= Enabling SELinux
|
|
|
|
When enabled, SELinux can run in one of two modes: enforcing or permissive. The following sections show how to permanently change into these modes.
|
|
|
|
While enabling SELinux on systems that previously had it disabled, to avoid problems, such as systems unable to boot or process failures, follow this procedure:
|
|
|
|
. Enable SELinux in permissive mode. For more information, see <<{context}-changing-to-permissive-mode>>.
|
|
|
|
. Reboot your system.
|
|
|
|
. Check for SELinux denial messages.
|
|
// For more information, see <<Fixing_Problems-Searching_For_and_Viewing_Denials>>.
|
|
|
|
. If there are no denials, switch to enforcing mode. For more information, see <<{context}-changing-to-enforcing-mode>>.
|
|
|
|
To run custom applications with SELinux in enforcing mode, choose one of the following scenarios:
|
|
|
|
* Run your application in the `unconfined_service_t` domain.
|
|
// See <<Targeted_Policy-Unconfined_Processes>> for more information.
|
|
|
|
* Write a new policy for your application. See the link:++https://access.redhat.com/solutions/117583++[Writing Custom SELinux Policy] Knowledgebase article for more information.

|
|
|
// Temporary changes in modes are covered in <<{context}-selinux-states-and-modes>>.
