Installing CentOS Stream 9

If your system meets all the requirements and you are okay with changes to CentOS Stream, we can process the installation. Let’s start with Downloading ISO and booting.

Step 1: Downloading CentOS Stream 9 ISO

First, visit its official page to download CentOS Stream 9. Once you are done with the download part, you can use any USB bootable tool such as Rufus, balenaEtcher, or Ventoy for flashing it on your drive (for bare-metal installation).

Now, boot from your bootable drive, and you will meet with the following screen. Choose the first option which will start the installer.

Step 2: Choose Installer Language

CentOS Stream uses the Anaconda installer which is one of the rare installers which has a separate prompt just for selecting installer language. You can choose what comforts you the most but for the majority, English will be the correct option and we are going with that.

Step 3: Setting Up Localization

In this step, we are going to configure all the available options under the Localization section which are Keyboard, Language Support, and Time & Date. Let’s Start with Keyboard.

Select Keyboard Option.

Now Click on Language Support where we can choose additional languages required by the user to work.

CentOS Stream Language Support

From here you can choose the additional language you want to get supported on your system. I only use English so I’m going with default options.

Select the last option in Localization labeled “Time & Date” to choose our region.

Form here, choose your region and city and click on Ok.

Step 4: Setting Up Software Options

In this step, we are going to choose the software required for our system. We will not make any changes to the installation source as it will automatically detect the local media. So let’s start with the Software selection.

Click on the 2nd option labeled as “Software Selection”.

Step 4: Choose Installation Drive

Click on Installation Destination which will direct us to the available disks.

CentOS Stream Installation Destination

Select the desired disk. You have two options for partitioning your drive: manual and automatic. We would suggest automatic partitioning as it handles the size well but if you want to customize partitions, you can choose the other option.

Step 6: Setting Network and Hostname

In this step, we are going to allocate the hostname to our system including setting up networking. Click on “Network & Hostname”.

CentOS Stream Network

If you are using Ethernet, you just have to enable it by the given button. To allocate the hostname, you are given a separate section. In my case, I’m going to use tecmint.

CentOS Stream Network Configure

In case you are not using DHCP, click on Configure which will direct us to set up our network manually. From here, click on Ipv4 and choose the Manual method. Add your desired Address, Netmask and Gateway by clicking on Add button. In the end, add DNS and save the configuration.

CentOS Stream User Account

Enter details such as Full name, password, etc. If you want, you can make this user administrator by giving the option. We always recommend you use a strong password.

Once you are done with adding a user, Select “Root Password” which will allow us to create a root password for our existing user.
