本篇内容主要讲解“Centos7怎么搭建主从DNS服务器”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“Centos7怎么搭建主从DNS服务器”吧!
1、准备
例：两台192.168.11.10(主),192.168.11.11(从),域名
# 主从dns服务器均需要安装bind、bind-chroot、bind-utils yum -y install bind bind-utils bind-chroot # 如果防火墙开启，配置防火墙，添加服务(防火墙已禁用则忽略) firewall-cmd --permanent --add-service=dns firewall-cmd --reload
2、主dns服务器(192.168.11.10)配置
# 编辑配置文件 vim /etc/named.conf # 找到其中两行 listen-on port 53 { 127.0.0.1; }; allow-query { localhost; }; # 修改为 listen-on port 53 { any; }; allow-query { any; };3、配置正向解析
# 编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域 zone "test1.com" in { type master; file "data/test1.com.zone"; }; # 创建test1.com.zone解析域 vim /var/named/data/test1.com.zone $ttl 3h @ in soa test1.com. root ( 20180928 ; serial 1d ; refresh 1h ; retry 1w ; expire 3h ) ; minimum in ns @ in a 192.168.11.10 www in a 192.168.11.10 ftp in a 192.168.11.10 # 编辑/etc/resolv.conf，添加 search localdomain nameserver 192.168.11.104、重启dns服务器
# 重启named systemctl restart named # 查看状态 systemctl status named
5、检查解析是否成功
# ping命令验证 ping -c 4 www.test1.com # 输出如下即解析成功 ping www.test1.com (192.168.11.10) 56(84) bytes of data. 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=1 ttl=64 time=0.033 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=3 ttl=64 time=0.066 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=4 ttl=64 time=0.057 ms --- www.test1.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.033/0.053/0.066/0.014 ms # nslookup命令验证 nslookup >www.test1.com # 输出如下即解析成功 server: 192.168.11.10 address: 192.168.11.10#53 name: www.test1.com address: 192.168.11.10
6、配置反向解析
# 编辑文件/etc/named.rfc1912.zones，在末尾添加 vim etc/named.rfc1912.zones zone "11.168.192.in-addr.arpa" in { type master; file "data/11.168.192.zone"; }; # 创建11.168.192.zone解析域 vim /var/named/data/11.168.192.zone $ttl 3h @ in soa web3.com. root ( 20180928; serial 1d ; refresh 1h ; retry 1w ; expire 3h ) ; minimum @ in ns www.test1.com. 10 in ptr www.test1.com. 10 in ptr ftp.test1.com.7、重启dns服务器
# 重启named systemctl restart named # 查看状态 systemctl status named
8、检查解析是否成功
# ping命令验证 ping -c 4 192.168.11.10 # 输出如下即解析成功 ping 192.168.11.10 (192.168.11.10) 56(84) bytes of data. 64 bytes from 192.168.11.10: icmp_seq=1 ttl=64 time=0.061 ms 64 bytes from 192.168.11.10: icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from 192.168.11.10: icmp_seq=3 ttl=64 time=0.081 ms 64 bytes from 192.168.11.10: icmp_seq=4 ttl=64 time=0.060 ms --- 192.168.11.10 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.058/0.065/0.081/0.009 ms # nslookup命令验证 nslookup 192.168.11.10 # 输出如下即解析成功 server: 192.168.11.10 address: 192.168.11.10#53 10.11.168.192.in-addr.arpa name = ftp.test1.com. 10.11.168.192.in-addr.arpa name = www.test1.com.
9、配置从dns服务器(192.168.11.11)
# 先修改主dns服务器(192.168.11.10)的配置/etc/named.rfc1912.zones vim /etc/named.rfc1912.zones zone "test1.com" in { type master; file "data/test1.com.zone"; allow-transfer {192.168.11.11;}; notify yes; also-notify {192.168.11.11;}; }; zone "11.168.192.in-addr.arpa" in { type master; file "data/11.168.192.zone"; allow-transfer {192.168.11.11;}; notify yes; also-notify {192.168.11.11;}; };10、配置从dns服务器(192.168.11.11)正向解析
# 编辑named.conf文件 vim /etc/named.conf # 找到其中两行 listen-on port 53 { 127.0.0.1; }; allow-query { localhost; }; # 修改为 listen-on port 53 { any; }; allow-query { any; }; # 编辑文件/etc/named.rfc1912.zones，在末尾添加需要解析的域 vim /etc/named.rfc1912.zones zone "test1.com" in { type slave; file "data/test1.com.zone"; }; masters { 192.168.11.10; }; # 创建test1.com.zonek空文件 touch /var/named/data/test1.com.zone # 设置所有者 chown named:named test1.com.zone # 编辑/etc/resolv.conf，添加 vim /etc/resolv.conf search localdomain nameserver 192.168.11.1111、重启dns服务器
# 重启named systemctl restart named # 查看状态 systemctl status named
12、检测解析是否成功
# ping命令验证 ping -c 4 www.test1.com # 输出如下即解析成功 ping www.test1.com (192.168.11.10) 56(84) bytes of data. 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=1 ttl=64 time=0.033 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=3 ttl=64 time=0.066 ms 64 bytes from ftp.test1.com (192.168.11.10): icmp_seq=4 ttl=64 time=0.057 ms --- www.test1.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.033/0.053/0.066/0.014 ms # nslookup命令验证 nslookup >www.test1.com # 输出如下即解析成功 server: 192.168.11.11 address: 192.168.11.11#53 name: www.test1.com address: 192.168.11.10
13、配置从dns服务器(192.168.11.11)反向解析
# 在文件/etc/named.rfc1912.zones中添加 vim etc/named.rfc1912.zones zone "11.168.192.in-addr.arpa" in { type master; file "data/11.168.192.zone"; masters { 192.168.11.10; }; }; # 创建空文件11.168.192.zone touch /var/named/data/11.168.192.zone # 设置所有者 chown named:named 11.168.192.zone14、重启dns服务器
# 重启named systemctl restart named # 查看状态 systemctl status named
15、查看文件/var/named/data/test1.com.zone和/var/named/data/11.168.192.zone是否有二进制数据
cat /var/named/data/test1.com.zone cat /var/named/data/11.168.192.zone
16、检查解析是否成功
# ping命令验证 ping -c 4 192.168.11.11 # 输出如下即解析成功 ping 192.168.11.11 (192.168.11.11) 56(84) bytes of data. 64 bytes from 192.168.11.11: icmp_seq=1 ttl=64 time=0.061 ms 64 bytes from 192.168.11.11: icmp_seq=2 ttl=64 time=0.058 ms 64 bytes from 192.168.11.11: icmp_seq=3 ttl=64 time=0.081 ms 64 bytes from 192.168.11.11: icmp_seq=4 ttl=64 time=0.060 ms --- 192.168.11.11 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.058/0.065/0.081/0.009 ms # nslookup命令验证 nslookup 192.168.11.11 # 输出如下即解析成功 server: 192.168.11.11 address: 192.168.11.11#53 10.11.168.192.in-addr.arpa name = ftp.test1.com. 10.11.168.192.in-addr.arpa name = www.test1.com.
