Here’s a step-by-step guide to install PHP and MySQL on a Linux VPS:

---

1. Update Your System
Ensure your system packages are up-to-date:

Code:

sudo apt update && sudo apt upgrade -y

---

2. Install MySQL

1. Install MySQL server:
   
   Code:

   sudo apt install mysql-server -y
2. Secure MySQL installation:
   
   Code:

   sudo mysql_secure_installation
   • You'll be prompted to set a root password, remove test databases, disallow remote root login, etc. Follow the prompts to harden the installation.
     
3. Verify MySQL is running:
   
   Code:

   sudo systemctl status mysql

---

3. Install PHP

1. Install PHP and common extensions:
   
   Code:

   sudo apt install php libapache2-mod-php php-mysql -y
   Replace
   
   Code:

   libapache2-mod-php
   with
   
   Code:

   php-fpm
   if you're using Nginx instead of Apache.
   
2. Verify PHP installation:
   
   Code:

   php -v

---

4. Install a Web Server (if not already installed)
For Apache:

Code:

sudo apt install apache2 -y

For Nginx:

Code:

sudo apt install nginx -y

---

5. Configure PHP

1. Adjust PHP settings if needed: Edit the PHP configuration file:
   
   Code:

   sudo nano /etc/php/{PHP_VERSION}/apache2/php.ini
   Replace
   
   Code:

   {PHP_VERSION}
   with your installed PHP version (e.g.,
   
   Code:

   8.2
   ).
   • Common settings to modify:
     • Code:

       upload_max_filesize
     • Code:

       post_max_size
     • Code:

       memory_limit
2. Restart the web server to apply changes:
   
   Code:

   sudo systemctl restart apache2  # For Apache
sudo systemctl restart nginx    # For Nginx

---

6. Test PHP

1. Create a PHP info file:
   
   Code:

   echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php
2. Access it in your browser at
   
   Code:

   http://YOUR_SERVER_IP/info.php
   .
   

---

7. Enable MySQL in PHP
Ensure PHP's MySQL extension is enabled (usually done automatically). Test it using your PHP scripts or by connecting to MySQL with PHP.

---

8. Optional: Install PHPMyAdmin
If you'd like a web interface to manage MySQL:

Code:

sudo apt install phpmyadmin -y

Follow the prompts to configure it.

---

9. Security Best Practices

• Disable the PHP info file after testing:
  
  Code:

  sudo rm /var/www/html/info.php
• Secure MySQL and PHP configurations according to your use case.
