Oracle 11gR2 RAC 单网卡转双网卡绑定配置步骤

---

一、修改root用户环境变量

[root@RAC1 ~]# vi  .bash_profile

添加如下语句

JAVA_HOME=/usr/local/java
export JAVA_HOME
ORACLE_BASE=/u01/app/grid
export ORACLE_BASE
ORACLE_HOME=/u01/app/11.2.0/grid
export ORACLE_HOME
ORACLE_PATH=/u01/app/oracle/common/oracle/sql
export ORACLE_PATH
ORACLE_TERM=xterm
export ORACLE_TERM
NLS_DATE_FORMAT="DD-MON-YYYY HH24:MI:SS"
export NLS_DATE_FORMAT
TNS_ADMIN=$ORACLE_HOME/network/admin
export TNS_ADMIN
PATH=.:${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE
CLASSPATH=${CLASSPATH}:ORACLE_HOME/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export CLASSPATH
THREADS_FLAG=native
export THERADS_FLAG
export TEMP=/tmp
export TMPDIR=/tmp

运行
[root@RAC1 ~]# source .bash_profile
使修改生效

二、原RAC信息

[root@RAC1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

#eth0 - Public IP
10.5.10.2   rac1
10.5.10.3   rac2

#eth1 - Private IP
8.8.8.1  rac1-priv
8.8.8.2  rac2-priv

#VIP
10.5.10.4    rac1-vip
10.5.10.5    rac2-vip

#SCAN
10.5.10.6    rac-cluster-scan

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。

三、修改RAC配置

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。

---

当前Public和 Private信息

[root@RAC1 ~]# cd /u01/app/11.2.0/grid/bin/
[root@RAC1 bin]# oifcfg getif -global
eth0  10.5.10.0  global  public
eth1  8.0.0.0  global  cluster_interconnect
[root@RAC1 bin]# srvctl config nodeapps
网络存在: 1/10.5.10.0/255.255.255.0/eth0, 类型 static
VIP 存在: /10.5.10.4/10.5.10.4/10.5.10.0/255.255.255.0/eth0, 托管节点 rac1
VIP 存在: /10.5.10.5/10.5.10.5/10.5.10.0/255.255.255.0/eth0, 托管节点 rac2
GSD 已存在
ONS 存在: 本地端口 6100, 远程端口 6200, EM 端口 2016
[root@RAC1 bin]# srvctl config nodeapps -n rac1 -a
-n  选项已过时。
网络存在: 1/10.5.10.0/255.255.255.0/eth0, 类型 static
VIP 存在: /10.5.10.4/10.5.10.4/10.5.10.0/255.255.255.0/eth0, 托管节点 rac1
[root@RAC1 bin]#  srvctl config nodeapps -n rac2 -a
-n  选项已过时。
网络存在: 1/10.5.10.0/255.255.255.0/eth0, 类型 static
VIP 存在: /10.5.10.5/10.5.10.5/10.5.10.0/255.255.255.0/eth0, 托管节点 rac2

修改Public和 Private信息

删除当前配置

[root@RAC1 ~]# cd /u01/app/11.2.0/grid/bin/
[root@RAC1 bin]# oifcfg delif -global eth0
[root@RAC1 bin]# oifcfg delif -global eth1
PRIF-31: Failed to deletethe specified network interface because it is the last private interface

目前无法删除Private 信息，需要先添加再删除

[root@RAC1 bin]# oifcfg setif -global bond0/10.5.10.0:public
[root@RAC1 bin]# oifcfg setif -global bond1/8.0.0.0:cluster_interconnect
[root@RAC1 bin]# oifcfg delif -global eth1
[root@RAC1 bin]# oifcfg getif
bond0  10.5.10.0  global  public
bond1  8.0.0.0  global  cluster_interconnect

四、双网卡绑定配置

停止RAC

[root@RAC1 bin]# crsctl stop crs

RAC1操作

修改网卡配置文件

创建bond0配置文件

[root@RAC1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-bond0

写入

DEVICE=bond0

BOOTPROTO=none

IPADDR=10.5.10.2

NETMASK=255.255.255.0

ONBOOT=yes

TYPE=Ethernet

GATEWAY=10.5.10.254

USERCTL=no

IPV6INIT=no

PEERDNS=yes

创建bond1配置文件

[root@RAC1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-bond1

写入

DEVICE=bond1

BOOTPROTO=none

IPADDR=8.8.8.1

NETMASK=255.0.0.0

ONBOOT=yes

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

修改eth0

[root@RAC1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
PEERDNS=yes
MASTER=bond0
SLAVE=yes

修改eth1

[root@RAC1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
PEERDNS=yes
MASTER=bond0
SLAVE=yes

修改eth2

[root@RAC1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth2
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
PEERDNS=yes
MASTER=bond1
SLAVE=yes

修改eth3

[root@RAC1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-eth3

DEVICE=eth3
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
PEERDNS=yes
MASTER=bond1
SLAVE=yes

配置绑定模型

[root@RAC1 ~]# vi /etc/modprobe.d/dist.conf

添加

alias bond0 bonding
options bond0 miimon=100 mode=0

alias bond1 bonding
options bond1 miimon=100 mode=0

mode 的值表示工作模式，0代表负载，1代表冗余

配置网卡启动顺序

[root@RAC1 ~]# vi /etc/rc.d/rc.local 

添加

ifenslave bond0 eth0 eth1

ifenslave bond1 eth2 eth3

关闭NetworkManager 服务

[root@RAC1 ~]# service NetworkManager stop
[root@RAC1 ~]# chkconfig NetworkManager off

重启网络服务

[root@RAC1 ~]# chkconfig NetworkManager off
[root@RAC1 ~]# service network restart
正在关闭接口 bond0： [确定]
正在关闭接口 bond1： [确定]
关闭环回接口： [确定]
弹出环回接口： [确定]
弹出界面 bond0： Determining if ip address 10.5.10.2 is already in use for device bond0...
[确定]
弹出界面 bond1： Determining if ip address 8.8.8.1 is already in use for device bond1...
[确定]

RAC1的网卡绑定操作完成

RAC2操作

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

五、重启RAC1与RAC2

六、修改VIP

[root@RAC1 ~]# cd /u01/app/11.2.0/grid/bin/
[root@RAC1 bin]# srvctl modify nodeapps -n rac1 -A 10.5.10.4/255.255.255.0/bond0
[root@RAC1 bin]# srvctl modify nodeapps -n rac2 -A 10.5.10.5/255.255.255.0/bond0

七、启动RAC

[root@RAC1 bin]# crsctl start crs
CRS-4640: Oracle High Availability Services is already active
CRS-4000: Command Start failed, or completed with errors.

RAC已经启动

[root@RAC1 bin]# crs_stat -t
