Mangodb installation (Mac OS)

1. Download the corresponding version at http://www.mongodb.org/downloads

2. Create a folder structure such as/data/DB/in the root directory. By default, MongoDB stores data in this folder. Create a folder:

Sudo mkdir-P/data/DB

Modify folder permissions:

# Enter The sudo chmod 777 data directory of data # Enter The sudo chmod 777 dB directory of the database

3. decompress the downloaded file, put it in a specific directory, go to the MongoDB bin directory in the console, and enter:

./Mongod

If "dbexit: really exiting now" is displayed, the startup fails because the port is occupied or the/data/db operation permission is insufficient. If "waiting for connections on port 27017" is displayed, the instance is successfully started. You can enter http: // 127.0.0.1: 28017/in the browser to obtain the database management information.

4. Use shell to interact with MongoDB

Run on the console

./Mongo

Select database:

Use testdb
