RAC修改public ip,vip,priv_ip,sacn_ip

[grid@rac1 ~]$ oifcfg getif
eth0 192.168.220.0 global public
eth1 192.168.11.0 global cluster_interconnect
[grid@rac1 ~]$ oifcfg iflist
eth0 192.168.220.0
eth1 192.168.11.0
eth1 169.254.0.0
[grid@rac1 ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.220.130 rac1
192.168.220.140 rac2
192.168.220.135 rac1-vip
192.168.220.145 rac2-vip
192.168.11.11 rac1-priv
192.168.11.22 rac2-priv
192.168.220.150 rac-scan

修改后的IP
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.110.11 rac1
192.168.110.22 rac2
192.168.110.111 rac1-vip
192.168.110.222 rac2-vip
10.10.11.30 rac1-priv
10.10.11.40 rac2-priv
192.168.110.50 rac-scan

更改私网IP
----私网IP需要再集群启动的时候进行修改再重启
确认CRS集群在各节点启动：
[root@rac2 grid]# olsnodes -s
rac1 Active
rac2 Active

--查看当前设定：
[root@rac2 grid]# oifcfg getif
eth0 192.168.220.0 global public
eth1 192.168.11.0 global cluster_interconnect

[root@rac1 grid]# oifcfg setif -global eth1/'10.10.11.0':cluster_interconnect
[root@rac1 grid]# oifcfg getif
eth0 192.168.220.0 global public
eth1 192.168.11.0 global cluster_interconnect
eth1 10.10.11.0 global cluster_interconnect

srvctl stop database -d racdb
srvctl stop listener
crsctl stop crs
注意：这样再次启动crs时，就不会自动启动监听和数据库了。

更改网卡IP
vi /etc/sysconfig/network-scripts/ifcfg-eth0
service network restart

启动CRS，可以看到数据库和监听没有启动

-----修改VIP
当前vip已经是停止状态
srvctl stop vip -n rac1
srvctl stop vip -n rac2

[root@rac2 grid]# srvctl config vip -n rac1
VIP exists: /rac1-vip/192.168.110.111/192.168.220.0/255.255.255.0/eth0, hosting node rac1
[root@rac2 grid]# srvctl config vip -n rac2
VIP exists: /rac2-vip/192.168.110.222/192.168.220.0/255.255.255.0/eth0, hosting node rac2

[root@rac1 grid]# srvctl config vip -n rac1
VIP exists: /rac1-vip/192.168.110.111/192.168.110.0/255.255.255.0/eth0, hosting node rac1
[root@rac1 grid]# srvctl config vip -n rac2
VIP exists: /192.168.110.222/192.168.110.222/192.168.110.0/255.255.255.0/eth0, hosting node rac2
[root@rac1 grid]#

srvctl config vip -n rac1
srvctl config vip -n rac2

修改VIP设置：
srvctl modify nodeapps -n rac1 -A 192.168.110.111/255.255.255.0/eth0
srvctl modify nodeapps -n rac2 -A 192.168.110.222/255.255.255.0/eth0

192.168.110.111 rac1-vip
192.168.110.222 rac2-vip

启动vip

srvctl start vip -n rac1
srvctl start vip -n rac2
启动监听：

srvctl start listener
启动数据库：

srvctl start database -d racdb
确认local_listener信息:
检查local_listener信息，如果不正确需要修改，我这里查询是正确的。

--两个节点分别确认：
show parameter local_listener

修改SCAN VIP

查看SCAN VIP当前设置：
[root@rac1 grid]# srvctl config scan
SCAN name: rac-scan, Network: 1/192.168.110.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac-scan/192.168.220.150

[grid@rac1 cssd]$ srvctl stop scan_listener
[grid@rac1 cssd]$ srvctl stop scan

[grid@rac1 cssd]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is not running
[grid@rac1 cssd]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is not running

使用root用户修改SCAN VIP
注意：root用户执行修改，且确认/etc/hosts映射关系已修改为新的scan VIP。
[root@rac1 grid]# srvctl modify scan -n rac-scan
[root@rac1 grid]#

[grid@rac1 cssd]$ srvctl modify scan_listener -u
[grid@rac1 cssd]$

[root@rac1 grid]# srvctl config scan
SCAN name: rac-scan, Network: 1/192.168.110.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac-scan/192.168.110.50

[root@rac1 grid]# srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
[root@rac1 grid]#

至此修改完成，学习巩固下这个操作
