There is no official support from MongoDB for Debian ARM 64 or Raspbian64 Linux OS.  You can, however, compile the MongoDB Community Edition from source.  I did just that 🙂  It did, however, take three days and a burnt Raspberry Pi 4 to accomplish 🙁  I’ll provide a link to instructions to create the executables for mongod, mongos and mongo — as well as provide a few tips to successfully compile.  Better and easier than that, I provide links to already compiled versions with instructions on how to install and use.

I recently decided to “check-in” on the status of Raspbian64, the 64 bit version of Raspberry Pi OS which is not yet released. I had been using Ubuntu Server 20.04 ARM 64-bit on a couple of Raspberry Pi 4s for various projects. One benefit of Ubuntu was official support for MongoDB. I was looking for a complete optimized Raspbian OS with GUI AND MongoDB. Searching around, I did not find what I wanted. I decided to try and create it.

You’ll need to find and install the latest Raspbian64 image. Use the “full” version as opposed to “lite” as you need all the tools, such as dev libraries, g++-8 and git that come with the full version. Not that you could not use “lite” and install everything needed 😉 This is the version I use with its GUI as it has great internet and development tools. I can also use via VNC in headless mode.

If you really want to compile MongoDB Community Edition 4.4.8 from source, you can find instructions in this thread in the MongoDB Community Forums. NOTE that you will need to add at least a 2GB swap file on your 4GB RAM R-Pi 4. You should change the git command that grabs version 4.2.8 so that you get the latest 4.4.8.

git clone -b r4.4.8 https://github.com/mongodb/mongo.git

Compiling is straightforward but I had a few issues along the way. I used a Raspberry Pi 4 in a Flirc case with a USB 3 attached SSD. I have had my Pi 4 overclocked to 2GHz with no issues or overheating for quite some time. I love the Flirc case as it looks good and the whole aluminum case is a big heatsink. The first couple of times I tried to compile MongoDB from source, the build would just die after an hour or so. By monitoring the Pi with another ssh login, it looked like it was running out of real and swap memory. I could also see the 4 cores were running at over 90% usage. I upped the swap file to 2GB and tried again. This time, the build lasted over 4 hours before hanging (died silently). I picked up the Pi 4 case and almost burned my hand (ouch!). Being foolish, I tried again — with, of course the same result — a hung Pi that now had the electronic overheat smell 🙁 I moved the SSD to my *stock* Raspberry Pi 400 and tried again. Fortunately, the compile (more-or-less) picked up where it died. After about 5 hours, the compile completed without errors. I now had executable binaries for mongod, mongos and mongo (the “old” Javascript shell).

I am providing the three binaries here in a tar gz file to save folks time and effort.

Install and use

Ensure you are running the latest version of Raspbian64 OS with all updates. Download and unzip the raspbian_mongodb_4.4.8.gz file.  You’ll have 3 files, mongod, mongos and mongo. Move the executables to /usr/bin and change owner and group to root.  Ensure permissions are set to executable.

tar zxvf raspbian_mongodb_4.4.8.gz
sudo mv mongo* /usr/bin
sudo chown root:root /usr/bin/mongo*
sudo chmod 755 /usr/bin/mongo*

Create the mongodb user.

sudo adduser --no-create-home --disabled-login mongodb

Create the configuration file:  /etc/mongodb.conf and add the following lines:

sudo vi /etc/mongodb.conf
# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# where to write logging data.
systemLog:

  logAppend: true
  path: /var/log/mongodb/mongod.log

# Where and how to store data.

Create the log file and data directory. Change owner and group.

sudo mkdir -p /var/log/mongodb/
sudo chown -R mongodb:mongodb /var/log/mongodb/
sudo mkdir /data
sudo chmod 777 /data
sudo mkdir -p /data/db
sudo chown -R mongodb:mongodb /data/db

Create the systemctl service file to stop/start mongod process and add the following lines:

sudo vi /lib/systemd/system/mongodb.service
[Unit]
Description=An object/document-oriented database
Documentation=man:mongod(1)
After=network.target

[Service]
User=mongodb

# (processes/threads)
LimitNPROC=64000
ExecStart=/usr/bin/mongod --quiet --config /etc/mongodb.conf

[Install]
WantedBy=multi-user.target

You can now start/stop the mongodb service (mongod). Remember to stop gracefully before rebooting your system!

$ sudo service mongodb start

$ sudo service mongodb status

You can also now run mongo, an interactive JavaScript shell interface to MongoDB

$ mongo
