为什么在 Debian 上重启网络不起作用？

Question

为什么重新启动网络无法在我的服务器上成功重新启动 eth0？我的 CentOS 虚拟机都没有这个问题。

root@machine:~# 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).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
 address 192.168.1.110
 gateway 192.168.1.1
 netmask 255.255.255.0
 network 192.168.1.0
 broadcast 192.168.1.255

解决方案是通过自动替换allow-hotplug。谢谢！:)
