RHEL5——從DNS服務器的搭建
本文接上一篇主DNS服務器的搭建 http://ssxiaoguai.blog.51cto.com/5376644/1436057
1）設置IP地址
[root@DNS_2~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 #Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) DEVICE=eth0 BOOTPROTO=none HWADDR=00:0C:29:22:36:43 ONBOOT=yes IPADDR=192.168.1.253 NETMASK=255.255.255.0
2）安裝軟件包
[root@DNS_2 ~]# yum -y install bindbind-chroot caching-nameserver
3）修改從DNS的配置文件
[root@DNS_2 ~]# cd /var/named/chroot/etc/
localtime named.caching-nameserver.conf named.rfc1912.zones rndc.key
[root@DNS_2 etc]# cp -pnamed.caching-nameserver.conf named.conf
[root@DNS_2 etc]# vim named.conf
options {
listen-on port 53{ any; };
// listen-on-v6 port53 { ::1; };
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";
// Those optionsshould be used carefully because they disable port
// randomization
//query-source port 53;
// query-source-v6port 53;
allow-query { any; };
allow-query-cache{ any; };
};
logging {
channeldefault_debug {
file"data/named.run";
severity dynamic;
};
};
view localhost_resolver {
match-clients { any; };
match-destinations{ any; };
recursion yes;
include"/etc/named.rfc1912.zones";
};
[root@DNS_2etc]# vim named.rfc1912.zones
zone "ssxiaoguai.com" IN {
type slave;
file"slave/ssxiaoguai.zone";
masters{192.168.1.254;};
};
zone "1.168.192.in-addr.arpa" IN {
type slave;
file"slaves/ssxiaoguai.arpa";
masters{192.168.1.254;};
};4）檢測配置文件語法
[root@DNS_2 etc]# named-checkconfnamed.conf [root@DNS_2 etc]# named-checkconfnamed.rfc1912.zones
5）修改主DNS配置文件
[root@DNS_1 ~]# vim/var/named/chroot/etc/named.conf
allow-transfer { 192.168.10.101; };6）分別重啓主從服務器的服務。
[root@DNS_1 ~]# service named restart 停止 named：. [確定] 啓動 named： [確定] [root@DNS_2 etc]# service named restart 停止 named： [確定] 啓動 named： [確定] [root@DNS_2 etc]# chkconfig named on
7）測試
成功同步主服務器數據庫文件，並能夠正常解析。
