Create state database

We will use mongodb to store state and authentication data for our entity.

Install

Install direct from MongoDB's repo

sudo apt install dirmngr gnupg apt-transport-https ca-certificates software-properties-common
wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

sudo add-apt-repository 'deb [arch=amd64] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse'
sudo apt install mongodb-org
sudo systemctl enable --now mongod

Install using a docker container


Secure

create root user,

use admin
db.createUser({user:"koad", pwd:"PUT_MONGODB_ROOT_PASSWORD_HERE", roles:[{role:"root", db:"admin"}]})

From within mongo, authenticate as root

use admin
db.auth( "koad", "PUT_MONGODB_ROOT_PASSWORD_HERE")

Setup

Connect to dabrain's mongo instance as root

mongo --host 127.0.0.1 -u koad -p PUT_MONGODB_ROOT_PASSWORD_HERE --authenticationDatabase admin

Create a new database and user for some app somewhere

use seraph
db.createUser(
    {
      user: "seraph",
      pwd: "t7y3n0790xb7zr836f",
      roles: ["readWrite"]
    }
)

Maintain

Connect to the instance

mongo --host $MONGO_URL
See what is what (from within the mongo shell)
db.runCommand({connectionStatus : 1})

Restart the installed mongodb instance

sudo systemctl restart mongod

Restart the dockerizes mongodb instance


Utilize

Use this DB on some meteor app.. prefix the meteor command with

export DB_USER_NAME=PUT_YOUR_DB_USER_NAME_INFO_HERE
export DB_USER_PASS=PUT_YOUR_DB_USER_PASS_INFO_HERE
export DB_HOST=PUT_YOUR_DB_HOST_INFO_HERE
export DB_PORT=PUT_YOUR_DB_PORT_INFO_HERE
export DB_NAME=PUT_YOUR_DB_NAME_INFO_HERE
export MONGO_URL=mongodb://DB_USER_NAME:DB_USER_PASS@DB_HOST:DB_PORT/DB_NAME
