变动oracle RAC public ip,vip,scan ip和private ip

?? ??? ?2.3.6修改SCAN VIP
?? ??? ??? ??? ?1.srvctl config scan 查察当前vip配置
?? ??? ??? ??? ??? ?config scan SCAN name: 192.168.128.100,Network: 1/192.168.128.0/255.255.255.0/en0 SCAN VIP name: scan1,IP: /scan-vip/192.168.128.100
?? ??? ??? ??? ?2.用root用户遏制scan_listener 和sacn vip
?? ??? ??? ??? ??? ?$GRID_HOME/bin/srvctl stop scan_listener?
??????????????????? $GRID_HOME/bin/srvctl stop scan?
??????????????????? $GRID_HOME/bin/srvctl status scan
?? ??? ??? ??? ??? ?SCAN VIP scan1 is enabled SCAN VIP scan1 is not running
?? ??? ??? ??? ??? ?$GRID_HOME/bin/srvctl status scan_listener SCAN Listener LISTENER_SCAN1 is enabled SCAN listener LISTENER_SCAN1 is not running
?? ??? ??? ??? ?3.用root用户修改scan vip
?? ??? ??? ??? ??? ?$GRID_HOME/bin/srvctl modify scan -n10.76.31.111
?? ??? ??? ??? ?4.搜查是否修改乐成
?? ??? ??? ??? ??? ?config scan SCAN name: 10.76.31.111,Network: 1/10.76.31.0/255.255.255.0/en0 SCAN VIP name: scan1,IP: /scan-vip/10.76.31.111
?? ??? ??? ??? ?5.启动scan和scan_listener
?? ??? ??? ??? ??? ?$GRID_HOME/bin/srvctl start scan?
??????????????????? $GRID_HOME/bin/srvctl start scan_listener

?? ?3 修改 private ip?? ??? ?3.1 确保crs集群是打开的?? ??? ??? ??? ?可以用olsnodes –s 搜查集群的状态?? ??? ??? ??? ?./olsnodes -s?? ??? ??? ??? ?P570a Active?? ??? ??? ??? ?P570b Active?? ??? ?3.2 用oifcfg getif 搜查和oifcfg setif修改当前private 配置?? ??? ??? ?修改前配置?? ??? ??? ??? ?./oifcfg getif?? ??? ??? ??? ?en0 10.76.31.0 global public?? ??? ??? ??? ?en2 172.168.128.0 global cluster_interconnect?? ??? ??? ?修改private ip,新收集端标语为en8,假如没有修改端标语，则配置的置魅照旧为en2?? ??? ??? ??? ?./oifcfg setif -global en8/192.76.31.0:cluster_interconnect?? ??? ??? ??? ?./oifcfg delif -global en2?? ??? ??? ?修改后配置?? ??? ??? ??? ?./oifcfg getif?? ??? ??? ??? ?en0 10.76.31.0 global public?? ??? ??? ??? ?en8 192.76.31.0 global cluster_interconnect?? ??? ?3.3 双方节点遏制database和crs?? ??? ??? ??? ?./srvctl stop database -d gdcdc -o immedate?? ??? ??? ??? ?./crsctl stop crs?? ??? ??? ??? ?搜查是否封锁?? ??? ??? ??? ?ps -ef|grep grid?? ??? ??? ??? ?ps -ef|grep oracle?? ??? ?3.4 修改双方节点/etc/hosts表?? ??? ??? ??? ?172.168.128.10 p570a-priv?? ??? ??? ??? ?172.168.128.11 p570b-priv?? ??? ??? ??? ?修改为?? ??? ??? ??? ?192.76.31.113 p570a-priv?? ??? ??? ??? ?192.76.31.115 p570b-priv?? ??? ?3.5 修改p570a节点 private ip?? ??? ??? ??? ?用smitty呼吁修改物理私网ip?? ??? ??? ??? ?smitty tcpip?? ??? ??? ??? ?选择en8?? ??? ??? ??? ?修改ip为 192.76.31.113 掩码为 255.255.255.0?? ??? ?3.6 修改P570b节点 private ip?? ??? ??? ??? ?用smitty呼吁修改物理私网ip?? ??? ??? ??? ?smitty tcpip?? ??? ??? ??? ?选择en8?? ??? ??? ??? ?修改ip为 192.76.31.115 掩码为 255.255.255.0?? ??? ?3.7 双方节点启动crs?? ??? ??? ??? ?crsctl start crs?? ??? ??? ??? ?搜查资源组状态?? ??? ??? ??? ?crsctl status resource –t?? ??? ??? ??? ?假如都online，则没题目。?? ?4 实验总结?? ??? ??? ??? ?1. 在修改public ip时留意修改对应的正确网关，假如不修改，有也许导致vip处事起不来。?? ??? ??? ??? ?2. 留意搜查修改hosts文件，由于改ip后，hosts文件会增进记录。?? ??? ??? ??? ??? ??? ?public ip对应的掩码也要修纠正确，?? ??? ??? ??? ?3. 主机名在安装crs时要筹划好，一旦装好后，就不能修改，不然要从头安装crs。?? ??? ??? ??? ?4. 11GR2 srvctl 新增 config vip呼吁?? ??? ??? ??? ?5. 修改private ip的次序恰恰和10gR2相反，10gR2是先封锁crs,然后修改hosts表和物理ip，再启动crs,用oifcfg 配置新私网ip,这点要留意,不然按10gR2修改私网的要领，会导致CRS集群起不来,以是做之前先做好备份。?? ??? ??? ??? ?6. 假如双方节点local_listener参数没修改的话，会导致客户端毗连不到数据库报ERROR:ORA-12516: TNS: 监听措施找不到切合协议仓库要求的可用处理赏罚措施,这是由于scan_listener 认到的照旧修改前的vip原文：https://blog.csdn.net/weixin_34389926/article/details/85139489
