Environment

Performance Management 22.2.5 

Cause

SELINUX was enabled 

Resolution

To permanently disable SELINUX

1.  To disable selinux edit its configuration file by typing, as root:
vi /etc/selinux/config and Enter.  A vi edit view will appear. 

2.  Type i to begin editing.  The up, down, left & right arrows must be used to navigate through this configuration. 

3.  Change the line: SELINUX=enforcing to SELINUX=disabled.  Hit the Esc key once, while holding Shift press the : (colon) key once and release. 

4.  Now type wq and hit Enter; this will write the changes to the file.  To exit without making any changes, instead of wq type q! and hit Enter.

5.  Reboot
