打開Openstack dashboard出現Internal Server Error

最近研究openstack，想把本身遇到的問題記錄下來，同時若是有別的朋友也碰到一樣問題的時候能夠有個參考。

 

此次的問題是在openstack搭建好以後，dashboard自己是能用的，可是在某一天後，忽然發現打開dashboard後出現Internal Server Error. 因而乎在網上找答案可是沒有，那就本身動手解決吧。

 

首先打開dashboard的log文件，個人是：~/log/horizon.log.

發現下面的error 信息：

2015-04-28 01:39:55.380169 Traceback (most recent call last):

2015-04-28 01:39:55.381886     from local.local_settings import *  # noqa
2015-04-28 01:39:55.381977   File "/opt/stack/horizon/openstack_dashboard/wsgi/../../openstack_dashboard/local/local_settings.py", line 117, in <module>
2015-04-28 01:39:55.382078     os.path.join(LOCAL_PATH, '.secret_key_store'))

2015-04-28 01:39:55.382494 FilePermissionError: Insecure key file permissions!

 

初步判斷是文件的權限問題，根據os.path.join(LOCAL_PATH, '.secret_key_store') 找到/opt/stack/horizon/openstack_dashboard/local/.secret_key_store, 並發現對這個文件擁有全部的權限，很奇怪爲啥會出現permission的問題

登錄到另一臺dashboard正常work的機器上發現

而後決定刪除這兩個文件，再次刷新dashboard的url,很神奇的是work了，同時也發現該目錄下新產生了這兩個文件，而且權限和上圖同樣。

 

這個問題誤打誤撞的解決了，可是在操做openstack過程當中發現openstack很不穩定，有的功能開始是好的，過一兩天就很差用了，或是裝一個東西怎麼也裝不上，而後多重裝幾回就行了，仍是不明白其中的緣由，可是要多學習，多探索！ ^_^
