MongoDBは例外エラーのために閉じられ、修正されました

Mongodb Start Closed

1つのエラー：

[ftdc] Unclean full-time diagnostic data capture shutdown detected, found interim file, some metrics may have been lost.

解決：

1、診断データを削除します。

rm -f /var/lib/mongo/diagnostic.data/*

2、mongodbを開始します。

MongoDBのbinディレクトリに、

sudo ./mongod

2エラー：

2018-07-20T22:42:08.645+0800 I STORAGE [initandlisten] exception in initAndListen: DBPathInUse: Unable to lock the lock file: (Unknown error). Another mongod instance is already running on the /data/db directory, terminating. 2018-07-20T22:42:08.645+0800 I CONTROL [initandlisten] now exiting 2018-07-20T22:42:08.645+0800 I CONTROL [initandlisten] shutting down with code:100

解決策：mongodbが不適切に削除されたファイルを閉じるとmongod.lockが発生する可能性があります（ロックファイルのパスは異なります）。

sudo rm /data/db/mongod.lock

間違い3：

2018-07-20T22:29:17.982+0800 I CONTROL [initandlisten] MongoDB starting : pid=3499 port=27017 dbpath=/data/db 64-bit host=xumovm ...... 2018-07-20T21:12:05.974+0800 E STORAGE [initandlisten] Failed to set up listener: SocketException: Address already in use

解決：

mongoを見つける前に実行されているPID番号をオフにして、コマンドの再入力を開始します

sudo netstat -anp|more Activate Internet Connection (servers and established connections) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 2515/./mongod sudo kill 2515

正しいクローズ：Mongodbを停止します

方法1：プロセスを表示し、kill-9を使用できないkillコマンドを使用します

方法2：のクライアントで、shutdownコマンドを使用します

1、新しくインストールされたmongodbは、sudo service mongod start（sudo service mongod restart）を実行し、開始に失敗したと報告しています。

解決手順：

1, delete the log files /var/log/mongodb/mongod.log

rm /var/log/mongodb/mongod.log

2, delete the lock file

rm /var/log/mongodb/mongod.log

3, execute repair

sudo / usr / bin / mongod –repair –dbpath / var / lib / mongodb / –repairpath / tmp / mongodb

4-最後の方法：サーバーを再起動します

reboot
