bind搭建DNS

systemctl stop firewalld
systemctl disable firewalld
yum install bind*.x86_64 vim -y

systemctl enable named
systemctl start named
yum install -y net-tools
netstat -lntup | grep 53

vim /etc/named.conf
改成listen-on port 53 { any; };
allow-query { any; };
然後在底部添加正向解析
zone “test.com” IN {
type master;
file “test.com.zone”;
};

cd /var/named
cp named.localhost test.com.zone
vim test.com.zone
$TTL 1D
@ IN SOA ns.test.com. root.test.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS ns.test.com.
ns A 10.2.1.64
onlyoffice A 10.2.1.199

檢測配置文件是否報錯
named-checkconf /etc/named.conf
named-checkzone “test.com.” /var/named/test.com.zone

如果沒有報錯重啓named
systemc restart named

測試解析域名:
dig ns.test.com @10.2.1.176

[root@dns named]# dig ns.test.com @10.2.1.176

; <<>> DiG 9.9.4-RedHat-9.9.4-74.el7_6.1 <<>> ns.test.com @10.2.1.176
