关于linux bonding

注：bonding modes简介

数字表示  文字表示  说明

0 balance-rr 负载平衡模式
具容错功能, 其中一张 Slave 网卡失效仍可持续运作

1 active-backup 同一时间只有单一 Slave 网卡激活
Active Slave 网卡失效时自动启用次一顺位 Slave 网卡

2 balance-xor *未研究*

3 broadcast 所有 Slave 网卡一齐收发网路数据包
具容错功能, 其中一张 Slave 网卡失效仍可持续运作

4 802.3ad *未研究*

5 balance-tlb 传出自动负载平衡
传入由 Current Active Slave 负责
具容错功能, 其中一张 Slave 网卡失效仍可持续运作

6 balance-alb 传出及传入皆自动负载平衡
具容错功能, 其中一张 Slave 网卡失效仍可持续运作

##添加下面两行
alias bond0 bonding
options bonding miimon=100 mode=1


##重启network服务：
[root@station18 ~]# service network restart


##查看IP地址：

另外一种配置方式:
[root@station18 ~]# more /etc/sysconfig/network-scripts/ifcfg-bond0 |

grep -v "#"
DEVICE=bond0
BOOTPROTO=static
ONBOOT=yes
BROADCAST=192.168.1.255
NETWORK=192.168.1.0
NETMASK=255.255.255.0
IPADDR=192.168.1.110
USERCTL=yes
GATEWAY=192.168.1.1
TYPE=Ethernet

[root@station18 ~]# more /etc/sysconfig/network-scripts/ifcfg-eth0 |

grep -v "#"
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
USERCTL=no

[root@station18 ~]# more /etc/sysconfig/network-scripts/ifcfg-eth1 |

grep -v "#"
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
USERCTL=no

4./etc/rc.d/rc.local中添加如下一行:
ifenslave bond0 eth0 eth1    //


[root@station18 ~]# tail -n 2 /etc/modprobe.conf
alias bond0 bonding
options bond0 miimon=100 mode=1    // 关于miimon和mode可以参考

[root@station18 ~]# ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc

pfifo_fast master bond0 qlen 1000
    link/ether 00:0c:29:77:fb:f5 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::20c:29ff:fe77:fbf5/64 scope link

    link/ether 00:0c:29:77:fb:f5 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::20c:29ff:fe77:fbf5/64 scope link
       valid_lft forever preferred_lft forever
4: sit0: <NOARP> mtu 1480 qdisc noop
    link/sit 0.0.0.0 brd 0.0.0.0
5: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc

noqueue
    link/ether 00:0c:29:77:fb:f5 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.110/24 brd 192.168.1.255 scope global bond0
    inet6 fe80::20c:29ff:fe77:fbf5/64 scope link
       valid_lft forever preferred_lft forever


或者下面三条命令：
[root@station18 ~]# modprobe bonding
[root@station18 ~]# ifconfig bond0 192.168.0.1 netmask 255.255.0.0
[root@station18 ~]# ifenslave bond0 eth0 eth1
