dns服务部署

配置主文件，编辑主配置文件设置监听IP

，

重启服务：[root@localhost ~]# systemctl restart network

安装bind

主服务器IP信息：
[root@localhost ~]# nmcli c modify ens160 ipv4.method manual ipv4.addresses '129.168.160.131/24' ipv4.gateway’192.168.160.2‘ ipv4.dns '192.168.160.131'
[root@localhost ~]# nmcli c reload
[root@localhost ~]# nmcli c up ens160 从服务器IP信息：
[root@node ~]# nmcli c modify en160 ipv4.method manual ipv4.addresses '192.168.160.132/24' ipv4.gateway '192.168.160.2' ipv4.dns '192.168.160.132'
[root@node ~]# nmcli  c  reload
[root@node ~]# nmcli  c  up  ens160

正向解析：
[root@localhost ~]# cd /var/named
[root@localhost named]# ls
data     named.ca     named.localhost  named.openlab.com
dynamic  named.empty  named.loopback   slaves
[root@localhost named]# cp -a named.localhost openlab.com.zone
反向解析：
[root@localhost named]# ls
data     named.ca     named.localhost  named.openlab.com  slaves
dynamic  named.empty  named.loopback   openlab.com.zone
[root@localhost named]# cp -a named.loopback 192.18.160.arpa

新建正向区域配置文件：[root@localhost ~]# vim /var/named/named.openlab.com

反向解析配置文件：

主服务端重启服务：#systemctl restart named

从服务端配置主文件：
[root@node ~]# cat /etc/named.conf11    listen-on port 53 { 192.168.48.132; }; 
19    allow-query    { any; }; [root@node ~]# cat /etc/named.rfc1912.zoneszone "openlab.com" IN {type slave;masters { 192.168.160.132; };file "slaves/openlab.com.zone";
};
zone "160.168.192.in-addr.arpa" IN {type slave;masters { 192.168.160.132; };file "slaves/192.168.160.arpa";
};

从服务端操作，确认从服务端的网卡DNS地址修改为自己的IP：192.168.160.132[root@node ~]# nslookup  www.openlab.com
[root@node ~]# nslookup  192.168.160.131
[root@node ~]# dig @192.168.160.131 www.openlab.com
