这篇文章主要讲解了"CentOS下一张网卡怎么绑定多个IP"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"CentOS下一张网卡怎么绑定多个IP"吧！
CentOS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.
