In this description, we will create a newer, Debian 11 (Bullseye) version of the perfect server. Unlike the previous perfect server installations, this time we will not do this with lengthy package installations and configurations, but with the help of an automation script, which the developers of ISPConfig have put together to facilitate the preparation of the server. The script has been available for some time, with the help of which it can be used not only on the Debian 11 (Bullseye) operating system, but also on the Debian 10 version, as well as on Ubuntu 20.04 and Ubuntu 22.04 systems. I automated the components of the perfect server.

PHP sessions are global variables that transmit data stored during web visits across multiple pages, i.e., they are not lost when moving from one page to another. PHP accomplishes this by assigning unique IDs to visits (sessions) and creating files in the server-side file structure associated with those IDs in which it stores the data required for the session. The system places these files in a specific directory, usually tmp, which is normally deleted by the garbage collector after a specified time. However, the situation is sometimes not so obvious. This is because if the PHP environment on the server changes, the garbage collector may not be able to delete these obsolete, unnecessary session files. In this description, we will look at how we can use our own solution to ensure that these session files are deleted when the default cleaning system cannot remove them.
