设置静态 IP 地址的 etc/network/interfaces 应该是什么？

我尝试设置静态 IP 地址（192.168.2.1）

这里的输出ifconfig

我使用 wifi 适配器连接：

wlx4c0fc7f11daf: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.8  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::8955:c94:4868:c112  prefixlen 64  scopeid 0x20<link>

我的问题是：我应该在“etc/network/interfaces”中添加什么？

实际内容是：

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

答案1

附加以下内容为/etc/network/interfacesenp3s0 设备分配静态地址：

auto enp3s0
iface enp3s0 inet static
    address 192.168.2.1
    netmask 255.255.255.0
    network 192.168.2.0
    broadcast 192.168.2.255
    gateway <your-router-ip-address-goes-here>
    dns-nameservers 1.1.1.1 8.8.8.8
