Redhat创建bond DEVICE=bond0 ONBOOT=yes BOOTPROTO=static TYPE=Ethernet IPADDR=192.168.5.50 NETMASK=255.255.255.0 PREFIX=24 GATEWAY=192.168.5.2 DNS1=192.168.5.2 DEFROUTE=yes
2、vim /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 ONBOOT=yes BOOTPROTO=none MASTER=bond0 SLAVE=yes USERCTL=no
3、vim /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 ONBOOT=yes BOOTPROTO=none MASTER=bond0 SLAVE=yes USERCTL=no
加载bond模块 4、vim /etc/modprobe.d/dist.conf alias bond0 bonding options bond0 mode=0 miimon=100
mode 0表示为负载均衡模式,两块网卡都工作
mode 1表示冗余模式,一块是工作,一块冗余
miimon表示系统检查间隔时间,单位是ms,
例如:每100ms检查一次,当发现一条线路不通,就转入另一条
5、设置bond0开机自启 vim /etc/rc.local ifenslave bond0 eth0 eth1 ———————————————————- # grep bond0 /etc/modprobe.conf alias bond0 bonding
cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes
cat /etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes
cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0 BOOTPROTO=dhcp ONBOOT=yes BONDING_OPTS=”mode=4 miimon=100 lacp_rate=1” 启动bond0
ifup bond0
[root@lmsin ~]# cat /proc/net/bonding/bond1 Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009)
Bonding Mode: load balancing (round-robin) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0

那mode值改下。。mode 1、5、6不需要交换机设置 mode 0、2、3需要交换机设置静态聚合，mode 4需要交换机支持802.3ad
不客气，，弄完查看下。。/etc/modprobe.conf 这里面也可以加，alias bond0 bonding
options bond0 miimon=100 mode=1 配置完service network restart 一下。。
echo “ifenslave bond0 eth0 eth1”» /etc/rc.d/rc.local 这个在配置好bond0后也可以加进去。。应该就这些了。。
