How to Install Nginx Web Server on Ubuntu 24.04
Nginx is a powerful and efficient web server widely used to serve web applications, act as a reverse proxy, and handle load balancing.
Today, we will install Nginx on Ubuntu 24.04, configure virtual hosts, and set up firewall rules.
Step 1: Install Nginx
- First, run the following command to make sure the server’s package index is up to date:
sudo apt update - Then, install the Nginx web server with:
sudo apt install nginx -y - Now, check the installed Nginx version:
sudo nginx -version - The output should look similar to this:
nginx version: nginx/1.24.0 (Ubuntu)
Step 2: Manage Nginx System Service
Nginx uses `systemd` for service management. Here’s how to control Nginx processes:
- Ensure Nginx starts automatically when the server reboots:
sudo systemctl enable nginx - Then, manually start the Nginx service:
sudo systemctl start nginx - To stop the Nginx service:
sudo systemctl stop nginx - Then, apply configuration changes by restarting Nginx:
sudo systemctl restart nginx - Next, confirm Nginx is running:
sudo systemctl status nginx
Step 3: Configure Nginx Virtual Hosts
Virtual hosts allow Nginx to serve multiple domains or applications from a single server. Let’s create a new virtual host.
- First, create a new configuration file, for example, `app.example.com.conf`:
sudo nano /etc/nginx/sites-available/app.example.com.conf - Then, add the following content:
server {
listen 80;
listen [::]:80;
server_name app.example.com;
root /var/www/app.example.com;
index index.html;
location / {
try_files $uri $uri/ =404;
}
}
- Then, save and close the file.
- Now, it is time to validate the Nginx configuration:
sudo nginx -t
Successful output will look like this:
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
- Then, link the configuration file to the `sites-enabled` directory:
sudo ln -s /etc/nginx/sites-available/app.example.com.conf /etc/nginx/sites-enabled/ - Next, create the directory to store the web application files:
sudo mkdir -p /var/www/app.example.com - Now, create an `index.html` file for testing:
sudo nano /var/www/app.example.com/index.html
Add this sample HTML:
<html>
<head></head>
<body>
<h1>Greetings from Vultr</h1>
</body>
</html>
- Then, save and close the file.
- Now, apply the new virtual host configuration:
sudo systemctl restart nginx - Confirm Nginx serves the virtual host:
curl http://app.example.com
The output should display:Greetings from Vultr
Step 4: Configure Firewall Rules
- Enable HTTP (port 80):
sudo ufw allow 80/tcp - Enable HTTPS (port 443):
sudo ufw allow 443/tcp - Check active firewall rules:
sudo ufw status
