The first thing I do on a newly installed server is updating the system: Earlier dnf was used in Fedora distributions, and now it has come to CentOS 8. Install Updates & Administrator Tools on CentOSĪs mentioned earlier, dnf has replaced yum in CentOS 8.ĭnf – is the next generation of YUM application, an RPM package manager for Linux distributions. Configuring CentOS 8 Basic Settings after Installationīasic CentOS 8 post-install configuration is almost similar to that of CentOS 7, and I configure the same basic settings on all servers.

So the CentOS 8 installation is complete. When you see Reboot button on the installation screen, it means that the installation is over, and you must restart your server. The CentOS 8 installation has taken about 5-7 minutes. Then click Done to get back to the installation:

You can also create another user, but it is optional.Ĭlick Root Password, enter the password and confirm it. If you are going to use CentOS 8 as a server, it is enough to choose Minimal Install, as well as Standard and Guest Agents (if you install a guest OS on a virtual machine).Īfter doing that, you can start the installation by clicking Begin Installation.ĭuring unpacking and installing the required components, you will be prompted to enter a password for the root user.

Then you will have to click Reclaim space to update the size of the available disk space. You can remove the partitions by clicking Delete all. I removed the partitions of the previous operating system in the next menus that appeared: Since a guest OS had been installed on my virtual machine earlier, the installation saw it. If your server storage controller does not support a hardware RAID, you can configure a software RAID on your server disks using mdadm. The recommended minimum requirements for CentOS 8 installation are at least 10GB of disk space and 712MB RAM per CPU core. (If you want to install CentOS on a physical server, write the installation ISO image on a USB stick.) I will say that the CentOS 8 installation process does not differ from that of the previous version, and this article is intended as a guide for the users who do it for the first time. Since I installed the CentOS on a KVM virtual machine, I had downloaded an installation ISO image from one of the official mirrors ( ) in advance and mounted it to install the OS on a virtual server.
