Question

HeJ小鼠，我正在尝试与数字海洋上的orientdb服务器建立远程连接。

然而，我尝试连接：

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

我收到以下错误PyOrientConnectionPoolException: Server sent empty string

     72                 )

我正在运行pyorient v 1.5.4和Anaconda3 python 3.5发行版。

任何提示？

Answer 1

我发现了我的错误，端口值上的一个愚蠢的错误应该是port:2424而不是属于OrientDB studio的port:2480。

如何使用pyorient驱动程序建立与OrientDB分布式数据库的远程连接？
