Introduction:
Hosting multiple websites on a single web server is called a virtual host. But in Nginx, the concept is called Server blocks that use the server_name and listen to directives to bind to TCP sockets. Also in certain scenarios, if you don’t want to edit the default Nginx files you can set up a virtual host to avoid editing the default configuration file.
A visual explanation of the virtual host is given below in the image:

Prerequisites:
Ubuntu server
Domain name
Map ubuntu server public IP to the domain name’s DNS.
Steps:
Step 1: Link (map) your domain name with the Ubuntu server IP.
Check out this tutorial, to link (map) your newly purchased domain name with the ubuntu server.
Step 2: Install Nginx on Ubuntu.
Check out this tutorial, to install Nginx on Ubuntu.
Step 3: Create an Nginx config file under /etc/nginx/sites-available.
Create a new file with your domain name under /etc/nginx/sites-available
1cd /etc/nginx/sites-available
2vim <Domain_Name>
3
4For example:
5vim iternerays.com
Add the following content to the file, this
Note:* Change <Domain_Name> with your domain name (for example: iternerays.com)
1server {
2 listen 80;
3 listen [::]:80;
4
5 server_name <Domain_Name>;
6
7 root /var/www/<Domain_Name>;
8 index index.html;
9
10 location / {
11 try_files $uri $uri/ =404;
12 }
13}
The sample domain configuration file link given below.

Step 4: Create a symbolic link under /etc/nginx/sites-enabled/.
Create a symbolic link from sites-available to sites-enabled
1sudo ln -s /etc/nginx/sites-available/<Domain_Name> /etc/nginx/sites-enabled/
2
3For example:
4sudo ln -s /etc/nginx/sites-available/iternerays.com /etc/nginx/sites-enabled/
After executing the command a symbolic link will be created. An example output screenshot is given below:
Step 5: Create a root directory under /var/www for the virtual host.
Create a directory under /var/www with the domain name.
1cd /var/www
2mkdir <Domain_Name>
3
4For example:
5mkdir iternarys.com
Navigate to the domain directory created above step.
1cd /var/www/<Domain_Name>
2
3For example:
4cd /var/www/iternarys.com
Create index.html under your domain directory (i.e /var/www/<Domain_Name>)
1touch index.html
2echo"<h1>Hello World</h1>" >> index.html
Restart Nginx
1sudo systemctl restart nginx
Result:
check your browser, by visiting your domain name (for example: iternerays.com ). The reference output screenshot is given below.
