CentOS, a widely used Red Hat Enterprise Linux-based distribution, offers a stable and robust platform for all types of enterprise applications. 

However, a business can only realize the benefits that CentOS berings to processes and operations when they upgrade and maintain their OS to the latest update. At the time of writing this tutorial, the latest version is CentOS 7.9. 

CentOS 7.9, released in September 2020, brings enhanced features, improved support for modern software and server technologies, and security updates. 

However, note that the process we will describe in this tutorial can be used to update your current CentOS version to a newer one. However, you should always check the documentation to see the applicability of the process. 

So, in this tutorial, we will discuss how to update CentOS, specifically upgrading your CentOS 7.x system to version 7.9.

The Upgrade Process to CentOS 7.9: The 6 Easy Steps

We will now go into the details of the steps of the CentOS upgrade process. But before that, we would take a look at the prerequisites to the process.

The Prerequisites

  • A system running CentOS 7.x 
  • A user account with root or sudo privileges 
  • The YUM package manager (included by default in CentOS).

Note that you need to be logged in as the Administrator or a user with sudo privileges to execute the following steps. We recommend our tutorial on adding a user to the sudoers group to grant the required privileges. 

Step #1: Confirm Your Current CentOS Version

Start by verifying your current CentOS version by running the following command in the terminal:

# cat /etc/redhat-release

Ensure the version number begins with 7.x.x, indicating that you’re running CentOS 7.

For detailed instructions, refer to our guide to checking your CentOS version,

Step #2: Backup Critical Data

Before initiating an operating system upgrade, ensure all critical server data is backed up. Confirm the integrity and accessibility of your backups so that you can quickly resume operations in case of a disaster.

Step #3: Inspect Available Updates

Run the following YUM command to list available updates, including those for the core operating system:

# sudo yum check-update

The system will present a list of pending updates for the core operating system. Review this list to ensure all updates are appropriate and necessary.

While you are there, we recommend examining the list for software you’ve customized or manually installed. You may need to reinstall these packages after you finish updating the CentOS core OS files. 

Step #4: Clean the Package Manager

Clear out residuals and redundant data from the YUM package manager with this command:

# sudo yum clean all

Then, reboot the server to refresh the local YUM repository cache. This is an essential step for enhancing the update process and avoiding potential conflicts:

# reboot

Step #5: Perform the CentOS Update

Initiate the update process with the following command:

# sudo yum update

You will see a list of packages to be updated and the amount of disk space required. Confirm the update by pressing Y. This instructs YUM to proceed with the download and installation processes.

Step #6: Verify the Upgrade to CentOS 7.9

Confirm the upgrade success by checking the CentOS version again:

# cat /etc/redhat-release

The terminal should now display that CentOS Linux release 7.9 is running on your server.
