Install Nginx
To install Nginx on Ubuntu 22.10, follow these steps:
Step 1 : Update the package index:

Configuration Nginx
To add a new configuration to Nginx and have it enabled, you can create a new configuration file in the /etc/nginx/sites-available directory and then create a symbolic link to it in the /etc/nginx/sites-enabled directory. Here's the step-by-step process:
Step 6 : Create a new configuration file for your site in the /etc/nginx/sites-available directory:
sudo nano /etc/nginx/sites-available/example.com
Replace example.com with the name of your domain.
Step 7 : Add the following server block to the configuration file:
server {
listen 80;
server_name example.com;
root /var/www/example.com;
index index.html;
location / {
try_files $uri $uri/ =404;
}
}
Replace example.com with the name of your domain and /var/www/example.com with the path to the root directory for the website.
Step 8 : Save the file and close it.
Step 9 : Create a symbolic link to the configuration file in the /etc/nginx/sites-enabled directory:
sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/
Replace example.com with the name of your domain.
Step 10 : Verify that the Nginx configuration is correct:
sudo nginx -t
Step 11 : If the configuration is correct, reload Nginx to apply the changes:
sudo systemctl reload nginx
Step 12 : If necessary, create the root directory for the domain:
sudo mkdir /var/www/example.com
Replace /var/www/example.com with the path to the root directory for the website.
Step 13 : Create an HTML file in the domain's root directory:
sudo nano /var/www/example.com/index.html
Step 14 : Add the following HTML code to the file:
<html>
<head>
<title>Example Domain</title>
</head>
<body>
<h1>Welcome to Example Domain</h1>
<p>This is a sample HTML page for the domain example.com.</p>
</body>
</html>
Step 1, You can access the page by visiting : https://example.com/
Generate Let's Encrypt SSL
To generate a Let's Encrypt SSL certificate for Nginx, you can use the certbot tool. Here's how to do it:
Step 15 : Map the domain to the server using DNS.
Step 16 : Install certbot:
sudo apt install certbot python3-certbot-nginx
Step 17 : Run the certbot command to obtain and install the SSL certificate:
sudo certbot --nginx
Step 18 : Follow the on-screen instructions to configure certbot and obtain the SSL certificate. certbot will automatically configure Nginx to use the newly obtained certificate.
Step 19 : Verify that the SSL certificate is properly installed by visiting your website using https:// in a web browser and checking for the padlock icon in the address bar.
