DNS服务器布署
DNS服务器布署
1.搭建dns服务器能够对自定义的正向或者反向域完成数据解析查询。
2.配置从DNS服务器，对主dns服务器进行数据备份。
正反向解析
[root@localhost redhat]# vim /etc/named.conf
options {
listen-on port 53 { 192.168.79.128; };
directory "/var/named";
allow-query { any;};
zone "openlab.com" IN {
type master;
file "named.openlab.com";
};
zone "79.168.192.in-addr.arpa" IN {
type master;
file "named.192";
allow-update { none; };
};
[root@localhost redhat ]# vim /var/named/named.openlab.com ------正向资源记录文件

NS ns.openlab.com.
128 PTR ns.openlab.com
130 PTR www.openlab.com
131 PTR ftp.openlab.com
关闭防火墙
[root@localhost redhat]# systemctl stop firewalld
[root@localhost redhat]# setenforce 0
[root@localhost redhat]# systemctl restart named
主从服务器
完全区域传送
主服务器配置：添加 allow-transfer { 192.168.111.128; };，其他不变。

关闭防火墙
[root@localhost redhat]# systemctl stop firewalld
[root@localhost redhat]# setenforce 0
[root@localhost redhat]# systemctl restart named
从服务器
[root@localhost redhat]# mount /dev/sr0 /mnt
mount: /mnt: /dev/sr0 already mounted on /mnt.
[root@localhost redhat]# systemctl disable firewalld
[root@localhost redhat]# setenforce 0
[root@localhost redhat]# dnf install bind
[root@localhost redhat]# vim /etc/named.conf
[root@localhost redhat]# cat /etc/named.conf
options {
listen-on port 53 { 192.168.79.128; };
directory "/var/named/slaves"; ------可以修改为/var/named/slaves
allow-query { any;};
};
zone "openlab.com" IN {
type slave; ----------------------------修改
file "named.openlab.com";
masters { 192.168.79.130; }; ----------------添加
};
zone "79.168.192.in-addr.arpa" IN {
type slave; ---------------------------修改
file "named.192";
masters { 192.168.79.130; }; ----------------添加
};
测试，重启从服务器主机后，在/var/named/slaves目录下可以看到正反向的资源记录文件
[root@localhost redhat]# ls -l /var/named/slaves/ -----此时从服务器下没有文件
total 0
[root@localhost redhat]# systemctl restart named -----从服务器重启后，在这个目录下可以看到正反向的资源记录文件
[root@localhost redhat]# ls -l /var/named/slaves/
total 8

-rw-r--r--. 1 named named 396 Nov 2 05:26 named.openlab.com
