LABORATORY EXERCISES
LABORATORY EXERCISE 08: VIRTUAL HOSTING (1 HOUR)
A. SINGLE DAEMON, MULTIPLE SITES USING VIRTUAL HOST BLOCK AND A SINGLE IP ADDRESS:
Requirements:
1. Fully qualified domain name (FQDN) resolvable/mapped for each additional website/host.
2. Document Root folder and website contents for each additional host.
3. A NameVirtualHost directive should be defined
NameVirtualHost [IP Address/*]:[Port]
4. A <VirtualHost> block for each different host that you would like to serve
Procedure:
1. Your websites:
Primary/default Website FQDN: ________________________
Secondary Website FQDN: ______________________
2. Update your hosts file (/etc/hosts) to define/map the FQDNs to the server’s IP address.
Watch out: the host file (that is used for simulating the function of DNS) should define the default
FQDN of the host server. For example, your hostname is student, you may add the following line
in the hosts file:
111.111.111.1 student.<your name>.com student
3. Create a document root directory for the new host/website
Secondary Website FQDN’s Document Root directory: ______________________
4. Modify the default web page for the default webpage file. Copy/Create a default webpage file to
the Secondary Website.
5. Update the httpd.conf file to define the virtual hosts. You may follow the syntax below:
NameVirtualHost *:80
<VirtualHost *:80>
Server name Primary_FQDN
DocumentRoot Primary_DocumentRoot_folder
</VirtualHost>

Servername Secondary_FQDN
DocumentRoot Secondary_DocumentRoot_folder
