Linux系统在线增加多个ip(转)[@more@]首先查看ip 代码: linuxedu.net# ifconfig eth0 Link encap:Ethernet HWaddr 00:50:BA:EF:21:E2 inet addr:192.168.1.1 Bcast:192.168.1.255 mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3433865 errors:0 dropped:0 overruns:0 frame:0 TX packets:2730922 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:2610363482 (2489.4 Mb) TX bytes:577832769 (551.0 Mb) Interrupt:11 Base address:0xc000 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:811139 errors:0 dropped:0 overruns:0 frame:0 TX packets:811139 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2007636558 (1914.6 Mb) TX bytes:2007636558 (1914.6 Mb) 添加ip 代码: ifconfig eth0:0 192.168.1.2 netmask 255.255.255.255 up 在查看. 代码: linuxedu.net# ifconfig eth0 Link encap:Ethernet HWaddr 00:50:BA:EF:21:E2 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3433865 errors:0 dropped:0 overruns:0 frame:0 TX packets:2730922 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:2610363482 (2489.4 Mb) TX bytes:577832769 (551.0 Mb) Interrupt:11 Base address:0xc000 eth0:0 Link encap:Ethernet HWaddr 00:50:BA:EF:21:E2 inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.255 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3433471 errors:0 dropped:0 overruns:0 frame:0 TX packets:2730637 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:2610321034 (2489.3 Mb) TX bytes:577696691 (550.9 Mb) Interrupt:11 Base address:0xc000 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:811139 errors:0 dropped:0 overruns:0 frame:0 TX packets:811139 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2007636558 (1914.6 Mb) TX bytes:2007636558 (1914.6 Mb) 最后写到文件里,使从新启动时生效. vi /etc/sysconfig/network-scripts/ifcfg-eth0:0 代码: DEVICE=eth0:0 ONBOOT=yes BOOTPROTO=static IPADDR=192.168.1.2 去掉ip 代码: ifconfig eth0:0 192.168.1.2 netmask 255.255.255.255 down rm /etc/sysconfig/network-scripts/ifcfg-eth0:0 完成.
