MongoDB Package Components¶
On this page
Core Processes¶
The core components in the MongoDB package are: mongod, the core database process; mongos the controller and query router for sharded clusters; and mongo the interactive MongoDB Shell.
Windows Services¶
The mongod.exe and mongos.exe describe the options available for configuring MongoDB when running as a Windows Service. The mongod.exe and mongos.exe binaries provide a superset of the mongod and mongos options.
Binary Import and Export Tools¶
mongodump provides a method for creating BSON dump files from the mongod instances, while mongorestore makes it possible to restore these dumps. bsondump converts BSON dump files into JSON.
3.2 版后已移除: mongooplog
Data Import and Export Tools¶
mongoimport provides a method for taking data in JSON, CSV, or TSV and importing it into a mongod instance. mongoexport provides a method to export data from a mongod instance into JSON, CSV, or TSV.
注解
The conversion between BSON and other formats lacks full type fidelity. Therefore you cannot use mongoimport and mongoexport for round-trip import and export operations.
Diagnostic Tools¶
mongostat and mongotop provide diagnostic information related to the current operation of a mongod instance.
mongoreplay is a traffic capture and replay tool for MongoDB that you can use to inspect and record commands sent to a MongoDB instance, and then replay those commands back onto another host at a later time.
MongoDB 3.4 provides mongoldap for testing native operating system LDAP configuration options against a running LDAP server or set of servers.
