Redundant link Bond 1 application in Linux server

As we all know, Linux provides a powerful server function, but the server is very high on the link requirements, at least require 7*24 is connected. But once our server network card problem, or link problem, in this case, the server will not be normal access. Is there any way we can eliminate this phenomenon? The answer is yes, we can do Bond 1. The principle is that the server has two network cards, the two network cards bundled into a bond1, the common one IP address, when the main network card failure, another backup card immediately enabled.

Next, I'll do a bond 1 configuration.

======================================================================

To modify the network card parameters:

[Root@localhost ~]# Vim/etc/sysconfig/network-scripts/ifcfg-eth0

Device=eth0

Bootproto=dhcp

Onboot=yes

[Root@localhost ~]# Vim/etc/sysconfig/network-scripts/ifcfg-eth1

Device=eth1

Bootproto=dhcp

Onboot=yes

Establish and edit ifcfg-bond0 files:

[Root@localhost ~]# Touch/etc/sysconfig/network-scripts/ifcfg-bond0

[Root@localhost ~]# Vim/etc/sysconfig/network-scripts/ifcfg-bond0

Device=bond0

Bootproto=none

Onboot=yes

netmask=255.255.255.0

ipaddr=192.168.10.20

Call Bonding module:

[Root@localhost ~]# modprobe Bonding
