hostname:顯示hostname
hostname -h:求救
hostname -b google:將hostname更改為google

apt install bind9:安裝DNS Server
apt install dnsutils:DNS測試工具(應包含在bind9了)

ufw status:查看ubuntu防火牆狀態

NameCheap設定

申請google.me網域
在側邊欄點DashBoard -> MANAGE
NAMESERVERS -> Custom DNS -> 輸入兩個DNS Server(ns1.google.me./ns2.google.me)
Advanced DNS -> PERSONAL DNS SERVER 綁定IP

$TTL    604800

                              2         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL

@       IN      NS      ns2.google.me.
ns2     IN      A       xxx.xxx.xxx.xxx
;
www     IN      A       yyy.yyy.yyy.yyy
@       IN      A       yyy.yyy.yyy.yyy

google.me的NS是ns2.google.me
ns2.google.me指向的IP為自己
www.google.me=yyy.yyy.yyy.yyy
google.me=yyy.yyy.yyy.yyy

開啟

systemctl start bind9.service
systemctl restart bind9.service
systemctl status bind9.service
