## 主机名 hadoop4 IP 192.168.0.106 作为DNS服务器
## 安装bind相应的软件包：
[root@hadoop4 ~]# yum -y install bind bind-utils bind-chroot
## 检查是否安装bind:
[root@hadoop4 ~]# rpm -qa | grep '^bind'
bind-chroot-9.8.2-0.30.rc1.el6_6.2.x86_64
bind-9.8.2-0.30.rc1.el6_6.2.x86_64
bind-libs-9.8.2-0.30.rc1.el6_6.2.x86_64
bind-utils-9.8.2-0.30.rc1.el6_6.2.x86_64
## 修改/etc/named.conf
[root@hadoop4 ~]# vim /etc/named.conf
listen-on port 53 { any; }; //将原来的127.0.0.1改成any
allow-query { any; }; //将原来的localhost改成any
## 修改/etc/named.rfc1912.zones，将两个zone增加在/etc/named.rfc1912.zones 文件最后（也可以直接写在named.conf中）
[root@hadoop4 ~]# vim /etc/named.rfc1912.zones
zone "hadoop.com" IN {
type master;
file "named.hadoop.com";
allow-update { none; };
};
zone "0.168.192.in-addr.arpa" IN {
type master;
file "named.192.168.0.zone";
allow-update { none; };
};
## 配置正向解析文件
[root@hadoop4 ~]# cd /var/named
[root@hadoop4 named]# cp -p named.localhost named.hadoop.com
[root@hadoop4 named]# vim named.hadoop.com
$TTL 1D
@ IN SOA hadoop4.hadoop.com. grid.hadoop4.hadoop.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
@ IN NS hadoop4.hadoop.com.
hadoop4.hadoop.com. IN A 192.168.0.106
hadoop5.hadoop.com. IN A 192.168.0.107
hadoop6.hadoop.com. IN A 192.168.0.108
## 配置反向解析文件
[root@hadoop4 ~]# cd /var/named
[root@hadoop4 named]# cp -p named.localhost named.192.168.0.zone
[root@hadoop4 named]# vim named.192.168.0.zone
$TTL 1D
@ IN SOA hadoop4.hadoop.com. grid.hadoop4.hadoop.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
@ IN NS hadoop4.hadoop.com.
106 IN PTR hadoop4.hadoop.com.
107 IN PTR hadoop5.hadoop.com.
108 IN PTR hadoop6.hadoop.com.
## 添加DNS域名服务器ip，在每个节点的 /etc/sysconfig/network-scripts/ifcfg-eth0 文件中加入服务器ip地址
[root@hadoop4 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=08:00:27:26:b8:c1
TYPE=Ethernet
UUID=dabd3173-5f69-454c-aa97-5cc2a09dfba0
ONBOOT=yes
NM_CONTROLLED=yes
#BOOTPROTO=dhcp
BOOTPROTO=static
BROADCAST=192.168.0.255
IPADDR=192.168.0.106
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
DNS1=192.168.0.106
[root@hadoop4 ~]# service network restart
## 启动DNS
[root@hadoop4 ~]# service named start
启动 named： [确定]
## 设置开机启动
[root@hadoop4 ~]# chkconfig named on
## 查看日志确认DNS服务是否正常
[root@hadoop4 ~]# tail -n 30 /var/log/messages | grep named

## 验证测试
[root@hadoop4 ~]# nslookup hadoop4.hadoop.com
Server: 192.168.0.106
Address: 192.168.0.106#53
Name: hadoop4.hadoop.com
Address: 192.168.0.106
[root@hadoop4 ~]# nslookup 192.168.0.107
Server: 192.168.0.106
Address: 192.168.0.106#53
107.0.168.192.in-addr.arpa name = hadoop5.hadoop.com.
由于我在自己的实验环境里节点都只设置了主机名(hostname)，而没有设置域名(domainname)，所以我更改了一些设置，来达到仅仅解析hostname的目的
[root@hadoop4 ~]# cat /etc/named.rfc1912.zones
zone "." IN {
type master;

allow-update { none; };
};

allow-update { none; };
};
