be accessible to other sites, the setup would look like this:
sites/sub.example.com/
settings.php
themes/custom_theme
modules/custom_module

settings, consult http://drupal.org/getting-started/6/install/multi-site

configuration, see step 6 above.

12. Webserver
A computer software that could
make available data, info, files
for downloading by a web
browser, another computer
software.

13. Webserver
Tim Berners-Lee invented the first web
server software.

14. Webserver
Apache is
the most
used
webserver

15. Webserver
Webservers
most of the
time run in
Linux
machines.

16. Webserver
XAMPP is one
of the most
popular
portable
webserver
package.

20. Virtual Host
Advantages
●
Freedom to try out different domain names
●
Freedom to designate any folder as
DocumentRoot
●
Freedom to designate as many folder as
DocumentRoot

21. Virtual Host in XAMPP
1.“httpd-vhosts.conf” found in
Windows=>C:xamppapacheconfextra
Linux=>/opt/lampp/etc/extra/
2.“hosts” found in
Windows=>C:WindowsSystem32driversetc
Linux=>/etc/
Files to Edit

22. Virtual Host in XAMPP
NameVirtualHost *:80
<VirtualHost *:80>
DocumentRoot "C:/xampp/htdocs"
ServerName localhost
</VirtualHost>
httpd-vhosts.conf
Comment out (#) all the default text in the file and Input the following
right after the last commented line (#).

23. Virtual Host in XAMPP
<VirtualHost *:80>
DocumentRoot "C:Documents and SettingsjunabejoMy DocumentsDemosites"
ServerName demo.local
ServerAlias *.demo.local
<Directory "C:Documents and SettingsjunabejoMy DocumentsDemosites">
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Allow from all
Require all granted
</Directory>
</VirtualHost>
httpd-vhosts.conf
Then, Input the following ...

24. Virtual Host in XAMPP
127.0.0.1 localhost
127.0.0.1 domainname.loc
127.0.0.1 domainname.local
127.0.0.1 domainname.dev
127.0.0.1 domainname.ass
127.0.0.1 domainname.build
127.0.0.1 subdomain1.domainname.loc

127.0.0.1 subdomain4.domainname.loc
127.0.0.1 subdomain5.domainname.loc
127.0.0.1 subdomain6.domainname.loc
hosts
Edit hosts file by adding all the local subdomain names you wanted to setup.
Examples of site names are as follows....

25. Virtual Host in XAMPP
After editing httpd-vhosts.conf and/or hosts,
restart webserver

26. ●
Extract one Drupal package in your “DocumentRoot” of
the Virtual Host
●
Copy and rename “default” folder found in “sites” folder to
names of your local site-names
●
Change permission of “default” folder to writable by all or
chmod 777.
●
Read instructions in example.sites.php
●
Rename example.sites.php to sites.php
●
Edit accordingly sites.php
●
Input in sites.php all the site-names and aliases.
