How to Purchase a LiteSpeed Web Server License in WHM

1. Introduction to LiteSpeed Web Server

LiteSpeed Web Server is a drop‑in replacement for Apache that reads Apache configuration files directly and supports .htaccess and mod_security rules. You can purchase a LiteSpeed license through the cPanel Store inside WHM.

Important Notes:

• LiteSpeed uses the lsphp binary and does not use the system PHP‑FPM in MultiPHP Manager.
• Hosting providers can disable the LiteSpeed banner in Manage2.
• LiteSpeed is not compatible with the mod_status Apache module. WHM’s Apache Status interface will no longer function after installation.
• LiteSpeed is not compatible with NGINX With Reverse Proxy.
• After purchase, the system automatically replaces Apache with LiteSpeed on ports 80 and 443.

2. Choosing a LiteSpeed License Tier

WebPros offers two LiteSpeed license tiers:

• LiteSpeed 8GB — 8GB RAM limit and one worker process
• LiteSpeed Unlimited — Unlimited RAM and three worker processes

RAM Limit:

If your server has more than 8GB of RAM, you must use the Unlimited license.

Worker Processes:

Each worker runs one LiteSpeed process. More workers allow higher CPU usage and performance.
