在具有3个networking接口（1个DHCP和2个静态IP）的云服务器上执行Debian Stretch的新安装之后，我决定不需要可预测的networking接口。 我禁用他们添加net.ifnames=0 Grub内核启动线。
这样做后，networking接口eth1和eth2（2个静态的）将不起作用：
$ifup eth1 RTNETLINK answers: File exists ifup: failed to bring up eth1
/ etc / network / interfaces的内容：
# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet dhcp # web1.domain.com auto eth1 iface eth1 inet static address 100.100.100.227 netmask 255.255.255.0 network 100.100.100.0 gateway 100.100.100.1 broadcast 100.100.100.255 # web2.domain.com auto eth2 iface eth2 inet static address 100.100.100.177 netmask 255.255.255.0 network 100.100.100.0 gateway 100.100.100.1 broadcast 100.100.100.255
任何想法可能导致这一点？ 在以前的Debian版本中，我已经成功地使用了这个configuration。
ip a输出：
