11gRAC修改scanip，vip，public ip

修改前集群状态:

[grid@rac1 ~]$ crs_stat -t

一、停止数据库和crs及相关资源

[grid@rac1 ~]$ srvctl stop database -d orcl //关闭数据库

[grid@rac1 ~]$ srvctl status database -d orcl //查看数据库状态，orcl为数据库名称

Instance orcl1 is not running on node rac1

Instance orcl2 is not running on node rac2

[grid@rac1~]srvctl disable listener //禁止监听自启动

[grid@rac1 ~]$ srvctl stop listener //关闭监听

[root@rac1~]/u01/app/11.2.0/grid/bin/srvctl disable vip -i "rac1-vip" //禁止各个节点自启动VIP并关闭VIP

[grid@rac1 ~]$ srvctl stop vip -n rac1

[root@rac1~]/u01/app/11.2.0/grid/bin/srvctl disable vip -i "rac2-vip"

[grid@rac1 ~]$ srvctl stop vip -n rac2

[grid@rac1~]$ srvctl disable scan_listener

[grid@rac1 ~]$ srvctl stop scan_listener

[root@rac1 ~]#/u01/app/11.2.0/grid/bin/srvctl disable scan

[grid@rac1 ~]$ srvctl stop scan

[grid@rac2 ~]$ crs_stat -t //查看集群状态

二、将两个节点的crs服务都关闭

[root@rac1 bin]# ./crvctl stop crs //注意：root用户才有权限执行

[root@rac2 bin]# ./crsctl stop crs

或者：

[root@rac1 ~]#/u01/app/11.2.0/grid/bin/crsctl stop crs

[root@rac2 ~]#/u01/app/11.2.0/grid/bin/crsctl stop crs

一定要注意确保crs在所有节点上全部关闭

[root@rac1 bin]# ./crsctl check crs

CRS-4639: Could not contact Oracle High Availability Services

[root@rac1 bin]# ./crsctl check cluster

CRS-4639: Could not contact Oracle High Availability Services

CRS-4000: Command Check failed, or completed with errors.

[root@rac1 bin]# ./crs_stat -t

CRS-0184: Cannot communicate with the CRS daemon.

[root@rac2 bin]# ./crsctl check crs

CRS-4639: Could not contact Oracle High Availability Services

[root@rac2 bin]# ./crsctl check cluster

CRS-4639: Could not contact Oracle High Availability Services

CRS-4000: Command Check failed, or completed with errors.

[root@rac2 bin]# ./crs_stat -t

CRS-0184: Cannot communicate with the CRS daemon.

三、开始修改所有节点的/etc/hosts,注意先不要修改priv

1、vim /etc/hosts

此处有个小插曲：由于我以前使用vi编辑hosts文件没有正确退出导致产生.hosts.swp文件，这样的话就打不开hosts文件了，删除,swp文件后继续执行（[root@rac1 etc]# rm -rf .hosts.swp）。

原IP：

#public IP name

192.168.1.131 rac1

192.168.1.132 rac2

#peivate IP

192.168.26.131 rac1-priv

192.168.26.132 rac2-priv

#vip

192.168.1.211 rac1-vip

192.168.1.212 rac2-vip

#scan

192.168.1.99 scan

修改后：

#public IP name

192.168.1.221 rac1

192.168.1.222 rac2

#peivate IP

192.168.26.135 rac1-priv

192.168.26.136 rac2-priv

#vip

192.168.1.89 rac1-vip

192.168.1.90 rac2-vip

#scan

192.168.1.98 scan

2、修改rac1及rac2网卡配置

注意只是修改public对应的eth0,不修改心跳网卡

注意网关和DNS也需要正确

rac1：vi /etc/sysconfig/network-scripts/ifcfg-eth0 196.168.1.221

rac2：vi /etc/sysconfig/network-scripts/ifcfg-eth0 196.168.1.222

重启网卡,并确保双方的public地址能用hosts直接ping通。

四、 启动crs:

（[root@rac1 ~]#/u01/app/11.2.0/grid/bin/crsctl start  crs

[root@rac2 ~]#/u01/app/11.2.0/grid/bin/crsctl start  crs）

或者：

[root@rac1 bin]# ./crsctl start crs

CRS-4123: Oracle High Availability Services has been started.

[root@rac1 bin]# ./crsctl check crs

CRS-4638: Oracle High Availability Services is online

CRS-4535: Cannot communicate with Cluster Ready Services

CRS-4530: Communications failure contacting Cluster Synchronization Services daemon

CRS-4534: Cannot communicate with Event Manager

（此时的状态为正在连接，需要等待到全部为online状态）

[root@rac2 bin]# ./crsctl start crs

CRS-4123: Oracle High Availability Services has been started.

[root@rac2 bin]# ./crsctl check crs

CRS-4638: Oracle High Availability Services is online

CRS-4535: Cannot communicate with Cluster Ready Services

CRS-4529: Cluster Synchronization Services is online

CRS-4534: Cannot communicate with Event Manager

 集群的public IP 设置（如果属于同一网段，可不修改）----###此步骤未测试

start crs后，请稍等一会儿再执行

[root@rac1bin]# ./oifcfg getif      //查看下集群的VIP

eth0  19.16.0.0 global  public

eth1  5.1.1.0 global  cluster_interconnect

[root@rac1bin]# ./oifcfg delif -global eth0

[root@rac1bin]# ./oifcfg setif -global eth0/19.16.5.0:public

[root@rac1/2bin]# ./oifcfg getif    //两边查看下集群的VIP

这里是举例子，像我这次修改没有更改字段。所以我没有操作这一步。

如果需要修改private ip 则需要先用

[root@rac1bin]# ./oifcfg delif -global eth1

[root@rac1bin]#./oifcfg setif -global eth1/x.x.x.0:cluster_interconnect(注意，我前面修改网卡可没有修改private，private是要在这步先修改后，才可以修改的）  

（以下彩色部分楼主没有测试）

 集群的public IP 设置（如果属于同一网段，可不修改）----###此步骤未测试

start crs后，请稍等一会儿再执行

[root@rac1bin]# ./oifcfg getif      //查看下集群的VIP

eth0  19.16.0.0 global  public

eth1  5.1.1.0 global  cluster_interconnect

[root@rac1bin]# ./oifcfg delif -global eth0

[root@rac1bin]# ./oifcfg setif -global eth0/19.16.5.0:public

[root@rac1/2bin]# ./oifcfg getif    //两边查看下集群的VIP

这里是举例子，像我这次修改没有更改字段。所以我没有操作这一步。

如果需要修改private ip 则需要先用

[root@rac1bin]# ./oifcfg delif -global eth1

[root@rac1bin]#./oifcfg setif -global eth1/x.x.x.0:cluster_interconnect(注意，我前面修改网卡可没有修改private，private是要在这步先修改后，才可以修改的

大成哥的具体步骤：

使用oifcfg修改Public地址:

[grid@rac1 ~]$ oifcfg getif

eth0 192.168.137.0 global public

eth1 192.168.16.0 global cluster_interconnect

看到现在的global public网段值还是原来的,我们要修改成为新的

[grid@rac1 ~]$ oifcfg setif -global eth0/192.168.115.0:public

[grid@rac1 ~]$ oifcfg getif

eth1 192.168.16.0 global cluster_interconnect

eth0 192.168.115.0 global public

注意在一个节点上修改就行了,其他节点会自动同步

[grid@rac2 ~]$ oifcfg getif

eth1 192.168.16.0 global cluster_interconnect

eth0 192.168.115.0 global public

使用srvctl修改vip

[grid@rac1 ~]$ srvctl config vip -n rac1

VIP exists: /rac1-vip/192.168.115.110/192.168.137.0/255.255.255.0/eth0, hosting node rac1

[grid@rac1 ~]$ srvctl config vip -n rac2

VIP exists: /rac2-vip/192.168.115.111/192.168.137.0/255.255.255.0/eth0, hosting node rac2

注意这里的网段还是原来的,需要把网段修改过来:

[grid@rac1 ~]$ srvctl stop vip -n rac1

[grid@rac1 ~]$ srvctl stop vip -n rac2

[root@rac1 bin]# ./srvctl modify nodeapps -n rac1 -A 192.168.115.110/255.255.255.0/eth0

[root@rac1 bin]# ./srvctl modify nodeapps -n rac2 -A 192.168.115.111/255.255.255.0/eth0

五、集群的VIP设置

[root@rac1 bin]# ./srvctl config vip -n rac1 //查看集群VIP

VIP exists: /rac1-vip/192.168.1.89/192.168.1.0/255.255.255.0/eth0, hosting node rac1

[root@rac1 bin]# ./srvctl modify nodeapps -A 192.168.1.89/255.255.255.0/eth0 -n rac1

[root@rac1 bin]# ./srvctl modify nodeapps -A 192.168.1.90/255.255.255.0/eth0 -n rac2

修改VIP资源必须使用srvctl工具手动更新OCR中的VIP配置。如果客户端使用VIP连接数据库，那么还需要修改客户端hosts文件等相关的VIP配置。

[root@rac1 bin]# ./srvctl modify scan -n 192.168.1.98 （注意这里直接写ip的话VIP的name会改变！）

[root@rac1 bin]# ./srvctl enable listener

[root@rac1 bin]# ./srvctl config scan

SCAN name: 192.168.1.98, Network: 1/192.168.1.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /192.168.1.98/192.168.1.98

[root@rac1 bin]# ./srvctl modify scan -n scan（改为scan的名称）

[root@rac1 bin]# ./srvctl config scan

SCAN name: scan, Network: 1/192.168.1.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /scan/192.168.1.98

如果需要修改private   ------#此步骤未测试

(1)rac1：vi /etc/sysconfig/network-scripts/ifcfg-eth0

      修改ip为15.1.1.1掩码255.255.255.0

      service network restart//重启网卡

(2)rac2：vi/etc/sysconfig/network-scripts/ifcfg-eth0

      修改ip为15.1.1.2掩码 255.255.255.0

      service network restart//重启网卡

大成哥的具体步骤：

使用oifcfg修改priv

[root@rac1 bin]# ./oifcfg getif

eth1 192.168.16.0 global cluster_interconnect

eth0 192.168.115.0 global public

[root@rac1 bin]# ./olsnodes -s

rac1 Active

rac2 Active

[root@rac1 bin]# ./oifcfg setif -global eth1/192.168.145.0:cluster_interconnect

[root@rac1 bin]# ./oifcfg getif

eth1 192.168.16.0 global cluster_interconnect

eth0 192.168.115.0 global public

eth1 192.168.145.0 global cluster_interconnect

[root@rac1 bin]# ./oifcfg delif -global eth1/192.168.16.0:cluster_interconnect

[root@rac1 bin]# ./oifcfg getif

eth0 192.168.115.0 global public

eth1 192.168.145.0 global cluster_interconnect

[root@rac2 bin]# ./oifcfg getif

eth0 192.168.115.0 global public

eth1 192.168.145.0 global cluster_interconnect

注意所有节点是不是都配置好了

停止crs

[root@rac1 bin]# ./crsctl stop crs

配置/etc/hosts

配置网卡后重启网卡

配置完之后ping主机名,再次检测hosts文件是否生效

没问题之后重启crsd       [root@rac1 bin]# ./crsctl start crs

六、 启动VIP、监听、scan和scan_listener、数据库

[root@rac1 bin]#./srvctl enable listener      

[root@rac1 bin]#./srvctl enable vip -i "rac1-vip"

[root@rac1 bin]#./srvctl enable vip -i "rac2-vip"

[root@rac1 bin]#./srvctl enable scan_listener

[root@rac1 bin]#./srvctl enable scan

[root@rac1 bin]#./srvctl enable database -d hyw

[root@rac1 bin]#./srvctl start listener      

[root@rac1 bin]#./srvctl start vip -n rac1

[root@rac1 bin]#./srvctl start vip -n rac2

[root@rac1 bin]#./srvctl start scan_listener

[root@rac1 bin]#./srvctl start scan

[root@rac1 bin]#./srvctl start database -d hyw

或者:

[root@rac1 bin]# ./srvctl start listener

[root@rac1 bin]# ./srvctl start vip -n rac1

PRKO-2420 : VIP is already started on node(s): rac1

[root@rac1 bin]# ./srvctl start vip -n rac2

PRKO-2420 : VIP is already started on node(s): rac2

[root@rac1 bin]# ./srvctl start database -d orcl

七、检查VIP资源状态

[root@rac1 bin]# ./srvctl status nodeapps

VIP rac1-vip is enabled                  

VIP rac1-vip is running on node: rac1    

VIP rac2-vip is enabled                  

VIP rac2-vip is running on node: rac2    

Network is enabled                       

Network is running on node: rac1         

Network is running on node: rac2         

GSD is disabled                          

GSD is not running on node: rac1         

GSD is not running on node: rac2         

ONS is enabled                           

ONS daemon is running on node: rac1      

ONS daemon is running on node: rac2    

修改后的各个IP都可以ping同

OK，大功告成！
