MongoDBデータベースが消えた

私のmongoデータベース全体は消えてしまったようです（これは私の論文のためです。MongoDBデータベースが消えた

私は（それがどんな編集なしの月のために働いされています）とpymongoを使用してモンゴへの書き込みツイートを取得するいくつかのコードを実行していることだし、私はこのエラーを取得する：

私はMongoのコンソールにアクセスしようとしましたが、受信：

は、それから私は私がコンソールにアクセスすることを許可され、手動でmongodと呼ばれるが、今の代わりに、複数のshow dbsを有するので単に与えます：

オペレーティングシステムの公開ファイルの制限に達しました。制限を増やすには/etc/security/limits.confを編集してください。これはあなたをガイドすることがあります：http://stackoverflow.com/questions/20901518/ubuntu-too-many-open-files –

@MustafaGenç素早く答えてくれてありがとうございますが、なぜコンソールからデータベースにアクセスできないでしょうか？または、すでに書き込まれたデータにアクセスするにはどうすればよいですか？ – ZeerakW

@MustafaGenç制限を更新しようとしましたが、これ以上制限について文句を言うことはありませんが、以前に書かれたデータベースにはまだアクセスできません。 – ZeerakW

あなたはすべてデフォルト（元ulimitのエラーが、/ usr /ローカルの/ var/MongoDBのをログに記録されたのに対し、DBPATHは、/データ/ DBである）でMongoDBのを実行しているように、それが見えます。

どのパスが正しいと思われますか？

間違ったdbpathで手動で実行した場合は、空のdbが表示されます。

このプロセスを完全に停止しなかった場合（kill-9など）、このインスタンスが破損している可能性があります（うまくいけば不正なdbpathになっている可能性があります）。

まず、/ usr/local/var/mongodbパスのコピーをとります。

正しいdbpath、user、permissions、およびulimitの設定で以前の/etc/security/limits.confの提案がMacで役に立たなかったmongodプロセスを再起動してみてください。

これが役に立たない場合、最初にアップグレードを試してみてください（3.2.0はかなり古いです）。

ちょっと、どのパスが正しいと思われているのかよくわからないのですか？一方のパスはロギングパスで、もう一方のパスはデータベースパスです。また、3.2.7にアップデートしようとしました（最新のものは自家製です）。 – ZeerakW

あなたは出血の天才です！正しいDBパスは/ usr/local/var/mongodbで、ulimitを更新した後は完全に回復しました！ – ZeerakW

あなたの歓迎！時々バックアップをする価値があるかもしれません;） – jimoleary
