Bind multiple IP addresses to a single Nic In CentOS

Because it is in the same network segment of the Intranet, you only need to change IPADDR = XXXX. The details are as follows:

[Root @ webserver network-scripts] # pwd
/Etc/sysconfig/network-scripts

[Root @ webserver network-scripts] # cat ifcfg-eth0

NETMASK = 255.255.255.255.128

ONBOOT = yes
