With the help of LAMP systems, we can run dynamic web pages on our server or even on our home computer. I have previously built LAMP servers for Debian 8 (Jessie), Debian 9 (Stretch) and Ubuntu 18.04 LTS (Bionic Beaver), and in this description we will install the LAMP server components for the Ubuntu 20.04 LTS (Focal Fossa) Linux distribution.
Version 2020 of the ISPConfig web hosting control panel was released today (October 15, 3.2).

When you often need to run other commands as root using sudo, you may need to type the password every time. Although the session "remembers" the previously entered password for a while, we don't have to retype it for a while, but we need to re-identify ourselves after a while. Also, if you work with multiple users, you will need our passwords more often. And if you also want to use commands running with root privileges in Shell scripts, you definitely need to avoid typing passwords so that our programs can run automatically. In this short description, we will look at how to persistently avoid asking for a password when using sudo.
Drupal is an open source, free CMS (content management) system that can be used to build a wide variety of websites, such as this site.

In this short little troubleshooter, we'll look at how to remove these unnecessary index.php parts from URLs.
