• Trial — web server trial license.

   

The following buttons are available to manage the license:

• Enter LiteSpeed license key — calls a form for entering a license key. The button is not displayed if ispmanager is specified in the License type.

Onve the web server is activated, the key is stored in the serial.no file in the /usr/local/lsws/conf/ directory. To display information about the license, use the /usr/local/lsws/bin/lshttpd -tcommand in the terminal.

Once a day, the panel automatically checks the connected license. If there are less than 5 days left until its expiration, the administrator will receive a notification in the ispmanager panel. The number of days and the frequency of checking can be changed in the litespeed.conf file in the /usr/local/mgr5/etc/ispmgr.conf.d/ directory.
