[UPDATE: 26 August 2017 – The binaries referenced in this post only work with Raspbian Jessie! If you have upgraded to Raspbian Stretch on a R-Pi 3 or R-Pi 3B+, get the newer binaries]
The mongoDB documentation at mongodb.com states that 32-bit binaries are deprecated with release 3.2 and will be unavailable in future releases. The latest version with 32-bit support (i.e. R-Pi with Raspbian) is 3.0.14 as of March, 2017. I have compiled MongoDB 3.0.14 for Raspberry Pi 2 and 3. I needed a few tweaks to the build process I used to compile 3.0.9 and associated tools. Use the installation instruction in my previous blog post to install and run MongoDB 3.0.14 on R-Pi. The only change is to download newer files. I have compiled MongoDB and Tools with the SSL flag — so the SSL option is available.
