Introduction

 

How do I install WHMCS?

 

Procedure

 

There are three methods of installing WHMCS.

 

Method 1: Install WHMCS as Site Software (cPanel and WHM version 86 and later)

1. Navigate to cPanel’s Site Software interface (cPanel >> Home >> Software >> Site Software).

2. Under Automation, click WHMCS.

3. Under the Install tab, select a domain from the Installation Domain menu. The system will check whether the domain has a WHMCS license.

    • If the domain owns a license, click Install.

    • If you possess a license for the domain, but the system does not detect it, click Enter a license manually. Enter your WHMCS license in the License Key text box and click Install.

    • If the domain does not possess a license, click Buy License. The system will connect to the cPanel Store so you can buy a license. After your purchase, the cPanel Store will return you to the Site Software interface. Then, click Install.

4. After the installation completes, the interface will provide a success message, the username, password, and the WHMCS administration URL.

 

Method 2: Install WHMCS as Site Software (cPanel and WHM version 84 and earlier)

 

1. Navigate to cPanel’s Site Software interface (cPanel >> Home >> Software >> Site Software).

2. Under Automation, click WHMCS.

3. Under the Install tab, select a domain from the Installation Domain menu and click Install.

 

For advanced configuration installations, log in to your cPanel account and perform the following steps:

 

1. Navigate to cPanel’s Site Software interface (cPanel >> Home >> Software >> Site Software).

2. Under Automation, click WHMCS.

3. Under the Install tab, click Show Advanced Configuration.

4. Select a domain from the Installation URL menu. You can enter directory if you desire.

5. Enter an administrator username in the Admin User text box.

6. Enter and confirm the new password in the appropriate text boxes.

7. Enter your email address in the Email text box.

8. Click Install.

 

Method 3: Install WHMCS Manually

 

To install WHMCS manually, perform the following steps:

 

1. Navigate to the Download WHMCS website.

2. Enter you license key in the text box and click Validate and Download. The system will download a .zip file that contains the WHMCS files.

3. Unzip the contents of the .zip file to a folder on your computer.

4. In the WHMCS folder, rename the configuration.php.new file to configuration.php.

5. Upload the WHMCS folder to your website. You may rename the folder, if desired

6. Navigate to example.com/whmcs/install/install.php, where example.com represents your domain. If you uploaded the WHMCS files to a directory other than public_html, paste that path after your domain name in the URL.

7. Follow the instructions to complete the installation.

8. Change the permissions on the directories. To do this, run the following commands:

chmod 400 configuration.php
chmod 777 attachments
chmod 777 downloads
chmod 777 templates_c

 

9. Navigate to the directory where you uploaded WHMCS and delete the install directory

10. Log in to your WHMCS account with your license key.
