CentOS 6.3 DNS Server Master&Slave Setting

安裝DNS套件：Master&Slave 都要裝Bind、Bind-chroot

0. Master：

[root@node1 /]# yum install bind bind-chroot                        //安裝DNS套件

[root@node1 /]# vim /etc/named.conf                                    //修改DNS設定檔

將底下兩行MARK，不然只有local可以listen

#listen-on port 53 { 127.0.0.1; };

#listen-on-v6 port 53 { ::1; };

allow-query     { any; };                                                         //允許所有人來查

………….

zone "master.com.tw" IN {

        type master;

        file "named.master";

        allow-transfer { 192.168.1.2; };                                 //允許轉送

        notify yes;                                                                  //自動更新

        also-notify { 192.168.1.2; };                                       //自動更新至slave

};

zone "1.168.192.in-addr.arpa" IN {

        type master;

        file "named.192.168.1";

        allow-transfer { 192.168.1.2; };                                 //允許轉送

        notify yes;                                                                  //自動更新

        also-notify { 192.168.1.2; };                                       //自動更新至slave

};

2.Slave：

      [root@node2 /]# yum install bind bind-chroot //安裝DNS套件

[root@node2 /]# vim /etc/named.conf

zone "ecbo.com.tw" IN {

        type slave;

        masters { 192.168.1.1; };

        file "slaves/named.master";                   //檔案路徑

        allow-notify { 192.168.1.1; };                  //自動接收Master更新

};

zone "1.168.192.in-addr.arpa" IN {

        type slave;

        masters { 192.168.1.1; };

        file "slaves/named.192.168.1";              //檔案路徑

       allow-notify { 192.168.1.1; };                    //自動接收Master更新

};

3.將nameserver指為自己

[root@node1 named]# vim /etc/resolv.conf

nameserver 192.168.1.1

4.重啟named 就會同步到 Slave

service named restart
