搭建好了keystone服務後，對自己本身的認證是成功的 說明keystone配置是正確的。

之後開始配置glance服務，配置好了，出現瞭如下報錯。

[ [email protected] ~]# glance  image-list

503 Service Unavailable: The server is currently unavailable. Please try again at a later time. (HTTP 503)

開始以為是環境變數設定的問題。然後如下操作：

echo"export OS_IMAGE_API_VERSION=2"|tee-a admin-openrc.sh demo-openrc.sh
 

source admin-openrc.sh


然後執行 glance image-list

還是出現上面的這個報錯。

然後我就看了下日誌，出現瞭如下報錯：

 4-21 09:44:12.712 29975 ERROR keystonemiddleware.auth_token [-] Bad response code while validating token: 400
2017-04-21 09:44:12.714 29975 WARNING keystonemiddleware.auth_token [-] Identity response: {"error": {"message": "Expecting to find domain in user - the server could not comply with the request since it is either malformed or otherwise incorrect.

2017-04-21 09:44:12.716 29975 CRITICAL keystonemiddleware.auth_token [-] Unable to validate token: Failed to fetch token data from identity server

意思貌似是glance認證keystone出現了問題。 Unable to validate token: Failed to fetch token data from identity server 之後比對了下/etc/glance/glance-registry.conf 和 /etc/glance/glance-api.conf 檔案 發現了 /etc/glance/glance-api.conf 檔案缺少了 user_domain_id = default
project_name = service
導致glance連結keystone失敗。所以添加了. 重啟下服務： [[email protected] ~]#  systemctl restart openstack-glance-api
[[email protected] ~]# systemctl restart openstack-glance-registry 最後就是見證奇蹟的時刻。。
[[email protected] ~]# glance  image-list

這只是一個思路，openstack這個虛擬化操作是非常繁瑣的 ，所以部署的過程中要注意些配置檔案。不然出了錯誤 都不知道怎麼去解決。
