最近好久没写文章了~，周一可能会帮同事修改IP地址，所以今天测了下，同时写一篇文章留存记录。本次测试的是修改不同网段的rac ip地址，话不多说，开整！ 修改不同网段公网，私网，vip，scan ip步骤

修改ip地址： 1.查看接口配置并修改： [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg getif enp0s3 192.168.6.0 global public 公网ip网段 enp0s8 10.10.10.0 global cluster_interconnect 私网ip网段 删除原公有，私有IP地址: [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg delif -global enp0s3 [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg delif -global enp0s8 重新设置新Public IP： [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg setif -global enp0s3/192.168.60.0:public [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg setif -global enp0s8/10.10.20.0:cluster_inerconnect [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg getif

2.停止has服务： /oracle/app/11.2.0/grid/bin/crsctl stop has

3.通过操作系统命令修改公有，私有IP地址 linux： vi /etc/sysconfig/network-scripts/ifcfg-enp0s3 systemctl restart network 修改SCAN域名配置（存在DNS域名方式解析，修改域名映射） 修改hosts文件公共IP地址,VIP地址,SCAN地址 vi /etc/hosts

4.启动has： /oracle/app/11.2.0/grid/bin/crsctl start has

5.查看和修改网络资源 /oracle/app/11.2.0/grid/bin/srvctl config network Network exists: 1/192.168.6.0/255.255.255.0/enp0s3, type static

/oracle/app/11.2.0/grid/bin/srvctl modify network -k 1 -S 192.168.60.0/255.255.255.0/enp0s3 -v

6.重新配置SCAN VIP和SCAN Listener [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config scan SCAN name: rac-scan, Network: 1/192.168.6.0/255.255.255.0/enp0s3 SCAN VIP name: scan1, IP: /rac-scan/192.168.6.254

[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config scan_listener SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl stop scan_listener [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl stop scan [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl remove scan_listener [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl remove scan

[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl add scan -n scan(新的scan名称) -k 1 -S 192.168.60.0/255.255.255.0/enp0s3 [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl add scan_listener [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl start scan [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl start scan_listener

7.重新配置vip [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config vip -n rac1 [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config vip -n rac2 VIP exists: /rac1-vip/192.168.6.102/192.168.6.0/255.255.255.0/enp0s3, hosting node rac1

[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/crsctl stop resource ora.rac1.vip -f [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/crsctl stop resource ora.rac2.vip -f

[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl modify nodeapps -A 192.168.60.101/255.255.255.0/enp0s3 -n rac1 [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl modify nodeapps -A 192.168.60.201/255.255.255.0/enp0s3 -n rac2

[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/crsctl start resource ora.rac1.vip -f [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/crsctl start resource ora.rac2.vip -f

ps：–crsctl eval stop resource ora.cdbrac.db -unsupported(划重点12c的变化，eval是模拟命令)Doc ID 1966448.1

8.启动本地监听 [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl start listener -n rac1 [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl start listener -n rac2

9.修改数据库实例参数 alter system set local_listener=’(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.60.101)(PORT=1521))))’ scope=both sid=‘prod1’; alter system set local_listener=’(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.60.201)(PORT=1521))))’ scope=both sid=‘prod2’; alter system register;

10.检查资源状态 ifconfig [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config scan [root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config scan_listener grid $lsnrctlstatusgrid$lsnrctl status listener_scan1 grid$crsctl status res –t 完活了！更多日常运维好文敬请访问： https://www.modb.pro/u/3495?cyn
