SELinux is based on the least level of access required for a service to run. Services can be run in a variety of ways; therefore, you need to specify how you run your services. Use the following Booleans to set up SELinux:
- When disabled, this Boolean prevents
namedfrom writing to zone files or directories labeled with the
named_zone_ttype. The daemon does not usually need to write to zone files; but in the case that it needs to, or if a secondary server needs to write to zone files, enable this Boolean to allow this action.
- When enabled, this Boolean allows BIND to bind an Apache port.
Due to the continuous development of the SELinux policy, the list above might not contain all Booleans related to the service at all times. To list them, enter the following command:
~]$Enter the following command to view description of a particular Boolean:
getsebool -a | grep service_name
~]$Note that the additional policycoreutils-devel package providing the
sepolicy booleans -b boolean_name
sepolicyutility is required for this command to work.
