Fehler beim Verbinden mit Redis auf localhost - Neu erstellt

Hello. Here are the error logs. I had to re-enable the email account, but even after doing so and tripple checking the app.yml settings, I’m still getting the following error.

Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED) subscribe failed, reconnecting in 1 second. Call stack ["/var/www/discourse/vendor/bundle/ruby/2.5.0/gems/redis-4.0.1/lib/redis/client.

Anyone have a thought on this one? I’m stuck.

Thanks!

It wouldn’t hurt to give us some more information here:

  • OS
  • install method

Hey Steven.

I was trying to update the version of Discourse through the web GUI, but was prompted to do it via the terminal due to the container being out of date.

OS - Ubuntu 16.04 on an EC2 instance.
Install Method - I used the ./launcher rebuild app

5

Any thoughts on this?

6

Is redis running in your container? It appears not.

7

Redis is up. I get a PONG back.

8

Is it running inside the container or on your host?

9

It’s running inside the container.

I just ran ./discourse-doctor and no errors were thrown. Test email came through successfully.

10

Can you paste the output from ps axf from inside the container?

There’s nothing I can see wrong. That looks like it should be working.

Is it still throwing the errors when you try and use it? Does ss -t show any redis connections?

Is there anything unusual done to the configuration?

13

I see a bunch of established connections to Redis (6379). The only thing I did was follow the directions from the web GUI telling me to upgrade the container in order to update the Discourse version.

Hallo zusammen. Hat jemand Fortschritte bei diesem Problem gemacht? Wenn ich meine Logs durchsehe, stelle ich fest, dass Discourse (speziell Unicorn, glaube ich) Schwierigkeiten hat, eine Verbindung zu Redis herzustellen. Wenn ich den Launcher verwende, um in die App zu wechseln (enter), antwortet redis-cli ping mit einem Pong… also bin ich mir nicht sicher, was los ist.

Weiß jemand, was ich tun kann?

Können Sie uns kurz etwas über Ihr Setup erzählen, falls es sich von dem des OPs unterscheidet? Jede Information hilft uns bei der Fehlerbehebung.
