Question

You’ve been asked to install a new service called explodingwidgets. After installing the explodingwidgets package, what is the most likely way you would start the service?

Linux/ Unix Server

Answer 1

In Linux/Unix Server, after you have installed the new service called explodingwidgets package (software or application software), to start the service, you run it or execute (technically) it. When any user software application package is installed, it is not started by default, you need to manually start or run it. Since it is a server, there would not be a Graphical User Interface (GUI) to simply click on the icon of the package showing up anywhere on the desktop screen, the dock with your favorites applications, or the Applications wizard or section. You would need to use a Linux Command Line Interface (CLI) tool or Terminal. Open Terminal tool. You would need to type in a single command at the command prompt. The command would be a single line and a single word with the package's name. The package should start the service.

The command being:

sudo systemctl start service

or

sudo service explodingwidgets start

where service is the name of the application package. This command would prompt to type in the administrator's or the root password for the server since 'Sudo' is being used.

Or in case, there is an appropriate GUI for the particular Linux distro, then click the application’s icon to launch it, running it, and start the service.

Or, The application would have its icon in the dash, the vertical or horizontal strip of icons on any of the four corners or sides of the screen. Click the icon to start the application.

Or, to quickly run a command to launch the package, press Alt + F2 keys simultaneously, type in the package's command name, and press the 'Enter' key on the keyboard.

For example, in this case, to launch explodingwidgets, press Alt + F2 and type ‘explodingwidgets’, without the single-quotes (all one word). The name of the app or the package would be the command to launch the program.

Or, on a Linux client machine, you could start the package or launch the application package with the mouse. You would find the application package in the "Applications" section or wizard.
