Control Your SELinux

SELinux can be incredible powerful when used correctly. Out of the box though it's a bit too totalitarian.

Temporarily set mode to permissive (log and warn but not interrupt)

setenforce 0 

Make the change permanent by opening /etc/selinux/config and editing the line SELINUX line:


By default SELinux log messages are written to /var/log/audit/audit.log via the Linux Auditing System auditd, which is started by default. If the auditd daemon is not running, then messages are written to /var/log/messages . SELinux log messages are labeled with the "AVC" keyword so that they might be easily filtered from other messages, as with grep.
