How to run Elasticsearch 2.1.1 as root user in Linux machine

Question

I am trying to run Elasticsearch 2.1.1 in my Linux machine which I am the root user of it.

When I tried to execute the Elasticsearch.I am getting the following error

Answer 1

1. Open script file:

   vi bin/elasticsearch

2. Add property for allow root:

   ES_JAVA_OPTS="-Des.insecure.allow.root=true"

3. Save and close.
4. You can start by root now.

Good luck.

Answer 2

we need to create a new user in Linux server say user = es and grant sudo chown -R es elasticsearch-6.1.0/ then you can switch 'es' user account and run ./elasticsearch-6.1.0/bin/elasticsearch

Answer 3

There are two workarounds to resolve this issue :

Solution 1: download zip file n unzip then start by following command

bin/elasticsearch -Des.insecure.allow.root=true -d

Solution 2:

vi bin/elasticsearch

Add property to allow root to run two instance:

ES_JAVA_OPTS="-Des.insecure.allow.root=true"

Save and close. You can start by root now.

Answer 4

You can also create alias

alias elasticsearch='elasticsearch -Des.insecure.allow.root=true'

Add above line in bashrc file, After that elasticsearch command will work.

Answer 5

You should change the owner and group of the elasticsearch-X.X.X and run as that user. It works in elasticsearch-5.3.0

Answer 6

Based of the following code-snippet looks like you should be able to achieve this by enabling property es.insecure.allow.root

Example :

bin/elasticsearch -Des.insecure.allow.root=true
