Bind9无法启动，rndc连接失败

Question

我安装了virtualmin并播放DNS设置。现在，当我尝试启动bind9时，我得到了错误：

Service bind9 restart

 * Stopping domain name service... bind9   
   rndc: connect failed: 127.0.0.1#953: connection refused
                                                                    [ OK ]
 * Starting domain name service... bind9                            [fail]

Answer 1

这个错误信息其实是很清楚的。正如named.conf(4)中所记录的那样，选项transfer-source必须后面跟着一个IPv4地址或令牌*，而配置的第26行中只有bare关键字：

transfer-source;

修复它，错误就会消失。

您在named.conf中的配置有问题：

Oct 11 06:05:45 stock named[6316]: /etc/bind/named.conf.options:26: expected IPv4 address or '*' near ';'
Oct 11 06:05:45 stock named[6316]: loading configuration: unexpected token

如果在Windows上编辑named.conf，则必须将named.conf格式转换为Unix格式。您可以从Linux中使用dos2unix。
