安裝openstack踩的一個坑

Openstack Mitaka在圖形化界面的時候出現以下報錯：

<code>[root@linux-node1 ~]</code><code># openstack server create --flavor m1.tiny --image cirros --nic net-id=2d79dc77-be66-4850-af01-8e6946f16035 --security-group default --key-name mykey provider-instance</code>

<code>Unexpected API Error. Please report this at http:</code><code>//bugs</code><code>.launchpad.net</code><code>/nova/</code> <code>and attach the Nova API log </code><code>if</code> <code>possible.</code>

<code><class </code><code>'neutronclient.common.exceptions.Unauthorized'</code><code>> (HTTP 500) (Request-ID: req-1d4cf44f-8b06-43e0-8392-25296b29eecb)</code>

查了下網上資料，各種奇葩版本都有，但是對我的這個問題沒有任何效果，核查下配置檔案：

按照報錯提示，檢查我的nova配置，檢查控制節點和計算節點，也沒發現有啥異常

<code>grep</code> <code>'ERROR'</code> <code>/var/log/nova/</code><code>*</code>

<code>grep</code> <code>'ERROR'</code> <code>/var/log/neutron/</code><code>*</code>

<code>grep</code> <code>'ERROR'</code> <code>/var/log/glance/</code><code>*</code>

<code>grep</code> <code>'ERROR'</code> <code>/var/log/keystone/</code><code>*</code>

<code></code>後來排查發現（自己在編輯neutron的時候，忘記添加rpc_backend = rabbit）：

在計算節點後控制節點都添加後，重新開機neutron相關服務，然後再次執行建立雲主機的操作

<code>檢視發現雲主機已經生效</code>

到此，問題得到解決，OpenStack的配置是個細心活，需要明白它的各個元件的關聯，這樣排除故障的時候會有的放矢。
