Utility to initialize or upgrade tinode DB

This utility initializes the tinode database (or upgrades an existing DB from an earlier version) and optionally loads it with data. To force database reset use command line option --reset=true.

Build the package:

  • RethinkDB go build -tags rethinkdb or go build -i -tags rethinkdb to automatically install missing dependencies.

  • MySQL go build -tags mysql or go build -i -tags mysql to automatically install missing dependencies.

  • MongoDB go build -tags mongodb or go build -i -tags mongodb to automatically install missing dependencies.

  • PostgreSQL go build -tags postgres or go build -i -tags postgres to automatically install missing dependencies.

Run

Run from the command line.

tinode-db [parameters]

Command line parameters:

  • --reset: delete the database then re-create it in a blank state; it has no effect if the database does not exist.
  • --upgrade: upgrade database from an earlier version retaining all the data; make sure to backup the DB before upgrading.
  • --no_init: check that database exists but don't create it if missing.
  • --data=FILENAME: fill tinode database with data from the provided file. See data.json.
  • --config=FILENAME: load configuration from FILENAME. Example config is included as tinode.conf.
  • --make_root=USER_ID: promote an existing user to root user, USER_ID of the form usrAbCDef123.
  • --add_root=USERNAME[:PASSWORD]: create a new user account and make it root; if password is missing, a strong password will be generated.

Configuration file options:

  • uid_key is a base64-encoded 16 byte XTEA encryption key to (weakly) encrypt object IDs so they don't appear sequential. You probably want to use your own key in production.
  • store_config.adapters.mysql and store_config.adapters.rethinkdb are database-specific sections:
  • database is the name of the database to generate.
  • addresses is RethinkDB/MongoDB's host and port number to connect to. An array of hosts can be provided as well ["host1", "host2"].
  • dsn is MySQL's Data Source Name.
  • replica_set is MongoDB's Replicaset name.

The uid_key is only used if the sample data is being loaded. It should match the key of a production server and should be kept private.

The default data.json file creates six users with user names alice, bob, carol, dave, frank, and tino (chat bot user). Passwords are the same as the user names with 123 appended, e.g. user alice gets password alice123; tino gets a randomly generated password. It also creates three group topics, and multiple peer to peer topics. Users are subscribed to topics and to each other. All topics are randomly filled with messages.
