How to Install WHMCS?
Step 1: Purchase a WHMCS License
Get a license from the official WHMCS website or your hosting provider. You’ll receive license details and a download link.
Step 2: Download WHMCS
Log in to your WHMCS account. Download the latest WHMCS installation package (a .zip file).
Step 3: Upload WHMCS Files to Your Server
Extract the downloaded .zip file. Use FTP or your hosting control panel’s File Manager to upload the WHMCS files to your desired directory (e.g., yourdomain.com/whmcs).
Step 4: Create a Database
Log in to your hosting control panel (like cPanel). Create a new MySQL database and user. Note down the database name, username, and password.
Step 5: Run the WHMCS Installer
Visit your domain with the WHMCS folder in the browser (e.g., yourdomain.com/whmcs/install). Follow the installation wizard. Enter your license key, database details, and admin account credentials.
Step 6: Configure WHMCS
Once installed, log in to the WHMCS admin panel. Set up general settings (company name, logo, currencies, etc.). Add payment gateways, hosting products, and domain registrar modules.
Step 7: Secure Your Installation
Delete the /install folder from your WHMCS directory. Set proper file permissions (e.g., configuration.php to 400 or 444). Enable SSL (HTTPS) to secure client data.
Step 8: Start Using WHMCS
Test by creating a sample order and invoice. Confirm payment gateway, domain registrar, and hosting provisioning integrations are working correctly.
Best Practices After Installing WHMCS
1. Keep WHMCS Updated: Always upgrade to the latest WHMCS version to ensure you get security patches, bug fixes, and new features that keep your platform stable and safe.
2. Secure Your Admin Area: Change the default admin directory name, enable two-factor authentication, and restrict admin access by IP address whenever possible.
3. Use SSL for All Pages: Force HTTPS across your WHMCS installation to protect sensitive client information such as login credentials, invoices, and payment details.
4. Set Correct File Permissions: Make sure configuration.php is read-only and writable folders like attachments and templates_c have proper restricted permissions.
5. Automate Backups: Schedule regular database and file backups. Store backups securely off-site to quickly recover in case of data loss or server failure.
6. Configure Cron Jobs Correctly: Ensure automation cron jobs run as scheduled to handle billing, renewals, and reminders without interruptions.
7. Monitor Email Deliverability: Use SMTP with proper authentication for sending emails. Monitor bounce rates to avoid issues with invoices or support notifications not reaching clients.
8. Test Your Setup Regularly: Run test orders, payments, and renewals to confirm that integrations with payment gateways, domain registrars, and hosting platforms are working smoothly.
