Linux dual NIC Binding network Setup Method _unix Linux

Set the host name and domain name of the Linux host
/etc/hosts
Example
127.0.0.1 localhost.localdomain localhost

In general, the content of hosts in the host name (hostname) of the definition, each behavior of a host, each row consists of three parts, each part by a space separated. The lines at the beginning of the # number are described and are not interpreted by the system.

The first part: Network IP address;
Part II: Host name. Domain name, note the point between the host name and the domain name, such as Localhost.localdomain
The second part: host name (hostname alias), in fact, is the host name;

Of course, each line can also be two parts, is the host IP address and host name; like 192.168.1.195 Debian
=================================

Setting the Linux host Domain name resolution
/etc/resolv.conf
Example: (Up to 3 sets)
NameServer 202.96.134.133
NameServer 202.96.128.143
NameServer 202.96.68.38

=====================================
Set Network card Bindings
The first thing to edit is the NIC configuration file, which is located in the following directory:
/etc/sysconfig/network-scripts
Binding configuration file: Ifcfg-bond0 the contents are as follows:
Device=bond0
ipaddr=10.0.0.210
netmask=255.255.255.0
broadcast=10.0.0.255
network=10.0.0.0
gateway=10.0.0.1
Onboot=yes
Type=ethernet
==============================
Configuration file for Nic: Ifcfg-ethx contents are as follows:
Device=ethx
Onboot=yes
Bootproto=none
#MASTER =bond0
#slave =yes
===============================
When these are configured, you configure the/etc/modprobe.conf file and add the following:
Alias Bond0 Bonding
Options Bond0 miimon=100 mode=0
Note: Miimon is used for link monitoring. For example: miimon=100, then the system every 100MS monitoring link connection state, if there is a line does not pass on to another line; Mode's value represents the working mode, he has 0,1,2,3 four modes, commonly used for 0, 12 kinds.
Mode=0 indicates that the load balancing (round-robin) is loaded in a balanced way and both cards work.
Mode=1 means that fault-tolerance (active-backup) provides redundancy, working in a way that is normally done, which means that by default only one network card works and the other is backed up.
==================================================
Finally, edit the/etc/rc.d/rc.local file and add the following:
Ifenslave bond0 eth0 eth1
