oracle RAC集群更改public网络（同一网段，不同网段都适用）

oracle 11g rac
修改IP，主机名无法修改
原IP信息

192.168.1.10  rac01
192.168.1.12  rac02
Private
192.168.56.10  rac01-priv
192.168.56.12  rac02-priv
Vip
192.168.1.13  rac01-vip
192.168.1.14  rac02-vip
SCAN
192.168.1.15  scan

关闭监听和vip

/u01/app/11.2.0.4/grid/bin/srvctl disable vip -i rac01-vip
/u01/app/11.2.0.4/grid/bin/srvctl disable vip -i rac02-vip
/u01/app/11.2.0.4/grid/bin/srvctl disable listener
/u01/app/11.2.0.4/grid/bin/srvctl stop listener
/u01/app/11.2.0.4/grid/bin/srvctl stop vip -n rac01
/u01/app/11.2.0.4/grid/bin/srvctl stop vip -n rac02

所有节点停止crs

/u01/app/11.2.0.4/grid/bin/crsctl stop crs

修改hosts文件
修改后如下:

192.168.1.20  rac01
192.168.1.22  rac02
Private
192.168.56.10  rac01-priv
192.168.56.12  rac02-priv
Vip
192.168.1.23  rac01-vip
192.168.1.24  rac02-vip
SCAN
192.168.1.25  scan

更改网卡IP

vi /etc/sysconfig/network-scripts/ifcfg-eth0

重启网络服务

service network restart

更改后IP信息如下
rac01：


2: eth0: mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:97:3b:ec brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.20/24 brd 192.168.1.255 scope global eth0
    inet6 fe80::a00:27ff:fe97:3bec/64 scope link
       valid_lft forever preferred_lft forever
3: eth1: mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:ee:bf:12 brd ff:ff:ff:ff:ff:ff
    inet 192.168.56.10/24 brd 192.168.56.255 scope global eth1
    inet6 fe80::a00:27ff:feee:bf12/64 scope link
       valid_lft forever preferred_lft forever

rac02

eth0: mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:45:5a:9f brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.22/24 brd 192.168.1.255 scope global eth0
    inet6 fe80::a00:27ff:fe45:5a9f/64 scope link
       valid_lft forever preferred_lft forever
3: eth1: mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:6b:6a:d1 brd ff:ff:ff:ff:ff:ff
    inet 192.168.56.12/24 brd 192.168.56.255 scope global eth1
    inet6 fe80::a00:27ff:fe6b:6ad1/64 scope link
       valid_lft forever preferred_lft forever

重新启动CRS服务

/u01/app/11.2.0.4/grid/bin/crsctl start crs
/u01/app/11.2.0.4/grid/bin/crsctl check crs

输出结果如下时

CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

启动另一个节点crs
2个节点都输出如上结果时，检查进程状态
