之前写过一篇双网卡绑定的文章，如下：
http://blog.csdn.net/tianlesoftware/article/details/6189639
http://blog.csdn.net/tianlesoftware/article/details/5362925
这篇看一个完整的RAC修改网卡绑定的例子。
一．原RAC信息
数据库：11.2.0.3
操作系统: Redhat 5.8
[root@rac1 ~]# cat /etc/hosts
127.0.0.1 localhost
192.168.16.200 rac1 rac1-public
192.168.0.100 rac1-priv
192.168.16.201 rac1-vip
192.168.16.202 rac2 rac2-public
192.168.0.200 rac2-priv
192.168.16.203 rac2-vip
192.168.16.207 rac-scan
每个节点的服务器有4个网卡。 eth0对应Public IP，eth1 对应Private IP。
[root@rac1 ~]# srvctl config nodeapps
Network exists:1/192.168.16.0/255.255.255.0/eth0, type static
VIP exists:/rac1-vip/192.168.16.201/192.168.16.0/255.255.255.0/eth0, hosting node rac1
VIP exists:/rac2-vip/192.168.16.203/192.168.16.0/255.255.255.0/eth0, hosting node rac2
GSD exists
ONS exists: Local port 6100, remote port6200, EM port 2016
[root@rac1 ~]# srvctl config nodeapps -nrac1 -a
-n <node_name> option has beendeprecated.
Network exists:1/192.168.16.0/255.255.255.0/eth0, type static
VIP exists: /rac1-vip/192.168.16.201/192.168.16.0/255.255.255.0/eth0,hosting node rac1
[root@rac1 ~]# srvctl config nodeapps -nrac2 -a
-n <node_name> option has beendeprecated.
Network exists:1/192.168.16.0/255.255.255.0/eth0, type static
VIP exists: /rac2-vip/192.168.16.203/192.168.16.0/255.255.255.0/eth0,hosting node rac2
[root@rac1 ~]#
二．修改RAC 配置
之前的测试是先修改双网卡的绑定，但是一旦修改之后，RAC就不能启动，也就不能进行修改，所以我们这里先修改。修改完之后在该双网卡。
2.1 备份OCR和VOTINGDISK
[root@rac1 ~]# crsctl query css votedisk

2.1 修改网卡和IP信息

2.1.2 查看当前配置
[root@rac1 ~]# oifcfg getif -global
eth1 192.168.0.0 global cluster_interconnect
eth0 192.168.16.0 global public
2.1.3 修改PUBLIC和 Private信息
--删除当前配置
[root@rac1 ~]# oifcfg delif -global eth0
[root@rac1 ~]# oifcfg delif -global eth1
PRIF-31: Failed to deletethe specified network interface because it is the last private interface
--这里我们要先添加才能删除。
[root@rac1 ~]# oifcfg getif
eth1 192.168.0.0 global cluster_interconnect
[root@rac1 ~]# oifcfg setif -globalbond0/192.168.16.0:public
[root@rac1 ~]# oifcfg setif -globalbond1/192.168.0.0:cluster_interconnect
[root@rac1 ~]# oifcfg getif
eth1 192.168.0.0 global cluster_interconnect
bond0 192.168.16.0 global public
bond1 192.168.0.0 global cluster_interconnect
[root@rac1 ~]# oifcfg delif -global eth1
[root@rac1 ~]# oifcfg getif
bond0 192.168.16.0 global public
bond1 192.168.0.0 global cluster_interconnect
2.1.4 修改VIP
[root@rac1 ~]# srvctl modify nodeapps -nrac1 -A 192.168.16.201/255.255.255.0/bond0
PRKO-2200 : Invalid interface specified oncommand line: bond0
--提示bond0没有激活，先把bond0的配置信息写好，激活，先改我们CRS的信息：
[root@rac1 network-scripts]# ifup bond0
--再次修改就ok：
[root@rac1 ~]# srvctl modify nodeapps -nrac1 -A 192.168.16.201/255.255.255.0/bond0
[root@rac1 ~]# srvctl modify nodeapps -nrac2 -A 192.168.16.203/255.255.255.0/bond0
[root@raw1 bin]# ./oifcfg delif -globaleth0
[root@raw1 bin]# ./oifcfgdelif -global eth1
[root@raw1 bin]# ./oifcfg getif
2.1.5 检查监听等配置中的IP 信息
因为我这里只是修改了一下网卡的名称，所以不需要检查，IP地址是一样的。
三．双网卡绑定配置
3.1 停止RAC
# crsctl stop crs
3.1 节点1操作
创建/etc/sysconfig/network-scripts/ifcfg-bond0文件，内容如下：
BOOTPROTO=none
BROADCAST=192.168.16.255
IPADDR=192.168.16.200
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
GATEWAY=192.168.16.254
USERCTL=no
IPV6INIT=no
PEERDNS=yes
创建/etc/sysconfig/network-scripts/ifcfg-bond1文件，内容如下：
BOOTPROTO=none
BROADCAST=192.168.0.255
IPADDR=192.168.0.100
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
GATEWAY=192.168.0.254
USERCTL=no
IPV6INIT=no
PEERDNS=yes
分别修改原来网卡配置文件的信息，删除其中的IP 地址、子网掩码等信息
[root@rac1 network-scripts]# cat ifcfg-eth0
# Broadcom Corporation NetXtreme BCM5720Gigabit Ethernet PCIe
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
[root@rac1 network-scripts]# cat ifcfg-eth1
# Broadcom Corporation NetXtreme BCM5720Gigabit Ethernet PCIe
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
[root@rac1 network-scripts]# cat ifcfg-eth2
# Broadcom Corporation NetXtreme BCM5720Gigabit Ethernet PCIe
DEVICE=eth2
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
[root@rac1 network-scripts]# cat ifcfg-eth3
# Broadcom Corporation NetXtreme BCM5720Gigabit Ethernet PCIe
DEVICE=eth3
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
[root@rac1 network-scripts]#
在/etc/modprobe.conf文件中添加如下内容：
alias bond1 bonding
options bond0 miimon=100 mode=0
options bond1 miimon=100 mode=0
说明：
（1）、miimon 是链路监测的时间间隔单位是毫秒，miimon=100的意思就是，每100毫秒检测网卡和交换机之间是否连通，如不通则使用另外的链路。
（2)、mode=0 表示负载均衡方式，两块网卡都工作，需要交换机作支持
mode=1 表示冗余方式，网卡只有一个工作，一个出问题启用另外的
mode=6 表示负载均衡方式，两块网卡都工作，不需要交换机作支持
2.2 节点2操作
创建/etc/sysconfig/network-scripts/ifcfg-bond0文件，内容如下：
DEVICE=bond0
BOOTPROTO=none
BROADCAST=192.168.16.255
IPADDR=192.168.16.202
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
GATEWAY=192.168.16.254
USERCTL=no
IPV6INIT=no
PEERDNS=yes
创建/etc/sysconfig/network-scripts/ifcfg-bond1文件，内容如下：
DEVICE=bond1
BOOTPROTO=none
BROADCAST=192.168.0.255
IPADDR=192.168.0.200
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
GATEWAY=192.168.0.254
USERCTL=no
IPV6INIT=no
PEERDNS=yes
分别修改原来网卡配置文件的信息，删除其中的IP 地址、子网掩码等信息
[root@rac2 network-scripts]# cat ifcfg-eth0
# Broadcom Corporation NetXtreme BCM5720Gigabit Ethernet PCIe
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
[root@rac2 network-scripts]# cat ifcfg-eth1
# Broadcom Corporation NetXtreme BCM5720Gigabit Ethernet PCIe
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
[root@rac2 network-scripts]# cat ifcfg-eth2
# Broadcom Corporation NetXtreme BCM5720Gigabit Ethernet PCIe
DEVICE=eth2
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
[root@rac2 network-scripts]# cat ifcfg-eth3
# Broadcom Corporation NetXtreme BCM5720Gigabit Ethernet PCIe
DEVICE=eth3
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
[root@rac2 network-scripts]#
alias bond0bonding
alias bond1 bonding
options bond0 miimon=100 mode=0
options bond1 miimon=100 mode=0
说明：
（1）、miimon 是链路监测的时间间隔单位是毫秒，miimon=100的意思就是，每100毫秒检测网卡和交换机之间是否连通，如不通则使用另外的链路。
（2)、mode=0 表示负载均衡方式，两块网卡都工作，需要交换机作支持
mode=1 表示冗余方式，网卡只有一个工作，一个出问题启用另外的
mode=6 表示负载均衡方式，两块网卡都工作，不需要交换机作支持
2.3. 执行绑定
--节点1执行绑定：
[root@rac1 network-scripts]# ifenslavebond0 eth1 eth0
Illegal operation; the specified masterinterface 'bond0' is not up.
[root@rac1 network-scripts]# ifup bond0
[root@rac1 network-scripts]# ifenslavebond0 eth1 eth0
[root@rac1 network-scripts]#
[root@rac1 network-scripts]# ifup bond1
[root@rac1 network-scripts]# ifenslavebond1 eth2 eth3
--节点2执行绑定：
[root@rac2 network-scripts]# ifup bond0
[root@rac2 network-scripts]# ifup bond1
[root@rac2 network-scripts]# ifenslavebond0 eth1 eth0
[root@rac2 network-scripts]# ifenslavebond1 eth2 eth3
[root@rac2 network-scripts]#
2.4 设置开机自动绑定
在2个节点分别将如下参数添加到/etc/rc.local中，让开机自动绑定：
ifenslave bond0 eth0 eth1
ifenslave bond1 eth2 eth3
2.5 重新网络
[root@rac1 network-scripts]# servicenetwork restart
[root@rac2 network-scripts]# servicenetwork restart
绑定网卡的启动与关闭：
# ifdown bond0
#ifup bond0
2.6 查看网卡信息
