Before you dive into deploying SafeLine WAF, there are a few essential prerequisites to ensure your setup goes smoothly. This guide walks you through preparing a homelab environment using Ubuntu Server and Kali Linux, along with the Damn Vulnerable Web Application (DVWA) for testing.
Step 2: Prerequisites
2.1 Clone DVWA from Git
cd /var/www/html
sudo git clone https://github.com/digininja/DVWA.git
If git is not installed:
sudo apt-get install -y git
2.2 Set File Permissions
sudo chown -R www-data:www-data DVWA
sudo chmod -R 755 DVWA
2.3 DNS Resolution Setup
Edit /etc/hosts on both Kali and Ubuntu:
sudo nano /etc/hosts
Add the following line:
10.0.0.147 dvwa.local
This allows access to DVWA at:
http://dvwa.local:8080/DVWA/
2.4 Ubuntu Configurations
Install OpenSSL
sudo apt-get install -y openssl
Install and Configure LAMP Stack
sudo apt-get install -y apache2 php php-mysql mysql-server
sudo mysql_secure_installation
# Set MySQL root password: ubuntu (testing purposes)
Update DVWA Config File
Edit DVWA/config/config.inc.php:
$DBMS = 'MySQL';
$db = 'dvwa';
$user = 'dvwa_user';
$pass = 'p@ssw0rd';
$host = 'localhost';
Create DVWA Database and User
sudo mysql -u root -p
Inside MySQL shell:
CREATE DATABASE dvwa;
CREATE USER 'dvwa_user'@'localhost' IDENTIFIED BY 'p@ssw0rd';
GRANT ALL ON dvwa.* TO 'dvwa_user'@'localhost';
FLUSH PRIVILEGES;
exit;
Initialize DVWA
Visit:
http://dvwa.local/setup.php
Click Create/Reset Database.
2.5 Change DVWA Listening Port to 8080
sudo nano /etc/apache2/ports.conf
Change:
Listen 80
to:
Listen 8080
2.6 Change Apache Virtual Host Port
sudo nano /etc/apache2/sites-available/000-default.conf
Update:
<VirtualHost *:8080>
...
</VirtualHost>
Restart Apache:
sudo systemctl restart apache2
✅ Next Step: With your environment ready, we can move on to installing and configuring SafeLine WAF to protect DVWA.
