Hello World

如果裝好的 Debian 11 的ip 想由 dhcp 改成靜態ip
首先先看目前網卡的代號
root@debian-lab:/etc# ip address

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:c5:c7:e0 brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.111/24 brd 10.0.2.255 scope global enp0s3
       valid_lft forever preferred_lft forever
    inet6 fe80::a00:27ff:fec5:c7e0/64 scope link
       valid_lft forever preferred_lft forever

上面的結果可以知道我們的網卡代號是 enp0s3

進到 /etc/network 目錄
root@debian-lab:/etc# cd /etc/network/

檢查主要的設定檔
root@debian-lab:/etc/network# cat interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

在 /etc/network/interfaces.d/ 新增 enp0s3 網卡的設定檔
root@debian-lab:/etc/network# cd interfaces.d/
root@debian-lab:/etc/network/interfaces.d# vi enp0s3
auto enp0s3
iface enp0s3 inet static
 address 10.0.2.11
 netmask 255.255.255.0
 gateway 10.0.2.2
 

重開機試試
