無法在CENTOS7上配置OrientDB - Java集成

Question

我正嘗試使用orient-db在CENTOS7機器上創建部署我的java web應用程序。 目前我已經在root用戶上設置了Orient-db特權用戶〜/ softwares/$ ORIENTDB_HOME 服務器在初始配置中成功設置了用戶名和密碼並啓動。 現在我想創建一個遠程數據庫通過使用運行console.sh

orientdb> CREATE DATABASE remote:localhost/test root root plocal

後如下create database命令我的Java應用程序進行訪問，但我收到以下錯誤

Creating database [remote:localhost/test] using the storage type [plocal]... Error: com.orientechnologies.orient.core.exception.OStorageException: Cannot create the remote storage: test

Error: com.orientechnologies.orient.core.exception.ODatabaseException: Cannot create database 'test' DB name="test" DB name="test"

Error: com.orientechnologies.orient.core.exception.OStorageException: Cannot create folders in storage with path /softwares/orientdb-community-2.2.5/orientdb-community-2.2.5/databases/test DB name="test"

我嘗試了CHMODing .sh bin目錄以及$ ORIENTDB_HOME/databases目錄，但問題仍然存在。

但是它讓我恕我直言，你所做創建具有plocal

orientdb> CREATE DATABASE plocal:localhost/test root root plocal

但後來我在java的結束

$ java -jar dataloader-jar-with-dependencies.ja

得到以下錯誤分貝與角色和權限混淆。您使用哪個系統用戶來解壓OrientDB？你用哪一個作爲獨立的服務器來運行它？ 我「米問，因爲你能夠在plocal與控制檯創建一個數據庫（plocal意味着嵌入式）。 我猜你用根提取焦油，然後從一個普通用戶登錄shell啓動的服務器。

在最後一步，你都指向一個錯誤的數據庫地址：connecting to:plocal:localhost/asm

如果您正在訪問的plocal分貝（嵌入式），只需使用plocal:/path/to/db/folder

如果您正在訪問由一個獨立的服務器提供的DB，使用remote:SERVER_ADDRESS/db_NAME
