网络重启失败（无法启动提升网络接口），网络忽略静态 IP 地址

我有一台运行 ubuntu 的 Linux 服务器。我前段时间设置了这个东西，并设置了一个静态 IP，到目前为止一切都很好。今天，我家突然出现电涌，服务器现在使用了错误的 IP 地址，忽略了 /etc/network/interfaces 文件，我无法重新启动网络。

是否配置

ifconfig
enp3s0: 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::a250:98ca:d9cc:188  prefixlen 64  scopeid 0x20<link>
        ether 30:85:a9:8d:fa:d5  txqueuelen 1000  (Ethernet)

        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 695  bytes 86443 (86.4 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 255  bytes 21586 (21.5 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 255  bytes 21586 (21.5 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

接口文件

 cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto enp3s0
iface enp3s0 inet dhcp

auto lo enp3s0
iface lo inet loopback
iface enp3s0 inet static
        address 192.168.1.7
        netmask 255.255.255.0
        gateway 192.168.1.1
        dns-nameservers 75.75.75.75 75.75.76.76

解析为两个主机名（这对我来说毫无意义）

hostname -I
192.168.1.8 192.168.1.7

网络重启失败

 sudo /etc/init.d/networking restart

我希望服务器使用 192.168.1.7 启动，但我只能通过 192.168.1.8 使用 putty 连接到它。我已经花了两个小时解决这个问题，但一无所获。请帮忙，我很乐意澄清任何问题，也很乐意尝试任何方法。

谢谢！

您已将 enp3s0 设置为使用 dhcp 和静态 IP 地址。

将您的更改/etc/network/interfaces为此...

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

auto enp3s0
iface enp3s0 inet static
        address 192.168.1.7
        netmask 255.255.255.0
        gateway 192.168.1.1
        dns-nameservers 75.75.75.75 75.75.76.76
