Bind9 名称服务器从服务器存在主文件传输问题

Question

我已设置了主名称服务器，现在尝试配置从属名称服务器。Bind9 似乎加载并运行良好，但我收到以下错误：

Apr 27 12:47:21 ns2 named[23563]: dumping master file: slaves/tmp-oJ5LJ1RtO4: open: file not found

这是我的 named.conf.options 文件：

options {

recursion yes;
allow-recursion { trusted; };
listen-on { 10.0.1.11; }; //this machines IP. 
allow-transfer { none; };

// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk.  See http://www.kb.cert.org/vuls/id/800113

// If your ISP provided one or more IP addresses for stable 
// nameservers, you probably want to use them as forwarders.  
// Uncomment the following block, and insert the addresses replacing 
// the all-0's placeholder.

forwarders {
    10.0.1.12;
    x.x.x.x; //keeping my ISPs nameservers private for post in askUbunutu
    x.x.x.x; //
};

//========================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys.  See https://www.isc.org/bind-keys
//========================================================================
dnssec-validation auto;

auth-nxdomain no;    # conform to RFC1035
listen-on-v6 { any; };

};

从属named.conf.local文件：

//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";
zone "mycity.example.com" {
type slave;
file "slaves/db.mycity.example.com";
masters { 10.0.1.12; };
};

zone "1.0.10.in-addr.arpa" {
    type slave;
    file "slaves/db.10";
    masters { 10.0.1.12; };
};

/etc/bind/slaves 的目录权限

drwxr-sr-x   2 bind bind  4096 Apr 27 09:41 slaves

知道我做错了什么吗？

Answer 1

文件指令与 ubuntu 上的 bind var 目录相关，默认为以下内容：

/var/缓存/绑定

除非使用选项中的目录指令进行更改，否则它会寻找以下目录来保存数据：

/var/缓存/绑定/从属

请注意，这可能是一个更好的位置，无论如何，授予 bind 对其自己的 /etc 目录的写访问权限并不理想，因为这样做允许某人以某种方式利用 bind 更安全的方式将变量数据保存在其他地方并让服务器在那里写入，从而潜在地更改您的 bind 配置。
