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
...
}
