Install NethServer using YUM in CentOS
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.
Let us get started.
Install NethServer using YUM in CentOS minimal server
Please note that you should install NethServer in a fresh CentOS minimal server.
Log in as root user, and update the CentOS server using command:
Then, run the following command to add and enable NethServer’s repository in your CentOS:
yum localinstall http://mirror.nethserver.org/nethserver/nethserver-release-6.rpm
yum localinstall http://mirror.nethserver.org/nethserver/nethserver-release-6.rpm Loaded plugins: fastestmirror Setting up Local Package Process nethserver-release-6.rpm | 24 kB 00:00 Examining /var/tmp/yum-root-Lmn3jM/nethserver-release-6.rpm: nethserver-release-6.8-2.ns6.noarch Marking /var/tmp/yum-root-Lmn3jM/nethserver-release-6.rpm to be installed Loading mirror speeds from cached hostfile * base: centos.excellmedia.net * extras: centos.excellmedia.net * updates: centos.excellmedia.net Resolving Dependencies --> Running transaction check ---> Package nethserver-release.noarch 0:6.8-2.ns6 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: nethserver-release noarch 6.8-2.ns6 /nethserver-release-6 42 k Transaction Summary ================================================================================ Install 1 Package(s) Total size: 42 k Installed size: 42 k Is this ok [y/N]: y

The above commands will download and install NethServer packages in your CentOS server. This will take a while depending upon the Internet connection speed.
Finally, you will see the following message after NethServer base system has been installed.
