MongoDB 8.0.34-1

MongoDB is a document database: it keeps JSON-like documents in collections, with indexes, aggregations, transactions and full-text search. This app runs MongoDB 8.0 natively on the NAS (no Docker), with its shell mongosh and its database tools (mongodump, mongorestore, mongoexport, mongoimport, bsondump). The Compass Web app gives it a web interface.

• Built for the NAS's processors. MongoDB's own builds (5.0 and later) need AVX instructions, which the NAS's Intel Pentium / Celeron / Atom processors don't have: they'd stop at once with "Illegal instruction". This one is built from MongoDB's source for them (static/mongodb), the way MongoDB builds its releases but targeting x86-64-v2 (SSE4.2, no AVX), with its JavaScript engine's AVX2 code left out - as FreeBSD's, Gentoo's and others' builds for older processors do. Each build is checked on an emulated processor without AVX (storing and querying documents, JavaScript included). MongoDB doesn't support builds like this itself.
• It listens on port 27017 and always asks for a login. By default only programs on the NAS itself reach it (127.0.0.1); a switch on the page makes it reachable from the local network too. Its connections aren't encrypted (no TLS): keep it to your own network.
• Its administrator is admin (the root role: everything, on every database), with a password the app generates on its first start - shown on the management page, which can also change it (the Compass Web app follows). Connect with mongodb://admin:<password>@127.0.0.1:27017/?authSource=admin.
• Databases for your apps: the page makes a database with a login of its own (same name; read, write and indexes on that database only) and a generated password, shown once.
• Its memory: MongoDB's cache would otherwise take half the NAS's memory, less 1GB - the app gives it 512MB (256MB to 4GB on the page).
• The shell: /mnt/HD/HD_a2/Nas_Prog/mongodb/binaries/bin/mongosh over SSH (see the OpenSSH app). The app's own use of mongosh sends no usage data to MongoDB.
• Backups: every day at 03:15, every database with mongodump (while MongoDB runs), in one compressed archive, into Nas_Prog/_mongodb/backups (or a folder chosen on the page), keeping the newest 7. To restore one (over what's there):

``sh cd /mnt/HD/HD_a2/Nas_Prog/mongodb/binaries/bin ./mongorestore --host 127.0.0.1 --username admin --authenticationDatabase admin --gzip --drop \ --archive=/mnt/HD/HD_a2/Nas_Prog/_mongodb/backups/mongodb-<date>.archive.gz ``

(it asks for the administrator's password).

• It runs as its own user (mongodb, ID 67). Its data is kept in Nas_Prog/_mongodb, across reinstalls and removal: db/ and log/ are MongoDB's own; its configuration (conf/mongod.conf, written by the app at every start), password, settings and backups are root's.
• A new major version (9.0) is a separate step - MongoDB's data is upgraded one major version at a time. The app checks weekly for a new 8.0 release (a NAS alert).
• MongoDB's server is licensed under the SSPL (Server Side Public License); mongosh and the database tools under Apache-2.0 (their licences come with the package). OpenSSL 3.5 (for MongoDB's TLS support) is bundled. Intel models only.
