Ubuntu Server LAMP Install Command: The Ultimate Guide

Introduction

Greetings, fellow tech enthusiasts! Are you looking for a powerful, versatile, and free server operating system? Look no further than Ubuntu Server, which boasts a vast and active community, frequent updates, and a robust command-line interface. However, setting up an Apache web server, MySQL database, and PHP scripting language can be daunting for newcomers. Fear not, as this article will guide you through the Ubuntu Server LAMP install command step by step.

First, let’s define what LAMP means. It stands for:

Letter
Component
L
Linux – the operating system kernel
A
Apache – the web server software
M
MySQL – the database management system
P
PHP – the scripting language

Together, these components form a powerful web application stack that can handle dynamic content, store and retrieve data, and integrate with many other technologies.

What are the benefits of using Ubuntu Server LAMP?

Ubuntu Server LAMP offers many advantages over other server software:

🚀 Speed and performance: Apache is known for its stability and scalability, allowing it to handle millions of requests per day without breaking a sweat. MySQL also supports advanced indexing and caching, making it ideal for high-traffic sites.

🛡️ Security: Ubuntu Server comes with a built-in firewall, SELinux, and AppArmor, which can prevent unauthorized access, mitigate attacks, and isolate processes.

💰 Cost-effectiveness: Ubuntu Server is completely free, open-source, and can run on low-end hardware. LAMP itself is also free and can reduce licensing costs compared to proprietary software.

🌎 Compatibility: LAMP is cross-platform and can run on Windows or macOS with some tweaks. It also supports many programming languages, frameworks, and CMSs, such as WordPress, Drupal, and Joomla.

💪 Customizability: Ubuntu Server and LAMP are highly configurable and modular, allowing you to add or remove components, optimize settings, and automate tasks.

Now that you know the benefits, let’s dive into the Ubuntu Server LAMP install command!

Ubuntu Server LAMP Install Command: Step by Step

Step 1: Update the system

Before installing any software, it’s essential to update your Ubuntu Server distribution to the latest version, as it may contain security patches, bug fixes, and new features. To do so, open a terminal and type:

sudo apt update

sudo apt upgrade

This will download and install any available updates and prompt you to confirm. Hit Y and Enter to proceed.

Step 2: Install Apache

The first component of LAMP is the Apache web server, which is widely used by websites worldwide. To install it, type:

sudo apt install apache2

This will download and install Apache and its dependencies. You can verify that Apache is running by typing:

sudo systemctl status apache2

You should see a green “active (running)” message, indicating that Apache is up and running. You can also check its default website by typing your server’s IP address or hostname in a web browser.

Step 3: Install MySQL

The second component of LAMP is MySQL, which is a popular and powerful database management system. To install it, type:

sudo apt install mysql-server

This will download and install MySQL and prompt you to set a root password. Choose a strong and unique password and remember it, as it will be required to access MySQL later.

You can verify that MySQL is running by typing:

sudo systemctl status mysql

You should see a green “active (running)” message, indicating that MySQL is up and running.

Step 4: Install PHP

The third component of LAMP is PHP, which is a popular and versatile scripting language used for web development. To install it, type:

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

This will download and install PHP and its extensions, as well as a module to integrate it with Apache. You can verify that PHP is working by creating a test file in Apache’s document root folder:

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

Inside this file, type:

<?php phpinfo(); ?>

This will display a PHP information page when accessed from a web browser. To test it, type your server’s IP address or hostname followed by “/info.php” in a web browser. You should see a lot of technical details about your PHP installation.

Step 5: Configure Firewall

Now that you have installed the LAMP stack, it’s important to secure it by configuring the firewall to allow only necessary traffic. To do so, type:

sudo ufw app list

This will show you a list of available firewall profiles, including Apache Full, which allows both HTTP and HTTPS traffic. To enable it, type:

sudo ufw allow in "Apache Full"

This will allow incoming traffic to Apache and ensure that the firewall is active. You can verify the firewall’s status by typing:

sudo ufw status

You should see a green “Status: active” message, indicating that the firewall is up and running.

Step 6: Test LAMP

Finally, it’s time to test your LAMP installation and see if everything works as expected. To do so, create a test PHP file in Apache’s document root folder:

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

Inside this file, type:

<?php// Create a new database connection$conn = new mysqli("localhost", "root", "YOUR_PASSWORD", "testdb");// Check if the connection is successfulif ($conn->connect_error) {die("Connection failed: " . $conn->connect_error);}echo "Connected successfully"; ?>

This will connect to the MySQL database using PHP’s mysqli extension and output a message if successful. To test it, type your server’s IP address or hostname followed by “/test.php” in a web browser. You should see a message saying “Connected successfully” if everything went well.

Advantages and Disadvantages of Ubuntu Server LAMP

Advantages
