New Ubuntu install - initial setup prompting to configure opensearch?

brannen · May 16, 2024, 3:14pm

I just completed following the instructions to install Graylog 5.2 on a new Ubuntu server with Opensearch and Mongodb.

Upon connecting to the webpage, it opens “Graylog Initial Setup” and wants me to implement a “Data Node” - with an error, “No data nodes have been found.”

Graylog /var/log/graylog-server/server.log reports this error, repeating.

2024-05-16T14:01:01.117Z ERROR [VersionProbe] Unable to retrieve version from Elasticsearch node: unexpected end of stream on http://127.0.0.1:9200/… - \n not found: limit=0 content=….
2024-05-16T14:01:01.118Z INFO [VersionProbe] OpenSearch/Elasticsearch is not available. Retry #1

I’ve tried stopping and restarting services to no avail.

Hey @brannen

try commenting out the line

http_publish_uri = http://10.1.0.13:9000/

By chance did you leave OpenSearch Config file default?

network.host: 127.0.0.1

brannen · May 17, 2024, 2:56pm

Thanks @gsmith - I commented out the publish_uri like you said. I don’t know where the Opensearch Config file is, so I assume it’s default.

I restated the server with systemctl - still getting the same webpage, with these additional error messages.

There was an error fetching the data nodes: There was an error fetching a resource: undefined. Additional information: Not available

There was an error fetching the certificate authority: There was an error fetching a resource: undefined. Additional information: Not available

There was an error fetching the renewal policy: There was an error fetching a resource: undefined. Additional information: Not available

brannen · May 17, 2024, 2:59pm

Clicked on “resume startup”, which said it would cause the config to fail back to using Opensearch instance on localhost:9200.

Got error:

Could not resume startup

Resuming startup failed with error: FetchError: There was an error fetching a resource: undefined. Additional information: Not available

gsmith · May 17, 2024, 9:52pm

Hey @brannen

Where are you see this error at?

Addition steps.
Check the status of " OpenSearch, Graylog and MongoDb"
Check OpenSearch logs for any errors or warnings.

If possible can you show you OpenSearch Config file?

brannen · May 17, 2024, 10:23pm

I looked for the OpenSearch config file. I don’t know where it is.

brannen · May 17, 2024, 10:33pm

when I go to the http page.

brannen · May 17, 2024, 10:34pm

then click on “resume startup” and get message:

brannen · May 17, 2024, 10:34pm

then get a pop up in bottom right of browser.

gsmith · May 17, 2024, 10:53pm

Its the connection between Graylog and OpenSearch.

What does you OpenSearch configuration look like?

brannen · May 17, 2024, 11:10pm

Where can I find the opensearch configuration file?

gsmith · May 18, 2024, 12:07am

From this step here

brannen · May 19, 2024, 3:13pm

Here’s the uncommented config.

Hey @brannen

It tell your in the log file what happened. this section here

unknown setting [indicies.query.bool>

Try commenting out that line and restart your service , see if that works.

brannen · May 20, 2024, 11:20am

Holy Crap! I think it worked!

I’m at a “Welcome to Graylog” login screen! Thanks for your help!!! @gsmith

patrickmann · May 21, 2024, 5:52am

@brannen You had a typo there, that’s why it was unknown. It should be indices.query.bool.max_clause_count

brannen · May 21, 2024, 10:28am

Thanks @patrickmann . It’s up and working now.

gsmith · May 21, 2024, 11:35pm

Hey @brannen

That’s awesome
