the configuration of elasticsearch

cluster.name: cluster-1
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
node.master: true
node.data: false
index.number_of_shards: 1
index.number_of_replicas: 0
network.host: "192.168.2.44"
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
#
# Set a custom port for HTTP:
#
http.port: 9200

and logstash pipeline configuration

# OUTPUT HERE
output {
stdout { }
elasticsearch{
    type => "log"
    embedded => false
    host => "192.168.2.183"
    port => "9200"
    cluster => "cluster-1"
    node_name => "node-1"
    }
}

Also you have the IP 192.168.2.44 configured as network.host and Logstash tries to connect to 192.168.2.183

Changed to

network.host: "0.0.0.0"
#
# Set a custom port for HTTP:
#
http.port: 9200

ok, can give me some explanation for this, and how to do it

6

So if you don't run ES as root, does it work now?

7

am just changing the ownership of the home folder of elasticsearch

8

Just log out of root and try to start again.

9

now it seems to like this

ubuntu@ip-192-168-2-183:/usr/share/elasticsearch$ bin/elasticsearch
bin/elasticsearch-env: line 70: /etc/default/elasticsearch: Permission denied
