Linux一個主機配多個IP 首先我們在linux下查看該主機的IP地址:#ifconfigeth0 Link encap:Ethernet HWaddr 00:16:8d:B7:6A:E0 inet addr:192.168.1.111 Bcast:192.168.1.255 Mask:255.255.252.0 inet6 addr: fd80::213:8eff:feb7:2ae0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7077 errors:0 dropped:0 overruns:0 frame:0 TX packets:54 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:654811 (639.4 KiB) TX bytes:6229 (6.0 KiB) Interrupt:10 Base address:0xb800 這裡我們只看到該主機只有一個IP地址,我們要在網卡eth0上再綁定另外一個IP,因為一般的機器它只有一張網卡,所以我們就在同一張網卡上進行多個IP的綁定。好了,我們開始做吧。1.首先進入網卡的設定檔#cd /etc/sysconfig/network-scripts2.複製網卡eth0的設定檔#cp ifcfg-eth0 ifcfg-eth0:03.修改ifcfg-eht0:0檔案#vi ifcfg-eth0:0將其中的IP地址改為你的另外一個IP地址,比如我的修改如下:DEVICE=eth0:0 #網卡的設定名稱,要跟檔案名稱一致BOOTPROTO=staticHWADDR=00:16:8d:B7:6A:E0IPADDR=192.168.1.112NETMASK=255.255.252.0GATEWAY=192.168.0.0ONBOOT=yesTYPE=Ethernet 注意的是,eth0:0的物理網卡地址必須要和eth0d物理網卡地址,即HWaddr要一致,因為是在同一網卡上綁定的多個IP。儲存好後,我們就可以 重啟網卡了.4.重新啟動網卡/etc/init.d/network restart 5.啟動後,再查看IP地址#ifconfigeth0 Link encap:Ethernet HWaddr 00:16:8d:B7:6A:E0 inet addr:192.168.1.111 Bcast:192.168.1.255 Mask:255.255.252.0 inet6 addr: fd80::213:8eff:feb7:2ae0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7077 errors:0 dropped:0 overruns:0 frame:0 TX packets:54 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:654811 (639.4 KiB) TX bytes:6229 (6.0 KiB) Interrupt:10 Base address:0xb800 eth0:0 Link encap:Ethernet HWaddr 00:16:8d:B7:6A:E0 inet addr:192.168.1.112 Bcast:192.168.1.255 Mask:255.255.252.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:10 Base address:0xb800 看看,機器是不是有兩個IP地址了啊,呵呵,可以試著用另外一台機器ping下~~~#ping 192.168.1.111PING 192.168.1.111 (192.168.1.111) 56(84) bytes of data.64 bytes from 192.168.1.111: icmp_seq=0 ttl=64 time=0.061 ms64 bytes from 192.168.1.111: icmp_seq=1 ttl=64 time=0.048 ms64 bytes from 192.168.1.111: icmp_seq=2 ttl=64 time=0.052 ms#ping 192.168.1.112PING 192.168.1.112 (192.168.1.112) 56(84) bytes of data.64 bytes from 192.168.1.112: icmp_seq=0 ttl=64 time=0.063 ms64 bytes from 192.168.1.112: icmp_seq=1 ttl=64 time=0.055 ms64 bytes from 192.168.1.112: icmp_seq=2 ttl=64 time=0.055 ms
