Centos7搭建主从DNS服务器的教程

时间:2021-05-19

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-utilsyum -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=dnsfirewall-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 192.168.11.10

4、重启DNS服务器

# 重启namedsystemctl 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 # 输出如下即解析成功  PING (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  --- 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># 输出如下即解析成功  Server: 192.168.11.10  Address: 192.168.11.10#53  Name:   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 .  10 IN PTR .  10 IN PTR ftp.test1.com.

7、重启DNS服务器

# 重启namedsystemctl 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 = .

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.zonesvim /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 192.168.11.11

11、重启DNS服务器

# 重启namedsystemctl 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 # 输出如下即解析成功  PING (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  --- 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># 输出如下即解析成功  Server: 192.168.11.11  Address: 192.168.11.11#53  Name:   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.zonetouch /var/named/data/11.168.192.zone# 设置所有者  chown named:named 11.168.192.zone

14、重启DNS服务器

# 重启namedsystemctl 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.zonecat /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 = .
