Setup MongoDB Server on ARM64 using Scaleway

I've been using Scaleway for the past 18 months and I must admit, I love hosting my Applications on their Infrastructure. They have expanded rapidly recently, and currently deploying more infrstructure due to the high demand.

Scaleway is a Cloud Division of Online.net. They provide Baremetal and Cloud SSD Virtual Servers. Im currently hosting a Docker Swarm Cluster, Blogs, Payara Java Application Servers, Elasticsearch and MongoDB Clusters with them and really happy with the performance and stability of their services.

What will we be doing today:

Today I will be deploying MongoDB Server on a ARM64-2GB Instance, which costs you 2.99 Euros per month, absolutely awesome pricing! After we install MongoDB we will setup authentication, and then just a few basic examples on writing and reading from MongoDB.

Getting Started:

Logon to cloud.scaleway.com then launch an instance, which will look like the following:

After you deployed your instance, SSH to your instance, and it should look like this:

Dependencies:

Get the repository and install MongoDB:

$ apt update
$ 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
$ apt update && apt upgrade -y
$ apt install mongodb-org -y

Enable MongoDB on Boot:

$ systemctl enable mongod

Configuration:

Your configuration might look different from mine, so I recommend to backup your config first, as the following command will overwrite the config to the configuration that I will be using for this demonstration:

$ cat > /etc/mongod.conf << EOF
storage:
  dbPath: /var/lib/mongodb
  journal:
    enabled: false

storage:
  mmapv1:
    smallFiles: true

systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

net:
  port: 27017
  bindIp: 0.0.0.0

processManagement:
  timeZoneInfo: /usr/share/zoneinfo

security:
  authorization: enabled
EOF

Restart MongoDB for the config changes to take affect:

$ systemctl restart mongod

Authentication:

Create the Authentication:

$ mongo
MongoDB shell version v3.6.3
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.6.3
Welcome to the MongoDB shell.

> use admin
> db.createUser({user: "ruan", pwd: "pass123", roles:[{role: "root", db: "admin"}]})
Successfully added user: {
        "user" : "ruan",
        "roles" : [
                {
                        "role" : "root",
                        "db" : "admin"
                }
        ]
}

> exit

Restart MongoDB and logon with your credentials:

$ systemctl restart mongod

$ mongo --authenticationDatabase admin --host localhost --port 27017 -u ruan -p
MongoDB shell version v3.6.3
Enter password:
connecting to: mongodb://localhost:27017/
MongoDB server version: 3.6.3

Write and Read from MongoDB

While you are on the MongoDB Shell, we will insert a couple of documents, first drop in to the database that you would like to write to:

> use testdb
switched to db testdb

Now we will write to the collection: collection1:

> db.collection1.insert({"name": "ruan", "surname": "bekker", "age": 31, "country": "south africa"})
WriteResult({ "nInserted" : 1 })

> db.collection1.insert({"name": "stefan", "surname": "bester", "age": 30, "country": "south africa"})
WriteResult({ "nInserted" : 1 })

To find all the documents in our collection:

> db.collection1.find()
{ "_id" : ObjectId("5ac15ff0f4a5500484defd23"), "name" : "ruan", "surname" : "bekker", "age" : 31, "country" : "south africa" }
{ "_id" : ObjectId("5ac16003f4a5500484defd24"), "name" : "stefan", "surname" : "bester", "age" : 30, "country" : "south africa" }

To prettify the output:

> db.collection1.find().pretty()
{
        "_id" : ObjectId("5ac15ff0f4a5500484defd23"),
        "name" : "ruan",
        "surname" : "bekker",
        "age" : 31,
        "country" : "south africa"
}
{
        "_id" : ObjectId("5ac16003f4a5500484defd24"),
        "name" : "stefan",
        "surname" : "bester",
        "age" : 30,
        "country" : "south africa"
}

To find a document with the key/value of name: ruan:

> db.collection1.find({"name": "ruan"}).pretty()
{
        "_id" : ObjectId("5ac15ff0f4a5500484defd23"),
        "name" : "ruan",
        "surname" : "bekker",
        "age" : 31,
        "country" : "south africa"
}

To view the database that you are currently switched to:

> db
testdb

To view all the databases:

> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB
testdb  0.000GB

To view the collections in the database:

> show collections
collection1

> exit
