I have installed elasticsearch on my server having this ip address W.X.Y.Z

I am able to run

./elasticsearch-6.3.2/bin/elasticsearch

The elasticsearch service is accessible on localhost (remote server) but I can't access it from my locale machine with the browser at this address http://W.X.Y.Z:9200/

Then I tried to change the elasticsearch-6.3.2/config/elasticsearch.yml file by adding the following lines (please see the attached screenshot)

network.host: 0.0.0.0

http.port: 9200

And at this time, I'm not able to run

./elasticsearch-6.3.2/bin/elasticsearch

I have updated /etc/security/limits.conf file by adding

elasticsearch  -  nofile  65536

elasticsearch  -  nproc  4096

enter image description here

this command ulimit -a still showing me this screen
enter image description here

And always, I'm not able to run ./elasticsearch command, I'm getting this result

Your problem is not related to network address, but to limits.

Have a look at what returns the linux shell command :

ulimit -a

Look at values max user processes and virtual memory, there are too low for running Elasticsearch. Temporary raise them with the ulimit command :

> ulimit -u 4096

> ulimit -v 262144

or permanently modify them like this :

sysctl -w vm.max_map_count=262144

(as explained here : https://www.elastic.co/guide/en/elasticsearch/reference/master/vm-max-map-count.html)

and edit /etc/security/limits.conf

elasticsearch  -  nofile  65536

elasticsearch  -  nproc  4096
