RHEL6.3 X86(64位）网卡做bonding

1.      网卡做bond

本次是将eth0和eth6做成一个bond0

1.       Bond0

[root@EDEVAPP3 ~]# more /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0

ONBOOT=yes

BOOTPROTO=static

IPADDR=192.168.137.134

NETMASK=255.255.255.192

GATEWAY=192.168.137.190

2.       Eth0

[root@EDEVAPP3 ~]# more /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

ONBOOT=yes

HWADDR=08:9E:01:62:9F:AA

MASTER=bond0

SLAVE=yes

3.       Eth6

[root@EDEVAPP3 ~]# more /etc/sysconfig/network-scripts/ifcfg-eth6

DEVICE=eth6

BOOTPROTO=none

HWADDR="68:05:CA:05:B6:D4"

ONBOOT=yes

MASTER=bond0

SLAVE=yes

4.       修改下面参数

[root@EDEVAPP3 ~]#vi /etc/modprobe.d/dist.conf

增加

alias bond0 bonding

options bond0 miimon=100 mode=1

--如果是双主交换机，且是主备模式的，两块网卡接到两个交换机上时，最好用mode=1，即主备模式，如果是load balance模式（mode=0)的话，可能会出现丢包的情况。

[root@EDEVAPP3 etc]# vi /etc/rc.d/rc.local

增加

ifenslave bond0 eth0 eth6

5.       将 NetworkManager服务关闭

[root@EDEVAPP2 network-scripts]# service NetworkManager stop

[root@EDEVAPP2 network-scripts]#Chkconfig –level 2345 NetworkManager off

--防火墙也需要设置好，可以关闭，selinux可以禁用掉。

6.       重启机器

配置完成后必须重启机器才能生效。

 

7.       一些检查

root@EDEVAPP3 etc]# ethtool eth0
