下面是在RHEL6.6上配置双网卡绑定，在RHEL 6配置与RHEL 5配置有一点不相同，只是修改的文件不一样，原理是一样的，下面以主备来测试：
1，版本介绍
|
[root@localhost ~]# lsb_release -a LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: RedHatEnterpriseServer Description: Red Hat Enterprise Linux Server release 6.6 (Santiago) Release: 6.6 Codename: Santiago |
2，加载bonding模块
默认双网卡绑定模块是没有加载的，第一次需要手动加载，以后会自动加载，不需要做其它的配置，在RHEL 5中需要把加载手动写到/etc/rc.local文件中，每次启动的时候自动加载。
|
[root@localhost modules]# lsmod|grep bond [root@localhost modules]# modprobe –first-time bonding [root@localhost modules]# lsmod|grep bonding bonding 130997 0 8021q 25527 1 bonding ipv6 334932 272 bonding,ip6t_REJECT,nf_conntrack_ipv6,nf_defrag_ipv6 |
3，配置网卡配置文件
|
这里可以不用禁用networkmanager服务，但是是需要在配置文件中增加 NM_CONTROLLED=no此参数，不过还是建议禁用。
echo "DEVICE=bond0 IPADDR=192.168.111.30 NETMASK=255.255.255.0 ONBOOT=yes BOOTPROTO=none USERCTL=no NM_CONTROLLED=no IPV6INIT=no #from mos 1642955.1 BONDING_OPTS=\"mode=active-backup miimon=100 downdelay=5000 updelay=5000 num_grat_arp=100\"">/etc/sysconfig/network-scripts/ifcfg-bond0
echo "DEVICE=eth0 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no IPV6INIT=no HOTPLUG=no CONNECTED_MODE=yes NM_CONTROLLED=no">/etc/sysconfig/network-scripts/ifcfg-eth0
echo "DEVICE=eth1 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no IPV6INIT=no HOTPLUG=no CONNECTED_MODE=yes NM_CONTROLLED=no">/etc/sysconfig/network-scripts/ifcfg-eth1
echo "DEVICE=bond1 IPADDR=192.168.112.30 NETMASK=255.255.255.0 ONBOOT=yes BOOTPROTO=none USERCTL=no IPV6INIT=no NM_CONTROLLED=no #from mos 1642955.1， BONDING_OPTS=\"mode=active-backup miimon=100 downdelay=5000 updelay=5000 num_grat_arp=100\"">/etc/sysconfig/network-scripts/ifcfg-bond1
echo "DEVICE=eth2 BOOTPROTO=none ONBOOT=yes MASTER=bond1 SLAVE=yes USERCTL=no IPV6INIT=no HOTPLUG=no CONNECTED_MODE=yes NM_CONTROLLED=no">/etc/sysconfig/network-scripts/ifcfg-eth2
echo "DEVICE=eth3 BOOTPROTO=none ONBOOT=yes MASTER=bond1 SLAVE=yes USERCTL=no IPV6INIT=no HOTPLUG=no CONNECTED_MODE=yes NM_CONTROLLED=no">/etc/sysconfig/network-scripts/ifcfg-eth3
重启网卡服务 /etc/init.d/network restart， 生产环境建议使用ifup/ifdown来操作。不会影响其它的网卡。 |
4，查看绑定信息

重启服务器测试 重启后服务正常。 |
5，断网卡测试
|
[root@www.htz.pw bonding]# mii-tool eth0 eth0: no link [root@www.htz.pw bonding]# mii-tool eth1 eth1: negotiated 100baseTx-FD, link ok
这里可以看到，已经自动切换到eth1上面 [root@www.htz.pw network-scripts]# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009)
Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: eth1 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 5000 Down Delay (ms): 5000
