RHEL5.4下使用bind配置DNS服务器(3)

vi benet.fx
$TTL    86400
@       IN      SOA     linuxidc.com. root.linuxidc.com. (
                                      1997022700 ; Serial
                                      28800      ; Refresh
                                      14400      ; Retry
                                      3600000    ; Expire
                                      86400 )    ; Minimum
        IN      NS      ns1.linuxidc.com.
102     IN      PTR     ns1.linuxidc.com.
102     IN      PTR    
102     IN      PTR     server01.linuxidc.com.
105     IN      PTR     mail.linuxidc.com.
103     IN      PTR     ns2.linuxidc.com.

(4) 重新启动named服务
service named restart
(5) 配置客户端测试
nslookup

################################分割线 构建从域名服务器###########################
(1) 假设从域名服务器的IP地址为192.168.1.103
主机名为：ns2.linuxidc.com
(2) 在从域名服务器上创建主配置文件
vi /var/named/chroot/etc/named.conf
options
{
        listen-on port 53 { 192.168.1.103; };
        directory "/var/named";
        dump-file               "/var/named/data/cache_dump.db";
        statistics-file         "/var/named/data/named_stats.txt";
        memstatistics-file      "/var/named/data/named_mem_stats.txt";
        allow-query { 192.168.1.0/24; };
        recursion yes;
};
zone "linuxidc.com" IN {
        type slave;
masters { 192.168.1.102; };
        file "benet.zx";
};
zone "1.168.192.in-addr.arpa" IN {
        type slave;
masters { 192.168.1.102; };
        file "benet.fx";
};
(3) 在主域名服务器上修改主配置文件为：
vi /var/named/chroot/etc/named.conf
options
{
        listen-on port 53 { 192.168.1.102; };
        directory "/var/named";
        dump-file               "/var/named/data/cache_dump.db";
        statistics-file         "/var/named/data/named_stats.txt";
        memstatistics-file      "/var/named/data/named_mem_stats.txt";
        allow-query { 192.168.1.0/24; };
        recursion yes;
};
zone "linuxidc.com" IN {
        type master;
        file "benet.zx";
allow-transfer { 192.168.1.103; };
};
zone "1.168.192.in-addr.arpa" IN {
        type master;
        file "benet.fx";
allow-transfer { 192.168.1.103; };
};
(4) 在从域名服务器上启动named服务或重启
server named start
(5) 可以查看日志
tail /var/log/messages
(6) 重新配置客户端测试从域名服务器
