多个 IP - 不同的网关 - 一个接口 - Debian Squeezy

我在这里和其他地方读了很多答案，但找不到合适的答案。我尝试了几种解决方案，但都不起作用。我有一台只有一个接口 eth0 的服务器。我有多个 IP，但我无法让它们工作。也许你可以帮助我。

etc/network/interfaces（我在网上找到了这个解决方案，和许多其他解决方案一样）：

    # 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 eth0
iface lo inet loopback

# The primary network interface
auto eth0
allow-hotplug eth0
iface eth0 inet static
    address 31.133.CCC.47
    netmask 255.255.255.0
    broadcast 31.133.CCC.255
    network 31.133.CCC.0
  post-up route add default gw 31.133.CCC.1 metric 1
  pre-down route del default gw 31.133.CCC.1

auto eth0:0
allow-hotplug eth0
iface eth0 inet static
    address 31.133.XXX.254
    netmask 255.255.255.128
  post-up route add default gw 31.133.XXX.129 metric 2
  pre-down route del default gw 31.133.XXX.129

auto eth0:1
allow-hotplug eth0
iface eth0 inet static
    address 31.133.YYY.254
    netmask 255.255.255.128
  post-up route add default gw 31.133.YYY.129 metric 3
  pre-down route del default gw 31.133.YYY.129

auto eth0:2
allow-hotplug eth0
iface eth0 inet static
    address 31.133.ZZZ.229
    netmask 255.255.255.0
  post-up route add default gw 31.133.ZZZ.1 metric 4
  pre-down route del default gw 31.133.ZZZ.1

此配置不起作用。没有 post-up 和 pre-down，但有网关 - 也不起作用。我该怎么办？启动时，bind 和其他服务无法启动，因为它们找不到可用的接口。使用单个 IP 配置（第一个），服务器可以正常工作。

非常感谢您的建议。

我解决了这个问题。

/etc/init.d/接口：

auto lo eth0
iface lo inet loopback

auto eth0:0 eth0:1 eth0:2

allow-hotplug eth0
iface eth0 inet static
    address 31.133.MMM.47
    netmask 255.255.255.0
    broadcast 31.133.MMM.255
    network 31.133.MMM.0
    post-up route add default gw 31.133.MMM.1 metric 1
    pre-down route del default gw 31.133.MMM.1


iface eth0:0 inet static
    address 31.133.NNN.254
    netmask 255.255.255.128
    broadcast 31.133.NNN.255
    network 31.133.NNN.0
    post-up route add default gw 31.133.NNN.129 metric 2
    pre-down route del default gw 31.133.NNN.129


iface eth0:1 inet static
    address 31.133.KKK.254
    netmask 255.255.255.128
    broadcast 31.133.KKK.255
    network 31.133.KKK.0
    post-up route add default gw 31.133.KKK.129 metric 3
    pre-down route del default gw 31.133.KKK.129


iface eth0:2 inet static
    address 31.133.LLL.229
    netmask 255.255.255.0
    broadcast 31.133.LLL.255
    network 31.133.LLL.0
    post-up route add default gw 31.133.LLL.1 metric 4
    pre-down route del default gw 31.133.LLL.1

并且它有效！

感谢大家的帮助！
