Based on the enterchannel (Port binding) in linux-Linux Enterprise Application-Linux server application information, the following is a detailed description. Objective: Multiple NICs Virtualize one Nic so that the failure of one Nic does not affect network usage.
Steps:
1. Modify the eth0 and eth1 configuration files
Ifcfg-eth0
DEVICE = eth0
BOOTPROTO = none
ONBOOT = yes
USERCTL = no
MASTER = bond0
SLAVE = yes
Ifcfg-eth1
DEVICE = eth1
BOOTPROTO = none
ONBOOT = yes
USERCTL = no
MASTER = bond0
SLAVE = yes
2. Configure the virtual Nic
Vi/etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE = bond0
BOOTPROTO = none
BROADCAST = 192.168.1.255
IPADDR = 192.168.1.97
NETMASK = 255.255.255.0
NETWORK = 192.168.1.0
ONBOOT = yes
TYPE = Ethernet
GATEWAY = 192.168.1.1
USERCTL = no
3. Edit modules. conf.
Vi/etc/modules. conf
Alias bond0 bonding
Options bond0 miimon = 100 mode = 1 primary = eth0
4. Add rc. local
Modprobe bonding miimon = 100 mode = 1
