RAC2执行root.sh报错CRS-2679

环境：安装云上的rac，其中4块网卡，2块绑定做public网卡，另外2块为心跳网卡

问题一：ssh不能打开图形界面

解决一：最简单的方式是使用VNC（尤其是使用VPN,堡垒机等的情况下）

其中VNC打开图形界面export DISPLAY=:x.0

"x"是要看/etc/sysconfig/vncserver 中VNCSERVERS设置的数字是几

例：# vi /etc/sysconfig/vncserver

VNCSERVERS="2:root"

#export DISPLAY=:2.0

问题二：安装集群软件时使用图形化界面建立SSH互信不能通过

解决二：用root用户手动跑grid安装目录下的脚本

./sshUserSetup.sh -user grid -hosts "节点1主机名 节点2主机名 " -advanced -noPromptPassphrase然后图形化界面输入grid密码后直接点击下一步，后台会自行检测通过

问题三：在集群软件安装过程中，节点1执行root.sh报错

# /u01/app/11.2.0/grid/root.sh

原因分析：由于系统资源繁忙，导致创建失败，一般情况下，跟主机性能偏差有关，该问题一般出现在虚拟机环境中

解决三：进入$grid_home/install/运行./roothas.pl -deconfig -force -verbose后，重新执行root.sh

问题四：节点2执行root.sh报错

原因：2节点的HAIP不互通，也就是ifconfig下169段的地址

解决四：找云上主机工程师将HAIP调通，这个主要可以参考包子大师的http://www.talkwithtrend.com/Article/178531，真的是瞎猫碰到死耗子找到的，如果分析日志的话可以先从集群日志—asm日志—根据信息找其他日志，记住RAC环境2节点心跳网卡的HAIP必须可以相互ping通。
