Can't install Logstash on Ubuntu

Elastic Stack Logstash
1

I've followed all the steps on the installation guide for Logstash but I keep getting this error:

Setting up nginx-core (1.10.0-0ubuntu0.16.04.4) ...
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

I've tried removing apache2 as I saw some posts mentioning that it helped, but it didn't work in my case. I've tried purging, completely removing and reinstalling but that doesn't work. I've also tried installing each nginx component seperately e.g core, full etc. but that doesn't work.

When I run: sudo yum install logstash

I get:

     You could try using --skip-broken to work around the problem
     You could try running: rpm -Va --nofiles --nodigest

When I run : sudo service logstash configtest
I get: logstash: unrecognized service

My system:

Distributor ID:	Ubuntu
Description:	Ubuntu 16.04.1 LTS
Release:	16.04
Codename:	xenial

Please help, thanks.

It looks like something else is wrong with your package system.
Also installing nginx is not part of our install process.

Yum on Ubuntu? Don't you mean apt?

Yes sorry, apt install. I get the same errors still.

I think you need to fix those nginx errors, that's ultimately causing the problem.

I imagine you are following an online tutorial something similar to DigitalOcean. You need to ensure you have installed the public key to pull from the Elasticsearch repository, update your apt package database, then, sudo apt-get install logstash.

Outside of that you will certainly need a web server such as apache or nginx for Kibana.

May the force be with you.

Kibana is a stand alone app though, why would they need a webserver as well?

@warkolm Correct, I retract my highlighted comment. It is all down to the context to which the elasticstack is being used.

Thanks.

Thanks for the support everyone, it's probably just my packet manager acting up. I've managed to get data into my Elasticsearch without Logstash so this problem has been resolved, sort of. Thanks.

the RPM packages are more stable in my opinion :slight_smile: install on centos :stuck_out_tongue:
