我有一台 ubuntu 14.10 服务器，启动时需要很长时间，当它启动时，它没有网络（这导致启动时有很长时间的延迟） dmesg | tail。
[ 225.013622] init: networking pre-start process (1401) terminated with status 1
[ 225.015451] init: networking post-stop process (1405) terminated with status 100
[ 228.512454] init: networking pre-start process (1415) terminated with status 1
[ 228.514132] init: networking post-stop process (1419) terminated with status 100
谷歌了一下，这个问题似乎与文件 /etc/network/interfaces 有关，以下是该文件的内容：（em1 是唯一以太网接口的名称）
# 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
auto em1
iface em1 inet DHCP
# This is an autoconfigured IPv6 interface
我必须连接显示器和键盘，然后打字ifconfig em1; dhclient em1才能工作。这很不方便。有什么想法吗？谢谢。
答案1
我认为你应该用“dhcp”替换“DHCP”：
# 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
auto em1
iface em1 inet dhcp
# This is an autoconfigured IPv6 interface
并重启网络：
sudo /etc/init.d/networking restart
