没有端口分配给 Strongloop 应用程序
No Ports Assigned to Strongloop App
我正在尝试将 strongloop 应用程序部署到 Digitalocean 远程盒子 运行ning Strongloop Process Manager。我已经成功 运行 部署命令如下：
USER ~/projects/loopback/places-api $ slc deploy http://IPADDRESS deploy
Counting objects: 5215, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (4781/4781), done.
Writing objects: 100% (5215/5215), 7.06 MiB | 4.27 MiB/s, done.
Total 5215 (delta 1130), reused 0 (delta 0)
To http://104.131.66.124:8701/api/services/1/deploy/default
* [new branch] deploy -> deploy
Deployed `deploy` as `placesAPI` to `http://IPADDRESS:8701/`
接下来，我通过 运行 执行以下命令检查我的 Strongloop 应用程序的状态：
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
此时，我无法通过访问 IPADDRESS:3001 来访问我的应用程序，正如 Strongloop 文档所建议的那样，并且在端口 3001 上的上述应用程序状态 运行ning 中没有列出任何进程正如 Strongloop 文档所预期的那样。
将我的应用程序状态与 Strongloop 文档中显示的这种部署状态下的应用程序状态进行比较，看来我应该有一些进程侦听端口 3001，但我的应用程序中没有 运行ning。
这是 Strongloop 文档中显示的应用程序状态：
$ 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
注意侦听端口 3001 的其他进程。
我的问题是：如何让我的 strongloop 应用程序进入 运行 并监听这些端口？

只是为了把这个放在一个答案中，从 package.json 我们可以看到你已经包含了 loopback-connector-postgresql 并且在日志中我们看到尝试连接到端口 5432 这是该 DBMS 的默认值。它正在尝试在本地主机 (127.0.0.1) 上进行连接，我的猜测是 Postgres 要么没有安装在您的 Digital Ocean 机器上，要么没有 运行ning。您需要更新数据库的配置，或在您的 DO droplet 上安装（和 运行）数据库。
如果您对开发和生产有不同的配置，那么您可以设置一个 environment-specific datasources config file：例如 datasources.production.json。在该文件中，您将放置您的产品配置，而在 datasources.json 中，您将拥有您的开发（本地）配置。使用此方法时，请务必将 DO droplet 上的 NODE_ENV 变量设置为 production（以匹配 prod 数据源配置文件的名称）。
