# 1. INSTALL MongoDB PACKAGES OR BINARIES
# 2019-02-02: Sugarizer with Node.js 10.x requires MongoDB 2.6+ so
# https://andyfelong.com/2017/08/mongodb-3-0-14-for-raspbian-stretch/ is
# being used on Raspbian, all I found! (Raspbian's apt pkg is MongoDB 2.4.14)
#
# mongodb_stretch_3_0_14_core.zip (20M) & mongodb_stretch_3_0_14_tools.zip (15M)
# were backed up from andyfelong.com to http://download.iiab.io/packages/
#
# CLARIF: mongodb_stretch_3_0_14_core.zip IS IN FACT 3.0.14 (core) BUT...
# mongodb_stretch_3_0_14_tools.zip IS REALLY 3.0.15 (tools)

# 2022-06-07 #3236 MongoDB 5.0.9 "Illegal instruction" on RPi 4 also reveals:
# (1) dbPath fix in /etc/mongod.conf (~12 lines above) from /var/lib/mongodb
# to /library/dbdata/mongodb
# (2) mongod.lock is effectively NO LONGER A LOCK FILE -- but rather a PID
# file (it may be zero bytes, but never goes away) as confirmed with
# MongoDB 4.4.14 on RPi 4 and 5.0.9 Ubuntu 22.04 on x86_64. And now
# 'mongod --repair --dbpath /library/dbdata/mongodb/' IGNORES mongod.lock
# (3) mongodb.service should really use a more graceful way to shut down
# than 'killall mongod' (MongoDB 5+ shuts down w/ 15sec quiesce period).
# (4) MongoDB 6.0 is likely imminent but in the meantime a 2022-01-12 option
# (stanza below) is MongoDB 5.0.5 compiled for 64-bit RPi 4 and RPi 400:
# https://andyfelong.com/downloads/raspbian_mongodb_5.0.5.gz
