If your license key was obtained via a reseller and you don't have a login for our members area, your reseller can provide the latest WHMCS files to you.
- Visit http://download.whmcs.com/
- Click the Download button under the Full Release heading; this will be the latest release version.
You can also use the WHMCS Internal API to retrieve this information.
WHMCS is encrypted using Ioncube to protect the source code. These days most servers/webhosts have Ioncube support compiled into the PHP build by default so you don't normally need to do anything extra for it. However if you find you do need to install Ioncube on your server, then you can find out how to do this in our Ioncube Installation Tutorial
Creating a Database
WHMCS uses a MySQL database to store all settings and data. You will be asked to create one during the installation process, so best to create one beforehand. Technical information is detailed on the Database Setup page.
Restrict Database Privileges
For day to day use, only the following database privileges are required. All others may be disabled.
- LOCK TABLES
Please note that installation, upgrading, activating, and deactivating modules require the following additional privileges.
Installing WHMCS is very simple. The following steps will guide you through the process:
- Unzip the contents of the zip file to a folder on your computer
- Rename the file configuration.php.new to configuration.php
- Upload the entire whmcs folder to your website - if you experience problems, try uploading in binary mode
- Next you can rename the folder if desired (billing, clients, etc...)
- Now visit the installation script at http://www.yourdomain.com/whmcs/install/install.php to run the installer process - if you get an Ioncube related error message, see the installation Ioncube steps above
- Follow the instructions on screen to install which will involve setting file permissions as listed below, entering your license key and setting up your primary admin account
When complete, delete the install folder from your web server and ensure the configuration.php file permissions are restricted.
Required file & folders permissions
/configuration.php CHMOD 400 Readable
/attachments CHMOD 777 Writeable
/downloads CHMOD 777 Writeable
/templates_c CHMOD 777 Writeable
The above applies unless your php is suPHP or PHPSuExec, it which case you directories should be more restrictive. If using DSO as your php handler, you must use 644 permissions. It is important that permissions are limited to only the account that owns the web server process and that no other system accounts can read your configuration file or modify any files related to WHMCS.
