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 updateCopy Code - Then, install the Nginx web server with:
sudo apt install nginx -yCopy Code - Now, check the installed Nginx version:
sudo nginx -versionCopy Code - The output should look similar to this:
nginx version: nginx/1.24.0 (Ubuntu)Copy Code
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 nginxCopy Code - Then, manually start the Nginx service:
sudo systemctl start nginxCopy Code - To stop the Nginx service:
sudo systemctl stop nginxCopy Code - Then, apply configuration changes by restarting Nginx:
sudo systemctl restart nginxCopy Code - Next, confirm Nginx is running:
sudo systemctl status nginxCopy Code
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.confCopy Code - 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; } }Copy Code - Then, save and close the file.
- Now, it is time to validate the Nginx configuration:
sudo nginx -tCopy Code
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 successfulCopy Code - 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/Copy Code - Next, create the directory to store the web application files:
sudo mkdir -p /var/www/app.example.comCopy Code - Now, create an `index.html` file for testing:
sudo nano /var/www/app.example.com/index.htmlCopy Code
Add this sample HTML:<html> <head></head> <body> <h1>Greetings from Vultr</h1> </body> </html>Copy Code - Then, save and close the file.
- Now, apply the new virtual host configuration:
sudo systemctl restart nginxCopy Code - Confirm Nginx serves the virtual host:
curl http://app.example.comCopy Code
The output should display:Greetings from VultrCopy Code
Step 4: Configure Firewall Rules
- Enable HTTP (port 80):
sudo ufw allow 80/tcpCopy Code - Enable HTTPS (port 443):
sudo ufw allow 443/tcpCopy Code - Check active firewall rules:
sudo ufw statusCopy Code
