网卡配置

1. 修改/etc/network/interfaces

address 192.168.0.188 
gateway 192.168.0.1 
netmask 255.255.255.0

2. 重启网卡systemctl restart networking.service
   systemctl restart networking

执行apt 报错

root@debian:~# apt update
忽略:1 cdrom://[Debian GNU/Linux 11.7.0 _Bullseye_ - Official amd64 DVD Binary-1 20230429-11:50] bullseye InRelease
错误:2 cdrom://[Debian GNU/Linux 11.7.0 _Bullseye_ - Official amd64 DVD Binary-1 20230429-11:50] bullseye Release
  请使用 apt-cdrom，通过它可以让 APT 识别该盘片。apt-get upgdate 不能被用来加入新的盘片。

E: 仓库 “cdrom://[Debian GNU/Linux 11.7.0 _Bullseye_ - Official amd64 DVD Binary-1 20230429-11:50] bullseye Release” 没有 Release 文件。
N: 无法安全地用该源进行更新，所以默认禁用该源。
N: 参见 apt-secure(8) 手册以了解仓库创建和用户配置方面的细节。

修改源，禁用DVD，并设置为网易源

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
