How to access remotely to elasticsearch 5? - elasticsearch

Question

I want to access remotely to my elasticsearch version 5.
I tried to add this line in the elasticseach.yml file as I did with elassticsearch version 4 (which worked):
network.bind_host: 0.0.0.0
However, it doesn't work and elasticsearch displays an error and does not work.
[sagemcom#localhost bin]$ ./elasticsearch

Answer 1

If you look at the error error says
"ERROR: bootstrap checks failed
max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
"
Solve this issue as
Development Mode: If you are running elastic search in development mode we don't need to set the max_map_count. Just run as follows
docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:5.6.4
Production Mode: : I f you run in production you need to set the property as below.
Linux
The vm.max_map_count setting should be set permanently in /etc/sysctl.conf:
grep vm.max_map_count /etc/sysctl.conf
vm.max_map_count=262144
OR
sysctl -w vm.max_map_count=262144
Then Accessing it from remote is different case.
