RedHat6.5雙網卡bonding

環境:RHEL 6.5

注意:此處的機器環境是3網卡,我用eth0連ssh的,但是一直掉...

需要關閉NetworkManager,並將其設置為開機不啟動(這個玩意兒真煩)
1. 創建bond0文件:

1. vim /etc/sysconfig/network-scripts/ifcfg-bond0
2. DEVICE=bond0
3. ONBOOT=yes
4. BOOTPROTO=static
5. TYPE=Ethernet
6. IPADDR=192.168.115.50
7. NETMASK=255.255.255.0

2. 修改網卡配置:

1. vim /etc/sysconfig/network-scripts/ifcfg-eth1

1. DEVICE=eth1
2. ONBOOT=yes
3. BOOTPROTO=none
4. MASTER=bond0
5. SLAVE=yes
6. USERCTL=no

1. vim /etc/sysconfig/network-scripts/ifcfg-eth2
2. DEVICE=eth2
3. ONBOOT=yes
4. BOOTPROTO=none
5. MASTER=bond0
6. SLAVE=yes
7. USERCTL=no

3. 加載bond模塊,在配置文件末尾添加參數

1. vim /etc/modprobe.d/dist.conf

1. 1. alias bond0 bonding
   2. options bond0 mode=0 miimon=100

解析:

1. mode 0表示為負載均衡模式,兩塊網卡都工作
2. mode 1表示冗余模式,一塊是工作,一塊冗余
3. miimon表示系統檢查間隔時間,單位是ms,
4. 例如:每100ms檢查一次,當發現一條線路不通,就轉入另一條

4. 將bond0設置為開機自動加載

1. vim /etc/rc.local
2. ifenslave bond0 eth1 eth2

5. reboot ,之後使用ifconfig查看bond0和eht1,eth2兩塊網卡的MAC地址是否相同 注意不管bond 0 還是bond 1,都是三者相同,因為在交換機的時候需要識別MAC然後發送到對應的MAC上,不相同是不對的, 假如不相同,回去檢查NetworkManager是不是關了 來個標准的: 注意

1. [root@oratest0 ~]# ifconfig
2. bond0 Link encap:EthernetHWaddr00:0C:29:44:52:23

6. 查看bond狀態,能實時查看兩塊網卡的工作狀態

1. cat /proc/net/bonding/bond0
