1.首先删除配置：
/u01/grid/grid_home/perl/bin/perl -I/u01/grid/grid_home/perl/lib -I/u01/grid/grid_home/crs/install /u01/grid/grid_home/crs/install/roothas.pl -deconfig -force -verbose
Using configuration parameter file: /u01/grid/grid_home/crs/install/crsconfig_params
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Stop failed, or completed with errors.
CRS-4639: Could not contact Oracle High Availability Services
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

2.重新执行root.sh
[root@localhost ~]#/u01/grid/grid_home/root.sh
[root@localhost ~]#/u01/grid/grid_home/perl/bin/perl -I/u01/grid/grid_home/perl/lib -I/u01/grid/grid_home/crs/install /u01/grid/grid_home/crs/install/roothas.pl

在执行root.sh脚本时出现Adding daemon 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/null bs=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)

3.Stand-Alone Server 的状态
[root@localhost bin]# cd /u01/grid/grid_home/bin
[root@localhost bin]# ./crsctl check has
CRS-4638: Oracle High Availability Services is online

[root@localhost bin]# ./crsctl check css
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon

[root@localhost bin]# ./crsctl check evm
