几分钟后带有 NodeJS 的 PM2 崩溃并在循环中重新启动

如何解决几分钟后带有 NodeJS 的 PM2 崩溃并在循环中重新启动

我有一个 NodeJs+Express+Mongodb 应用程序，我正在尝试在我的 vps 上运行它。 我愿意：

pm2 start server

[PM2] Applying action restartProcessId on app [server](ids: [ 1 ])
[PM2] [server](1) ✓
[PM2] Process successfully started
┌────┬────────────────────┬──────────┬──────┬───────────┬──────────┬──────────┐
│ id │ name               │ mode     │ ↺    │ status    │ cpu      │ memory   │
├────┼────────────────────┼──────────┼──────┼───────────┼──────────┼──────────┤
│ 1  │ server             │ fork     │ 991  │ online    │ 0%       │ 13.8mb   │
└────┴────────────────────┴──────────┴──────┴───────────┴──────────┴──────────┘
Current process list running is not in sync with saved list. App app differs. Type 'pm2 save' to synchronize.

一切正常。但是几分钟后 pm2 出现错误并每 1 秒在循环中重新启动：

有人可以帮助我了解出了什么问题吗？在 localhost 中一切正常，但在生产中运行对我来说非常困难。

解决方法

尝试在没有 PM2 的情况下启动您的应用程序，通常这表示节点实例失败，因此执行常规节点 [appname] 将生成您的节点应用程序失败的地方，可能是缺少包。

阅读消息：正在运行的进程未同步。

您需要pm2 save。
