MongoDB Installation Tutorials

Preface:

MongoDB is a database based on distributed file storage. Designed by C + + to provide scalable, high-performance data storage solutions for Web applications.

Official website: https://www.mongodb.com/

This tutorial is only for Windows systems

Step one: Download MongoDB

Address: http://dl.mongodb.org/dl/win32/x86_64

Download Mongodb-win32-x86_64-2008plus-ssl-v3.4-latest.zip here and unzip it in D:\mongodb (where the path can be chosen by itself) as shown in:

Step Two: Create a folder db, log

Create your own folders d:\mongodb\data\db, D:\mongodb\data\log, respectively, to install the DB and log files.

Step three: command-line installation

Run cmd.exe into the DOS command interface and execute the following command

>> CD D:\mongodb\bin

> >>d:\mongodb\bin>mongod-dbpath=d:\mongodb\data\db

The default MongoDB listener port is 27017,mysql 3306

Step Four: Verifying the installation

DOS command interface, after the installation is complete, open http://127.0.0.1:27017/, see the following prompt, indicating that the installation was successful.

Step five: Set MongoDB as a Windows service

Every time I want to use the MongoDB database to open the Mongod.exe program, so it is more troublesome, at this time we can install MongoDB as a Windows service

DOS command interface, execute the following command:

>> CD D:\mongodb\bin

>>mongod--dbpath "d:\mongodb\data\db"--logpath "D:\mongodb\data\log\MongoDB.log"--install--servicename " MongoDB "

Where MongoDB.log is the log file that was started,--servicename the "MongoDB" service named MongoDB

We can see the MongoDB created on the Windows Services page.

Step Six: Start the MongoDB service

DOS command interface, execute the following command:

NET START MongoDB

Step Seven: Open the MongoDB shell

DOS command interface, execute the following command: MONGO, open the shell, in fact, the shell is the client of MongoDB

Step Eight: Close the service and delete the process

DOS command interface, execute the following command:

>> netstop MongoDB (off service)

>> mongod--dbpath "d:\mongodb\data\db"--logpath "D:\mongodb\data\log\MongoDB.log"--remove--servicename " MongoDB "(Delete, note not--install)

Step nine: MongoDB common commands

1. Common commands

Show DBS Display Database list

Use dbname Enter dbname database, case sensitive

Show Collections displays a collection in the database, equivalent to a table

2. Create & Add

Db.users.save ({"Name": "Jack"}) created a collection named users and added a new {"Name": "LECAF"} data

Db.users.insert ({"Name": "Jack", "Age": 20}) Inserts a new data into the Users collection, and if there is no users this collection, MongoDB automatically creates

3. Delete

Db.users.remove () Delete all data under the Users collection

Db.users.remove ({"Name": "Jack"}) delete Name=jack data under the Users collection

Db.users.drop () or Db.runcommand ({"Drop", "users"}) Delete collection users

Db.runcommand ({"Dropdatabase": 1}) Delete the current database

4. Find

Db.users.find () Find all data in the Users collection

Db.users.findOne () to find the first data in the Users collection

5. Modifications

Db.users.update ({"Name": "Jack"}, {"Age": 50}) Modify the Name=jack data to age=50

The first parameter is the lookup condition, the second parameter is the modification, except the primary key, the other content is replaced by the contents of the second parameter, the primary key cannot be modified.
