首先确认本身的防火墙已经关闭 node
安装Oracle 11.2.0.3 的RAC,在Grid 安装时报错: bash
[INS-41112]Specified network interface doesnt maintain connectivity across cluster nodes ssh
首先尝试在节点间ping 各个IP 地址没有问题。 测试
由于使用安装程序作的SSH 验证,因此尝试测试ssh远程链接是否还须要确认: spa
[grid@rac2 ~]$ ssh rac2 dae ci
bash: dae: command not found it
[grid@rac2 ~]$ ssh rac2 date date
