oracle 10g rac modify public ip,private ip,vip实验步骤
1 实验目的
根据业务的需求，有时需要调整IP,以下为做实验调整前后对应的IP表
调整前对应ip表
主机名 类型 IP 地址 网卡端口
p595a2 public ip 1.4.128.88 en0
p595a2-vip vip 1.4.128.89 en0
p595a2-priv private ip 192.168.4.100 en3
p595b2 public ip 1.4.128.90 en0
p595b2-vip vip 1.4.128.91 en0
p595b2-priv private ip 192.168.4.101 en3
调整后对应ip表
主机名 类型 IP 地址 网卡端口
p595a2 public ip 200.200.200.1 en0
p595a2-vi vip 200.200.200.2 en0
p595a2-priv private ip 192.168.5.100 en3
p595b2 public ip 200.200.200.3 en0
p595b2-vip vip 200.200.200.4 en0
p595b2-priv private ip 192.168.5.101 en3
2 实验一修改public ip与private ip
2.1两边节点 停止数据库，监听，asm,gsd,vip,ons服务
oracle用户
srvctl stop database -d fsyyk -o immediate
srvctl stop asm -n p595a2
srvctl stop asm -n p595b2
srvctl stop nodeapps -n p595a2
srvctl stop nodeapps -n p595b2
root用户
./crsctl stop crs
2.2 修改两边节点的/etc/hosts文件
修改前先做个备份
cp /etc/hosts /etc/hosts.bak
修改后如下所示:
200.200.200.1 p595a2
200.200.200.2 p595a2-vip
192.168.5.100 p595a2-priv
200.200.200.3 p595b2
200.200.200.4 p595b2-vip
192.168.5.101 p595b2-priv
2.3 修改p595a节点上的public ip与private ip
2.3.1 用smitty命令修改物理ip
smitty tcpip
修改public ip
选择en0
修改ip为 200.200.200.1，网关为200.200.200.254
修改private ip
选择en3
修改ip为 192.168.5.100
注意检查修改hosts文件，因为改ip后，hosts文件会增加记录。
2.3.2 用oifcfg命令修改ip更新ocr盘
root用户启动crs
./crsctl start crs
oracle用户
先查看
oifcfg getif
en0 1.4.128.0 global public
en3 192.168.4.0 global cluster_interconnect
修改
oifcfg delif -global en0
oifcfg setif -global en0/200.200.200.0:public
oifcfg delif -global en3
oifcfg setif -global en3/192.168.5.0:cluster_interconnect
确认
oifcfg getif
en0 200.200.200.0 global public
en3 192.168.5.0 global cluster_interconnect
2.4 修改p595b节点上的public ip与private ip
2.4.1 用smitty命令修改物理ip
smitty tcpip
修改public ip
选择en0
修改ip为 200.200.200.3，网关为200.200.200.254
修改private ip
选择en3
修改ip为 192.168.5.101
注意检查修改hosts文件，因为改ip后，hosts文件会增加记录。
2.4.2 启动crs
root用户启动crs
cd /crs/app/oracle/product/crs_1/bin
./crsctl start crs
2.4.3 用oifcfg命令检查ocr盘中ip信息
oracle用户
oifcfg getif
en0 200.200.200.0 global public
en3 192.168.5.0 global cluster_interconnect
注意这边不需要修改,只是确认。
2.5 修改listener.ora与tnsnames.ora文件
cd $ORACLE_HOME/network/admin
涉及到有public ip的地方都要修改
2.6 验证两边节点服务状态是否正常
crs_stat –t
[oracle@p595a2:/oracle/app/oracle]$crs_stat -t
Name Type Target State Host

3 实验二修改vip
3.1 停止数据库，监听，asm,gsd,vip,ons服务
oracle用户下运行以下命令
srvctl stop database -d fsyyk -o immediate
srvctl stop asm -n p595a2
srvctl stop asm -n p595b2
srvctl stop nodeapps -n p595a2
srvctl stop nodeapps -n p595b2
3.2 用srvctl config nodeapps 检查vip设置
oracle用户
srvctl config nodeapps -n p595a2 -a
VIP exists.: /p595a2-vip/1.4.128.89/255.255.255.0/en0
srvctl config nodeapps -n p595b2 -a
VIP exists.: /p595a2-vip/1.4.128.91/255.255.255.0/en0
3.3 用srvctl modify nodeapps 修改vip地址
oracle用户
srvctl modify nodeapps -n p595a2 -A 200.200.200.2/255.255.255.0/en0
srvctl modify nodeapps -n p595b2 -A 200.200.200.4/255.255.255.0/en0
确认
srvctl config nodeapps -n p595a2 -a
VIP exists.: /p595a2-vip/200.200.200.2/255.255.255.0/en0
srvctl config nodeapps -n p595b2 -a
VIP exists.: /p595a2-vip/200.200.200.4/255.255.255.0/en0
3.4 修改listener.ora与tnsnames.ora文件
cd $ORACLE_HOME/network/admin
涉及到有vip的地方都要修改
3.5 启动数据库，监听，asm,gsd,vip,ons服务
oracle用户
srvctl start nodeapps -n p595a2
srvctl start nodeapps -n p595b2
srvctl start asm -n p595a2
srvctl start asm -n p595b2
srvctl start database -d fsyyk
3.6 验证两边节点服务状态是否正常
crs_stat –t
[oracle@p595a2:/oracle/app/oracle]$crs_stat -t
Name Type Target State Host
------------------------------------------------------------

4 实验总结
1. 在修改public ip时注意修改对应的网关，如果不修改，有可能导致vip服务起不来。
