Question

在Azure中使用managed Postgres database时，Corda节点无法在启动时连接到数据库。

我的node.conf包含this answer中推荐的标准Postgres配置。

     dataSourceProperties = {
        dataSourceClassName = "org.postgresql.ds.PGSimpleDataSource"
        dataSource.url = "jdbc:postgresql://[HOST]:[PORT/[DATABASE]"
        dataSource.user = [USERNAME]
        dataSource.password = [PASSWORD]
    }
    database {
        schema = "corda"
        transactionIsolationLevel = "READ_COMMITTED"
    }

如何确保Postgres通过SSL连接？

Answer 1

Postgres允许直接在jdbc字符串中设置ssl模式。请参见下面的更新配置，其中包括“？ssl = true”。

     dataSourceProperties = {
        dataSourceClassName = "org.postgresql.ds.PGSimpleDataSource"
        dataSource.url = "jdbc:postgresql://[HOST]:[PORT/[DATABASE]?ssl=true"
        dataSource.user = [USERNAME]
        dataSource.password = [PASSWORD]
    }
    database {
        schema = "corda"
        transactionIsolationLevel = "READ_COMMITTED"
    }

Azure Postgres数据库需要来自Corda的SSL连接
