"influx" connects to the wrong port

Welcome & Getting Started
1

Hello, all!

I am new to Ubuntu and InfluxDB, and I am having trouble with reaching influxDB.
Starting the DB with influxd / service influxdb start works fine, and if I check the status, it is running.
The status message also shows the config file the process is using, which seems to be the correct one.

However, if I attempt to start the CLI with “influx”, I get the following error message:

Note: Get http: // localhost : 9999/api/v2/setup: dial tcp [::1]:9999: connect: connection refused.
(Note that it is not complaining that the service isn’t running, which results in a pretty similar error message. I broke up the link to allow posting.)

I’ve been told by support that:

  1. I’m not supposed to use their email and

By default, InfluxDB uses TCP port 9999 for client-server communication over the InfluxDB HTTP API. So you need to ensure that the port is not set to 9999 using 1.7 as this will not work. I have posted some additional documentation around this below.

https:// Get started with InfluxDB | InfluxDB OSS v2 Documentation

https:// https://docs.influxdata.com/influxdb/v1/introduction/install/

Which doesn’t really help me, as I’ve already set the binding port to :8086 in the influxdb.conf file (and adjusted the environment variable, too).

Unfortunately, influx still insists on trying to use 9999. I tried googling and looking for similar problems, but I’m at the end of my wits. Can anyone help me out?

Thank you so much in advance,
wade

Have a look at the influx cli docs here
When you run the influxcli you can pass parameters like:

  • -host
  • -port
    and others.

I don’t know why by default it points you to port 9999, can you post an extract of the influxdb instance configuration?

3

Just to clarify: is the InfluxDB service running successfully on :8086? If you’re using 2.0 (and it seems like you are if it’s defaulting to :9999), you can use the --host flag to pass in the url.

4

Thank you for pointing that out. I will try to run it with the optional parameters when I’m at work tomorrow and then report back with the results!

Sorry, I’m not sure what you mean with the “influxdb instance configuration”? The config file?

5

Hello!
Yes, when I start the influxdb service and then check its status it says that it is running on :8086, I believe.

That is a really good guess, but I’m not running 2.0 anymore.
I had it installed and used it before but uninstalled and removed it because I need 1.7. (The one that is running is also 1.7, I’m pretty sure.)

My worry is that some 2.0 files were left over somewhere and are now messing with me.
I will try it with the flags tomorrow and report back. I’ll also send the status logs of the running service.

Thank you for your help!

@katy, @Giovanni_Luisotto

Here is the output I receive when I start the database with “influxd”.
Sorry for the enormous code block. I don’t know which bits might be useful, so I don’t want to leave anything out.

As you can see in the first line, it is indeed v1.7.9.

If I then try to access the database, I get this message:

[links broken up to allow posting]

root@mqttServer:~# influx --host “http: // localhost:8086”
Note: 404 page not found.

However, a coworker told me to start the db with “service influxdb start”, which I try to do instead.

If I then try to pass the --host parameter to “influx”, it does try to connect to :8086, but the connection is still refused.

[links broken up to allow posting]

root@mqttServer:~# influx --host “http : //localhost:8086”
Note: Get http : // localhost : 8086/api/v2/setup: dial tcp [::1]:8086: connect: connection refused.

Why is it trying to access the api/v2/setup? What am I doing wrong?

7

Can you share the output of influx --version please?

8

It looks like you have influxd 1.7.9 but influx 2.0.0

9

Sadly I have no idea about what’s wrong with it.
Is a fresh install a viable option for you?
If yes, you just need to delete all the influxdb files related to this instance, to see where they are stored have a look at the .conf file, you should have a bunch of parameters named “dir”, that are used to define the paths to the instance files.

Hello! Thank you for your reply!

Here’s the … output:

root@mqttServer:~# influx --version

Use “influx [command] --help” for more information about a command.

edited to include full output.

How does that 1.7 / 2.0 mashup happen? I would believe in a heartbeat that I didn’t do a clean uninstall of 2.0, but I had someone else, who knows what they’re doing, uninstall it for me because it didn’t work properly :^( I truly am lost

@Giovanni_Luisotto
If all else fails I think that’s my only option!
Thank you so much for your help! I really appreaciate it :^)

11

Can you show all the output please? Don’t hide the available commands.

You can also try influx version too. Please provide both. I thought --version worked, but I’m wrong :+1:

12

Yes, sorry! I edited my previous reply to show the available commands.

Here you, unfortunately, go:

root@mqttServer:~# influx version
Error: unknown command “version” for “influx”
Run ‘influx --help’ for usage.

And then, of course, the same sad tale:

root@mqttServer:~# influx --help

influx [flags]
influx [command]

-t, --token string API token to be used throughout client calls

Use “influx [command] --help” for more information about a command.

13

Yes, this is the 2.0 CLI.

Can you show me which influx and which influxd please?

Thanks for your patience, we’re almost there!

14

Please, thank YOU for your patience! :^) I really appreaciate it.

Here you go:

root@mqttServer:~# which influx
/usr/local/bin/influx

root@mqttServer:~# which influxd
/usr/bin/influxd

Those should probably be in the same directory, huh?

15

So I’m going to assume you’ve installed InfluxDB 1 through the system packages and manually installed InfluxDB 2.

I’d recommend you either rename or delete InfluxDB 2 (Assuming you want InfluxDB 1)

To do that, do:

# to rename
sudo mv /usr/local/bin/influx /usr/local/bin/influx2

# to delete
sudo rm -f /usr/local/bin/influx
16

Just to clarify, once you do one of those commands; you should have access, through influx, to the InfluxDB 1 CLI to continue as normal.

17

Thank you!
I renamed it, and now it is trying to connect to 8086 :^)
Although unsuccessfully…

root@mqttServer:~# service influxdb start
root@mqttServer:~# influx
Failed to connect to http://localhost:8086: Get http://localhost:8086/ping: dial tcp [::1]:8086: connect: connection refused
Please check your connection settings and ensure 'influxd' is running.
18

Can you show us the output of journalctl -u influxdb, please?

19

Of course. Here it is:

journalctl -u influxdb --no-pager
