A LAMP server is one of the most widely used server environments for hosting dynamic websites and web applications. The acronym LAMP represents Linux, Apache, MySQL, and PHP, four open source technologies that have stood the test of time and still power a large percentage of the modern web.Â
If you are using a Linux VPS, installing a LAMP stack gives you a flexible, cost effective, and production ready platform. LAMP is an ideal choice for developers, startups, and businesses that want stability without unnecessary complexity.Â
In this guide, you will learn How to install lamp stack, step by step, using Ubuntu as the reference distribution. The process is beginner friendly, yet solid enough for real world deployment.
What Is a LAMP Server and How Does It Work?
A LAMP server is a stack, meaning several components working together. When a visitor opens a website hosted on a LAMP server, Apache receives the request. If the page requires dynamic data, PHP executes the logic and communicates with MySQL. The final result is then sent back to the user’s browser. Structure is like this:
- Linux: Which acts as the operating system
- Apache: Which handles incoming web requests
- MySQL: Which stores application data
- PHP: Which processes dynamic content
This architecture is simple, powerful, and extremely well documented, which is why it remains a standard choice for VPS hosting.
Prerequisites and How To Install Lamp Successfully
While this tutorial focuses on Ubuntu, the same logic applies to other Linux distributions such as Debian, AlmaLinux, and Rocky Linux. Commands may differ slightly, but the core concept of installing a lamp server remains identical.
Ubuntu is recommended because of its stability, long term support releases, and extensive documentation.Â
LAMP stacks are commonly used for:
- WordPress hosting
- Custom PHP applications
- REST APIs
- Internal dashboards
- Development and staging environments
Despite newer stacks emerging, LAMP remains relevant due to its simplicity and reliability.
Prerequisites
Before proceeding, make sure you have, A running Linux VPS, Ubuntu 20.04 or 22.04 installed, Root or sudo user access and SSH access to the server.Â
- CPU: Modern 64-bit processor recommended for optimal performance.Â
- RAM: Minimum 1GB, but 2GB or more is ideal for smoother performance and handling multiple users.Â
- Storage: Minimum 10GB for the operating system and LAMP software, plus space for website files, databases, and logs.
If your VPS is freshly deployed, the setup process will be even smoother. And you can easily follow these commands to install LAMP.
Step 1: Update the System
First of all, you need to keep your system updated to reduce compatibility and security issues. Go to terminal and run this:
sudo apt update && sudo apt upgrade -y
This ensures your Ubuntu install LAMP process starts from a clean and secure base.
Step 2: Install Apache Web Server
Apache is responsible for serving web pages to users. So you must install it correctly.
Install Apache with this code:
sudo apt install apache2 -y
After installation, enable Apache through the firewall:
sudo ufw allow 'Apache'
Check Apache status:
sudo systemctl status apache2
If the service is active, open your VPS IP address in a browser. Seeing the Apache default page confirms the web server is working correctly.
Step 3: Install MySQL Database Server
MySQL is the database engine used by most PHP based applications such as WordPress, Joomla, and custom CMS platforms.
Install MySQL:
sudo apt install mysql-server -y
Secure the installation:
sudo mysql_secure_installation
This process helps you in different ways:
- Set a strong root password
- Remove anonymous users
- Disable remote root access
- Delete test databases
These steps are essential for any production lamp server.
Step 4: Install PHP and Required Modules
PHP acts as the bridge between Apache and MySQL.
Install PHP and common extensions:
sudo apt install php libapache2-mod-php php-mysql -y
Verify PHP installation:
php -v
To ensure Apache prioritizes PHP files, you may adjust the directory index configuration, especially if you plan to host applications that rely heavily on PHP.
Step 5: Test the LAMP Stack
After that you need to create a test file, create a PHP test file with this code:
sudo nano /var/www/html/info.php
Add:
<?php phpinfo(); ?>
Visit:
http://your_server_ip/info.php
If the PHP information page loads, your how to install lamp stack process is complete.
Delete the test file afterward to prevent information disclosure:
sudo rm /var/www/html/info.php
Step 6 (Optional): Configure Virtual Hosts
If you plan to host multiple websites, Apache virtual hosts are essential. They allow different domains to run on the same Linux VPS, each with its own configuration and document root. This setup is common in VPS environments and works seamlessly with a LAMP server.
Performance Optimization Tips
Out of the box, LAMP works well. However, small tweaks can improve performance:
1. Enable Apache modules like rewrite
The Apache rewrite module allows you to modify URLs before they are processed by the server. It is most commonly used for clean, user friendly URLs, redirects, and SEO friendly routing. From a performance and usability perspective, clean URLs improve caching behavior, search engine indexing, and overall user experience. Enabling rewrite is considered a standard step when configuring a production ready LAMP server.
2. Adjust PHP memory limits
PHP memory limits define how much RAM a single PHP script is allowed to consume. On default installations, this limit is often set conservatively, which can cause issues for larger applications or plugins. If a PHP script exceeds its memory limit, execution stops and results in fatal errors. This is common when running content heavy websites, complex forms, or database intensive operations.
3. Use MySQL query caching
MySQL query caching stores the result of frequent database queries in memory. When the same query is executed again, MySQL can return the cached result instead of reprocessing the query. This significantly reduces database load and improves response times, especially for read heavy websites where the same data is requested repeatedly. Blogs, news websites, and dashboards benefit the most from query caching.
4. Enable OPcache for PHP
OPcache is a PHP extension that improves performance by storing precompiled PHP bytecode in memory. Normally, PHP scripts are compiled on every request, which adds unnecessary overhead. With OPcache enabled, PHP skips recompilation and directly executes cached bytecode. This results in faster page loads, reduced CPU usage, and better scalability under traffic spikes.
Why Install LAMP Server on a Linux VPS?
Using Ubuntu install LAMP on a VPS instead of shared hosting provides clear technical advantages:
- Dedicated CPU and RAM resources
- Root access for full configuration control
- Improved security isolation
- Better performance under traffic spikes
- Freedom to host multiple websites
Many developers start with a Buy Cheap VPS plan to reduce costs while maintaining full flexibility. As traffic and complexity increase, upgrading the VPS is straightforward and does not require reinstalling the LAMP stack.
When Should You Scale Your Linux VPS for LAMP?
As your project grows and attracts more users, the demands placed on your server naturally increase. One of the earliest warning signs is slower page load times, especially during peak traffic periods. You may also observe consistently high CPU or RAM usage, which indicates that your current VPS resources are being pushed to their limits. Another common signal is slower database queries, as MySQL begins to struggle with larger datasets and increased concurrent requests.
These symptoms usually mean that your applications are healthy but constrained by hardware limits. At this stage, upgrading your Linux VPS plan becomes the logical next step. The main advantage of VPS hosting is its scalability, allowing you to increase resources without rebuilding your server or migrating to a new environment. This makes scaling smooth, predictable, and far less disruptive than traditional hosting models.
Conclusion
Installing a LAMP server on a Linux VPS is one of the most practical skills for anyone working with web technologies. The combination of Linux, Apache, MySQL, and PHP offers a proven, stable, and flexible environment suitable for both small projects and large scale applications.
By following this guide, you now understand how to install LAMP server, secure it, test it, and prepare it for real world usage. Whether you start with a Cheap VPS or deploy on a higher end server, LAMP gives you a strong foundation that can grow alongside your project.
