Ubuntu 16.04 LTS与虚拟接口
提问于 2019-06-05 10:34:27
嗨，尝试了不同的谷歌搜索建议。
至于今天，我有：
描述:Ubuntu16.04.6 LTS发行版: 16.04代码: xenial
更新为昨天
试图使：
sudo ip address add 192.168.0.7/24 dev enz3 ;
sudo ip address add 192.168.0.8/24 dev enz3永久的
我将etc/network/interfaces文件修改为：
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
iface enz3 inet static
address 192.168.0.2
netmask 255.255.255.0
gateway 192.168.0.1
auto enz3:1
allow-hotplug enz3:1
iface enz3:1 inet static
address 192.168.0.7
netmask 255.255.255.0
gateway 192.168.0.1
auto enz3:2
allow-hotplug enz3:2
iface enz3:2 inet static
address 192.168.0.8
netmask 255.255.255.0
gateway 192.168.0.1然后重新启动网络服务。
systemctl restart networking我收到一个错误：
xx@xx-VBox:~$ systemctl status networking.service

来自于192.168.0.2地址的默认for服务器
对于两个虚拟主机，分别为192.168.0.7和192.168.0.8
我错过了什么？我为什么要犯这个错误？其他的东西不适用于这个设置吗？
编辑
该系统只用于访问apache2 can服务器:从外部可以访问: 192.168.0.02 192.168.0.07 192.168.0.08
从内部(192.168.0.2)我可以访问: localhost 192.168.0.7 192.168.0.8
但我不能从外面(192.168.0.3)或从里面上网( 192.168.0.2 )。我可以在VM内部打开主机192.168.0.3 (192.168.0.2是VirtualBox上的VM )
从VM内部查找剂量工作(192.168.0.2)

iproute2 method
Also, ifupdown supports specifying multiple interfaces by repeating iface sections with the same interface name. The key difference from the method described above is that all such sections are treated by ifupdown as just one interface, so user can't add or remove them individually. However, up/down commands, as well as scripts, are called for every section as it used to be.
Note however that this method is dangerous! Certain driver/hardware combinations may sometimes fail to bring the link up if no labels are assigned to the alias interfaces. (Seen this on Debian Wheezy and Jessie with RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 01) auto-negotiating to 10/full. A similar warning from another person exists in the history of this page.)
This /etc/network/interfaces text assigns three IP addresses to eth0.
auto eth0
allow-hotplug eth0
iface eth0 inet static
address 192.168.1.42/24
gateway 192.168.1.1
iface eth0 inet static
address 192.168.1.43/24
iface eth0 inet static
address 192.168.1.44/24
# adding IP addresses from different subnets is also possible
iface eth0 inet static
address 10.10.10.14/24但即使使用标签(或者至少我认为我在使用它们)：
auto enz3
allow-hotplug enz3
iface enz3 inet static
address 192.168.0.2
netmask 255.255.255.0
gateway 192.168.0.1
iface enz3:1 inet static
address 192.168.0.7
netmask 255.255.255.0
iface enz3:2 inet static
address 192.168.0.8
netmask 255.255.255.0我仍然会发现错误：
giu 05 17:38:43 dv-VBox systemd[1]: Stopped Raise network interfaces.
