错误提示，无法解析localhost主机！

查看/etc/hosts文件：

[root@hk2 crsd]# cat /etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.56.101  hk1
192.168.56.103  hk2

192.168.56.104 hk1-vip
192.168.56.105 hk2-vip
192.168.56.106 hk-scan

缺少对localhost的解析！

解决方法：

1、编辑/etc/hosts文件

[root@hk1 bin]# cat /etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1  localhost
192.168.56.101  hk1
192.168.56.103  hk2
10.10.10.101  hk1-priv
10.10.10.103  hk2-priv
192.168.56.104 hk1-vip
192.168.56.105 hk2-vip
192.168.56.106 hk-scan

2、删除CRS的配置，重新运行root.sh
