This guide was created with the following products:
(Details may vary with products from different providers but the main concepts remain the same)
Introduction
The following will explain to you step by step how to install and configure the CentOS operating system on your dedicated server. Follow these instructions carefully to ensure that you set up the operating system successfully and utilize it optimally.
The structure of the guide is based on the use of the CentOS 8.3 operating system. Installations from previous or newer versions may differ slightly in terms of the process.
Preparation
For the installation and configuration of an operating system, it is initially important to mount the corresponding ISO of the operating system. There are several possible ways to mount it:
- Mounting via the initial setup
- Mounting via iLO (Virtual Media)
- Mounting via iLO (Remote Console)
If you are not familiar with mounting an ISO file yet, it's best to refer to our Initial setup or Own ISO guide.
Installation
When the ISO is successfully loaded, the server is in the setup process.
-
Keyboard Choose your preferred keyboard layout
-
Time & Date Choose your timezone
-
Root Password Set a password for your root account. This can be any, but remember to use a strong password and save it on a safe place.
-
Installation Destination Select the SSD where CentOS will be installed
-
Network & Hostname Since there is an incompatibility issue, the network could not be setup yet, we will do this in the end.
Once you've configured all settings to your liking, press 'Begin Installation.
After the installation is complete, remove the ISO file from your server and click 'Reboot System'.
Configuration
Network
Next, we'll configure the network device, which requires updating some files. Please mount this ISO File into your server, through the remote console or the iLO itself.

After the ISO File was mounted successfully, we need to mount it into our system, to have access to it.
mount /dev/sr0 /mnt
The ISO-file is now mounted at /mnt
rpm -i /mnt/be2net.rpm
Next, install the update package.
modprobe be2net
In this step, we will run the update, this could take a few seconds.
You can now check with ip a s if a network device called eno1 exists, if yes, please reboot your system.
After the system has rebooted, proceed to configure the network device.
nano /etc/sysconfig/network-scripts/ifcfg-eno1
Please fill in the following data into the file:
DEVICE=eno1
BOOTPROTO=dhcp
ONBOOT=yes
You can leave nano by pressing CTRL+X and Y
Now we need to start our network device with ifup eno1
Your dedicated server should now have a working internet connection.
