修改源，禁用DVD，并设置为网易源

cat > /etc/apt/sources.list << EOF

配置DNS：（此方法重启失效）

root@localhost:/# cat /etc/resolv.conf

#This file is managed by man:systemd-resolved(8). Do not edit.
#See man:systemd-resolved.service(8) for details about the supported modes of
#operation for /etc/resolv.conf. 
nameserver 192.168.0.1
options edns0 trust-ad

配置DNS 长期有效,resolv.conf 现在归systemd管，需要修改/etc/systemd/resolved.conf 文件

root@localhost:/# cat /etc/systemd/resolved.conf 
#This file is part of systemd.
#See resolved.conf(5) for details
[Resolve]
DNS=192.168.0.1
#FallbackDNS=
#Domains=
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
#DNSOverTLS=no
#Cache=no-negative
#DNSStubListener=yes
#ReadEtcHosts=yes

然后重启服务

systemctl restart systemd-resolved.service

查看结果
