Of course, you can. Just add the NethServer’s repositories in your CentOS, and start installing NethServer base system and the required modules (such as Web server, mail server, and more) you want to use. It is always recommended to use freshly installed CentOS minimal server to install NethServer.

Hardware requirements

To deploy NethServer, you need at least the following specification.

  • 64 bit CPU (NethServer is not available for 32 bit systems);
  • 1 GB RAM;
  • 8 GB free disk space. It is recommended to use at least two disks with RAID 1 configuration;
  • Since it is based on CentOS/RHEL, it will work on any hardware certified by Red Hat.

Install NethServer 6.8

As of writing this guide, the latest stable version was 6.8, and it is based on CentOS 6.8.

NethServer can be installed in two methods.

  1. Install using ISO,
  2. Install using YUM on an existing CentOS minimal system.

Install NethServer using ISO

Installing NethServer using ISO is opt for newbies and intermediate users. Download the latest stable version from the link given below.

Once downloaded, write the ISO to any CD/DVD or make a bootable USB drive as the way described in the following link.

Then, start the machine using the bootable media.

You will be greeted with the following screen.

As you see in the above screenshot, there are  different types of installation menus.

  1. NethServer interactive install – It needs the user interaction. I.E you have to select the language, configure RAID support, network, and encrypted file system etc.
  2. Other installation options – User interaction is not required. The installer will take care of everything, and the default parameters will applied.
  3. Standard CentOS installations – It allows the user to deploy the NethServer as the you do the normal CentOS installation.
  4. Tools – It allows users to go to system recovery, execute a memory test etc.
  5. Boot from local drive – Allows the users to boot the already installed OS.

I go with the first installation option i.e NethServer interactive install.

Choose the installer language:

Select the Network interface card to configure:

Enter the parameters for your Network card, such as IP Address, Netmask, Gateway, and DNS etc.

Select Install button to start the installing process. As you see in the below screenshot, the “root” user’s default password is “Nethesis,1234. You can change it later.

NethServer base system installation will start now.

Once the installation is completed, the system will automatically reboot.

At the boot prompt, enter the default username and password. The default username and password for both interactive and non-interactive installation mode is given below.

  • Default username : root
  • Root password : Nethesis,1234

Congratulations! NethServer base system has been successfully installed!!

If you chose non-interactive mode(unattended installation), the system will be automatically configured as shown below.

  • Default User name: root
  • Root password: Nethesis,1234
  • Network: DHCP enabled on all interfaces
  • Keyboard: en
  • Time zone: Greenwich
  • Language: English
  • Disks: if there are two or more disks, a RAID 1 will be created on first two disks.

You can change these values in the NethServer’s dashboard later.

NethServer initial configuration

First things first

The first thing we must do after installing any operating system is to update it.

To update your NethServer, run:

yum update

Once updated, reboot your system to apply all updates.

Then, change the default password to something else strong and hard to guess.

To do so, run:

passwd root

Sample output:

Changing password for user root.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.

We can also change the root user password from NethServer’s dashboard. We will see it in our upcoming articles.

Acesss NethServer’s Server-manager

To access the Server-manager, navigate to https://domain-name:980 or https://IP_Address:980 from your web browser.

You should see the following screen. Enter the default username and password – root/Nethesis,1234

Click Next.

Enter new root user password.

Enter NethServer’s hostname and domain name:

Enter your time zone:

Change the default SSH port to any random number (Do not forget the number though):

Click Next:

Review the changes and click Apply to configure NethServer.

Here it is how NethServer’s dashboard looks like.

That’s it. From here, you can do all administrative tasks, such as installing, removing, configuring modules, configure and manage network services, configure NethServer etc.

That’s all for today folks. In our upcoming tutorials, we will see how to:

  1. Install NethServer using YUM in a CentOS minimal server
  2. Install and configure modules in NethServer

Until then, stay tuned with OSTechNix.
