Initial install question

Elastic Stack Elasticsearch
1

Hi,

I have been through many documents on how to get elastic search up and running. I cannot get it to connect when I use the ./elasticsearch command. I am using Ubuntu server 16.04 and the latest version of elastic search from the repository.

These are the only settings in my configuration file. I also set the elasticsearch in the service limits.
cluster.name: CORES
node.name: ${HOSTNAME}
path.conf: /etc/elasticsearch/
path.data: /var/lib/elasticsearch
bootstrap.mlockall: true
network.bind_host: 127.0.0.1
network.publish_host: 10.160.21.65
network.host: 127.0.0.1
transport.tcp.port: 9300
transport.tcp.compress: true
http.port: 9200

This is the error I receive

This error is the only thing in my CORES.log file. The CORES_index_search_showlog.log is empty as well as CORES_index_indexing_slowlog.log

Something to add in. When I run sudo service elasticsearch status I get:
● elasticsearch.service - LSB: Starts elasticsearch

Mar 02 15:39:15 ELSNETAPPLP1 systemd[1]: Started LSB: Starts elasticsearch.

However, when I run a ps -A it is not in the list. A netstat -plnt does not show port 9200 or 9300 open and listening.

I don't think you can bind to localhost but publish as non-loopback?

Mark,

I had it set to publish the actual IP because I was under the impression that was the IP that was being sent out to other clients to connect to. I may be wrong though.

Something interesting I have found. With the information put in, I have it listening and responding on IPV6 but not IPV4.

Any thoughts on how to get it to IPV4??
