Central documentation for the technical infrastructure of Librarybase

== 2025-10 Migration ==

* Goal: migrate Librarybase off of station1001 onto a VM on data1001
** New VM-based setup
** Need to clear station1001 to install Proxmox
* Export current environment
** Dump volumes
*** shared
*** mediawiki-mysql-data
*** query-service-data
*** elasticsearch-data
*** quickstatements-data
** For redundancy, create regular SQL and TTL dumps
** Commit Librarybase directory to private GitHub repository
* Set up librarybase-stage VM on data1001 and migrate exports to it
** Start with Debian 13 template
** Figure out how large storage volume needs to be
** RAM... start with 16 GB, go up from there
** CPU... start with 8 cores, go up from there
* Import Docker volumes
* Set up Librarybase directory and build images
* Modify domain name to stage.librarybase.org (and other subdomains)
* Verify new setup works
** Wiki loads
** Editing and saving pages
** Updating items, with changes reflected in SPARQL query service
** Uploading files, if I decide to enable that
** Indexing and searching
** QuickStatements
* Shut down librarybase-stage; clone and create librarybase-prod-1
* Configure static IP address on librarybase-prod-1
* Configure librarybase-prod-1 to use regular domain names
* Adjust orb-proxy configuration to point to Librarybase on new VM
* Launch services on librarybase-prod-1
* Adjust Librarybase DNS to point to data1001
* Once WRDB is migrated and WMF rsync is re-established on the new dumps server, shut down and cancel data1
* Future projects:
** Load balancing with librarybase-prod-2 (which will serve as the DB replica and secondary query service)
