Install MongoDB Community Edition

Install MongoDB Database using CentOS Package Installation Manager – yum. First, you need to create a file /etc/yum.repos.d/mongodb-org-4.4.repo for this database

# nano /etc/yum.repos.d/mongodb-org-4.4.repo

Then paste into your text editor what is described below:

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

Save this and then you can close your text editor. After that, if you want to install the latest, stable and current version of MongoDB, you need to enter the following:

# sudo yum install -y mongodb-org

Configuring MongoDB

At this stage, the installation of this Database is completed. Now you need to configure it. To do this, you must first start MongoDB

# systemctl start mongod.service
# systemctl enable mongod.service

Next, connect to MongoDB

# mongo

MongoDB is insecure by default. You can follow this link to configure security and authentication of this Database.

If you need to install a specific version or prevent automatic updates, you can see the MongoDB documentation.

Update the package repository

\Before installing MongoDB, you need to make sure everything is up to date. This can be done by running the following command accordingly:

pkg update

There may be the following message stating that “package management tool” is not available, type Y, press Enter to continue. You can run pkg update -f a forced update if needed. If unsuccessful, go to step 2 – Installing MongoDB

Installing MongoDB

Install MongoDB using the following command:

pkg install mongodb

Start and Test The Installation of MongoDB

Check your MongoDB installation. This command will start the service:

service mongod onestart

The consol’ll look loke this:

MongoDB shell version: 4.4
connecting to: test
Welcome to the MongoDB shell.
For interactive help, type "help".

Turn the MongoDB at each boot

If you don’t want to use “onestart” to start Mongo on boot, you can configure it to run start instead. To do this, you need to edit /etc/rc.conf. with vi or any other text editor and add mongod_enable = “YES” to the file. Once finished, it will start when your server boots up and you can now use its service mongod start to start the Mongo service. Other service commands such as stop and status will also be available.

Add MongoDB Public Key

This command adds the GPG MongoDB public key to the system key list:

apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

This key is necessary in order to ensure the consistency and authenticity of all packages.

Add MongoDB Storage

First you need to create the mongodb.list file to add the MongoDB repository to the system. You can do this with the following command:

echo "deb http://repo.mongodb.org/apt/debian "$(lsb_release -sc)"/mongodb-org/3.0 main" | tee /etc/apt/sources.list.d/mongodb-org-3.0.list

Package Updates

To get information about the latest packages, please nter the command:

apt-get update

Install MongoDB packages

To install the latest stable version of MongoDB, use the following command:

apt-get install -y mongodb-org

• mongodb-org-server
• mongodb-org-mongos
• mongodb-org-shell
• mongodb-org-tools

*Here are 4 packages that mongodb-org automatically install

Launch MongoDB

After installation is complete, MongoDB starts automatically. If you need to manually start the MongoDB server, use the following command:

service mongod start

To stop and restart mongodb processes, use this commands:

service mongod stop

service mongod restart

You can access the MongoDB shell by running the following command: (this allows you to connect to the MongoDB server)

mongo

When the shell starts, you will see the output in the following format:

MongoDB shell version: 3.0.0
connecting to: test
>

Add MongoDB Public Key

The command below adds the MongoDB public GPG key to the set of all other system keys. Debian’s package management tools need this key to ensure consistency and authenticity of packages.

apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

Add MongoDB Repository

First, you need to create a mongodb.list file to add the MongoDB repository to your system. This command, which is described below, will give you the opportunity to create the required file:

echo "deb http://repo.mongodb.org/apt/debian "$(lsb_release -sc)"/mongodb-org/3.0 main" | tee /etc/apt/sources.list.d/mongodb-org-3.0.list

Update packages

Use the command below to get complete information about the latest packages in the repositories:

apt-get update

Install MongoDB packages

To install the latest stable version of MongoDB, use the following command, which is provided below:

apt-get install -y mongodb-org

mongodb-org is a “metapackage” that automatically installs four component packages:

• mongodb-org-server
• mongodb-org-mongos
• mongodb-org-shell
• mongodb-org-tools

Start MongoDB

After the installation isfinished, MongoDB will be started immediately. If you need to manually run the MongoDB server, then use the following command:

service mongodb start

To stop the mongodb process, use this command:

service mongodb stop

And to restart mongodb, use the following:

service mongodb restart

The MongoDB shell can be accessed by running the following command. This allows you to connect to the MongoDB server.

mongo

When the shell is launched, you will see output in this format:

MongoDB shell version: 3.0.0
connecting to: test
>

Now you can use MongoDB on your Debian server.

Start your Mongo client first. On Linux, this is the mongo command. Enter this block of text, of course, changing the parts of the placeholder to your own information.

The protection procedure begins with the fact that you need to start your Mongo client. On Linux, this is the mongo command. Enter this block of text, of course, changing the parts of the placeholder to your own information.

db.createUser({
  user: "USERNAME", 
  pwd: "PASSWORD", 
  roles: [
    {
      role: "readWrite",
      db: "YOUR_DATABASE"
    }
  ]
});

Next, you need to exit the mongo client and edit the MongoDB configuration file. Depending on your OS and distribution, you will find it in one of these places.

/etc/mongodb.conf
/etc/mongod.conf

Change the following #security: line to the following:

security:
  authorization: enabled

You should consider changing the bind port to localhost (127.0.0.1) or bind it to a private IP address that is not available on the Internet.

# network interfaces
net:
  port: 27017
  bindIp: 634.234.102.6

You should always watch your spaces! Always two by one, never tabs. After that, restart the MongoDB database.

systemctl restart mongod
systemctl restart mongodb
