Installation

Install Mongodb on Raspberry PI4.

SHH

Access Raspberry PI using SSH Client.

ssh ubuntu@<raspberry-pi-ip-address>.

Default Passwordはubuntuです。

Step 1: Update Raspberry Pi Packages

To begin installing MongoDB on your Raspberry Pi device, make sure the packages on your system are up-to-date and update the packages using the following command

sudo apt update
sudo apt upgrade

Step 2: Install MongoDB

Step2.1

Install MongoDB 4.4 GPG key.

wget -qO – https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add –

Step2.2

Add the source location of the MongoDB package.

echo “deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

Step2.3

Download the MongoDB package details.

sudo apt-get update

Step2.4

Install MongoDB.

sudo apt-get install -y mongodb-org

Run MongoDB

Ubuntu 20.04 uses Systemd to run background services, so set mongod to run in the background.

# Ensure mongod config is picked up:
sudo systemctl daemon-reload

# Tell systemd to run mongod on reboot:
sudo systemctl enable mongod

# Start up mongod!
sudo systemctl start mongod

Check Result

You can verify that the service is running correctly by executing the following command.

$ sudo systemctl status mongod

Activeはfailedです。なにか間違ってるのでもう一度インストールしていきましょう。

Install Again

This error indicates that the CPU is incompatible with mongodb.

Step1

Execute the following command to stop the mongod process

sudo service mongod stop

Step2

Remove all previously installed MongoDB packages.

sudo apt-get purge mongodb-org*

Step3

Delete the MongoDB database and log files.

sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb

Step4

Import the public key used by the package management system.

wget -qO – https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add –

echo “deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

Step5

Update Apt.

sudo apt-get update

Step6

Install mongodb.

sudo apt-get install mongodb-org=4.4.8 mongodb-org-server=4.4.8 mongodb-org-shell=4.4.8 mongodb-org-mongos=4.4.8 mongodb-org-tools=4.4.8

Step7

Check the Installation with the mongod command.
