How to update RHEL 7.4 to 7.5

The procedure to upgrade or update RHEL from version 7.4 to 7.5 is as follows:

  1. Login as root user
  2. Check for updates using the yum check-update command
  3. Update the system using the yum update command
  4. Reboot the server/box using the reboot command
  5. Verify new kernel and updates

Let us see all steps in details:

Step 1 – Note down the current kernel version

Type the following uname command or cat command to view RHEL kernel version and OS info:
$ uname -a
$ uname -r
$ cat /etc/os-release

Step 2 – Backups

Make a backup – it cannot be stressed enough how important it is to make a backup of your system before you do this. Most of the actions listed in this post are written with the assumption that they will be executed by the root user running the bash or any other modern shell.

Step 3 – Check for updates

$ sudo yum check-update

Step 4 – Apply/install updates

Type the following yum command:
$ sudo yum update -y

Step 4 – Reboot the RHEL 7.4 box

    Hi Vivek,

    We have couple of red hat VMs with 7.6 version and due to some vulnerabilities Security Team suggested them to upgrade to 7.8.
    How can I perform this upgrade from 7.6 to 7.8??

    Thanks in advance,
    Suresh Bichhali

    Nice, thanks for tips!
    In a Azure VM RHEL (eg. RHEL 7.4 to 7.5) i needed to change the file:
    $ echo 7.5 > /etc/yum/vars/releasever
    $ sudo yum check-update
    $ sudo yum update -y

    I didn’t quite get in the instructions how do you specify that from 7.4, u want to upgrade to 7.5 or how about 7.6?

    Wow -as a tenured linux admin who stumbled across this, there is a whole lot of information missing on how to update a system from one dist version to the other. Im also shocked at the replies from others telling people that the “commands are the same” to just upgrade your dist two minor dists up like nothing could go wrong.
