我是靠谱客的博主斯文书本，最近开发中收集的这篇文章主要介绍11gR2的安装Grid执行root.sh出现ohasd failed解决方案，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

参考：http://blog.itpub.net/30327022/viewspace-2129259/

系统环境：Linux Server release 7.5

数据库环境：11.2.0.4.0

执行脚本 /u01/app/11.2.0/grid/root.sh，报错如下：
[root@Oraclelinux ~]# /u01/app/11.2.0/grid/root.sh
Performing root user operation for Oracle 11g

The following environment variables are set as:
ORACLE_OWNER= grid
ORACLE_HOME= /u01/app/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:
The contents of "dbhome" have not changed. No need to overwrite.
The contents of "oraenv" have not changed. No need to overwrite.
The contents of "coraenv" have not changed. No need to overwrite.

解决方案:
第一步，回退root.sh脚本操作

[root@Oraclelinux ~]# /u01/app/11.2.0/grid/crs/install/roothas.pl -deconfig -force -verbose
Using configuration parameter file: /u01/app/11.2.0/grid/crs/install/crsconfig_params
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Stop failed, or completed with errors.

CRS-4000: Command Delete failed, or completed with errors.
CRS-4544: Unable to connect to OHAS
CRS-4000: Command Stop failed, or completed with errors.
Successfully deconfigured Oracle Restart stack

第二步：
在执行root.sh脚本时出现Adding cluster to inittab的时候，在另一个窗口使用root立即执行以下命令：

dd if=/var/tmp/.oracle/npohasd of=/dev/nullbs=1024 count=1（等待root.sh成功执行完毕后可以ctrl+c取消这里的命令）

OK，此时Grid 安装通过。
