网络服务无法启动/无法在重新启动时启动。
Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code.
我仍然可以通过远程控制台访问服务器,但是别无选择,因为没有网络,就没有出路也没有出路。
systemctl statusnetworking.service说:

我的/ etc / network / interfaces看起来像:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp
我在哪里可以开始调试?
感谢您的提示!问候,K
# sudo ifup --verbose eth0

Usage: dhclient <snip>
Failed to bring up eth0.
sudo ifup --verbose eth0
来看看哪里出了问题吗?
/var/log/syslog
。您可以尝试dhclient
自行手动执行命令。如果没有错误消息出现,则说明没有问题dhclient
。
up
通过一一执行位于中的脚本来引入网络接口/etc/network/if-up.d
。其中之一包含dhclient
失败的命令。所以做类似的事情grep -R dhclient /etc/network/if-up.d/*
,看看你得到什么。
