勺到PostgreSQL的连接问题

Question

从Spoon连接到数据库时抛出错误消息。

1. 选择显示在屏幕左上角的“查看”选项，右键单击“数据库连接”选项，然后选择“新建”。
2. 在“连接类型”下，选择“ PostgreSQL数据库引擎”。

3. 填写“设置”选项，并在“连接名称”中键入连接的名称。 输入的所有凭据均有效，但仍然收到以下错误消息：

   连接到数据库[XXX-XXX-XXX-XXX]时出错：org.pentaho.di.core.exception.KettleDatabaseException：尝试连接到数据库时发生错误

   连接数据库时出错：（使用类org.postgresql.Driver）连接尝试失败。

   org.pentaho.di.core.exception.KettleDatabaseException：尝试连接数据库时发生错误

   由以下原因引起：org.postgresql.util.PSQLException：连接尝试失败。 在org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl（ConnectionFactoryImpl.java:233）在org.postgresql.core.ConnectionFactory.openConnection（ConnectionFactory.java:64）在org.postgresql.jdbc2.AbstractJdbc2Connection。（AbstractJdbc2Connection.java： 144）在org.postgresql.jdbc3.AbstractJdbc3Connection。（AbstractJdbc3Connection.java:29）在org.postgresql.jdbc3g.AbstractJdbc3gConnection。（AbstractJdbc3gConnection.java:21）在org.postgresql.jdbc4.AbstractJdbc4Connection。（AbstractJdbc4）在org.postgresql.Driver.makeConnection（Driver.java:410）在org.postgresql.Driver.connect（Driver.java:280）在org.postgresql.Driver.makeConnection（Driver.java:410）在org.postgresql.jdbc4.Jdbc4Connection。（Jdbc4Connection.java:24） org.pentaho.di.core.database.Database.connectUsingClass（Database.java:561）处的java.sql.DriverManager.getConnection（未知源）... 56其他原因：java .net.UnknownHostException：PSY-STG-DB1位于java.net.AbstractPlainSocketImpl.connect（未知源 e）位于org.postgresql.core.PGStream。（PGStream.java.net.Socket.connect（未知源）处的java.net.SocksSocketImpl.connect（未知源）处的java.net.PlainSocketImpl.connect（未知源）。 java：61）at org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl（ConnectionFactoryImpl.java:109）... 67更多

   主机名：XXX-XXX-XXX端口：1111数据库名：XXX_XXX_XX

请建议我如何解决此问题

Answer 1

好吧，首先检查一下：

• 服务器已启动并正在运行？ （Postgres）
• 为什么端口是1111而不是5432
• 您可以与pgadmin连接吗？

我认为是配置问题
