主从DNS配置流程示例

实验环境：主服务器A：10.1.1.6
                    从服务器B：10.1.1.5
1.安装DNS域名解析服务
  #yum install bind-* -y
2.主服务器A配置：
  #vim /var/named/chroot/etc/named.conf
     options {
             directory "/var/named";
             allow-recursion {10.1.1.5/24; };
     };
     #zone "."  IN {
     #       type hint;
     #       file "named.ca";
     #};
     #zone "localost" IN {
     #       type master;
     #       file "named.localhost";
     #       allow-transfer {none; };
     #};
     #zone "0.0.127.in-addr.arpa" IN {
     #       type master;
     #       file "named.loopback";
     #       allow-transfer {none; };
     #};
     zone "swht.com" IN {
             type master;
             file "swht.com.zone";
     #       masters {10.1.1.6; };
             allow-transfer {10.1.1.5; };
     };
     zone "1.1.10.in-addr.arpa" IN {
             type master;
             file "10.1.1.zone";
             allow-transfer {10.1.1.5; };
     };
  #chmod 640 /var/named/chroot/etc/named.conf  修改文件的权限
  #chown root:named /var/named/chroot/etc/named.conf 修改文件的属组
  #vim /var/named/chroot/var/named/swht.com.zone
     $TTL 600
     @               IN      SOA     master.swht.com.  root (
                                             2014091901
                                             1H
                                             5M
                                             2D
                                             6H)
                     IN      NS      master
                     IN      MX  10  mail
     master          IN      A       10.1.1.6
     mail            IN      A       10.1.1.6
     www             IN      A       10.1.1.6
     ftp             IN      CNAME   www
  #chmod 640 /var/named/chroot/var/named/swht.com.zone
  #chown root:named /var/named/chroot/var/named/swht.com.zone
  #vim /var/named/chroot/var/named/10.1.1.zone
     $TTL 600
     @               IN      SOA     master.swht.com.  root (
                                             2014091901
                                             1H
                                             5M
                                             2D
                                             6H)
                     IN      NS      master
     6               IN      PTR     master
     6               IN      PTR     mail
     6               IN      PTR     www
     6               IN      PTR     ftp
  #chmod 640 /var/named/chroot/var/named/10.1.1.zone
  #chown root:named /var/named/chroot/var/named/10.1.1.zone
  #service named restart
3.从服务器B配置：
  #vim /var/named/chroot/etc/named.conf
     options {
             directory "/var/named";
             allow-recursion {10.1.1.6/26; };
             notify yes;
     };
     #zone "."  IN {
     #       type hint;
     #       file "named.ca";
     #};
     #zone "localost" IN {
     #       type master;
     #       file "named.localhost";
     #       allow-transfer {none; };
     #};
     #zone "0.0.127.in-addr.arpa" IN {
     #       type master;
     #       file "named.loopback";
     #       allow-transfer {none; };
     #};
     zone "swht.com" IN {
             type slave;
             file "slaves/swht.com.zone";
             masters {10.1.1.6; };
     };
     zone "1.1.10.in-addr.arpa" IN {
             type slave;
             file "slaves/10.1.1.zone";
             masters {10.1.1.6; };
     };
  #chmod 640 /var/named/chroot/etc/named.conf
  #chown root:named /var/named/chroot/etc/named.conf
  #service named restart
4.验证：
  #dig -t NS www.swht.com
  #host 10.1.1.6
  #cd /var/named/chroot/var/named/slaves
  #ls
     10.1.1.zone  swht.com.zone
  #vim 10.1.1.zone
     $ORIGIN .
     $TTL 600        ; 10 minutes
     1.1.10.in-addr.arpa     IN SOA  master.swht.com. root.1.1.10.in-addr.arpa. (
                                     2014091901 ; serial
                                     3600       ; refresh (1 hour)
                                     300        ; retry (5 minutes)
                                     172800     ; expire (2 days)
                                     21600      ; minimum (6 hours)
                                     )
                             NS      master.1.1.10.in-addr.arpa.
     $ORIGIN 1.1.10.in-addr.arpa.
     6                       PTR     ftp
                             PTR     www
                             PTR     mail
                             PTR     master
  #vim swht.com.zone
     $ORIGIN .
     $TTL 600        ; 10 minutes
     swht.com                IN SOA  master.swht.com. root.swht.com. (
                                     2014091901 ; serial
                                     3600       ; refresh (1 hour)
                                     300        ; retry (5 minutes)
                                     172800     ; expire (2 days)
                                     21600      ; minimum (6 hours)
                                     )
                             NS      master.swht.com.
                             MX      10 mail.swht.com.
     $ORIGIN swht.com.
     ftp                     CNAME   www
     mail                    A       10.1.1.6
