サーバをリブートした後にデータベースを再起動しようとしたときに、次のエラーが発生しました。私は誰かが1年半前に同じエラーを投稿したのを見ましたが、そこに提案された解決策は、yaml設定の問題ではないため（DBはかなり長い間実行されていたため）、私の状況には当てはまりませんでした。私は最後にログを含めました。助けてくれてありがとう。mongodエラー：子プロセスがエラー番号14で終了しました
sudo mongod --fork --logpath /nas/is1/bin/mongodb/data/db/mongodb.log --dbpath /nas/is1/bin/mongodb/data/db
about to fork child process, waiting until server is ready for connections.
