Question

我使用Kubernetes在分布式模式下设置了OrientDB（3.0.10）。我尝试用一些数据填充每个pod的数据库。因此，我在其中一个节点上运行了控制台，并尝试创建数据库，这就是输出：

self.plot = self.plotWidget.addPlot(axisItem={'bottom': axis})

在此节点和群集的其他节点上创建数据库的文件夹：

   orientdb> create database remote:localhost/Test root rootpwd PLOCAL
    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 open database 'Test'
    Error: com.orientechnologies.orient.server.distributed.ODistributedException: No active nodes found to execute command: sql.select from OUser where name = ? limit 1
orientdb {server=remote:localhost/Test}>

但是，当我尝试通过控制台从每个节点连接到数据库时，出现错误：

+-----------------------+------+---------------------------+-----+---------+---------------+---------------+------------------------+

此消息出现在群集的日志中：

orientdb> connect remote:localhost/Test root rootpwd
Connecting to database [remote:localhost/Test] with user 'root'...
Error: com.orientechnologies.orient.core.exception.ODatabaseException: Cannot open database 'Test'
    DB name="Test"
Error: com.orientechnologies.orient.core.exception.ODatabaseException: Cannot open database 'Test'
Error: com.orientechnologies.orient.server.distributed.ODistributedException: No active nodes found to execute command: sql.select from OUser where name = ? limit 1
orientdb {server=remote:localhost/Test}>

这种行为的原因可能是什么？我应该在集群配置中修复某些问题吗？我关注了this tutorial
