NIC bonding on Redhat/CentOS 6
1. 可选
for Redhat 5 and Centos 5
vi /etc/modprobe.conf
alias bond0 bonding#每个bonding interface一行
for Redhat 6 and Centos 6
vi/etc/modprobe.d/bonding.conf
alias bond0 bonding#每个bonding interface一行
2. vi /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
#NM_CONTROLLED="yes"
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.2.131
NETMASK=255.255.255.0
#GATEWAY=192.168.2.1
USERCTL=no
BONDING_OPTS="mode=1 miimon=100"#mode 1 = failover,Active-backup policy
mode=0表示load balancing (round-robin)为负载均衡方式，两块网卡都工作, 交换机上对应端口要配置LACP ( active ) -- etherchannel。
mode=1表示fault-tolerance (active-backup)提供冗余功能，工作方式是主备的工作方式,也就是说默认情况下只有一块网卡工作,另一块做备份.
3. vi /etc/sysconfig/network-scripts/ifcfg-eth0
#eth0
DEVICE=eth0
#NM_CONTROLLED="yes"
MASTER=bond0
SLAVE=yes
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
4. sed"s/eth0/eth1/g" ifcfg-eth0 > ifcfg-eth1
5. vi /etc/sysconfig/network，参考以下设置
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=test2.test.com
GATEWAY=192.168.2.1
vi /etc/resolv.conf，参考以下设置
search test.com
nameserver192.168.2.10
6. service network restart
7. cat /proc/net/bonding/bond0
8. vi /etc/sysconfig/network-scripts/route-bond0
