MongoDB database installation notes

1, the database (Database)

按照数据结构来组织、存储和管理数据的仓库。

2, the database classification:

• Relational database (the RDBMS)
  · MySQL, the Oracle, the DB2, SQL Server ...
  · full table
• Non-relational databases (SQL No)
  · MongoDB, Redis ...
  · key-value database
  -document database MongoDB

3、MOngoDB

• Minimalist, flexible, as part of the Web application stack, MongoDB is a document-oriented data model, is a structure similar to JSON. (BSON)
• 下载MongoDB：https://www.mongodb.org/dl/win32/

4, install MongoDB

• 1, the installation
• 2, configure the environment variables
  • Path (to bin) MongoDB added to the installation environment variable (path)
• 3. Verify that the installation was successful
  • Open the CMD, enter mongod
• 4, in the root directory of C
  • Create a folder data
  • Create a data file in the folder db (default directory MongoDB database)
• 5, open CMD command window
  • Enter mongod start MongoDB server
  • Note: 32-bit system when you first start the MongoDB database, the command is: mongod --storageEngine = mmapv1
• 6, and then open a CMD window
  • Input connection mongo MongoDB, show: connecting to: test indicates a successful connection MongoDB database. Appears>
• 7, starts MongoDB database and set the database path (this database may be set to any position of the path, instead of the default data db in the C drive)
  • Open the CMD, enter the command: mongod --dbpath path
• 8, start the MongoDB database, the default port is 27017, can be modified through the command port
  • Open the CMD, enter the command: mongod --port port number
  • Would set a good database path port number: mongod --dbpath path --port port number
  • Best to use the default port number, not more than 1,000 minimum, maximum not more than 65,535
• 9, database (database)
  • Server database
    • Server used to store data
    • mongod used to start the server
  • Client database
    • Client to a server operation, the data CRUD operations.
    • mongo used to start the client
• 10, MongoDB will be set as a system service, you can start automatically in the background, you do not need to manually start each time.
  • (1) create data in the root directory of C (not necessarily the path to the database in the C drive, as already explained)
    • Creating folders db and log in data
  • (2) create a configuration file
    • Adding a configuration file in the installation directory (the same bin at the same level) mongod.cfg
    • Within mongod.cfg file path is subject to its own path
    • mongod.cfg configuration file as follows:

systemLog:  		 
	Destination: file 
	Path: c:\data\log\mongod.log 
storage: 
	dbPath: c:\data\db

• (3) Open a command window as an administrator
  

• (4) Run the following command (whichever path has its own installation path):

sc.exe create MongoDB binPath="\"C:\Program Files\MongoDB\Server\3.4\bin\mongod.exe\" --service --config=\"C:\Program Files\MongoDB\Server\3.4\mongod.cfg\"" DisplayName= "MongoDB" start= "auto"

• (5) start the MongoDB service
  • Right-open the Task Manager, click on "Services" all services open to view, find MongoDB, right-click "start"
• (6) If the startup fails to prove that on top of a mistake
  • In the console enter service configuration before you remove the sc delete MongoDB
  • And then again from the first step
