Understanding Virtual Host Server Name in Relaxed English Language

Welcome Dev, do you want to create multiple websites or host client websites, but you only have a single server? This dilemma can be resolved with the use of Virtual Host Server Name, and In this article, we will cover all the vital information about this amazing technology.

What is a Virtual Host Server Name?

A Virtual Host Server Name, also known as Virtual Host, is a technique that allows the hosting of multiple websites on a single server. It utilizes the HTTP/1.1 protocol, which enables the webserver to identify the requested domain and assign it to the corresponding web directory.

The Virtual Host Server Name provides a cost-effective solution for web hosting companies that want to offer affordable hosting services to their clients. This technology also helps in the efficient use of resources, as the server is utilized optimally by hosting multiple websites.

How Does Virtual Host Server Name work?

When a user requests a website, the web browser sends a request to the server with the domain name. The HTTP/1.1 protocol uses the Host header field to identify the requested domain name. The web server then searches for the domain name in its configuration files and assigns it to the corresponding web directory.

Table 1: Virtual Host Server Name Sample Configuration
Server Name	Web Directory
www.example.com	/var/www/example.com/public_html/
www.anotherexample.com	/var/www/anotherexample.com/public_html/

In the above configuration, when a user requests www.example.com, the webserver will assign the request to the /var/www/example.com/public_html/ directory.

Advantages of using a Virtual Host Server Name

There are several benefits of using a Virtual Host Server Name:

• Cost-effective solution for hosting multiple websites
• Efficient use of server resources
• Provides better security as each website is isolated from the other
• Facilitates the use of SSL certificates for each domain

Disadvantages of using a Virtual Host Server Name

There are also some limitations of using a Virtual Host Server Name:

• Performance issues may arise if the server is hosting too many websites
• If one website on the server is compromised, all other websites on the server are also at risk
• If the server goes down, all websites hosted on the server become unavailable

Setting up a Virtual Host Server Name

Setting up a Virtual Host Server Name requires the following:

• A server with Apache webserver installed
• The configuration files of Apache webserver
• The DNS records pointing to the server IP address

Step 1: Configuring the Apache Webserver

The first step in setting up a Virtual Host Server Name is to configure the Apache webserver. This involves creating a new configuration file for each domain that needs to be hosted on the server.

The configuration file for each domain should contain the following:

• The ServerName directive, which specifies the domain name
• The DocumentRoot directive, which specifies the path to the web directory

Here’s an example of a configuration file for www.example.com:

<VirtualHost *:80>ServerName www.example.comDocumentRoot /var/www/example.com/public_html/</VirtualHost>

Step 2: Creating the Web Directory

The next step is to create the web directory for each domain that needs to be hosted on the server. This is where the website files will be stored.

Here’s an example of how to create a web directory for www.example.com:

sudo mkdir -p /var/www/example.com/public_htmlsudo chown -R $USER:$USER /var/www/example.com/public_htmlsudo chmod -R 755 /var/www/example.com

Step 3: Editing the Hosts File

The Hosts file is a local file on your computer that maps domain names to IP addresses. Editing this file allows your computer to access the server using the domain name.

To edit the Hosts file on Windows:

• Open Notepad as an administrator
• Click File > Open
• Change the file type to All Files (*.*)
• Navigate to C:\Windows\System32\drivers\etc
• Open the hosts file
• Add the following line at the end of the file: server_ip_address www.example.com

To edit the Hosts file on Linux:

• Open the terminal
• Type sudo nano /etc/hosts
• Add the following line at the end of the file: server_ip_address www.example.com
• Save and close the file
