一斤蔓、修改root用戶環(huán)境變量
[root@RAC1 ~]# vi .bash_profile
添加如下語句
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
運(yùn)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
目前兩個(gè)節(jié)點(diǎn)的eth0 對應(yīng)Public IP的圆，eth1 對應(yīng)Private IP，目標(biāo)是eth0 與eht1 綁定bond0對應(yīng)Public IP尿背，eth3 與eth4 綁定bond1對應(yīng)Private IP,具體IP地址不變弟疆。
三、修改RAC配置
一旦修改網(wǎng)卡綁定之后批钠，RAC就不能啟動宇植，也就不能進(jìn)行修改，所以我們這里先修改PUBLIC和 Private配置埋心。修改完之后再綁定雙網(wǎng)卡当纱。
當(dāng)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
網(wǎng)絡(luò)存在: 1/10.5.10.0/255.255.255.0/eth0, 類型 static
VIP 存在: /10.5.10.4/10.5.10.4/10.5.10.0/255.255.255.0/eth0, 托管節(jié)點(diǎn) rac1
VIP 存在: /10.5.10.5/10.5.10.5/10.5.10.0/255.255.255.0/eth0, 托管節(jié)點(diǎn) rac2
GSD 已存在
ONS 存在: 本地端口 6100, 遠(yuǎn)程端口 6200, EM 端口 2016
[root@RAC1 bin]# srvctl config nodeapps -n rac1 -a
-n <node_name> 選項(xiàng)已過時(shí)。
網(wǎng)絡(luò)存在: 1/10.5.10.0/255.255.255.0/eth0, 類型 static

[root@RAC1 bin]# srvctl config nodeapps -n rac2 -a
-n <node_name> 選項(xiàng)已過時(shí)踩窖。
網(wǎng)絡(luò)存在: 1/10.5.10.0/255.255.255.0/eth0, 類型 static
VIP 存在: /10.5.10.5/10.5.10.5/10.5.10.0/255.255.255.0/eth0, 托管節(jié)點(diǎn) rac2
修改Public和 Private信息
刪除當(dāng)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
目前無法刪除Private 信息，需要先添加再刪除
[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
四晨横、雙網(wǎng)卡綁定配置
停止RAC
[root@RAC1 bin]# crsctl stop crs
RAC1操作
修改網(wǎng)卡配置文件
創(chuàng)建bond0配置文件
[root@RAC1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-bond0
寫入
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
創(chuàng)建bond1配置文件
[root@RAC1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-bond1
寫入
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
配置綁定模型
[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 的值表示工作模式洋腮，0代表負(fù)載，1代表冗余
配置網(wǎng)卡啟動順序
[root@RAC1 ~]# vi /etc/rc.d/rc.local
添加
ifenslave bond0 eth0 eth1
ifenslave bond1 eth2 eth3
關(guān)閉NetworkManager 服務(wù)
[root@RAC1 ~]# service NetworkManager stop
[root@RAC1 ~]# chkconfig NetworkManager off
重啟網(wǎng)絡(luò)服務(wù)
[root@RAC1 ~]# chkconfig NetworkManager off
[root@RAC1 ~]# service network restart
正在關(guān)閉接口 bond0： [確定]
正在關(guān)閉接口 bond1： [確定]
關(guān)閉環(huán)回接口： [確定]
彈出環(huán)回接口： [確定]
彈出界面 bond0： Determining if ip address 10.5.10.2 is already in use for device bond0...
[確定]
彈出界面 bond1： Determining if ip address 8.8.8.1 is already in use for device bond1...
[確定]
RAC1的網(wǎng)卡綁定操作完成
RAC2操作
RAC2的網(wǎng)卡綁定操作步驟與RAC1相同手形，注意修改對應(yīng)的bond0與bond1的IP地址即可啥供。
五、重啟RAC1與RAC2
六库糠、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
七伙狐、啟動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已經(jīng)啟動
[root@RAC1 bin]# crs_stat -t
Name Type Target State Host
