Log on to SSH as follows:

Copy codeThe code is as follows:
Vi/etc/sysconfig/network-scripts/ifcfg-eth0: 0

The second IP address is

Copy codeThe code is as follows:
Vi/etc/sysconfig/network-scripts/ifcfg-eth0: 1

The third IP address is
Ifcfg-eth0: 2 (and so on)

Copy codeThe code is as follows:
DEVICE = eth0: 0 Nic DEVICE name
Onboot = YES random start
BOOTPROTO = static IP address allocation
IPADDR = *. * The IP address to be added
NETMASK = 255.255.255.0 subnet mask (subject to actual conditions)
GATEWAY = *. * route

If the IP address is continuous, you can use the following method.

Copy codeThe code is as follows:
Vi/etc/sysconfig/network-scripts/ifcfg-eth0-range
DEVICE = eth0
BOOTPROTO = static
IPADDR_START = start IP address
IPADDR_END = end IP address
CLONENUM_START = start number of the NIC
NETMASK = subnet mask
ONBOOT = yes

Save the file and restart the network service.
