CentOS binds eth01/eth02 to an IP address.

CentOS binds eth01/eth02 to an IP address.

Operation example: bind eth01/eth02 to an IP address

(1) Add the following content to the configuration file/etc/modprobe. conf of the kernel module:

######BondingStart###### alias bond0bonding optionsbondingmax_bonds=1 ######BondingEnd########

(2) establish the bonding Nic file/etc/sysconfig/network-scripts/ifcfg-bond0, the configuration is as follows:

DEVICE=bond0 ONBOOT= yes BOOTPROTO=static IPADDR=192.168.100.21 NETMASK=255.255.255.0 USERCTL=no BONDING_OPTS= "mode=1miimon=100primary=eth01"

* Bonding_opts parameter reference:

(3) modify the NIC configuration file of eth01:

DEVICE=eth01 MASTER=bond0 SLAVE= yes HWADDR=54:22:22:00:7A:37:CE ONBOOT= yes

Modify the NIC configuration file of eth02:

DEVICE=eth02 MASTER=bond0 SLAVE= yes HWADDR=54:22:22:00:7A:37:CE ONBOOT= yes

(4) import the bonding driver and restart the network service.
