In our previous guide, we have seen what is NethServer and how to install NethServer by using its ISO image. It was the easiest and straight forward method. Today, we will see how to install NethServer in an existing, freshly installed CentOS server. If you have a VPS or physical system pre-installed with CentOS operating system, you can install NethServer on top of it, without formatting or deleting the entire setup.
