This guide walks through the detailed steps to install a 64-bit version of the Rocky Linux distribution on a stand-alone system. We will be performing a server class install using an operating system installer image downloaded from the Rocky Linux project website. We will step through the installation and customization steps in the following sections.


## OS Installation Prerequisites

First, you need to download the ISO to be used for this installation of Rocky Linux.

The latest ISO image for the version of Rocky Linux that we will be using for this installation can be downloaded from here:

```
https://www.rockylinux.org/download/
```
<https://www.rockylinux.org/download/>

To download the ISO directly from the command line, use the `wget` command:

```
```bash
wget https://download.rockylinux.org/pub/rocky/8.9/isos/x86_64/Rocky-8.9-x86_64-minimal.iso
```

Rocky Linux ISOs are named following this convention:

```
```text
Rocky-<MAJOR#>.<MINOR#>-<ARCH>-<VARIANT>.iso
```

First download the file that contains the official checksums for the available ISOs. While still in the folder that contains the downloaded Rocky Linux ISO download the checksum file for the ISO, type:

```
```bash
wget https://download.rockylinux.org/pub/rocky/8.9/isos/x86_64/CHECKSUM
```

Use the `sha256sum` utility to verify the integrity of the ISO file against corruption and/or tampering.

```
```bash
sha256sum -c CHECKSUM --ignore-missing
```

This will check the integrity of the previously downloaded ISO file, provided it is in the same directory. The output should show:

```
```text
Rocky-8.9-x86_64-minimal.iso: OK
```

A quick media verification step will take place. This media verification step can save you the trouble of starting the installation only to find out halfway through that the installer has to abort because of bad installation media.

After the media check runs to completion and the media is successfully verified to be usable, the installer will automatically continue to the next screen.
