最近測試需要，在VMWARE上安裝10g RAC，在安裝CRS時，報如下錯誤：
2個節點間的SSH等效性已經配置了，並且測試過了。 瞅着屏幕 思考了幾分鐘，發現我這次與往常的一點點不一樣，這次我的主機名是有域名的，如我的/etc/hosts文件爲：
[root@amto04 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
#127.0.0.1 amto04.ligledba.com amto04 localhost.localdomain localhost
#::1 localhost6.localdomain6 localhost6
127.0.0.1 localhost
#Public
192.168.1.9 amto04.ligledba.com amto04
192.168.1.10 amto05.ligledba.com amto05
#Virtual
192.168.1.11 amto04-vip.ligledba.com amto04-vip
192.168.1.12 amto05-vip.ligledba.com amto05-vip
#Private
192.168.10.123 amto04-priv.ligledba.com amto04-priv
192.168.10.124 amto05-priv.ligledba.com amto05-priv
我僅在2個節點執行了如下命令:
ssh amto04 date
ssh amto04-priv date
ssh amto05 date
ssh amto05-priv date
而沒有在2個節點上執行如下命令：
[oracle@amto05 app]$ ssh amto04.ligledba.com date

在2個節點均執行後，問題解決！
