Python Data Persistence – Installation of MongoDB
MongoDB server software is available in two forms: Community edition (open source release) and Enterprise edition (having additional features such as administration, and monitoring).
The MongoDB community edition is available for Windows, Linux as well as MacOS operating systems at https://www.mongodb.com/ download-center/community. Choose the appropriate version as per the OS and architecture of your machine and install it as per the instructions on the official website. Examples in this chapter assume that MongoDB is installed on Windows in the e:\mongodb folder.
Start MongoDB server from command terminal using the following command:
E:\mongodb\bin>mongod . . . waiting for connections on port 27017
The server is now listening to connection requests from clients at port number 22017 of the localhost. (Server’s startup logs are omitted in the above display). To stop it, press ctrl-C. MongoDB databases are stored in the bin\data directory. You can specify alternative location though by specifying –dbpath option as follows:
- Data Persistence – Python – PyMongo
- Python Data Persistence – MongoDB – Update Document
- Python Data Persistence – PyMongo Module
Example
E:\mongodb\bin>mongod --dbpath e:\test
Now, start Mongo shell in another terminal.
E:\mongodb\bin>mongo
MongoDB shell version v4.0.6
connecting to:
mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb Implicit session:

Mongo shell is a Javascript interface to MongoDB server. It is similar to the SQLite shell or MsSQL console, as we have seen earlier chapter. The CRUD operations on the MongoDB database can be performed from here.
