問題四

1. 啟動 cinder quantum nova 等服務時出現以下錯誤訊息，且確定 qpidd.conf 設定無誤也運作正常。
   

   [root@kvm4 ~(keystone_myuser)]# tail /var/log/cinder/*
   
   ==> /var/log/cinder/volume.log <==
   2015-04-25 10:37:50    ERROR [cinder.openstack.common.rpc.impl_qpid] \
   Unable to connect to AMQP server: Error in sasl_client_start (-1) \
   SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure.  \
   Minor code may provide more information (\
   Credentials cache file '/tmp/krb5cc_165' not found). Sleeping 2 seconds
   

2. 原因為安裝了 cyrus-sasl-gssapi 套件做認證，但又沒設定好。
3. 解決方式：因 openstack 不使用此認證，故將其移除再重新啟動 qpidd 服務即可。
   

   [root@kvm4 ~(keystone_myuser)]# yum remove cyrus-sasl-gssapi
   [root@kvm4 ~(keystone_myuser)]# /etc/init.d/qpidd restart
   

4. 再次重新啟動 ciner 相關服務，已無錯誤訊息。
   

   [root@kvm4 ~(keystone_admin)]# cat a.sh
   rm /var/log/cinder/* -f
   /etc/init.d/openstack-cinder-scheduler restart
   /etc/init.d/openstack-cinder-api restart
   /etc/init.d/openstack-cinder-volume restart
   sleep 4
   tail /var/log/cinder/*
