Linux | Guidelines for setting up a Linux Server as a VM

These are just plain guidelines for setting up a Linux server as a virtual machine. As time passes I keep seeing the same mistakes from fellow admins, over and over again so I decided to mention some of it.

Feel free to add anything else in the comments or point me out should I am making a mistake somewhere along the way ;)

First things first, you have to decide what will be the use of the VM that you are creating? Will it be a file server, or a web server, or a database server? Perhaps it will be a dedicated VM for a couple of users. No matter your choice, if you are setting up the server as a virtual machine in you infrastructure you have to keep in mind a few things so these are just a few golden rules for setting up a Linux VM so that you don't end up crying later when things go bad.

CentOS 7 | Installation and setup of Icinga2 monitoring service - Part 2 - Setting up the Icinga Web 2 interface

This is part 2 of the tutorial where I'll be setting up the Icinga Web 2 web fronted from where we can log into our Icinga2 server and actually monitor our infrastructure.

If you came here from Google than you can find Part 1 here.

CentOS 7 | Installation and setup of Icinga2 monitoring service - Part 1

Knowing that there is a newer fancier Nagios fork called Icinga I always wanted to try it out, but
I really haven't got the time to do that. Finally when I got the time I realized that online guides for that are missing too. Being a CentOS supporter, I decided that during that process i could write a tutorial for CentOS 7.

This is the part 1 of the tutorial where I'll be going through the steps for preparing the server and setting up the Icinga2 service. In part two I'll be going through the steps for installing and setting up the Icingaweb2 web service which basically is one of the several available Incinga2 front-end applications.
