1、查看網卡：
root@kali:~# ifconfig
如果ifconfig命令不可用，使用apt-get安裝：
root@kali:~# apt-get -y install net-tools
或者使用ip addr查看：
root@kali:~# ip addr
2、修改network配置文件
文件位置：
/etc/network/interfaces
原始文件內容（修改前）：
root@kali:~# cat /etc/network/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
修改后文件內容：
# 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
auto eth0
iface eth0 inet static
address 192.168.0.66
netmask 255.255.255.0
gateway 192.168.0.1
主要是在文件末尾增加以下內容：
auto eth0 //指定網卡（根據ifconfig結果修改）
iface eth0 inet static //啟動靜態ip
address 192.168.0.66 // 設置靜態ip
netmask 255.255.255.0 //子網掩碼
gateway 192.168.0.1 //指定網關
3、重啟網絡：
service networking restart
或者：
systemctl restart networking
# start、status、stop、restart分別表示：啟動、查看狀態、停止、重啟
查看networking狀態：
root@kali:~# systemctl status networking
● networking.service - Raise network interfaces
Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor preset: enabled)
Active: active (exited) since Mon 2020-07-20 13:06:57 CST; 22s ago
# 看到active (exited)表示正常啟動了
4、查看ip
可以看到ip變成了我們設置的ip
root@kali:~# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.0.66 netmask 255.255.255.0 broadcast 192.168.0.1
