主要实施步骤如下：
环境说明：服务器操作系统centos7.3、oracle RAC 11.2.0.4
说明：服务器实际ip变动，虚拟ip不变
#pub 80.150.20.101 msrkzyk1 80.150.20.102 msrkzyk2 #pri 172.168.1.1 msrkzyk1p 172.168.1.2 msrkzyk2p #vip 80.150.20.103 msrkzyk1v 80.150.20.104 msrkzyk2v #scan 80.150.20.105 msrkscan ----- --改后 #pub 80.150.22.101 msrkzyk1 80.150.22.102 msrkzyk2 #pri 172.168.1.1 msrkzyk1p 172.168.1.2 msrkzyk2p #vip 80.150.22.103 msrkzyk1v 80.150.22.104 msrkzyk2v #scan 80.150.22.105 msrkscan
1、[root@node-1 ~]# crs_stop -all
[root@node-1 ~]# crsctl stop crs -f #强制停止
2、修改服务器的物理ip
3、然后再vi修改/etc/hosts文件
4、重新配置免密ssh
su - grid ssh-keygen ssh-copy-id grid@80.150.22.101 ssh-copy-id grid@80.150.22.102 ssh-copy-id grid@172.168.1.1 ssh-copy-id grid@172.168.1.2 ssh grid@172.168.1.1 date ssh grid@172.168.1.2 date ssh grid@80.150.22.101 date ssh grid@80.150.22.102 date ssh grid@msrkzyk1 date ssh grid@msrkzyk2 date ssh grid@msrkzyk1p date ssh grid@msrkzyk2p date su - oracle ssh-keygen ssh-copy-id oracle@80.150.22.101 ssh-copy-id oracle@80.150.22.102 ssh-copy-id oracle@172.168.1.1 ssh-copy-id oracle@172.168.1.2 ssh oracle@172.168.1.1 date ssh oracle@172.168.1.2 date ssh oracle@80.150.22.101 date ssh oracle@80.150.22.102 date ssh oracle@msrkzyk1 date ssh oracle@msrkzyk2 date ssh oracle@msrkzyk1p date ssh oracle@msrkzyk2p date
5、启动crs
[root@msrkzyk2 ~]# /u01/grid/11.2/bin/crsctl start crs
注意：这里如果是按照我上面关闭crs的操作，正常数据库和监听是没有启动的，对应target和state都应该是offline：
ora.LISTENER.lsnr
OFFLINE OFFLINE msrkzyk1
OFFLINE OFFLINE msrkzyk2
ora.msrkzyk.db
1 OFFLINE OFFLINE Instance Shutdown
2 OFFLINE OFFLINE Instance Shutdown
6、修改Public IP,VIP,SCAN VIP
6.1 修改Public IP
[root@msrkzyk1 ~]# find / -name oifcfg #查找命令 /u01/grid/11.2/bin/oifcfg getif [root@msrkzyk1 ~]# /u01/grid/11.2/bin/oifcfg getif #查看ip eno1 80.150.20.0 global public eno2 172.168.1.0 global cluster_interconnect #节点一设置ip,删除ip 设置ip [root@msrkzyk1 ~]# /u01/grid/11.2/bin/oifcfg delif -global eno1 #删除原public ip [root@msrkzyk1 ~]# /u01/grid/11.2/bin/oifcfg setif -global eno1/80.150.22.0:public #设置新public ip #两个节点查看ip [root@msrkzyk1 ~]# /u01/grid/11.2/bin/oifcfg getif eno2 172.168.1.0 global cluster_interconnect eno1 80.150.22.0 global public [root@msrkzyk2 ~]# /u01/grid/11.2/bin/oifcfg getif eno2 172.168.1.0 global cluster_interconnect eno1 80.150.22.0 global public
6.2 修改VIP
需要停止数据库、监听和vip，目前数据库和监听、vip都是停止的查看命令grid用户
srvctl stop vip -n msrkzyk1 #停止命令
#单独查看
[grid@msrkzyk1 ~]$ srvctl status vip -n msrkzyk1 VIP msrkzyk1v is enabled VIP msrkzyk1v is not running [grid@msrkzyk1 ~]$ srvctl status vip -n msrkzyk2 VIP msrkzyk2v is enabled VIP msrkzyk2v is not running [grid@msrkzyk1 ~]$ srvctl status database -d msrkzyk Instance msrkzyk1 is not running on node msrkzyk1 Instance msrkzyk2 is not running on node msrkzyk2 [grid@msrkzyk1 ~]$ srvctl status LISTENER -n msrkzyk1 Listener LISTENER is enabled on node(s): msrkzyk1 Listener LISTENER is not running on node(s): msrkzyk1 [grid@msrkzyk1 ~]$ srvctl status LISTENER -n msrkzyk2 Listener LISTENER is enabled on node(s): msrkzyk2 Listener LISTENER is not running on node(s): msrkzyk2
#或者
[grid@msrkzyk1 ~]$ crsctl stat res -t

查看当前vip设置 grid用户
[grid@msrkzyk1 ~]$ olsnodes -s msrkzyk1 Active msrkzyk2 Active [grid@msrkzyk1 ~]$ srvctl config vip -n msrkzyk1 VIP exists: /msrkzyk1v/80.150.22.103/80.150.20.0/255.255.255.0/eno1, hosting node msrkzyk1 [grid@msrkzyk1 ~]$ srvctl config vip -n msrkzyk2 VIP exists: /msrkzyk2v/80.150.22.104/80.150.20.0/255.255.255.0/eno1, hosting node msrkzyk2
修改vip设置 root 用户
[root@msrkzyk1 ~]# find / -name srvctl /u01/grid/11.2/bin/srvctl [root@msrkzyk1 ~]# /u01/grid/11.2/bin/srvctl modify nodeapps -n msrkzyk1 -A 80.150.22.103/255.255.255.0/eno1 [root@msrkzyk1 ~]# /u01/grid/11.2/bin/srvctl modify nodeapps -n msrkzyk2 -A 80.150.22.104/255.255.255.0/eno1
再次验证vip设置
[root@msrkzyk1 ~]# /u01/grid/11.2/bin/srvctl config vip -n msrkzyk1 VIP exists: /msrkzyk1v/80.150.22.103/80.150.22.0/255.255.255.0/eno1, hosting node msrkzyk1 [root@msrkzyk1 ~]# /u01/grid/11.2/bin/srvctl config vip -n msrkzyk2 VIP exists: /msrkzyk2v/80.150.22.104/80.150.22.0/255.255.255.0/eno1, hosting node msrkzyk2
启动vip、grid用户
[root@msrkzyk1 ~]# su - grid Last login: Tue Sep 7 14:52:57 CST 2021 on pts/1 [grid@msrkzyk1 ~]$ srvctl start vip -n msrkzyk1 [grid@msrkzyk1 ~]$ srvctl start vip -n msrkzyk2 [grid@msrkzyk1 ~]$ srvctl status vip -n msrkzyk1 VIP msrkzyk1v is enabled VIP msrkzyk1v is running on node: msrkzyk1 [grid@msrkzyk1 ~]$ srvctl status vip -n msrkzyk2 VIP msrkzyk2v is enabled VIP msrkzyk2v is running on node: msrkzyk2
启动监听
[grid@msrkzyk1 ~]$ srvctl start listener [grid@msrkzyk1 ~]$ srvctl status LISTENER Listener LISTENER is enabled Listener LISTENER is running on node(s): msrkzyk2,msrkzyk1
启动数据库
[grid@msrkzyk1 ~]$ srvctl start database -d msrkzyk [grid@msrkzyk1 ~]$ srvctl status database -d msrkzyk Instance msrkzyk1 is running on node msrkzyk1 Instance msrkzyk2 is running on node msrkzyk2
4、检查local_listener信息，不正确就需要修改（我这儿对的不用修改）
[oracle@msrkzyk1 ~]$ sqlplus / as sysdba SQL> show parameter local_listener NAME TYPE VALUE -------- --------- ---------------- local_listener string (ADDRESS=(PROTOCOL=TCP)(HOST=80.150.22.103)(PORT=1521)) #修改的命令 alter system set local_listenner='(ADDRESS=(PROTOCOL=TCP)(HOST=80.150.22.103)(PORT=1521))' sid='msrkzyk1'; alter system set local_listenner='(ADDRESS=(PROTOCOL=TCP)(HOST=80.150.22.104)(PORT=1521))' sid='msrkzyk2';
5、修改scan vip
查看scan vip的配置 grid用户
[root@msrkzyk1 ~]# su - grid [grid@msrkzyk1 ~]$ srvctl config scan SCAN name: msrkscan, Network: 1/80.150.22.0/255.255.255.0/eno1 SCAN VIP name: scan1, IP: /msrkscan/80.150.20.105
停止scan_listener和scan资源
[grid@msrkzyk1 ~]$ srvctl stop scan_listener [grid@msrkzyk1 ~]$ srvctl stop scan
--确认已经停止
[grid@msrkzyk1 ~]$ srvctl status scan_listener SCAN Listener LISTENER_SCAN1 is enabled SCAN listener LISTENER_SCAN1 is not running [grid@msrkzyk1 ~]$ srvctl status scan SCAN VIP scan1 is enabled SCAN VIP scan1 is not running
使用root用户修改scan vip
[root@msrkzyk1 ~]# /u01/grid/11.2/bin/srvctl modify scan -n msrkscan
注意：root用户执行修改，且确认/etc/hosts映射关系已经修改为新的scan VIP。
修改并启动资源库 grid用户
[grid@msrkzyk1 ~]$ srvctl modify scan_listener -u [grid@msrkzyk1 ~]$ srvctl start scan_listener
注意：执行后确认scan_listener和scan都已经启动
[grid@msrkzyk1 ~]$ srvctl status scan_listener SCAN Listener LISTENER_SCAN1 is enabled SCAN listener LISTENER_SCAN1 is running on node msrkzyk1 [grid@msrkzyk1 ~]$ srvctl status scan SCAN VIP scan1 is enabled SCAN VIP scan1 is running on node msrkzyk1
确认修改成功
[grid@msrkzyk1 ~]$ srvctl config scan SCAN name: msrkscan, Network: 1/80.150.22.0/255.255.255.0/eno1 SCAN VIP name: scan1, IP: /msrkscan/80.150.22.105 [grid@msrkzyk1 ~]$ srvctl config scan_listener SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
6、验证整个集群
[grid@msrkzyk1 ~]$ crsctl stat res -t
