### 質問内容

以下のエラーの解決方法を教えてください。

```

    Data directory /data/db not found., terminating
    
```

### 現状

以前mongoDBを起動したときは使えたのだが強制終了してしまったせいか、再度起動できなくなってしまいました。

```

    $ sudo service mongod start
    mongod: unrecognized service
    
```

```

    $ mongod

ここで

```

```

より、dbというディレクトリがないことがわかりました。一応見てみると、

```

    /data$ ls
    db
    /data$ cd db
    -bash: cd: db: No such file or directory
    
```

となっていました。  
このコードの2行目に「db」とある気がするのですが、とりあえず起動できません。

ディレクトリを作れということなのかと思い、同じ階層に「db1」というものを作りました。

```

    /data$ mkdir db1
    /data$ ls
    db  db1
    
```

その後、

```

    $ mongod -dbpath /data/db1

ここまでやってもmongodbは起動できませんでした。  
どういう直し方をすればよいのかわからないので、投稿させていただきました。  
宜しくお願いいたします。

question
ubuntu mongodb
mongoDBのパスの通し方を教えてください
エラーログのうち、

```

    "uname" : { "sysname" : "Linux", "release" : "4.4.0-18362-Microsoft", "version" : "#1049-Microsoft Thu Aug 14 12:01:00 PST 2020", "machine" : "x86_64" }
    
```

の部分からすると、WSL: Windows Sybsystem for Linuxを使っていると思います。

しかしMongoDBは公式にはWSLをサポートしていません。マニュアルの[Supported
Platforms](https://docs.mongodb.com/manual/administration/production-
notes/#supported-platforms)に記載がありません。クラッシュしているのはこのためだと思われます。

まずは普通のLinux環境でやり直すか、もしくはWindowsを使うのであればWindows版のMongoDBをインストールしてみてください。
