设置静态IP

root@xueji:~# vim /etc/network/interfaces
# interfaces() file used by ifup() and ifdown()
auto lo
iface lo inet loopback    #这行下面添加
auto ens33
iface ens33 inet static
address 192.168.244.10
netmask 255.255.255.0
gateway 192.168.244.2

DNS的设置及查看

root@xueji:~# vim /etc/systemd/resolved.conf
[Resolve]
DNS=119.29.29.29 223.5.5.5   #多个DNS地址使用空格分隔
#FallbackDNS=
#Domains=
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
#DNSOverTLS=no
#Cache=yes
#DNSStubListener=yes
