Complete Guide to Installing a LAMP Stack on Ubuntu

**How to Install a LAMP Stack on Ubuntu**

A LAMP stack refers to a set of open-source software that includes Linux, Apache, MySQL, and PHP. This guide will walk you through the steps to install a LAMP stack on an Ubuntu system.

Step 1: Update System Packages
“`bash
sudo apt update
sudo apt upgrade
“`
This will ensure that your system packages are up to date before installing the LAMP stack.

Step 2: Install Apache
“`bash
sudo apt install apache2
“`
Apache is a popular web server software. After installing Apache, you can start and enable it with the following commands:
“`bash
sudo systemctl start apache2
sudo systemctl enable apache2
“`

Step 3: Install MySQL
“`bash
sudo apt install mysql-server
“`
During the installation process, you will be prompted to set a root password for MySQL. Once installed, you can secure MySQL by running:
“`bash
sudo mysql_secure_installation
“`

Step 4: Install PHP
“`bash
sudo apt install php libapache2-mod-php php-mysql
“`
This command will install PHP along with the necessary modules to integrate it with Apache and MySQL.

Step 5: Test PHP
Create a PHP info file to test if PHP is working properly:
“`bash
echo “” | sudo tee /var/www/html/info.php
“`
You can access this file in a web browser by visiting `http://your_server_ip/info.php`. If PHP is working correctly, you should see a page displaying PHP configuration information.

Step 6: Configure Apache to Use PHP
Edit the Apache configuration file to enable PHP processing:
“`bash
sudo nano /etc/apache2/mods-enabled/dir.conf
“`
Move the PHP index file to the first position within the `` block, as shown below:
“`

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

“`
Save the file and restart Apache for the changes to take effect:
“`bash
sudo systemctl restart apache2
“`

Congratulations! You have successfully installed a LAMP stack on your Ubuntu system. You can now deploy web applications that require Apache, MySQL, and PHP.
