MongoDB Learning Summary (i) installation under--windows platform

I. Basic CONCEPTS

MongoDB is an open source database system based on distributed file storage that provides scalable , high-performance data storage solutions for WEB applications. MongoDB stores data as a document and data structures consist of key-value key=>value . The document resembles a JSON object. Field values can contain other documents, arrays, and array of documents.

several basic concepts of MongoDB database:

1) in a MongoDB instance, there can be 0 or more database ( databases ).

2) There can be 0 or more collections (collections) in a database . is equivalent to a table ( table )in a traditional relational database.

3) A collection consists of 0 or more documents . Corresponds to row in a table in a traditional relational database .

4) The document consists of 0 or more fields. equivalent to the columns in a table in atraditional relational database.

Two. installing under Windows Platform

1. Download MongoDB file

MongoDB provides. msi files and. zip files available for both 32-bit and 64-bit systems , where i download the . zip file for the system .

: Http://www.mongodb.org/downloads

Here I test using a 32-bit version, it is important to note that the MongoDB database on the system is a maximum of 2GB.

Unzip the downloaded file and place it where you want it. I put it under the D:\MyProject\mongodb and Create a new folder , DB, to store the MongoDB data.

2. Start MongoDB Service

run cmd into the program directory bin , run the mongod Start command,--dbpath Specify the data to save the directory.

It is important to note that after the MongoDB service is turned on, the command-line window cannot be closed and the MongoDB service shuts down as soon as it is closed. As a result, we will typically change it to a Windows service and set it to boot automatically.

run cmd into the program Directory bin , run the following command.

Parameter description:

--LOGPATH Specifies the MongoDB log file, note that the file is not a directory.

--logappend logs are logged using the Append method.

--DBPATH Specifies the database path.

--directoryperdb creates a new directory per db.

--SERVICENAME Specifies the service name.

--SERVICEDISPLAYNAME Specifies the service display name.

--install is specified as a Windows service installation.

The following error occurred while running the above command:

The system needs to add the --journal parameter according to the error .

The service was created successfully, but could not be started, viewing the log display

Requested option conflicts with current storage engine option for DIRECTORYPERDB;

You requested true if the current server storage are already set to false and cannot be changed, terminating

2016-09-18t10:16:08.366+0800 I CONTROL [Servicestopworker] dbexit:rc:49

The hint indicates that the current server storage cannot be changed, and the--DIRECTORYPERDB parameter needs to be removed.

The service starts successfully at this time.

These are some of the errors and workarounds that I encountered when I created the Windows service.

3. Start the MongoDB client

We also open a cmd window, run the MONGO command opened the shell, theequivalent of MongoDB client .

We see that the client connection was successful.

Installation and launch under the Windows platform is here, and next we'll cover some of the basic operations commands for MongoDB.
