When setting up a new Linux server, updating the system's Kernel and other packages to the latest stable release is a recommended practice.
In this article, we will learn how to update CentOS 7, Ubuntu 16.04 LTS or Debian 8.
Setup the EPEL YUM repo:
sudo yum install epel-release -y
Perform the system update and then apply system modifications by restarting the system:
sudo yum update -y && sudo shutdown -r now
Update the list of packages which can be updated:
sudo apt-get update -y
Then install updates and then apply them by restarting the system:
sudo apt-get upgrade -y && sudo shutdown -r now
That's it. After the reboot, log in as the same sudo user to continue your work.
