Symptoms
當 RabbitMQ 在 DPC 軟體更新後無法啟動時,狀態會顯示 RabbitMQ 服務 (
rabbitmq-server) 正在啟動,但仍未完成:

# RabbitMQ 記錄顯示在啟動期間存取訊息存放區時發生錯誤。例如,在 /var/log/dpc/rabbitmq/rabbit@<DPC Hostname>.log,在嘗試重建索引時顯示 RabbitMQ 失敗:

Cause
由於佇列中有大量卡住訊息,因此 RabbitMQ 無法啟動。
在此範例中,佇列中有超過 800 MB 的數據:
在此範例中,佇列中有超過 800 MB 的數據:

Resolution
若要解決此問題,請使用以下程序重建 RabbitMQ 資源:
實驗室環境的輸出範例:
- 拍攝 DPC 虛擬機器的快照 ,或執行 DPC 伺服器的完整備份。
- SSH 至 DPC ,並以「admin」身分登入,然後將使用者變更為 root:
su -
- 停止 RabbitMQ 服務 (
rabbitmq-server) 中的新增命令:
service rabbitmq-server stop
- 將目錄變更 為
/var/lib/dpc/rabbitmq/mnesia:
cd /var/lib/dpc/rabbitmq/mnesia
- 如果有足夠的可用空間
/tmp,將資料複製到/tmp(選配):
cp -rp * /tmp
- 移除以下項目的資料
/var/lib/dpc/rabbitmq/mnesia使用以下命令:
rm -rf *
- 重新啟動 RabbitMQ 服務,檔案位於
/var/lib/dpc/rabbitmq/mnesia應重新產生:
service rabbitmq-server start
- 重新啟動 DPC 服務:
/usr/local/dpc/bin/dpc restart
實驗室環境的輸出範例:
圖 1:顯示 RabbitMQ 在以下位置重新產生資料結構的範例:
/var/lib/dpc/rabbitmq/mnesia 在啟動期間
- 登入 DPC UI ,確認 DPC 是否如預期運作。
- 刪除先前移至的子資料夾
/tmp如果數據已在步驟 5 中複製。 - 服務恢復正常時,請刪除已拍攝的 DPC 虛擬機快照 。
