===Part 3: Disable SELinux and Perform Software Updates===
{{Admon/important|Never disable SELinux in the real world| It is highly discouraged and unsafe to disable SELinux on a public-facing server. Some applications may require tedious steps to setup SELinux rules. Disabling SELinux is never the correct way to solve an issue.}}
# Restart your VM.
# You can check the status of SELinux at any time at the command line by typing: '''sestatus'''
 
=== Part 4: Perform Software Updates===
 
Running software updates regularly is an important part of keeping your computer secure and stable. On Linux, we use package managers to install software and updates. Package managers not only perform installations, but they keep track of everything that is currently installed on the system for easy management. For CentOS, this manager is called yum. Yum is also the command used.
 
:'''Perform the following steps:'''
 
# Open Terminal
# Login as root (su -)
# Type: yum update
# Follow the prompts
# If there is a kernel update, reboot your system. (There usually is on a first update after OS installation)
