一臺主機虛擬多個ip

小亮520cl發表於2015-08-11
複製一份eth0的配置檔案為eth0:0在去修改一個DEVICE=eth0:0
下面的就按需分配了!
儲存後用ifup eth0:0就可以啟動了!
這樣就可以給一塊網路卡配兩個IP地址了!
多個ip就複製多份

點選(此處)摺疊或開啟

  1. [rootgc1:/root]$ more /etc/sysconfig/network-scripts/ifcfg-eth0
  2. ifcfg-eth0 ifcfg-eth0:0 ifcfg-eth0:1

點選(此處)摺疊或開啟

  1. [rootgc1:/root]$ more /etc/sysconfig/network-scripts/ifcfg-eth0
  2. # Please read /usr/share/doc/initscripts-*/sysconfig.txt
  3. # for the documentation of these parameters.
  4. TYPE=Ethernet
  5. DEVICE=eth0
  6. HWADDR=08:00:27:70:78:0e
  7. BOOTPROTO=none
  8. ONBOOT=yes
  9. USERCTL=no
  10. IPV6INIT=no
  11. PEERDNS=yes
  12. NETMASK=255.255.255.0
  13. IPADDR=192.168.6.114
  14. GATEWAY=192.168.6.1

  1. [rootgc1:/root]$ more /etc/sysconfig/network-scripts/ifcfg-eth0:0
  2. # Please read /usr/share/doc/initscripts-*/sysconfig.txt

  4. TYPE=Ethernet
  5. DEVICE=eth0:0
  6. BOOTPROTO=none
  7. USERCTL=no
  8. IPV6INIT=no
  9. PEERDNS=yes
  10. NETMASK=255.255.255.0
  11. IPADDR=192.168.6.104
  12. GATEWAY=192.168.6.1
  13. ONPARENT=yes

方法二：直接在eth0 ip下面加一個也可以
方法三：圖形化介面


方法四：（service network restart重啟網路卡會失效，還是得加到/etc/sysconfig/network-scripts/下去，，所以還是用前幾種方法吧！）
