Server: add IP to network card in batch under Centos system

Add IP to the network card one by one under the Centos system

Create similar ifcfg-eth0:x files under / etc/sysconfig/network-scripts/, for example:

DEVICE=eth0:0

ONBOOT=yes

BOOTPROTO=static

IPADDR=192.168.1.100

NETMASK=255.255.255.0

NETWORK=192.168.1.1

BROADCAST=192.168.0.255

TYPE=Ethernet

Batch method can be used if it is a large number of continuous IP.

1. Establish / etc/sysconfig/network-scripts/ifcfg-eth0-range0

two。 Add the following to ifcfg-eth0-range0:

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=static

IPADDR_START=192.168.1.100

IPADDR_END=192.168.1.200

CLONENUM_START=0

GATEWAY= Gateway address

NETMASK= subnet mask

NO_ALIASROUTING=yes

The above content will add the IP range segment from IPADDR_START (192.168.1.100) to IPADDR_END (192.168.1.200). The value of CLONENUM_START is the network card of the previous IP alias. You can view the number after the last eth0: by ifconfig. The above example is the corresponding eth0:0.

To add multiple IP range, just set up ifcfg-eth0-range1, ifcfg-eth0-range2 in sequence.

Restarting the network after modification is complete:

/ sbin/service network restart
