我一直在开发一个App要求，要求更改IP方案并重新启动网络服务，以便永久保存更改的IP地址。
每次尝试后，我都会重新启动网络服务并且工作正常，但出于某种原因，它现在正在抛出以下错误。
# /etc/init.d/networking restart
* Running /etc/init.d/networking restart is deprecated because
it may not enable again some interfaces
* Reconfiguring network interfaces... RTNETLINK answers: File exists
Failed to bring up eth0.
也试过
# service networking restart
stop: Unknown instance:
networking stop/waiting

# sudo ifdown eth0 && sudo ifup eth0
ifdown: interface eth0 not configured
