mongodb - 从现有项目中加载docker容器，mongo将不会连接到数据库Ubuntu 18.04

Question

最初，我遇到了一个问题，即mongod服务完全停止工作。随即，我完全卸载了mongodb并重新安装了它，并按照以下每个线程的说明进行操作:https://askubuntu.com/questions/921753/failed-to-start-mongod-service-unit-mongod-service-not-found

这导致mongod服务最终启动。

为了使其正常工作，我还必须遵循此线程的指示:
mongo - couldn't connect to server 127.0.0.1:27017

到目前为止，此配置仅工作了1次，那是在我按照说明删除mongod目录中的.lock文件然后修复mongod之后。

我还试图删除此处所述的 socks 文件:MongoDB Failing to Start - ***aborting after fassert() failure

全部项目重置

然后，我尝试将项目完全断开。关闭后端的nodemon，退出前端的ng服务，停止并删除mongo docker容器...然后重试。在解决所有问题之后，这是我的分步过程:

重新启动mongod服务

sudo service mongod restart

重新启动前端(从前端目录执行)

ng serve frontend

重新启动后端(从后端目录执行)

npx nodemon backend 

重新启动mongo容器(从deploy目录执行，mongo是docker容器名称，我从现有提供的部署脚本中构建它)

sudo docker-compose up -d mongo
sudo docker ps -a # check container was created and is running

调试信息:

sudo service mongod status

  Enable MongoDB's free cloud-based monitoring service, which will then receive and display
  metrics about your deployment (disk utilization, CPU, operation statistics, etc).

  The monitoring data will be available on a MongoDB website with a unique URL accessible to you
  and anyone you share the URL with. MongoDB may use this information to make product
  improvements and to suggest MongoDB products and deployment options to you.

  To enable free monitoring, run the following command: db.enableFreeMonitoring()
  To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

因此，这里发生了一些奇怪的事情，它没有从项目中找到数据库，我也不知道为什么。据我所知，它将创建一个包含我的系统详细信息的新数据库。
我该如何解决这个问题并连接到项目数据库？我不能再走了。

Answer 1

它已经解决了。首先，我发现我不需要在本地运行mongod服务，因为mongo已经包含在docker容器中。但这实际上根本不是数据库问题。发生了一些错误，例如有一个代理，但是命令已更改为执行连接，端点在localhost上，但不应在此处，而且我期望看到的内容已被粗心的推送隐藏了来自另一个开发者。娱乐时间!但我们现在可以继续前进。感谢尝试提供帮助的人!
