chkconfig 啟動腳本失敗，腳本手動執行良好
我最近購買了一個 vps，並嘗試創建一個啟動/重啟腳本來啟動我的 java 程序。我正在執行 CentOS 6。如果我使用以下命令手動執行該腳本，則該腳本可以工作：
服務策略伺服器啟動
但無法自動執行，在 /tmp/test.log 中創建一個文件，並出現以下錯誤：
啟動策略伺服器：失敗
這是裡面的啟動腳本

**編輯：**執行此處發布的答案之一。
這是我剛剛執行該命令時得到的結果

您可以通過以更詳細的方式執行啟動腳本來調試此類問題。
$ bash -x service policyserver start您可能還想將此輸出擷取到日誌文件中。
$ bash -x service policyserver start |& tee policyserver_startup.log然後，您可以查看日誌文件並查看哪個命令失敗。
