經過重啟nova、neutron、keystone、glance以及httpd均無用，后來開始一點點檢查配置文件，發現lock_path路徑如下，檢查文件權限時發現是root
[oslo_concurrency] # # From oslo.concurrency # # Enables or disables inter-process locks. (boolean value) #disable_process_locking = false # Directory to use for lock files. For security, the specified directory # should only be writable by the user running the processes that need locking. # Defaults to environment variable OSLO_LOCK_PATH. If external locks are used, # a lock path must be set. (string value) # lock_path = $state_path/lock lock_path = /var/lib/neutron/tmp [oslo_messaging_amqp] # # From oslo.messaging
修改權限
chown -R neutron:neutron /var/lib/neutron
再次重啟systemctl restart neutron-linuxbridge-agent.service之后日志正常，重啟鏡像實例發現可以獲取ip
總結：對於服務報錯檢查應該先從日志入手，再檢查配置，分開每個服務逐一檢查。對於本次OpenStack安裝錯誤，也警醒自己，需要真正了解每個服務，端口和配置內容，服務原理。可能就因為文件權限這種小問題，就會導致服務異常，還是要細致認真，也希望能幫助到更多的人。
