Oracle 11gR2 RAC 单网卡转双网卡绑定配置步骤

添加如下语句

运行

[root@RAC1 ~]# source .bash_profile

使修改生效

目前两个节点的eth0 对应Public IP，eth1 对应Private IP，目标是eth0 与eht1 绑定bond0对应Public IP，eth3 与eth4 绑定bond1对应Private IP,具体IP地址不变。

一旦修改网卡绑定之后，RAC就不能启动，也就不能进行修改，所以我们这里先修改PUBLIC和 Private配置。修改完之后再绑定双网卡。

删除当前配置

创建bond0配置文件

写入

创建bond1配置文件

写入

修改eth0

修改eth1

修改eth2

修改eth3

添加

添加

RAC1的网卡绑定 *** 作完成

RAC2的网卡绑定 *** 作步骤与RAC1相同，注意修改对应的bond0与bond1的IP地址即可。

关闭虚拟机，添加一块虚拟网卡：

启动虚拟机后，此时还查看不到新加的网卡：

改下DEVICE,HWADDR,IPADDR,删除GATEWAY

修改后：

[root@slave2 network-scripts]# cat ifcfg-eth1

注意：用于内连的网卡不能设置网关，否则会连不上网。

注意：MAC地址HWADDR一定得和/etc/udev/rules.d/70-persistent-net.rules文件中的eth1保持一致，否则servicenetwork restart会报错：
