Question

When my server reboots the ip address for eth0 is 192.168.1.2 when it should be 192.168.1.100 per the static ip address settings in /etc/network/interfaces. After boot if I run service networking restart it will assigning 192.168.1.100 to eth0. Also I don't know if this matters but the hostname displayed in my router is different the the hostname displayed in /etc/hosts.

/etc/network/interfaces

auto lo eth0
iface lo inet loopback

# IPv4 address
auto eth0
iface eth0 inet static
        address 192.168.1.100
        netmask 255.255.255.0
        broadcast 192.168.1.255
        network 192.168.1.0

ip a

ip route show

我不知道16.04，但在以前的版本中，您有网络管理器守护程序设置IP。使用applet＆＃39; nm-applet＆＃39;设置静态地址。右键单击它并转到“编辑连接”。

我解决了部分问题，就像将文件更改为下面的参数大纲一样简单。

的/ etc /网络/接口

# IPv4 address
iface eth0 inet static
   address 192.168.1.100
   netmask 255.255.255.0
   gateway 192.168.1.1
   dns-nameservers 8.8.8.8

现在，当服务器启动时，它将自动分配192.168.1.100，尽管它仍然会分配192.168.1.2。如果我找到一种让它停止分配第二个IP地址的方法，我会更新我的答案。感谢

Ubuntu 16.04 reboots with a different ip address then the static one assigned in /etc/network/interfaces
