MongoDB活动状态失败

我的服务器在Nginx Ubuntu 16.04 LTS上运行。我想安装mongoDB以便将其与node.js结合使用，然后按照本教程进行操作，但是在编写status命令时我有此内容。

● mongodb.service - High-performance, schema-free document-oriented database
   Loaded: loaded (/etc/systemd/system/mongodb.service; enabled; vendor preset: enabled)

您有解决我问题的任何解决方案吗？如果您有需要完全删除mongodb的解决方案，则可以。我的数据库中没有任何内容，因为这是我的第一次安装。

我尝试了以下命令删除mongodb：

sudo apt-get remove mongodb* --purge

但是我有这个错误

E: Unable to locate package mongodb.service
E: Couldn't find any package by glob 'mongodb.service'
E: Couldn't find any package by regex 'mongodb.service'

但是我确实喜欢本教程所说的。我在mongo.service里面创建了文件/etc/systemd/system

编辑：

用mongod命令，我有这个：

该错误是不言自明的，/etc/mongodb.conf系统上缺少文件，因此您需要创建一个。这个简单的配置将允许您开始mongod

systemLog:
 verbosity: 1
 quiet: true
 traceAllExceptions: false
 path: "/opt/mongo/log/local.log"
 logAppend: true
 destination: file
storage:
 dbPath: "/opt/mongo/db"
 journal:
  enabled: true
processManagement:
 fork: true
net:
 port: 27017
security:
 authorization: disabled

只需为日志/存储设置适当的路径，并确保mongod能够在其中写入。
