一点一滴努力,满仓满谷收成

1 修改scan-ip

1)查看scan ip的状态信息

[grid@rac1 ~]$ srvctl config scan
SCAN name: rac-cluster-scan, Network: 1/192.168.10.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac-cluster-scan/192.168.10.130

2)停止scan_listener,scan 应用

[grid@rac1 ~]$ srvctl stop scan_listener
[grid@rac1 ~]$ srvctl stop scan

3)在所有节点中 /etc/hosts 文件中修改 scan 对应的ip

[root@rac1 ~] vi /etc/hosts
[root@rac2 ~] vi /etc/hosts

4)使用root命令修改scan-ip，即修改为/etc/hosts里面scan-ip对应的ip

[root@rac1 ~]# cd /u01/app/11.2.0/grid/bin
[root@rac1 bin]# ./srvctl modify scan -n scanip

注：-n后面跟的是/etc/hosts下scan的名称

5)以grid用户更改及启动资源

[grid@rac1 ~]$ srvctl modify scan_listener -u
[grid@rac1 ~]$ srvctl start scan_listener

6)测试和查看

[grid@rac1 ~]$ ping 192.168.10.146

[grid@rac1 ~]$ srvctl config scan
SCAN name: rac-cluster-scan, Network: 1/192.168.10.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac-cluster-scan/192.168.10.146

[grid@rac1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

2 修改Public Ip
1) 查看当前集群 Ip信息

[grid@rac1 ~]$ su root
Password:
[root@rac1 grid]# oifcfg getif
eth1  10.10.10.0  global  cluster_interconnect
eth0  172.18.56.0  global  public

2）所有结点修改物理ip

3) 利用oifcfg命令，进行删除，修改public ip

[grid@rac1 ~]$ oifcfg delif -global eth0/172.18.56.0
[grid@rac1 ~]$ oifcfg setif -global eth0/192.168.56.0:public
[grid@rac1 ~]$ oifcfg getif
eth1  10.10.10.0  global  cluster_interconnect
eth0  192.168.56.0  global  public

4) OS修改/etc/hosts, ifcfg-eth0文件（On all node）

# vi /etc/hosts
# PUBLIC
192.168.10.147  rac1
192.168.10.148  rac2

3 修改vip

1) 停止节点1的实例和vip资源

[grid@rac1 ~]$ srvctl stop instance -d orcl -n rac1
[grid@rac1 ~]$ srvctl stop vip -n rac1 -f

2) 查看原始vip资源配置

[grid@rac1 ~]$ srvctl config nodeapps -a
VIP exists.:rac1
VIP exists.: /rac1vip/192.168.10.149/255.255.255.0/eth0
VIP exists.:rac2
VIP exists.: /rac2vip/192.168.10.150/255.255.255.0/eth0

3) 修改/etc/hosts文件中的 vip

#VIP
192.168.10.149 rac1vip
192.168.10.150 rac2vip

4) 使用root用户修改vip资源

[grid@rac1 ~]$ srvctl modify nodeapps -n rac1 -A 192.168.10.149/255.255.255.0/eth0
PRCN-2018 : Current user grid is not a privileged user
[grid@rac1 ~]$ su root
Password:
[root@rac1 grid]# srvctl modify nodeapps -n rac1 -A 192.168.10.149/255.255.255.0/eth0

5) 启动服务

[grid@rac1 ~]$ srvctl start vip -n rac1
[grid@rac1 ~]$ srvctl start listener -n rac1
[grid@rac1 ~]$ srvctl start instance -d orcl -n rac1

6) 集群其他节点请重复以上1-5的动作

4 修改Private IP

1)备份
在对集群中所有节点操作之前，请先备份 profile.xml 配置文件。作为 grid 用户执行’：

[grid@rac1 ~]$ cd /u01/11.2.0/grid/gpnp/rac1/profiles/peer/
[grid@rac1 peer]$ cp -p profile.xml profile.xml.bak123

2) 确保集群中所有节点都已经启动并正常运行
3) 使用grid用户，获取以下信息，例如：

[grid@rac1 peer]$ oifcfg getif
eth1  10.10.10.0  global  cluster_interconnect
eth0  192.168.10.0  global  public123

4) 加入新的private ip

[grid@rac1 peer]$ oifcfg setif -global eth1/20.20.20.0:cluster_interconnect

[grid@rac1 peer]$ oifcfg getif
eth1  10.10.10.0  global  cluster_interconnect
eth0  192.168.10.0  global  public
eth1  20.20.20.0  global  cluster_interconnect

5) 使用root用户关闭集群中所有节点并禁用集群（每个节点）

[grid@rac1 peer]$ su - root
Password: 
[root@rac1 peer]# crsctl stop crs
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'rac1'
CRS-2673: Attempting to stop 'ora.crsd' on 'rac1'
CRS-2790: Starting shutdown of Cluster Ready Services-managed resources on 'rac1'
CRS-2673: Attempting to stop 'ora.CRSDG.dg' on 'rac1'
CRS-2677: Stop of 'ora.LISTENER_SCAN1.lsnr' on 'rac1' succeeded
CRS-2673: Attempting to stop 'ora.scan1.vip' on 'rac1'
CRS-2677: Stop of 'ora.LISTENER.lsnr' on 'rac1' succeeded
…
CRS-4133: Oracle High Availability Services has been stopped.
[root@rac1 peer]# crsctl disable crs
CRS-4621: Oracle High Availability Services autostart is disabled.

6) 更改/etc/hosts,ifcfg-eth1文件（两个节点）

# vi /etc/hosts
# PRIVATE               
20.20.20.10  rac1priv  
20.20.20.20  rac2priv

修改物理IP
确保能相互ping 通

[root@rac1 ~]# ping rac1priv
[root@rac1 ~]# ping rac2priv

7) 使用root用户激活集群并重新启动集群中所有节点（每个节点）

[grid@rac1 ~]$ su root
Password: 
[root@rac1 grid]# crsctl enable crs
CRS-4622: Oracle High Availability Services autostart is enabled.
[root@rac1 grid]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.

8) 删除旧的private ip

[grid@rac2 ~]$ oifcfg delif -global eth1/10.10.10.0
[grid@rac2 ~]$ oifcfg getif
eth0  192.168.10.0  global  public
eth1  20.20.20.0  global  cluster_interconnect
