Instance orcl1 is running on node db1
Instance orcl2 is running on node db2
[grid@db1 ~]$ srvctl stop database -d orcl
[grid@db1 ~]$ srvctl status database -d orcl
Instance orcl1 is not running on node db1
Instance orcl2 is not running on node db2
2 查看原scan的信息[grid@db1 ~]$ srvctl config scan
SCAN name: scanip, Network: 1/192.168.11.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /scanip/192.168.11.101
[grid@db1 ~]$ srvctl config listener

End points: TCP:15213 关闭listener、crs[grid@db1 ~]$ srvctl stop listener
[grid@db1 ~]$ crsctl stop crs -f

[root@db1 grid]# crsctl stop crs -f[root@db2 grid]# crsctl stop crs -f4 修改/etc/hosts（两个节点）[root@db1 ~]# vi /etc/hosts
#####PUBLIC IP #####
192.168.57.100 db1
192.168.57.200 db25 修改os网卡信息（两个节点）vi /etc/sysconfig/network-scripts/ifcfg-eth0service network restart然后在虚拟机上重新配置网卡连接方式，（在宿主机上新建立一个虚拟网卡虚拟机桥接在该网卡上）6 启动crs（两个节点）[root@db1 grid]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.[root@db2 grid]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.–节点1
1 查看信息（原）
[root@db1 grid]# oifcfg getif
eth2 10.0.0.0 global cluster_interconnect
eth0 192.168.11.0 global public2 删除原ip
[root@db1 grid]# oifcfg delif -global eth0/192.168.11.03 注册新ip
[root@db1 grid]# oifcfg setif -global eth0/192.168.57.0:public4 验证
[root@db1 grid]# oifcfg getif
eth2 10.0.0.0 global cluster_interconnect
eth0 192.168.57.0 global public–节点2[root@db2 grid]# oifcfg getif
eth2 10.0.0.0 global cluster_interconnect
eth0 192.168.57.0 global public –网段已经改过来了。我感觉已经不用删除，再添加了[root@db2 grid]# oifcfg delif -global eth0/192.168.11.0
[root@db2 grid]# oifcfg setif -global eth0/192.168.57.0:public
[root@db2 grid]# oifcfg getif
eth2 10.0.0.0 global cluster_interconnect
eth0 192.168.57.0 global public1 查看vip配置[root@db2 admin]# srvctl config nodeapps -a
Network exists: 1/192.168.11.0/255.255.255.0/eth0, type static

VIP exists: /db2_vip/192.168.11.222/192.168.11.0/255.255.255.0/eth0, hosting node db22 停实例和vip[root@db1 grid]# srvctl stop instance -d rac -n db1
[root@db1 grid]# srvctl stop vip -n db1 -f

[root@db2 grid]# srvctl stop instance -d rac -n db2
[root@db2 grid]# srvctl stop vip -n db2 -f3
修改hosts文件（root两个节点）vi /etc/hosts##### VIP #####192.168.57.111 db1_vip192.168.57.222 db2_vip4 修改vip的配置–节点1
[root@db1 grid]# /grid/11.2.0/grid/bin/srvctl modify nodeapps -n db2 -A 192.168.57.111/255.255.255.0/eth0–节点2
[root@db2 grid]# /grid/11.2.0/grid/bin/srvctl modify nodeapps -n db2 -A 192.168.57.222/255.255.255.0/eth05 启动–节点1[root@db1 grid]# srvctl start vip -n db1
PRKO-2420 : VIP is already started on node(s): db1
[root@db1 grid]# srvctl start listener -n db1
[root@db1 grid]# srvctl start instance -d rac -n db1–节点2[root@db2 grid]# srvctl start vip -n db2
[root@db2 grid]# srvctl start listener -n db2
[root@db2 grid]# srvctl start instance -d rac -n db26 验证[root@db2 grid]# srvctl config nodeapps -a
Network exists: 1/192.168.57.0/255.255.255.0/eth0, type static
VIP exists: /db1_vip/192.168.57.111/192.168.57.0/255.255.255.0/eth0, hosting node db1

1停止scan服务和scan[root@db1 grid]# srvctl stop sca免费主机域名n_listener
[root@db1 grid]# srvctl stop scan

2 修改host文件vi /etc/hosts#####SCAN IP #####192.168.57.101 scanip3修改scan配置（root）

[root@db1 grid]# srvctl modify scan -n scanip
–这里是自己hosts解析的scanip的名字
4 修改scan listener配置
[root@db1 grid]# srvctl modify scan_listener -u5 启动
[root@db1 grid]# srvctl start scan_listener6 启动数据库
[root@db1 grid]# srvctl start database -d orcl7 验证
[root@db1 grid]# srvctl config scan
SCAN name: scanip, Network: 1/192.168.57.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /scanip/192.168.57.101–查看集群资源[root@db1 grid]# crsctl stat res -t

知识补充：–添加scan[root@db1 grid]# srvctl add scan scanip–添加实例$ srvctl add instance -d orcl -i orcl1 -n db1$ srvctl add instance -d orcl -i orcl2 -n db2srvctl start instance -d orcl -n db1srvctl start instance -d orcl -n db2

–添加database
srvctl add database -d orcl -o /oracle/home -p +DATA/orcl/spfileorcl.orasrvctl start database -d orcl–添加本地监听srvctl add listener -l listenercrsctl start resource ora.LISTENER.lsnr–添加scan资源srvctl add scan -n scanipsrvctl start scan到此，相信大家对“怎么修改linux中rac上IP地址”有了更深的了解，不妨来实际操作一番吧！这里是云技术网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习！
