what is mongodb (written in C++, JavaScript, Python)
In 2013, 10gen changed its name to MongoDB Inc.[5]
On October 20, 2017, MongoDB became a publicly traded company, listed on NASDAQ as MDB with an IPO price of $24 per share.[6]
On November 8, 2018 with the stable release 4.0.4 the software’s license changed from AGPL 3.0 to SSPL v1.0. (wik)
Official MongoDB drivers use Apache License v2.0.
so a whole bunch and mix of licences making the whole thing a bit confusing.
how to install mongodb
if the user absolutely has to, for some reason not use mariadb (which is truly 100% Open Source GPL 2.0 licenced) then: As of today(Aug 29 2023) a binary for Debian 12 is not available yet. Although we can use Ubuntu’s repo to install MongoDB on Debian 12.

When running MongoDB in production on Linux, you should use Linux kernel version 2.6.36 or later, with either the XFS or EXT4 filesystem. If possible, use XFS as it generally performs better with MongoDB.
With the WiredTiger storage engine, use of XFS is strongly recommended to avoid performance issues that may occur when using EXT4 with WiredTiger. (src)
# mongo db # 1. create new dir mkdir /srv/mongodb # 2. stop mongodb systemctl stop mongod # 3. move the files mv -rv /var/lib/mongodb/* /srv/mongodb/ # 4. chown chown -R mongodb: /srv/mongodb # 5. restart systemctl start mongod
