示例1: RunDNSServer

// RunDNSServer starts the DNS server
func (c *MasterConfig) RunDNSServer() {
	config, err := dns.NewServerDefaults()
	if err != nil {
		glog.Fatalf("Could not start DNS: %v", err)
	}
	config.DnsAddr = c.Options.DNSConfig.BindAddress
	config.NoRec = true // do not want to deploy an open resolver

	_, port, err := net.SplitHostPort(c.Options.DNSConfig.BindAddress)
	if err != nil {
		glog.Fatalf("Could not start DNS: %v", err)
	}
	if port != "53" {
		glog.Warningf("Binding DNS on port %v instead of 53 (you may need to run as root and update your config), using %s which will not resolve from all locations", port, c.Options.DNSConfig.BindAddress)
	}

	if ok, err := cmdutil.TryListen(c.Options.DNSConfig.BindAddress); !ok {
		glog.Warningf("Could not start DNS: %v", err)
