CyberPanel Secure Installation Guide

Overview

This document describes the secure installation process for CyberPanel that eliminates hardcoded passwords and implements environment-based configuration.

Security Improvements

✅ Fixed Security Vulnerabilities

1. Hardcoded Database Passwords - Now generated securely during installation
2. Hardcoded Django Secret Key - Now generated using cryptographically secure random generation
3. Environment Variables - All sensitive configuration moved to .env file
4. File Permissions - .env file set to 600 (owner read/write only)

🔐 Security Features

• Cryptographically Secure Passwords: Uses Python's secrets module for password generation
• Environment-based Configuration: Sensitive data stored in .env file, not in code
• Secure File Permissions: Environment files protected with 600 permissions
• Credential Backup: Automatic backup of credentials for recovery
• Fallback Security: Maintains backward compatibility with fallback method

Installation Process

1. Automatic Secure Installation

The installation script now automatically:

1. Generates secure random passwords for:

   • MySQL root user
   • CyberPanel database user
   • Django secret key

2. Creates .env file with secure configuration:

   # Generated during installation
   SECRET_KEY=your_64_character_secure_key
   DB_PASSWORD=your_24_character_secure_password
   ROOT_DB_PASSWORD=your_24_character_secure_password
   

3. Creates .env.backup file for credential recovery

4. Sets secure file permissions (600) on all environment files

2. Manual Installation (if needed)

If you need to manually generate environment configuration:

cd /usr/local/CyberCP
python install/env_generator.py /usr/local/CyberCP

File Structure

/usr/local/CyberCP/
├── .env                    # Main environment configuration (600 permissions)
├── .env.backup            # Credential backup (600 permissions)
├── .env.template          # Template for manual configuration
├── .gitignore             # Prevents .env files from being committed
└── CyberCP/
    └── settings.py        # Updated to use environment variables

Security Best Practices

✅ Do's

• Keep .env and .env.backup files secure
• Record credentials from .env.backup and delete the file after installation
• Use strong, unique passwords for production deployments
• Regularly rotate database passwords
• Monitor access to environment files

❌ Don'ts

• Never commit .env files to version control
• Don't share .env files via insecure channels
• Don't use default passwords in production
• Don't leave .env.backup files on the system after recording credentials

Recovery

Lost Credentials

If you lose your database credentials:

1. Check if .env.backup file exists:

   sudo cat /usr/local/CyberCP/.env.backup
   

2. If backup doesn't exist, you'll need to reset MySQL passwords using MySQL recovery procedures

Regenerate Environment

To regenerate environment configuration:

cd /usr/local/CyberCP
sudo python install/env_generator.py /usr/local/CyberCP

Configuration Options

Environment Variables

Variable	Description	Default
SECRET_KEY	Django secret key	Generated (64 chars)
DB_PASSWORD	CyberPanel DB password	Generated (24 chars)
ROOT_DB_PASSWORD	MySQL root password	Generated (24 chars)
DEBUG	Debug mode	False
ALLOWED_HOSTS	Allowed hosts	localhost,127.0.0.1,hostname

Custom Configuration

To use custom passwords during installation:

python install/env_generator.py /usr/local/CyberCP "your_root_password" "your_db_password"

Troubleshooting

Installation Fails

If the new secure installation fails:

1. Check installation logs for error messages
2. The system will automatically fallback to the original installation method
3. Verify Python dependencies are installed:

   pip install python-dotenv
   

Environment Loading Issues

If Django can't load environment variables:

1. Ensure .env file exists and has correct permissions:

   ls -la /usr/local/CyberCP/.env
   # Should show: -rw------- 1 root root
   

2. Install python-dotenv if missing:

   pip install python-dotenv
   

Migration from Old Installation

Existing Installations

For existing CyberPanel installations with hardcoded passwords:

1. Backup current configuration:

   cp /usr/local/CyberCP/CyberCP/settings.py /usr/local/CyberCP/CyberCP/settings.py.backup
   

2. Generate new environment configuration:

   cd /usr/local/CyberCP
   python install/env_generator.py /usr/local/CyberCP
   

3. Update settings.py (already done in new installations):

   • The settings.py file now supports environment variables
   • It will fallback to hardcoded values if .env is not available

4. Test the configuration:

   cd /usr/local/CyberCP
   python manage.py check
   

Support

For issues with the secure installation:

1. Check the installation logs
2. Verify file permissions
3. Ensure all dependencies are installed
4. Review the fallback installation method if needed

Security Notice: This installation method significantly improves security by eliminating hardcoded credentials. Always ensure proper file permissions and secure handling of environment files.
