我正在尝试将strongloop应用程序部署到运行Strongloop Process Manager的Digitalocean远程控制台。我已经成功运行deploy命令，如下所示：
slc ctl -C http://IPADDRESS:8701
Service ID: 1
Service Name: placesAPI
Environment variables:
No environment variables defined
Instances:
Version Agent version Debugger version Cluster size Driver metadata
5.1.0 2.0.2 n/a 1 N/A
Processes:
ID PID WID Listening Ports Tracking objects? CPU profiling? Tracing? Debugging?
1.1.1050 1050 0
1.1.2065 2065 49
接下来，我通过运行以下命令检查我的Strongloop应用程序的状态：
$ slc ctl -C http://prod.foo.com:7777
Service ID: 1
Service Name: appone
Environment variables:
No environment variables defined
Instances:
Version Agent version Cluster size
4.0.30 1.4.15 4
Processes:
ID PID WID Listening Ports Tracking objects? CPU profiling?
1.1.22555 22555 0
1.1.22741 22741 5 prod.foo.com:3001
1.1.22748 22748 6 prod.foo.com:3001
1.1.22773 22773 7 prod.foo.com:3001
1.1.22793 22793 8 prod.foo.com:3001
此时，我无法通过访问IPADDRESS：3001来访问我的应用程序，因为Strongloop文档会建议并且根据Strongloop文档，在端口3001上运行的上述应用程序状态中没有列出任何进程。
将我的应用状态与Strongloop文档中显示的此部署状态下的应用状态进行比较，看来我应该有一些进程正在侦听端口3001，这些进程未在我的应用中运行。
以下是Strongloop文档中显示的应用状态：

}
请注意侦听端口3001的其他进程。
我的问题是：如何让我的strongloop应用程序运行并收听这些端口？
如果有帮助，请查看我的package.json和config.json文件：

来自log-dump的日志中也存在此错误：
// Capture screen
Robot clientrobot = new Robot();
Rectangle robotrectangle = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
BufferedImage image = clientrobot.createScreenCapture(robotrectangle);
String imageStringByte = null;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ImageIO.write(image, "jpg", bos);
byte[] imageBytes = bos.toByteArray();
imageStringByte = Base64.getMimeEncoder().encodeToString(imageBytes);
bos.close();
output.writeObject("RECEIVEDESKTOP-" + imageStringByte);
output.flush();
答案 0 :(得分：1)
只是回答一下，从var dataItem = e.Item.DataItem as WhateverTheUnderlyingTypeIs;
我们可以看到您已经包含了package.json，在日志中我们看到尝试连接到端口 5432 这是该DBMS的默认值。它试图连接localhost（loopback-connector-postgresql），我的猜测是Postgres没有安装在你的数字海洋盒子上，或者没有运行。您需要更新数据库的配置，或者在DO droplet上安装（并运行）数据库。
如果您对开发与生产有不同的配置，那么您可以设置environment-specific datasources config file：127.0.0.1。在该文件中，您将放置您的prod配置，并在datasources.production.json中您将拥有您的dev（本地）配置。使用此方法时，请务必将DO droplet上的datasources.json变量设置为NODE_ENV（以匹配prod数据源配置文件的名称）。
