How to install PHP 7.4 on Ubuntu 22.04 LTS Jammy Linux
By default system repository Php 8.1 is available to install on Jammy JellyFish, hence in this tutorial, we learn the commands to install PHP 7.4 on Ubuntu 22.04 LTS server or desktop using the terminal.
PHP is a scripting language, so it is translated line by line into machine commands by an interpreter. On the Internet, PHP is behind over 80% of all websites on whose web servers it runs and thus controls the behavior of the website. It has been used by many web servers such as Apache to power thousands of websites and web platforms. Also, PHP makes it easy for programmers to develop and control a website functioning because PHP has numerous function libraries and connections to Internet protocols and databases.
Further, PHP can be used to process user input. If, for example, you want to include a contact form on your website, the entries must be further processed. Only with HTML, this is not possible. With PHP, for example, you can check whether all fields have been filled in and, if successful, send an e-mail. Also, when it comes to retrieving content from a database, it makes sense to use PHP. For example, if you want to program a news website, you can save your texts in a database and then output them with PHP at the desired places in your HTML code. You do not have to create a single HTML file for each article and can implement changes much faster. That’s why PHP has been used for creating Dynamic websites.

How to Install and Configure Puppet 7 Server on Ubuntu 22.04
In this guide, we are going to install Puppet 7 Server Open Source in Ubuntu 22.04. We will set up a Puppet server and an agent and install Nginx using puppet manifests.
Puppet is a software configuration management tool which includes its own declarative language to describe system configuration. It is a model-driven solution that requires limited programming knowledge to use. Puppet operates in an agent-master architecture, in which a master node controls configuration information for a fleet of managed agent nodes.
Puppet is distributed in several packages. These include puppetserver, puppet-agent and puppetdb. Puppet Server controls the configuration information for one or more managed agent nodes. PuppetDB is where the data generated by Puppet is stored.
