? Article 5: How to Install LAMP Stack on Ubuntu 22.04 LTS

LAMP = Linux + Apache + MySQL + PHP
Used for hosting websites, applications, and testing environments.

???? Part A: Preparation

1. Laptop/Desktop with Ubuntu 22.04 LTS installed.
   
   

2. Open a Terminal (shortcut: Ctrl + Alt + T).
   
   

3. Run all commands with sudo (superuser).
   
   

???? Hint: If system asks for password → type your login password → press Enter.

???? Part B: Update System

Always update first:

sudo apt update && sudo apt upgrade -y

???? Part C: Install Apache (Web Server)

1. Install Apache:
   
   

sudo apt install apache2 -y

2. Check service is running:
   
   

sudo systemctl status apache2

(Press q to exit status view.)

3. Test in browser → open:
   
   

http://localhost

✅ You should see “Apache2 Ubuntu Default Page”.

???? Hint: If page not loading → check firewall:

sudo ufw allow in "Apache Full"

???? Part D: Install MySQL (Database)

1. Install MySQL:
   
   

sudo apt install mysql-server -y

2. Secure MySQL:
   
   

sudo mysql_secure_installation

Follow prompts:

• Validate password plugin? → N (optional, can say Y if you want strong policy)
  
  

• Set root password? → Y → enter password
  
  

• Remove anonymous users? → Y
  
  

• Disallow root remote login? → Y
  
  

• Remove test DB? → Y
  
  

• Reload privileges? → Y
  
  

3. Test MySQL login:
   
   

sudo mysql -u root -p

(Enter password you just set → should see mysql> prompt.)
Type exit; to leave.

???? Part E: Install PHP

1. Install PHP + common modules:
   
   

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

2. Verify PHP version:
   
   

php -v

✅ Should show PHP 8.1 or later (default in Ubuntu 22.04).

???? Part F: Test PHP with Apache

1. Create a test PHP file:
   
   

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

2. Add:
   
   

<?php

phpinfo();

?>

3. Save (Ctrl+O → Enter → Ctrl+X).
   
   

4. Open in browser:
   
   

http://localhost/info.php

✅ Should show a purple PHP information page.

???? Remove this file later for security:

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

???? Part G: Manage Services

Check status / start / stop:

sudo systemctl status apache2

sudo systemctl status mysql

Restart if needed:

sudo systemctl restart apache2

sudo systemctl restart mysql

???? Part H: Permissions (For Web Development)

1. Default website folder: /var/www/html
   
   

2. Give ownership to your user (replace username):
   
   

sudo chown -R username:username /var/www/html

3. Now you can copy/paste website files directly.
   
   

???? Part I: Optional Add-Ons

• phpMyAdmin (GUI for MySQL):
  
  

sudo apt install phpmyadmin -y

When asked:

• Select apache2
  
  

• Configure db for phpMyAdmin → Y
  
  

• Set phpMyAdmin password
  
  

Access at:

http://localhost/phpmyadmin

• Additional PHP modules (if apps need them):
  
  

sudo apt install php-cli php-curl php-xml php-gd php-mbstring unzip -y

General Hints ????

• Use systemctl to manage services (Apache/MySQL).
  
  

• If PHP page downloads instead of running → check Apache has php module enabled:
  
  

sudo a2enmod php8.1

sudo systemctl restart apache2

• For remote servers → open firewall:
  
  

sudo ufw allow 'Apache Full'

• To change MySQL root password later:
  
  

sudo mysql

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'NewPass123!';

FLUSH PRIVILEGES;

EXIT;

✅ LAMP stack is now ready!
You can deploy websites in /var/www/html/ or configure virtual hosts for multiple sites.
