ubuntu伺服器採集多IP段

⑴ 如何給Ubuntu網站綁定多個IP，怎麼給Ubuntu伺服器設置多IP

多個不同IP段的 /etc/network/interfaces 配置文件的範例如下：
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 8.8.8.2
netmask 255.255.255.248
gateway 8.8.8.1 要注意這里，多個不同IP段，只要1個gateway配置即可，其他IP不需要配置gateway

auto eth0:0
iface eth0:0 inet static
address 8.8.8.3
netmask 255.255.255.248

auto eth0:1
iface eth0:1 inet static
address 8.8.8.4
netmask 255.255.255.248

auto eth0:2
iface eth0:2 inet static
address 8.8.8.5
netmask 255.255.255.248

auto eth0:3
iface eth0:3 inet static
address 8.8.8.6
netmask 255.255.255.248

auto eth0:4
iface eth0:4 inet static
address 6.6.6.130 注意這里，雖然這是不同的IP段，但是不需要配置gateway，只需要配置netmask即可
netmask 255.255.255.224

auto eth0:5
iface eth0:5 inet static
address 6.6.6.131
netmask 255.255.255.224

更多ip也類似配置即可。
配置文件完成後，用命令 /etc/init.d/networking restart 重啟網路，不需要reboot重啟伺服器。 /etc/init.d/networking restart 重啟網路的時候，如果你的配置文件有錯誤，那麼他會提示你。比如IP重復了，書寫錯誤了，等等。在執行此命令前，一定要小心檢查interfaces配置文件，不然可能就把網路弄癱瘓，那時候就需要機房的工作人員去處理，十分麻煩。

/etc/init.d/networking restart錯誤分析案例：
[email protected]:/etc/network# /etc/init.d/networking restart
* Reconfiguring network interfaces...
/etc/network/interfaces:165: interface eth0:28 declared allow-auto twice
ifdown: couldn't read interfaces file "/etc/network/interfaces"
/etc/network/interfaces:165: interface eth0:28 declared allow-auto twice
ifup: couldn't read interfaces file "/etc/network/interfaces"
...fail!

說明eth0:28有重復，解決辦法：vi interfaces找到eth0:28，刪除掉重復的

[email protected]:/etc/network# /etc/init.d/networking restart
* Reconfiguring network interfaces...
/etc/network/interfaces:166: plicate interface
ifdown: couldn't read interfaces file "/etc/network/interfaces"
/etc/network/interfaces:166: plicate interface
ifup: couldn't read interfaces file "/etc/network/interfaces"
...fail!

說明166行有重復，解決辦法：vi interfaces找到166行(set number)，刪除掉重復的

[email protected]:/etc/network# /etc/init.d/networking restart
* Reconfiguring network interfaces...
/etc/network/interfaces:162: plicate interface
ifdown: couldn't read interfaces file "/etc/network/interfaces"
/etc/network/interfaces:162: plicate interface
ifup: couldn't read interfaces file "/etc/network/interfaces"

說明162行有重復，解決辦法：vi interfaces找到166行(set number)，刪除掉重復的
