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:

yum update

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

Sample output:

yum localinstall http://mirror.nethserver.org/nethserver/nethserver-release-6.rpm
 Loaded plugins: fastestmirror

rootserver_020

Finally, install NethServer base system using command:

nethserver-install

Sample output:

rootserver_021

Alternatively, you can install base system and additional modules (Ex.Mail server) at the same time as shown below:

nethserver-install nethserver-mail nethserver-nut

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.

Complete!

Configuring system, please wait...

You can access the Web interface at:

 https://domain-name:980 (or https://IP_Address:980)

Acesss NethServer’s Server-manager

You can access the NethServer web interface by reaching the following URL(s) from your web browser.

  • https://domain-name:980 or https://IP_Address:980

Log in as your root user and its password.

example-org-login-chromium_023

Click Next to continue.

example-org-firstconfigwiz_title-chromium_024

Enter your NethServer’s hostname and domain name.

example-org-firstconfigwiz_title-chromium_025

Enter your Time zone:

example-org-firstconfigwiz_title-chromium_026

As we all know, the SSH service by default uses port 22. Using this value does not make your system insecure, however, changing the default SSH port will stop many automated attacks. Change to to any random port (don’t forget the port no) and click Next.

example-org-firstconfigwiz_title-chromium_027

You can send your NethServer’s usage statistics to developers if you like. The collected data will send sent as anonymous form. Only the IP address and release number will be collected.

Click Next to continue.

example-org-firstconfigwiz_title-chromium_028

Finally, review the changes and click Next to continue.

example-org-firstconfigwiz_title-chromium_029

Congratulations! NethServer has been configured!

This is how NethServer’s dashboard looks like.

example-org-dashboard-chromium_030

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 now folks. In our next article, we will see how to,

      You can’t install NethServer on CentOS 32 bit version. NethServer works on 64 bit platforms only.
