前言：這是我以RedHat 7.3為例來說明的，有可能系統版本不同，不過我覺得大同小異吧。哈。。。 1.進入目錄： [root@Linuxsir root]# cd /etc/sysconfig/network-scripts/ 2：ifcfg-eh0:0中的eh0:0是網卡的代號，當然你也可以用eh0:1之類的，隨你喜歡怎麼弄，但在eh0:X之前必須有ifcfg，也就是下面這種形式的，我們以eh0:0為例。 [root@Linuxsir root]#cp ifcfg-eth0 ifcfg-eth0:0 3,編輯ifcfg-eth0:0 [root@Linuxsir root]# vi ifcfg-eth0:0 ifcfg-eth0:0裡面有這樣的內容，你可以這樣設置，然後IP可以自己設置了。象我這樣設置也一樣。 # Please read /usr/share/doc/initscripts-*/sysconfig.txt # for the documentation of these parameters. USERCTL='no' NETMASK='255.255.255.0' -》子掩碼 BOOTPROTO='static' -》協議 DEVICE='eth0:0' -》虛擬網卡的代號 IPADDR='192.168.0.9' -》我自己設定的IP TYPE='Ethernet' onBOOT='yes' -》是否開機激活 NETWORK='192.168.0.0' -》網域 BROADCAST='192.168.0.255' -》廣播 4.保存退出，然後運行如下的命令，來激活虛擬的網卡。 [root@Linuxsir root]# ifup eh0:0 5.我們來查看我們虛擬的網卡是不是激活了，用ifconfig,也就是下面這樣的。 [root@Linuxsir network-scripts]# ifconfig eth0 Link encap:Ethernet HWaddr 00:E0:4C:00:C9:05 inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3 errors:0 dropped:0 overruns:0 frame:0 TX packets:54 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:180 (180.0 b) TX bytes:7157 (6.9 Kb) Interrupt:11 Base address:0x2000 eth0:0 Link encap:Ethernet HWaddr 00:E0:4C:00:C9:05 inet addr:192.168.0.9 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:11 Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:12 errors:0 dropped:0 overruns:0 frame:0 TX packets:12 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:846 (846.0 b) TX bytes:846 (846.0 b) 6.ping一下IP,就能知道我們做的是不是成功了。 [root@Linuxsir network-scripts]# ping 192.168.0.9 PING 192.168.0.9 (192.168.0.9) from 192.168.0.9 : 56(84) bytes of data. 64 bytes from 192.168.0.9: icmp_seq=1 ttl=255 time=0.097 ms 64 bytes from 192.168.0.9: icmp_seq=2 ttl=255 time=0.043 ms 64 bytes from 192.168.0.9: icmp_seq=3 ttl=255 time=0.043 ms 64 bytes from 192.168.0.9: icmp_seq=4 ttl=255 time=0.044 ms 64 bytes from 192.168.0.9: icmp_seq=5 ttl=255 time=0.043 ms --- 192.168.0.9 ping statistics --- 14 packets transmitted, 14 received, 0% loss, time 12996ms rtt min/avg/max/mdev = 0.039/0.046/0.097/0.016 ms [root@Linuxsir network-scripts]# ping 192.168.0.1 PING 192.168.0.1 (192.168.0.1) from 192.168.0.1 : 56(84) bytes of data. 64 bytes from 192.168.0.1: icmp_seq=1 ttl=255 time=0.069 ms 64 bytes from 192.168.0.1: icmp_seq=2 ttl=255 time=0.042 ms 64 bytes from 192.168.0.1: icmp_seq=3 ttl=255 time=0.040 ms 64 bytes from 192.168.0.1: icmp_seq=4 ttl=255 time=0.042 ms --- 192.168.0.1 ping statistics --- 7 packets transmitted, 7 received, 0% loss, time 5995ms rtt min/avg/max/mdev = 0.040/0.046/0.069/0.009 ms
