Introduction to MongoDB, installation and configuration
1. It is written in C++ language and is an open source database system based on distributed file storage.
2.mongodb: a database stored in a key-value manner. As a NoSQL database, transaction management is not supported.
3. Access rights can be set for each database, and there is an admin database for saving relevant data for managing user rights.
4. Some collections may need to have data in it to display the collection name.
5. Comparing with mySql
Database --> Database Collection --> Data Table document --> a record Data Fields --> Data Fields
MongoDB installation software:

MongoDB visual management software: Robomongo.exe
MongoDB installation configuration
1. Install MongoDB software
2. Establish such a directory path C:\mongodb \data\db\, \C:\mongodb\data\log\mongo.log, C:\mongodb\data\mongo.config
3.mongo.config content:
##data files dbpath=C:\mongodb\data\db ## log file logpath=C:\mongodb\data\log\mongo.log
4. CDM command window: cd "c:\Program Files\MongoDB\Server\3.2\bin"
5. CDM command window: mongod.exe --config c:\mongodb\data\mongo.config --install
6. Then You can view the service list of the system, run "services.msc", open the system service management interface and find the "Mongodb" service in it, and verify that the above operation has indeed successfully injected the Mongodb service into the system;
7. Start the service, and it will be successful in Windows The MongoDB service is created below, so you don't have to see the annoying command service terminal in the future.
Test
: 1. CDM command window: cd "c:\Program Files\MongoDB\Server\3.2\bin"
2. CDM command window: mongo
3. CDM command window: use testDB //Create a testDB database
4.CDM command window: db.testCollection.insert({"name":"Rookie Tutorial"}) //Add the testCollection collection (if not) to the testDB database, and send the Add {"name":"Rookie Tutorial"} data
to the testCollection collection 5.CDM command window: db.testCollection.find() //View all data in the testCollection collection
MongoDB set access permissions and set users
1.use admin
2.db.createUser({user: "admin",pwd: "admin",roles: [ { role: "root", db: "admin" } ]}) //Add user admin, with the highest root privilege ( User management and database operations), db represents a database that can be accessed, but the highest authority is not limited by this.
3. Enter the system registry (WIN+R-->regedit), find [HKEY_LOCAL_MACHINE-->SYSTEM-- >CurrentControlSet-->Services-->MongoDB] Hit "ImagePath" in the key-value list on the right
[url] "c:\Program Files\MongoDB\Server\3.2\bin\mongod.exe" --config c :\mongodb\data\mongo.config --service changed to
"c:\Program Files\MongoDB\Server\3.2\bin\mongod.exe" --config c:\mongodb\data\mongo.config -auth -- service[/url]
4.mongo
5.use admin
6.db.auth("admin","admin")
7.show collections
8. It is also possible to go to other databases for operation, because it is root privileges.
9. Before creating a new user authority, it is best to clear the user configuration that comes with the system.
