• run mongodb server

  cd mongodb-linux-x86_64-ubuntu1604-3.6.2/bin
  ./mongod --dbpath ../data/db
  

• create database and user

  cd mongodb-linux-x86_64-ubuntu1604-3.6.2/bin
  ./mongo
  use testdb
  db.createUser({user: "testuser", pwd: "secret", roles: [ "readWrite", "dbAdmin" ]}) 
  

• setup is complete. next time start mongodb with command

Just run Main in the project or see unit tests. Database server has to be started first.

gradle clean build distZip

cd mongodb-linux-x86_64-ubuntu1604-3.6.2/bin
./mongo
use testdb
db.roles.find()
db.roles.insert({"_id": "1", "description": "aaa" })
db.roles.remove({ "_id": "1" }, { justOne: true})
db.roles.drop()
