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 172.18.4.0 global public
2) 利用oifcfg命令,进行删除,修改public ip
[grid@rac1 ~]$ oifcfg delif -global eth0/172.18.4.0 [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
3) OS修改/etc/hosts, ifcfg-eth0文件(On all node)
# vi /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 # PUBLIC 192.168.56.10 rac1 192.168.56.20 rac2 -------------------------------------------------- # vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes HWADDR=08:00:27:2e:0e:4e IPADDR=192.168.56.10 NETMASK=255.255.255.0 -------------------------------------------------- 重启网络服务 # service network restart
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/192.168.56.30/255.255.255.0/eth0 VIP exists.:rac2 VIP exists.: /rac2vip/192.168.56.40/255.255.255.0/eth0
3) 修改/etc/hosts文件中的 vip
#VIP 192.168.56.30 rac1vip 192.168.56.40 rac2vip
4) 使用root用户修改vip资源
[grid@rac1 ~]$ srvctl modify nodeapps -n rac1 -A 192.168.56.30/255.255.255.0/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 192.168.56.30/255.255.255.0/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
修改SCAN IP
1) 以grid用户停止资源[grid@rac1 ~]$ srvctl stop scan_listener [grid@rac1 ~]$ srvctl stop scan
2) 修改/etc/hosts文件中的SCAN IP
#SCAN IP 192.168.56.50 scanip
3) 以root用户更改SCAN IP
[grid@rac1 ~]$ su root Password: [root@rac1 grid]# srvctl modify scan -n scanip
4) 以grid用户更改及启动资源
[grid@rac1 ~]$ srvctl modify scan_listener -u [grid@rac1 ~]$ srvctl start scan_listener
5) 确认更改
[grid@rac1 ~]$ srvctl config scan SCAN name: scanip, Network: 1/192.168.56.0/255.255.255.0/eth0 SCAN VIP name: scan1, IP: /scanip/192.168.56.50 [grid@rac1 ~]$ srvctl config scan_listener SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
修改Private IP
'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.bak
1) 确保集群中所有节点都已经启动并正常运行
2) 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 192.168.56.0 global public
3) 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 192.168.56.0 global public
eth1 20.20.20.0 global cluster_interconnect
4) 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.
5) 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 # vi /etc/sysconfig/network-scripts/ifcfg-eth1 # Intel Corporation 82540EM Gigabit Ethernet Controller DEVICE=eth1 BOOTPROTO=none ONBOOT=yes HWADDR=08:00:27:b1:33:73 IPADDR=20.20.20.10 NETMASK=255.255.255.0 重启网络服务 # service network restart 确保能相互ping 通 [root@rac1 ~]# ping rac1priv [root@rac1 ~]# ping rac2priv
6) 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.
7) 删除旧的private ip
[grid@rac2 ~]$ oifcfg delif -global eth1/10.10.10.0 [grid@rac2 ~]$ oifcfg getif eth0 192.168.56.0 global public eth1 20.20.20.0 global cluster_interconnect
