MongoDb - Projeto Final

Autor: Lucas da Silva Moreira

Data: 1456674804092

Para qual sistema você usaria o MogoDB (diferente desse)?

  • Chat
  • ERP
  • Sistemas de CRUD
  • Sistemas que eu tenha que mostrar várias informações de uma vez

Qual a modelagem da sua coleção de users?

user: {
	id_user: ObjectId,
	name: String,
	bio: String,
	date_register: Date,
	avatar_path: String,
	background_path: String,

	auth: {
		username: String,
		email: String,
		password: String,
		last_acess: Date,
		online: Boolean,
		disabled: Boolean,
		hash-token: String
	}
}

Qual a modelagem da sua coleção de projects?

project: {
  "id": ObjectId
  "name": String
  "description": String
  "date_begin": Date(),
  "date_dream": Date(),
  "date_end": Date(),
  "visible": boolean
  "realocate": boolean,
  "expired": boolean,
  "visualizable_mod": String
  "tags": [],
  "goals": [
    {
      "name": String
      "description": String,
      "date_begin": Date(),
      "date_dream": Date(),
      "date_end": Date(),
      "realocate": boolean
      "expired": boolean
      "tags": [],
      "historic": {
        "date_realocate": Date()
      },
      "activities": [
        {
          "activity_id": ObjectId
        }
      ]
    }
  ],
  "members": [
    {
      "id_user": ObjectId,
      "notify": String
      "type": String
    }
  ]
}

Qual a modelagem da sua coleção retirada de projects?

activity: {
	name: String
	description: String
	date_begin: Date(),
	date_dream: Date(),
	date_end: Date(),
	realocate: false,
	expired: false,

	historic: {
		date_realocate: Date()
	},

	tags: [],

	members: [{
		id_user: ObjectId,
		notify: String,
		type: String,
	}],

	comments: [{
		members: [{
			id_user: ObjectId,
			notify: String,
			type: String,
		}],
        text: String,
        date_comment: Date(),
        files: [{
			path: String,
			weight: String,
			name: String
		}]				
	}]
}

Motivo

Separei a coleção activities da coleção projects porque um projeto pode ter várias atividades, e como uma atividade pode se tornar uma coleção grande, resolvi separar e não carregá-la desnecessariamente toda vez que a coleção projects for buscada.

Create - cadastro

1. Cadastre 10 usuários diferentes.

var users = [

	{name: "Silvana Jordão", username: "silvana_jordao"},
	{name: "Virgínia Remígio", username: "virginia_remigio"}	
]

var usersList = []

users.forEach(function(user) {
	var query = {

			hash_token: "698dc19d489c4e4db73e28a713eab07b"+user.username.length
		}
	}
	usersList.push(query)
})

db.users.insert(usersList)

Inserted 1 record(s) in 553ms

  "nUpserted": 0,

2. Cadastre 5 projetos diferentes.

  • cada um com 5 membros, sempre diferentes dentro dos projetos;
  • cada um com pelo menos 3 tags diferentes;
    • escolha 1 tag onde deva ficar em 2 projetos;
    • escolha 1 tag onde deva ficar em 3 projetos;
  • cada projeto com pelo menos 1 goal;
    • cada goal com pelo menos 3 tags;
    • cada goal com pelo menos 2 atividades, deixe 1 projeto sem.

// Salvando duas atividades para referenciar nos projetos

for (var i = 1; i <= 2; i++) {
	db.activities.insert({

Gerenciamento de usuários

1. Crie um usuário com permissões APENAS de Leitura.

db.createUser(
  {
    user: "ReadUser",
    pwd: "read123",
    roles: [ { role: "read", db: "projeto_final" } ]
  }
)

Successfully added user: {
  "user": "ReadUser",
  "roles": [
    {
      "role": "read",
      "db": "projeto_final"
    }
  ]
}

2. Crie um usuário com permissões de Escrita e Leitura.

db.createUser(
  {
    user: "ReadWriteUser",
    pwd: "readWrite123",
    roles: [ { role: "readWrite", db: "projeto_final" } ]
  }
)

Successfully added user: {
  "user": "ReadWriteUser",
  "roles": [
    {
      "role": "readWrite",
      "db": "projeto_final"
    }

3. Adicionar o papel grantRolesToUser e revokeRole para o usuário com Escrita e Leitura.

db.createRole(
   {
     role: "grantRolesToUser",
     privileges: [
       { resource: { db: "projeto_final", collection: "" }, actions: [ "grantRole" ] }

     role: "revokeRole",
     privileges: [
       { resource: { db: "projeto_final", collection: "" }, actions: [ "revokeRole" ] }

    {
      "resource": {
        "db": "projeto_final",
        "collection": ""
      },
      "actions": [
        "revokeRole"
      ]
    }
  ],
  "roles": [ ]
}

db.grantRolesToUser(
    "ReadWriteUser",
    [
      "grantRolesToUser", "revokeRole"
    ]
)

4. Remover o papel grantRolesToUser para o usuário com Escrita e Leitura.

db.revokeRolesFromUser(
    "ReadWriteUser",
    [
      { role: "grantRolesToUser", db: "projeto_final" }
    ]
)

5. Listar todos os usuários com seus papéis e ações.

db.getUsers()
[
  {
    "_id": "projeto_final.ReadUser",
    "user": "ReadUser",
    "db": "projeto_final",
    "roles": [
      {
        "role": "read",
        "db": "projeto_final"
      }
    ]
  },
  {
    "_id": "projeto_final.ReadWriteUser",
    "user": "ReadWriteUser",
    "db": "projeto_final",
    "roles": [
      {
        "role": "revokeRole",
        "db": "projeto_final"
      },
      {
        "role": "readWrite",
        "db": "projeto_final"
      }
    ]
  }
]

Cluster

Depois de criada toda sua base você deverá criar um cluster utilizando: 1 Router, 1 Config Server, 3 Shardings e 3 Replicas

Criando o Config Server

mkdir data/configdb
mongod --configsvr --port 27010

Criando o Router

mongos --configdb localhost:27010 --port 27011

Criando os Shards

mkdir data/shard1
mkdir data/shard2
mkdir data/shard3

mongod --port 27012 --dbpath data/shard1
mongod --port 27013 --dbpath data/shard2
mongod --port 27014 --dbpath data/shard3

Registrando os Shards no Router

MacBook-Pro-de-Lucas:data lucasmoreira$ mongo --port 27011 --host localhost
MongoDB shell version: 3.2.0
connecting to: localhost:27011/test
Mongo-Hacker 0.0.9
MacBook-Pro-de-Lucas(mongos-3.2.0)[mongos] test> sh.addShard("localhost:27012")
{
  "shardAdded": "shard0000",
  "ok": 1
}
MacBook-Pro-de-Lucas(mongos-3.2.0)[mongos] test> sh.addShard("localhost:27013")
{
  "shardAdded": "shard0001",
  "ok": 1
}
MacBook-Pro-de-Lucas(mongos-3.2.0)[mongos] test> sh.addShard("localhost:27014")
{
  "shardAdded": "shard0002",
  "ok": 1
}

Especificamos qual database iremos shardear:

sh.enableSharding("be-mean")
{
  "ok": 1
}

E depois especificamos qual coleção dessa database será shardeada com sh.shardCollection:

sh.shardCollection("be-mean.notas", {"_id" : 1})
{
  "collectionsharded": "be-mean.notas",
  "ok": 1
}

Réplicas

Criação das pastas para armazenamento das réplicas:

mkdir data/rs1
mkdir data/rs2
mkdir data/rs3

Iniciando os processos do mongod com replSet, da seguinte forma:

mongod --replSet replica_set --port 27017 --dbpath data/rs1
