I installed elasticsearch.90.7 with a deb file in ubuntu. I tried to uninstall elasticsearch.90.7 with this command:

sudo apt-get --purge autoremove elasticsearch

And then I downloaded elasticsearch-1.6.0.deb to install elasticsearch 1.6.

When I run this command to install elasticsearch 1.6 by deb file:

dpkg -i elasticsearch-1.6.0.deb

It shows me this:

Selecting previously unselected package elasticsearch.
(Reading database ... 89826 files and directories currently installed.)
Preparing to unpack elasticsearch-1.6.0.deb ...
Creating elasticsearch group... OK
Creating elasticsearch user... OK
Unpacking elasticsearch (1.6.0) ...
Setting up elasticsearch (1.6.0) ...
Processing triggers for ureadahead (0.100.0-16) ...

When I start elasticsearch with service elasticsearch start it's starting, but when i run this command: curl http://localhost:9200

It shows this error:

curl: (7) Failed to connect to localhost port 9200: Connection refused

I think elasticsearch is not installed properly. I want know what I should do to install elasticsearch properly.

  • Please post the output of "lsof -Pni | grep 9200" (or netstat equivalent).

  • Have you checked the process tree to see if it's actually running, or the ES to figure out what's going on?

(1) Remove previous versions of ElasticSearch:

sudo apt-get --purge autoremove elasticsearch

(2) Remove the ElasticSearch directories:

sudo rm -rf /var/lib/elasticsearch/
sudo rm -rf /etc/elasticsearch

(3) Install ElasticSearch 1.6:

sudo dpkg -i elasticsearch-1.6.0.deb

(4) Start the service:

sudo service elasticsearch start

(5) Test if it works:

sudo service elasticsearch status
curl -XGET "http://localhost:9200/_cluster/health?pretty=true"
curl "localhost:9200/_nodes/settings?pretty=true"
  • I get elasticsearch: unrecognized service after installing the .deb file and trying to run sudo service elasticsearch start. Mar 5, 2016 at 14:49
  • Try ``` sudo /etc/init.d/elasticsearch start ``` Aug 18, 2016 at 22:00
  • I am using elasticsearch version 5.2.0. And I follow your steps and now when I check log I am getting the error.

It appears you have installed/updated ElasticSearch correctly and it appears to be running. You needn't re-install it.

It may be your CURL command is incomplete. Try this instead:

curl -XGET 'http://localhost:9200/_cluster/health?pretty=true'

You should receive a json response which reads like this:

  "cluster_name" : "your_clusters_name",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0

    I don't see your explanation of why he gets a Connection refused on port 9200. This answer is irrelevant without it. Jul 22, 2015 at 21:47

Instead of starting elasticsearch with service elasticsearch start, try to start it with the following command:

sudo /usr/share/elasticsearch/bin/elasticsearch --default.config=/etc/elasticsearch/elasticsearch.yml --default.path.home=/usr/share/elasticsearch --default.path.logs=/var/log/elasticsearch --default.path.data=/var/lib/elasticsearch --default.path.work=/tmp/elasticsearch --default.path.conf=/etc/elasticsearch

And see if the output of the application is giving you any advice on what's going wrong ...

Posting the output here may help us to find the origin of the problem.


"sudo service elastic search start

elasticsearch: unrecognised service"

I had a corrupt ElasticSearch installation.

I deleted and re-installed ElasticSearch as mentioned in (Remove previous versions of ElasticSearch:)

Problem solved, good luck
