Installing Tinode

Installing from Binaries

  1. Visit the Releases page, choose the latest or otherwise the most suitable release. From the list of binaries download the one for your database and platform. Once the binary is downloaded, unpack it to a directory of your choosing, cd to that directory.

  2. Make sure your database is running. Make sure it's configured to accept connections from localhost. In case of MySQL, Tinode will try to connect as root without the password. See notes below (Building from Source, section 4) on how to configure Tinode to use a different user or a password. MySQL 5.7 or above is required. MySQL 5.6 or below will not work.

  3. Run the database initializer init-db (or init-db.exe on Windows):

    ./init-db -data=data.json
    
  4. Run the tinode (or tinode.exe on Windows) server. It will work without any parameters.

    ./tinode
    
  5. Test your installation by pointing your browser to http://localhost:6060/

Docker

See instructions

Building from Source

  1. Install Go environment. Make sure Go version is at least 1.9. Building with Go 1.8 or below will fail!

  2. Make sure either RethinkDB or MySQL (or MariaDB or Percona) is installed and running. MySQL 5.7 or above is required. MySQL 5.6 or below will not work.

  3. Fetch, build Tinode server and tinode-db database initializer:

  • RethinkDb:

    go get -tags rethinkdb github.com/tinode/chat/server && go install -tags rethinkdb github.com/tinode/chat/server
    go get -tags rethinkdb github.com/tinode/chat/tinode-db && go install -tags rethinkdb github.com/tinode/chat/tinode-db
    
  • MySQL:

    go get -tags mysql github.com/tinode/chat/server && go install -tags mysql github.com/tinode/chat/server
    go get -tags mysql github.com/tinode/chat/tinode-db && go install -tags mysql github.com/tinode/chat/tinode-db
    

    Note the required -tags rethinkdb or -tags mysql build option.

    You may also optionally define main.buildstamp for the server by adding a build option, for instance, with a timestamp:

    -ldflags "-X main.buildstamp=`date -u '+%Y%m%dT%H:%M:%SZ'`"
    

    The value of buildstamp will be sent by the server to the clients.

  1. Open tinode.conf. Check that the database connection parameters are correct for your database. If you are using MySQL make sure DSN in "mysql" section is appropriate for your MySQL installation. Option parseTime=true is required.
	"mysql": {
		"dsn": "root@tcp(localhost)/tinode?parseTime=true",
		"database": "tinode"
	},
  1. Download javascript client for testing:
  1. Now that you have built the binaries, follow instructions in the Installing from Binaries section for running the binaries except in step 3 the initializer is called tinode-db (tinode-db.exe on Windows), not init-db.

Running a Standalone Server

  1. Make sure your database is running:
  1. Run DB initializer

    $GOPATH/bin/tinode-db -config=$GOPATH/src/github.com/tinode/chat/tinode-db/tinode.conf
    

    add -data=$GOPATH/src/github.com/tinode/chat/tinode-db/data.json flag if you want sample data to be loaded:

    $GOPATH/bin/tinode-db -config=$GOPATH/src/github.com/tinode/chat/tinode-db/tinode.conf -data=$GOPATH/src/github.com/tinode/chat/tinode-db/data.json
    

    DB intializer needs to be run only once per installation. See instructions for more options.

  2. Unpack JS client to a directory, for instance $HOME/tinode/webapp/ by first unzipping https://github.com/tinode/webapp/archive/master.zip then extract tinode.js from https://github.com/tinode/tinode-js/archive/master.zip to the same directory.

  3. Run server

    $GOPATH/bin/server -config=$GOPATH/src/github.com/tinode/chat/server/tinode.conf -static_data=$HOME/tinode/webapp/
    
  4. Test your installation by pointing your browser to http://localhost:6060/. The static files from the -static_data path are served at web root /. You can change this by editing the line static_mount in the config file.

Running a Cluster

  • Install and run the database, run DB initializer, unpack JS files as described in the previous section. Both MySQL and RethinkDB supports cluster mode. You may consider it for added resiliency.

  • Cluster expects at least two nodes. A minimum of three nodes is recommended.

  • The following section configures the cluster.

	"cluster_config": {
		// Name of the current node.
		"self": "",
		// List of all cluster nodes, including the current one.
		"nodes": [
			{"name": "one", "addr":"localhost:12001"},
			{"name": "two", "addr":"localhost:12002"},
			{"name": "three", "addr":"localhost:12003"}
		],
		// Configuration of failover feature. Don't change.
		"failover": {
			"enabled": true,
			"heartbeat": 100,
			"vote_after": 8,
			"node_fail_after": 16
		}
	}
  • self is the name of the current node. Generally it's more convenient to specify the name of the current node at the command line using cluster_self option. Command line value overrides the config file value. If the value is not provided either in the config file or through the command line, the clustering is disabled.
  • nodes defines individual cluster nodes. The sample defines three nodes named one, two, and tree running at the localhost at the specified cluster communication ports. Cluster addresses don't need to be exposed to the outside world.
  • failover is an experimental feature which migrates topics from failed cluster nodes keeping them accessible:
    • enabled turns on failover mode; failover mode requires at least three nodes in the cluster.
    • heartbeat interval in milliseconds between heartbeats sent by the leader node to follower nodes to ensure they are accessible.
    • vote_after number of failed heartbeats before a new leader node is elected.
    • node_fail_after number of heartbeats that a follower node misses before it's considered to be down.

If you are testing the cluster with all nodes running on the same host, you also must override the listen and grpc_listen ports. Here is an example for launching two cluster nodes from the same host using the same config file:

./server -config=./tinode.conf -static_data=./webapp/ -listen=:6060 -grpc_listen=:6080 -cluster_self=one &
./server -config=./tinode.conf -static_data=./webapp/ -listen=:6061 -grpc_listen=:6081 -cluster_self=two &

A bash script run-cluster.sh may be found useful.

Enabling Push Notifications

Follow instructions.

Note on Running the Server in Background

There is no clean way to daemonize a Go process internally. One must use external tools such as shell & operator, systemd, launchd, SMF, daemon tools, runit, etc. to run the process in the background.

Specific note for nohup users: an exit must be issued immediately after nohup call to close the foreground session cleanly:

nohup $GOPATH/bin/server -config=$GOPATH/src/github.com/tinode/chat/server/tinode.conf -static_data=$HOME/tinode/webapp/ &
exit

Otherwise SIGHUP may be received by the server if the shell connection is broken before the ssh session has terminated (indicated by Connection to XXX.XXX.XXX.XXX port 22: Broken pipe). In such a case the server will shutdown because SIGHUP is intercepted by the server and interpreted as a shutdown request.

For more details see https://github.com/tinode/chat/issues/25.

You can’t perform that action at this time.
