Selinux serurity

To meet the security requirements for SELinux on App Server, follow these steps:

If SELinux is not installed, install it using:

sudo yum install -y selinux-policy selinux-policy-targeted

For RHEL/CentOS systems.

Or for Debian/Ubuntu-based systems:

sudo apt install -y selinux-utils policycoreutils selinux-policy-default

Modify the SELinux configuration file to disable SELinux:

sudo sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config

Alternatively, manually edit the file:

sudo nano /etc/selinux/config

Change the line:

SELINUX=enforcing

To:

SELINUX=disabled

Save and exit.

Since no immediate reboot is required, verify that SELinux is set to be disabled after the next reboot:

grep SELINUX= /etc/selinux/config

The output should show:

SELINUX=disabled

Once the maintenance reboot occurs, SELinux will remain disabled as per the configuration.
