If you want to manage the port for a daemon that is started/stopped via
an init script, then the best place to put the 'semanage port -a ...'
command is in the init script itself. This will ensure that the port
definition is set and removed when the daemon starts/stops. Putting it
in the spec file and running at package install time is not enough
because I don't believe that the semanage'd ports persist after a reboot.
start() {
...
if selinuxenabled ; then
/usr/sbin/semanage port -a -t memcached_port_t -p tcp 12111
&>/dev/null || :
fi
...
}
stop() {
...
if selinuxenabled ; then
/usr/sbin/semanage port -d -t memcached_port_t -p tcp 11211
&>/dev/null || :
fi
...
}
--Wart
