System Requirements

For successful operation of and updates to of self-hosted WHMCS installations, your system must meet the minimum system requirements for your WHMCS version.

Secure Writeable Directories

We recommend moving all writeable directories to a secure, private location and updating related items to prevent unauthorized web-based access to self-hosted WHMCS installations.

Set Up a Test Environment

To prevent problems, we recommend testing updates and customizations in a test environment before applying them to your self-hosted WHMCS installation.

Knowledgebase

WHMCS includes all of the tools you need to create a custom knowledgebase for your company. Customers can view this in the Client Area.

Downloads

Downloads can include product user manuals or relevant software utilities. They can be products you sell, like custom themes for websites, or materials related to support or customer service needs.



Prune Ticket Attachments

Prune ticket attachments to automatically delete and purge ticket attachments from closed tickets after a set period of inactivity.

Storage Settings

You can configure storage settings that determine how WHMCS stores many types of files. This can include different types of attachments, downloads, knowledgebase images, and more. You can add local locations or configure storage using services like Amazon S3™.

System Cleanup

WHMCS allows you to prune logs to reduce the size of the database and reduce disk space.

Migrate Local Storage

You can migrate your data between local storage locations, or migrate data from an existing location like an Amazon S3™ bucket.


Set Up Amazon S3 Storage

WHMCS supports using Amazon S3™ and Amazon S3-compatible services as storage providers. After you create an Amazon S3 bucket, you can configure it as your storage location.
