Install LAMP Stack on Ubuntu VPS: Full Tutorial

If you’re looking to host dynamic websites or web applications, mastering how to install LAMP Stack on Ubuntu VPS is essential. This tutorial breaks down the process, guiding you quickly through each step in a clear, easy-to-understand way. Whether you’re a developer, system admin, or hobbyist, by the end of this, you’ll have a robust LAMP server ready to power your projects.

What is the LAMP Stack and Why Install It on Ubuntu VPS?

The LAMP Stack combines four powerful components:

• Linux – the operating system (Ubuntu VPS is a popular choice)
• Apache – the web server that handles HTTP requests
• MySQL – the database that stores information
• PHP – the scripting language that generates dynamic content

This stack forms the backbone of many websites worldwide. Using Ubuntu VPS, a flexible and scalable cloud environment, ensures you have complete control and performance for hosting your applications.

Preparing Your Ubuntu VPS for LAMP Stack Installation

Before diving into installation, we need to prep your Ubuntu VPS environment to ensure a smooth setup.

Accessing Your Ubuntu VPS

Connect to your server using SSH with the following command:

ssh username@your_ubuntu_vps_ip

Replace username and your_ubuntu_vps_ip with your VPS credentials.

Update and Upgrade the System Packages

Start by running the latest updates to make sure all software is current:

sudo apt update && sudo apt upgrade -y

This step minimizes compatibility issues during installation.

Setting Up a Firewall for Security

Securing your VPS is crucial. Use ufw to control incoming traffic:

sudo ufw allow OpenSSH
sudo ufw allow 'Apache Full'
sudo ufw enable

This configures the firewall to allow SSH and web traffic while restricting other connections.

Step 1: Installing Apache Web Server on Ubuntu VPS

Apache is the most widely used web server. Here’s how to install it:

sudo apt install apache2 -y

Once installed, start and enable Apache:

sudo systemctl start apache2
sudo systemctl enable apache2

Verify your web server is running by visiting your VPS IP address in a browser. You should see the default Apache welcome page.

Testing Apache Installation

Check Apache service status with:

sudo systemctl status apache2

If the service is active and running, your Apache installation is good to go.

Step 2: Installing MySQL Database Server

MySQL is the database system used to store your website’s data.

sudo apt install mysql-server -y

Start and enable MySQL:

sudo systemctl start mysql
sudo systemctl enable mysql

Secure MySQL Server

Run the security script to set a root password, remove test users, and tighten security:

sudo mysql_secure_installation

Follow the prompts carefully. This is an important step to prevent unauthorized database access.

Verify MySQL Installation

sudo systemctl status mysql

You can also log in to the MySQL shell to confirm:

sudo mysql -u root -p

Type your password to enter.

Step 3: Installing PHP and Integrating with Apache

PHP powers dynamic content and server-side scripting.

sudo apt install php libapache2-mod-php php-mysql -y

This command installs PHP along with the Apache PHP module and MySQL extension for database interaction.

Check PHP Version

php -v

Confirm the installation is successful.

Testing PHP Processing on Apache

Create a PHP info page to ensure Apache and PHP are working together:

sudo nano /var/www/html/info.php

Add the following to the file:

Save and exit. Now, access http://your_ubuntu_vps_ip/info.php in your browser. You should see PHP configuration details.

Step 4: Adjusting Apache Directory Index for PHP

By default, Apache serves index.html before index.php, which may prevent PHP pages from loading as the default.

To fix this, modify the dir.conf file:

sudo nano /etc/apache2/mods-enabled/dir.conf

Edit the order so that index.php is before index.html like this:

DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm

Save the file and reload Apache:

sudo systemctl reload apache2

Step 5: Testing the Full LAMP Stack

With Apache, MySQL, and PHP installed, test the complete stack with a simple database connection script.

Create a file:

sudo nano /var/www/html/testdb.php

Add this sample PHP code:

Remember to replace your_mysql_root_password with your actual password.

Visit http://your_ubuntu_vps_ip/testdb.php. A message saying “Connected successfully to MySQL database” confirms your LAMP stack is working perfectly.

Optimizing and Securing Your LAMP Stack on Ubuntu VPS

Installing the stack is just the beginning. Let’s ensure it runs efficiently and safely.

Enable UFW Firewall Rules for Web Traffic

If not already done, ensure your firewall allows web traffic:

sudo ufw allow 'Apache Full'
sudo ufw status

Keep Your System Updated

Regularly update packages to patch vulnerabilities:

sudo apt update && sudo apt upgrade -y

Configure MySQL User Accounts Properly

Avoid using the default root user for application databases. Instead, create a new MySQL user for your web apps:

sudo mysql -u root -p

CREATE DATABASE myappdb;
CREATE USER 'appuser'@'localhost' IDENTIFIED BY 'strong_password';
GRANT ALL PRIVILEGES ON myappdb.* TO 'appuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Enable SSL with Let’s Encrypt

Protect your web traffic by enabling HTTPS with a free SSL certificate:

sudo apt install certbot python3-certbot-apache -y
sudo certbot --apache

Follow the prompts to install and configure SSL certificates automatically.
