节点1上通过netca修改为192.168.10.10后，依然为127.0.0.1

 

检查hosts文件

发现127.0.0.1指向node1

[root@node1 ~]# more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1  node1.localdomain node1 localhost.localdomain localhost
::1  localhost6.localdomain6 localhost6
#node1
192.168.10.10  node1.localdomain      node1
192.168.10.11  node1-vip.localdomain      node1-vip
192.168.20.10  node1-priv.localdomain      node1-priv

#node2
192.168.10.20  node2.localdomain      node2
192.168.10.21  node2-vip.localdomain      node2-vip
192.168.20.20  node2-priv.localdomain      node2-priv

#scan-ip
192.168.10.30  scan-cluster.localdomain scan-cluster

 

删掉127.0.0.1中node1信息

reloda lsnrctl

无效

 

检查hosts文件

删除127.0.0.1中node1.localdomain信息

reload lsnrctl

无效

 

因为不了解crs节点lisenter的启动流程，推断需要reload crs节点的lisenter信息

通过srvctl stop/start lisenter重启

恢复正常
