如何使用pyorient驅動程序建立與OrientDB分布式數據庫的遠程連接？

Question

Hej，我正在嘗試建立到我在數字海洋上的orientdb服務器的遠程連接。

但是，我嘗試通過以下方式進行連接：

client =pyorient.OrientDB(host='remote.host.ip', port=2480)
cluster_info = client.db_open(db_name, db_username, db_password)

我收到以下錯誤PyOrientConnectionPoolException: Server sent empty string

     72                 )

我正在運行pyorient v 1.5.4和Anaconda3 python 3.5發行版。

有什么提示嗎？

我發現了我的錯誤，這是端口值上的一個愚蠢錯誤，它應該是port:2424而不是屬於OrientDB studio的port:2480 。
