linux 中所有的设备都是文件.网卡也在文件中定义. IP的绑定也只需要更改文件. 网卡相关文件在目录: /etc/sysconfig/network-scripts 查询当前IP信息: ifconfig: eth0 Link encap:Ethernet HWaddr 00:50:56:AC:6B:0F inet addr:42.51.135.206 Bcast:42.51.135.255 Mask:255.255.255.0 inet6 addr: fe80::250:56ff:fead:6b0f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:374772 errors:0 dropped:0 overruns:0 frame:0 TX packets:35165 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:28759089 (27.4 MiB) TX bytes:4779278 (4.5 MiB) 在当前目录下有文件: ifcfg-eth0 在目录下新建文件: ifcfg-eth0:1 内容如下: DEVICE=eth0:1 IPADDR=42.51.138.1 NETMASK=255.255.255.0 HWADDR=00:50:56:AC:6B:0F NM_CONTROLLED=yes ONBOOT=yes BOOTPROTO=dhcp TYPE=Ethernet IPV6INIT=no USERCTL=no ifcfg-eth0:2 DEVICE=eth0:2 IPADDR=42.51.138.2 NETMASK=255.255.255.0 HWADDR=00:50:56:AC:6B:0F NM_CONTROLLED=yes ONBOOT=yes BOOTPROTO=dhcp TYPE=Ethernet IPV6INIT=no USERCTL=no ifcfg-eth0:3 DEVICE=eth0:3 IPADDR=42.51.138.3 NETMASK=255.255.255.0 HWADDR=00:50:56:AC:6B:0F NM_CONTROLLED=yes ONBOOT=yes BOOTPROTO=dhcp TYPE=Ethernet IPV6INIT=no USERCTL=no 重启网卡: service network restart 这时候再查看IP: eth0 Link encap:Ethernet HWaddr 00:50:56:AC:6B:0F inet addr:42.51.135.206 Bcast:42.51.135.255 Mask:255.255.255.0 inet6 addr: fe80::250:56ff:fead:6b0f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:384344 errors:0 dropped:0 overruns:0 frame:0 TX packets:35241 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:29462159 (28.0 MiB) TX bytes:4791402 (4.5 MiB) eth0:1 Link encap:Ethernet HWaddr 00:50:56:AC:6B:0F inet addr:42.51.138.1 Bcast:42.51.138.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth0:2 Link encap:Ethernet HWaddr 00:50:56:AC:6B:0F inet addr:42.51.138.2 Bcast:42.51.138.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth0:3 Link encap:Ethernet HWaddr 00:50:56:AC:6B:0F inet addr:42.51.138.3 Bcast:42.51.138.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 测试: 在其它机器上分别 ping 上面几个IP.
