My MongoDB notes

MongoDB is a general purpose, document-based, distributed database built for modern application developers and for the cloud era.

install

Install and run MongoDB Community Edition on Ubuntu 18.04 LTS

The site has excellent documentation so I am simply providing overview of steps.

1. Import the public key used by the package management system.
2. Create a list file for MongoDB.
3. Reload local package database.
4. Install the MongoDB packages.

Run MongoDB Community Edition

1. Start MongoDB with sudo service mongod start
2. Verify that MongoDB has started successfully with sudo grep port /var/log/mongodb/mongod.log or sudo service mongod status
3. Stop MongoDB with sudo service mongod stop
4. Restart MongoDB with sudo service mongod restart
5. Begin using MongoDB shell with mongo

Verify MongoDB starts on Ubuntu 18.04 start up (MongoDB Community Edition default install does not start on Ubuntu 18.04 startup)

$ sudo systemctl list-unit-files | grep mongod
mongod.service                             enabled  <--- If this value is not enabled, run below command to activate.

Configure MongoDB to start on Ubuntu 18.04 start up

$ sudo systemctl enable mongod.service
Created symlink /etc/systemd/system/multi-user.target.wants/mongod.service → /lib/systemd/system/mongod.service.

Running mongo shell for first time

$ mongo

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

Windows 10 (dev environment)

Download MongoDB Community Edition zip package

Extract downloaded file and rename to root directory to mongodb.

Move mongodb directory to user profile. On my Windows 10 dev machine the absolute path is C:\Users\anon\mongodb.

Create directory in same profile that will hold mongodb collections called mongodb-data. The absolute path is C:\Users\anon\mongodb-db.

To run MongoDB open shell in C:\Users\anon\mongodb\bin directory and type .\mongod.exe --dbpath=\Users\anon\mongodb-data\
