[Technical tips] EB-336x Series Install Debian 11 and Build Nginx Web Server

This article will show you how to Build a Nginx Web Server under Debian 11.

What is Nginx?

Nginx is an open source web server that can be used for a variety of web services, including HTTP servers, reverse proxy servers, mail proxy servers, etc. Nginx was designed to handle the demands of highly concurrent, high-traffic web services.

A computer is responsible for delivering web pages, mainly constructed in various programming languages, to a client (usually a web browser) via the Hypertext Transfer Protocol (HTTP).
A server program that provides web pages.

Nginx Server installation

Step1: Reboot EBOX with internet connected, then enter Debian 11 desktop

Click terminal and Install Nginx Server by executing command
Run command:
```
$sudo apt update
```
```
$sudo apt upgrade
```
To install Nginx server, execute
Run command:
```
$sudo apt install nginx
```
By default, the Nginx server will start on Debian 11 and it can be verified with the netstat command/ss command and ps command

Run command:

$ ps aux | grep nginx

$ pgrep nginx

$ sudo apt install net-tools

Use the netstat command as follows to verify if port 80 is open
Run command:
```
$ netstat -tulpn | grep :80
```

Step2: Test the Nginx Sever

Open up a web browser and type url: http://your-domain/
Or find the public IP address using the ip/ifconfig Run command:
```
$ ip a
```
Open web broswer and enter http://your-domain/ or your IP address directly.
Enter IP address: http://192.168.4.174
If you see below page, the nginx web server is successfully installed and working.

Step3: Configure Nginx Server
In Nginx, all HTML, CSS and Image files are stored by default in the /var/www/html directory, known as the web server's root. The default directory can be modified in the /etc/nginx/sites-enabled/default config file. User can edit it with nano command.

Execute following vim command/nano command to setting the web server default file
Run Command:
```
$ sudo nano /etc/nginx/sites-enabled/default
```
The /etc/nginx/nginx.conf is your main nginx config file and /etc/nginx/sites-enabled/default is the default config file.
To create a Virtual Host named “dmpdemo”, execute:

Run command:

$ sudo nano /etc/nginx/sites-available/dmpdemo

Input the code below in “dmpdemo”:

server {
listen 80;
listen [::]:80;
server_name dmpdemo;
root /home/dmp/www;
index index.html;
location / {
try_files $uri $uri/ =404;
}
}

Let the file synchronize with:

Run command:

$ sudo ln -s /etc/nginx/sites-available/dmpdemo /etc/nginx/sites-enabled/

Remove the default file with:

Run command:

$ sudo rm /etc/nginx/sites-enabled/default

Remove the default file with:

Run command:

$ sudo rm /etc/nginx/sites-enabled/default

Establish the path for the web page location and create the webpage.

Run command:

$ sudo mkdir ~/www

$ sudo nano ~/www/index.html

Type the following website code to the index.html:

<!DOCTYPE html>
<html>
<head>
<title>Welcome to Icop Tech</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>
<h1>Welcome to ICOP Tech</h1>
<p>This is a test for Nginx web server.</p>
 
<p><em>Hello world.</em></p>
</body>
</html>

Press “Ctrl + O” to Write Out and “Ctrl +X” to exit; Reload Nginx server and re-start browser.
Run command:
```
$ sudo systemctl reload nginx
```

Enter the IP address to display the web page (~/www/index.html) from the Nginx web server. Web page is now successfully created!
