How To Install Mongodb On Aws Ec2

How to install and secure MongoDB in Amazon EC2 in minutes?

In this post, we will be installing MongoDB in Amazon EC2 example and secure it using authentication mechanism. The steps in the MongoDB site are not enough for a noob to complete the steps successfully. We volition first create an admin, who generally has root access to your database and then admin will create a user who tin can be created with specific roles and access to specific databases. The following process first adds a user administrator to a MongoDB case running without access command and then enables access command. This user can administer user and roles such as: create users, grant or revoke roles, and create or modify customs roles.

In this post, we will be installing MongoDB in Amazon EC2 case and secure it using authentication mechanism.

One comes to knows the importance of security only when he knows the importance of its task.

It is said to be that over 30% of MongoDB databases and its connections are not secured.

So don't you desire to secure information technology? Of course, anybody loves to secure whatsoever they host. Let's first implementing it.

The steps in the MongoDB site are not plenty for a noob to complete the steps successfully. This happened to me personally. After going through almost hundreds of post, I finally decided to document it perfectly because I know Sharing is Caring. If you find any difficulties in this post, feel gratis to comment. I will try to reply as soon every bit possible.

I assume you are already aware of Amazon Web services and petty knowledge on EC2. If you are not don't worry. I have created a tutorial about AWS(Amazon Web Services) and EC2 instance setup in the post-obit post. Request you lot to go through the same.

Let's install the MongoDB.

Once you are ready with the terminal, let's beginning installing MongoDB in information technology. Since we are going to ready this installation in minutes, I would asking yous to get through below link in the references section for the beneath-mentioned command for its detailed usages if yous need.

Stride 1: Import the public key used by the package management system.

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:lxxx --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5

Footstep 2: Create a list file for MongoDB. (for Ubuntu 16.04)

Step iii: Reload local parcel database.

Step four: Install the MongoDB packages.

sudo apt-get install -y mongodb-org

This volition install the latest stable version of MongoDB.

That'southward it, We have installed MongoDB latest stable version in our Amazon EC2 instance.

In the following procedure, Nosotros will first create an admin , who by and large has root admission to your database and then admin will create a user who can be created with specific roles and access to specific databases. Finally, we will be using user credentials to connect to our database and first working on it.

Let's start the MongoDB

Step one: Commencement MongoDB. Issue the following control to start mongod.

sudo service mongod start

Footstep 2: Verify that MongoDB has started successfully past typing the following command,

cat /var/log/mongodb/mongod.log

and ensure you find the beneath line at the last.

[initandlisten] waiting for connections on port 27017

That's it. You are successfully running MongoDB instance in your remote instance correct at present.

Annotation: Upshot the post-obit command to stop mongod (Don't execute till needed)

Note: Outcome the following command to restart mongod(Don't execute till needed)

sudo service mongod restart

Information technology's fourth dimension to secure your MongoDB.

Enabling access command on a MongoDB deployment enforces hallmark, requiring users to identify themselves. When accessing a MongoDB deployment that has access control enabled, users can only perform actions as determined by their roles.

The following procedure first adds a user administrator to a MongoDB case running without admission control and and then enables access control.

Access Control? — Aye, when you lot run the MongoDB with AccessControl, you lot are maxim, Offset secure MongoDB example.

admin — This user tin administrate user and roles such as: create users, grant or revoke roles from users, and create or modify customs roles.

Process

Step i: Create a directory to store data and set permission to information technology.

//Creating a path to store DB data.

//Giving yourself permission to write in that folder.
                  sudo chown $USER /data/db
              

If you take whatsoever difficulties in setting up this binder and permission, you may refer to this StackOverflow link.

Step 2: Showtime MongoDB without access control.

mongod --port 27017 --dbpath /data/db

Step 3: Let the MongoDB instance run on this terminal instance. Now permit's work on another remote terminal instance (Say Terminal 2) so that nosotros volition be switching to and fro later creating a user and to restart Mongo instance.

Open a new terminal and connect to your EC2 example. Now we volition be working on Mongo Beat out which is used to run commands or queries in your created database.

Now nosotros are going to create Mongo Shell by issuing the below command.

Now your concluding volition expect like a below paradigm, which is ready to run commands in it.

Mongo Shell

Step 4: Create the user administrator (admin)

In the admin database, add a user with the userAdminAnyDatabase function. This database acts as admin DB where nosotros creating it but for authentication purpose.

Result the following command to switch to admin DB even though you haven't created it. It will be created automatically when you consequence the control.

After switching to admin DB, allow's create an admin by issuing the following control.

db.createUser({user: "admin", pwd: "adminUser123", roles: [{function: "userAdminAnyDatabase", db: "admin"}]})

Which is prettified as, (Above prettified command, do non run twice)

db.createUser(
                {
                user: "admin",
                pwd: "adminUser123",
                roles: [ { part: "userAdminAnyDatabase", db: "admin" } ]
                }
)

Now you accept created an user called admin with userAdminAnyDatabase role.

Disconnect the mongo beat by pressing Ctrl+C.

Step 5: Switch dorsum to an old mongod case (Final 1) where it is running. Let'southward restart the MongoDB instance with access command to gain admin admission to our databases. Call up, you are starting your Mongo instance with admission control now.

Re-start the mongod case with the --auth control line option.

mongod --auth --port 27017 --dbpath /data/db

Stride half-dozen: Switch back to Last 2 (mongo beat example).

Connect and authenticate every bit the user administrator by issuing the below command.

mongo --port 27017 -u "admin" -p "adminUser123" --authenticationDatabase "admin"

Pace seven: Create additional users (user) as needed for your deployment.

Once authenticated as the user administrator, use db.createUser() to create additional users. You can assign any built-in roles or user-defined roles to the users. The following operation adds a user myTester to the test database who has a readWrite role in the test database

Consequence the post-obit command to create a database chosen examination and use it.

Now let'south create a user in this database, assigning specific roles to her/him.

db.createUser({user: "user", pwd: "user123", roles: [{part: "readWrite", db: "exam"}]})

Which is prettified as, (In a higher place prettified command, practice not run twice)

db.createUser(
                {
                user: "user",
                pwd: "user123",
                roles: [ { role: "readWrite", db: "test" } ]
                }
)

Now you have successfully created a user with specific roles and admission to database.

Step viii: Connect and authenticate as a user now.

Now, connect to the instance with the user function by issuing the following control in the same Mongo Crush.

mongo --port 27017 -u "user" -p "user123" --authenticationDatabase "exam"

You are now deeply authenticated as a user to the database chosen test. If you want to perform some query operations, you tin issue the below command and test at present.

db.foo.insert( { x: ane, y: 1 } )

Which creates a collection called foo and insert a same JSON in information technology.

Connect via Mongo URI connectedness string.

Below given the connectedness string needed to connect to this instance securely from your Node.js server, using mongoose module.

Yes. You have installed and configured your MongoDB deeply in your remote server. Permit's accept a interruption for a while.

In the next tutorial, permit united states utilize Docker and create an image and automate all this process so that just a Docker prototype is required to install and secure MongoDB in any instance in a single command.

Cheers.
