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)
