Trafodion安裝Python安裝程序的問題

Question

我是trafodion的新手，我嘗試根據apache的trafodion網站在python安裝程序上在CDH 5.7上安裝traofdion。

[root@node1 python-installer]# ./db_install.py 
********************************** 
Trafodion Installation ToolKit 
********************************** 
Enter HDP/CDH web manager URL:port, (full URL, if no http/https prefix, default prefix is http://): http://10.1.1.10:7180 
Enter HDP/CDH web manager user name [admin]: 
Enter HDP/CDH web manager user password: 
Confirm Enter HDP/CDH web manager user password: 

***[ERROR]: Host [node1]: Failed to connect using ssh. Be sure: 
1. Remote host's name and IP is configured correctly in /etc/hosts. 
2. Remote host's sshd service is running. 
3. Passwordless SSH is set if not using 'enable-pwd' option. 
4. 'sshpass' tool is installed and ssh password is correct if using 'enable-pwd' option. 

還要檢查這些錯誤 1./etc/hosts和主機名被修正

[root@node1 python-installer]# hostname 
node1.trafodion.local 
[root@node1 python-installer]# cat /etc/hosts 
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 
::1   localhost localhost.localdomain localhost6 localhost6.localdomain6 
10.1.1.10 node1.trafodion.local node1 
10.1.1.11 node2.trafodion.local node2 
10.1.1.12 node3.trafodion.local node3 
10.1.1.13 node4.trafodion.local node4 

2. sshd服務正在運行

[root@node1 python-installer]# service sshd status 
openssh-daemon (pid 3480) is running... 

3.每兩個節點可以使用密碼的ssh

4.sshpass未安裝

[root@node1 python-installer]# sshpass 
-bash: sshpass: command not found 

謝謝你的幫助。

請嘗試ssh到NODE1 ..節點4使用手動root用戶，它會更容易檢測到任何ssh登錄的問題。如果手動ssh可以工作，安裝程序也應該工作。
