Litespeed requires you to download the Trial key to try out their trial or use the WHM to do that. If you want to skip the process and fan of console, here is the easiest way to do this step by step:
$ cd /usr/local/lsws/conf $ service lsws stop $ mv trial.key trial.key_backup $ wget --no-check-certificate https://license2.litespeedtech.com/reseller/trial.key $ chown root:nobody trial.key $ service lsws start $ /usr/local/lsws/bin/lshttpd -t [OK] Your trial license key will expire in 14 days!
Remember, this can only be done twice, the first month only. So you would definitely like to purchase the license and register it with the purchased key after your trial ends. Kudos!
