===Debian/Ubuntu===
https://git.charlesreid1.com/docker/d-mongoexpress


MongoDB provides instructions for installing on Debian/Ubuntu. The short version: don't do <code>apt-get install mongodb</code>.
=Summary=


Here's what you do:
The brief summary:
* Add the mongodb aptitude repositories to your aptitude
* MongoDB provides a nosql unstructured data store for arbitrarily complicated json structures
* Update your aptitude
* Listens on port 27017
* Install a mongodb package from mongodb.org
* Install from mongodb.org debian repos
* Config handles file paths, logging, security, networking
* Multiple ways to interface (command line shell in Javascript, or via language bindings)
* Users must be created per-database, or a system-wide admin account added
* Enable user access controls, expose to private management LAN interfaces

=Installing=
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list
sudo apt-get update
sudo apt-get install -y mongodb-org
</pre>


These assume you have ubuntu xenial, see link [https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/] for other LTS releases.

To run MongoDB using Docker, I recommend using a docker-pod that has both MongoDB and MongoExpress (web frontend for MongoDB).

MongoDB offers two access control mechanisms: user authentication, and network access.


Reset with Mongodb, now August 2016, here's what we're doing:
First, MongoDB allows you to create an admin user, which can be used to create various user accounts with different permissions levels for different data. This provides a fine-grained access control mechanism around MongoDB.

Second, like any network service, MongoDB can bind to a particular network interface, allowing the network firewall to be used to restrict access to MongoDB.

  • Listens on port 27017
  • Install from mongodb.org debian repos
  • Config handles file paths, logging, security, networking
  • Multiple ways to interface (command line shell in Javascript, or via language bindings)
  • Users must be created per-database, or a system-wide admin account added

Access Control

MongoDB offers two access control mechanisms: user authentication, and network access.

First, MongoDB allows you to create an admin user, which can be used to create various user accounts with different permissions levels for different data. This provides a fine-grained access control mechanism around MongoDB.

Basic CRUD Operations

MongoDB performs CRUD (create, read, update, delete) transactions/operations on the data that it stores.

Monitoring

MongoDB as a Monitoring Target

MongoDB has several mechanisms for monitoring the state of the database (per second operations, cache sizes, disk and memory usage, etc.)

Utilities like Netdata and Collectd have plugins written for MongoDB that can collect this information as part of scraping the system status.

MongoDB as a Monitoring Data Store

collectd has a Write_MongoDB plugin to allow collectd to write its data to MongoDB.

Plugin link: https://collectd.org/wiki/index.php/Plugin:Write_MongoDB

APIs

Python API: Pymongo

Java API: MongoDB/Java
