OrientDB - 如何在群集服务器上创建数据库？

我创建了两个默认配置，群集状态节点：OrientDB - 如何在群集服务器上创建数据库？

"members": [{ 
    "id": "192.168.1.101:2434", 
    "listeners": [{"protocol": "ONetworkProtocolBinary", "listen": "192.168.1.101:2424"}, {"protocol": "ONetworkProtocolHttpDb", "li 
80"}], 
    "alias": "192.168.1.101:2434", 
    "status": "aligning" 
    }, { 
    "id": "192.168.1.102:2435", 
    "listeners": [{"protocol": "ONetworkProtocolBinary", "listen": "192.168.1.101:2425"}, {"protocol": "ONetworkProtocolHttpDb", "li 
80"}], 
    "alias": "192.168.1.101:2435", 
    "status": "aligning" 
    }], 
"name": "_hzInstance_1_orientdb", 
"local": "192.168.1.101:2435" 
}

，但是当我使用Java API连接到一台服务器，并试图建立一个数据库，发生异常时，

admin = new OServerAdmin(PATH); 
      admin.connect("root", "password"); 

      if (!admin.existsDatabase()) { 
       admin.createDatabase("document", "local"); 
      }

为什么会发生这种情况？我如何在群集服务器上创建数据库？

THX。

数据库的初始创建必须在群集外完成。然后将数据库复制到所有服务器并启动群集。

感谢您的回答。所以我需要在本地机器上启动服务器，创建数据库，然后复制到201和204，然后重新启动201,204。这些操作是否有任何文件？ – niklaus

我们正在更新有关群集上的新内容的文档。但它只是目录的一个副本。 – Lvca

听起来像一个黑客，'distributed-config.json'已被复制。重新启动我的双节点群集中的第二个节点后，其他数据库文件会自动获取。似乎只有最后一步没有完全自动化。 – Dag
