This instruction applies to both LSWS and LSLB. For LSLB, just replace with “lslb” where “lsws” is used, and the binary is “lslbd” instead of “lshttpd”.

Notes:

• SERIAL_NO will be sent to you in the automated email upon your invoice paid. We recommend Copy & Paste instead of typing to avoid mistake. Save the serial number, minus quotes, as a file named “serial.no”. If you do not have the email as your mail server may block it, You can also find it on store - client area - my products. (Please resolve this ASAP by fixing it or changing to a different email. Otherwise you will not receive invoice email.)
• Remove all the old license related files before you register a new one. If you have old “serial.no”, “license.key” or “trial.key” under lsws/ or lsws/conf directories, please back up first and remove all of them from those directories.
• Please make sure license.litespeedtech.com is reachable from your server.
• If it fails to get a license key due to it's been used on a different server, you can release the license (refer to Transferring Or Releasing A License).
• If you still cannot register a license key by following all the instructions, please create a ticket with license department from online store - client area.

• Assuming LSWS has been installed to directory /usr/local/lsws, you just do the follow steps to activate the new license key purchased.

cd /usr/local/lsws

echo "SERIAL_NO" > conf/serial.no
bin/lshttpd -r

If license key has been registered successfully, you will see a new “license.key” under conf/, you can verify your new key with command

bin/lshttpd -V
