I have completed the task by SSH on to [email protected] and installing the Selinux using the commands
yum install selinux-policy-targeted
yum install selinux-policy-devel policycoreutils
After that I checked sestatus and it was showing as disable on the stapp01 (stapp01.stratos.xfusioncorp.com). I came out of server by exiting from stapp01 terminal.
When I submitted the work, the task was unsucessfull.
