How to get InfluxDB version via shell

Question

The influx shell has a -version flag, but not influx server:

/path/to/bin/influx -version InfluxDB shell version: 1.1.1  /path/to/bin/influxd -version flag provided but not defined: -version  /path/to/bin/influxd -v flag provided but not defined: -v 

Should I assume that influx shell and influx server will always have the same version ?

Answer 1

curl -sL -I localhost:8086/ping

You should get something like:

HTTP/1.1 204 No Content Content-Type: application/json Request-Id: c7c8f7d7-b7ef-11e7-8002-000000000000 X-Influxdb-Version: 1.3.6 Date: Mon, 23 Oct 2017 12:43:33 GMT 

If you are using HTTPS:

curl -skL -I 'https://myhost:8086/ping' 

Answer 2

It's most likely that the InfluxDB client and InfluxDB server on the same server are the same versions. If you want to specifically check the server version, you can do so.

In versions 0.11 (at least) and above, the influxdb executable accepts a version argument:

% /usr/bin/influxd version InfluxDB v1.2.1 (git: master 3ec60fe2649b51a85cd1db6c8937320a80a64c35)
