4、chkconfig -level=$l networkmanager /dev/null 2 then networkmanagerenabled=1; fi; done if $networkmanagerenabled -eq 1 ; then options= $options -d fi; dbusenabled=1; fi start() start daemons. echo -n $ starting $named: if -n pidofnamed ; then echo -n $ $named: already running failure echo return 1 fi

5、 /usr/local/bind/sbin/named -n 1 -uroot -c /usr/local/bind/etc/named.conf retval=0 if $retval -eq 0 ; then ccess ee failure fi; echo return $retval stop() stop daemons. echo -n $ stopping $named: $rootdir/sbin/rndc stop /dev/null 2 1 retval=$? $retval -eq 0 | proc -p $rootdir/etc/named.pid $named -t

7、ed return $? restart() stop wait a couple of seconds for the named to finish closing down sleep 2 start reload() echo -n $ reloading $named: p=pidofnamed retval=$? if $retval -eq 0 ; then $rootdir/sbin/rndc reload /dev/null 2 1 | /bin/kill -hup $p; retval=$? fi $retval -eq 0 success $ $named reload

8、| failure $ $named reload echo return $retval probe() named knows how to reload intelligently; we dont want linuxconf to offer to restart every time $rootdir/sbin/rndc reload /dev/null 2 1 | echo start return $? checkconfig() ckcf_options=-z; named-checkzone for each zone (9.3.1+) ! if -n $rootdir -a x$rootdir != x/ ; then options= $options -t $rootdir ckcf_options= $ckcf_options -t $rootdir fi; if -x $rootdir/sbin/named-checkconf -x $rootdir/sbin/named-checkzone ; then return 0; else return 1; fi see how we were calle
