本文形容下debian11的初始化工作。
首先，咱们应用普通用户登录到debian，而后应用su -命令来切到root用户。留神： 肯定要是su -，而不是su
$ su -设置IP地址
应用root登录后，批改/etc/network/interfaces文件：
# The primary network interface# 正文掉这行，并记录这个相似于 ens192 的关键字# allow-hotplug ens192 # 正文点这行同时#iface ens192 inet dhcp# 退出以下行，留神ens192是咱们从下面复制下来的，不同的电脑不一样auto ens192iface ens192 inet static# 以下请依据本人的理论状况设置address 192.168.1.17netmask 255.255.255.0gateway 192.168.1.1dns-nameservers 192.168.1.1编辑后退出，而后执行：systemctl restart networking.service使配置失效.
装置sudo
默认debian11并没有装置sudo，装置过程如下：
更新源
如果操作系统是以CD形式装置的，那么CD会默认成为软件源（这在离线的网络环境中是必要的），而以后咱们的服务器有网络环境，同时装置完操作系统后，CD曾经弹出，所以此时须要勾销掉软件源：
$ nano /etc/apt/sources.list
# 正文掉以cd rom开始的源# deb cdrom:[Debian GNU/Linux 11.4.0 _Bullseye_ - Official amd64 DVD Binary-1 2># deb cdrom:[Debian GNU/Linux 11.4.0 _Bullseye_ - Official amd64 DVD Binary-1 2>而后增加一些国内的官网源的中的华为镜像，最终文件如下：
# deb cdrom:[Debian GNU/Linux 11.4.0 _Bullseye_ - Official amd64 DVD Binary-1 20220709-10:33]/ bullseye contrib main# deb cdrom:[Debian GNU/Linux 11.4.0 _Bullseye_ - Official amd64 DVD Binary-1 20220709-10:33]/ bullseye contrib main# huaweideb https://mirrors.huaweicloud.com/debian/ bullseye main contrib non-freedeb-src https://mirrors.huaweicloud.com/debian/ bullseye main contrib non-freedeb https://mirrors.huaweicloud.com/debian/ bullseye-updates main contrib non-freedeb-src https://mirrors.huaweicloud.com/debian/ bullseye-updates main contrib non-freedeb https://mirrors.huaweicloud.com/debian/ bullseye-backports main contrib non-freedeb-src https://mirrors.huaweicloud.com/debian/ bullseye-backports main contrib non-freedeb https://mirrors.huaweicloud.com/debian-security bullseye-security main contrib non-freedeb-src https://mirrors.huaweicloud.com/debian-security bullseye-security main contrib non-free#deb http://security.debian.org/debian-security bullseye-security main contrib#deb-src http://security.debian.org/debian-security bullseye-security main contrib# bullseye-updates, to get updates before a point release is made;# see https://www.debian.org/doc/manuals/debian-reference/ch02.en.html#_updates_and_backports# A network mirror was not selected during install.

更新源
$ apt update装置sudo
debian11默认未装置sodu,执行：apt install sudo进行装置.
退出sudoers
$ usermod -aG sudo yourusername而后，咱们登记以后的shell，再从新登录一个。此时，便能够应用sudo命令了。
