Connection refused on port 9200

Elastic Stack Elasticsearch
1

Hi,

I'm following the guide over at digitalocean getting the ELK stack up on Ubuntu server 16. I've installed elasticsearch 2.4.1 and I just can't seem to get any sort of response out of it, never mind setting up Nginx and Kibana etc,

curl: (7)Failed to connect to localhost port 9200: Connection refused

Here is the output of the system status:

nadmin@anon:~$ sudo systemctl status elasticsearch
â elasticsearch.service - Elasticsearch
Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: enabled)

Nov 08 14:45:40 anon systemd[1]: elasticsearch.service: Failed with result 'exit-code'.

And the Network section of my yml file:

---------------------------------- Network -----------------------------------

Set the bind address to a specific IP (IPv4 or IPv6):

network.host: localhost
network.bind_host: localhost
network.publish_host: localhost

Set a custom port for HTTP:

http.port: 9200

For more information, see the documentation at:

http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html

Obviously these are 'current' state. I've googled round and tried various things for troubleshooting. Disabled the firewall, commented out ipv6 in /etc/hosts - what can I check next?

Check Elasticsearch's log file (/var/log/elasticsearch) for clues.

Hi,
I have followed many of the tutorials over at DO as well as the ELK posts. Please be wary of the system requirements, exact E,L,K and NGINX versions at use in-line with UB16.04

Have you followed it line for line, amending anything that is of a red font color.

Just for info, completely rebuilt the VM again and installed each item step by step testing as I went. Now working. I think the problem was around the ssl htpasswd user for future reference.

Thanks anyway.
