In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Configuration:

Common configurations are as follows:

Configuration example

Net: port: 27017 # # listening port systemLog: destination: file path: "mongod.log" # # Log file storage location logAppend: true # # additional mode write log storage: engine: wiredTiger # # data engine type, highly recommended wiredTiger dbPath: / data/soft/mongodb-3.2.1/data # # data storage location journal: enabled: true # # production environment is highly recommended to open wiredTiger: engineConfig: cacheSizeGB: 2 # engine cache size, version 3.4 starting The default value is: (half of memory-1G) or 256m, take the maximum statisticsLogDelaySecs: 3600 # # log refresh interval journalCompressor: snappy # # journal compression, allowed values: none,snappy,zlib directoryForIndexes: false # # subdirectory storage index and data collectionConfig: blockCompressor: snappy # # data file compression, allowed values: none,snappy,zlibprocessManagement: fork: true # # database process replication: oplogSizeMB: 2048 # # replica set operation log size The higher the value, the more downtime is allowed, otherwise the downtime of a machine is too large It will cause the data that exceeds the size of the operation log to fail to synchronize replSetName: candao_release # # replica set name sharding: clusterRole: shardsvr # # identity in the shard cluster security: keyFile: / data/soft/mongodb-3.2.1/mongo-key # # Security key file used for communication between clusters clusterAuthMode: "keyFile" # # Cluster authentication mode authorization: "enabled" # # whether to enable user authentication "MongoDB often" This is the end of the content of "using configuration and maintenance methods" Thank you for your reading.
