Manage ElasticSearch

You can ask us to install ElasticSearch on your hosting account. Make sure you mention which exact version you would like.

ElasticSearch IP and Port

We will run the ElasticSearch daemon on the IP address of your hosting account.

We will use the default port for ElasticSearch, which is 9200

The communication with ElasticSearch works via the REST / HTTP protocol.

For security reasons port 9200 is not directly accessible from outside the hosting server.
The easiest way is to access ElasticSearch using curl commands via SSH, examples below.

Manage ElasticSearch using Curl

These commands can be executed when you are connected via SSH to the hosting account where the ElasticSearch is used.

This command will show the version of ElasticSearch and the tagline "You Know, for Search".

Fix ElasticSearch status Yellow

There is probably only one ElasticSearch node running for your shop, unless your shop is on a cluster of servers. The ElasticSearch status can become "Yellow" because ElasticSearch likes to spread replica's of data among multiple nodes. To make ElasticSearch "Green" again, execute the following commands:

curl -H "Content-Type: application/json" -XPUT "http://$VHOSTIP:9200/_settings" -d '{"index":{"number_of_replicas":0}}'
curl -H 'Content-Type: application/json' -XPUT "http://$VHOSTIP:9200/_cluster/settings" -d '{"transient":{"cluster.routing.allocation.enable":"all"}}'

Access ElasticSearch from your Browser or Desktop Application

If you would like to access ElasticSearch from your desktop or browser, you need create a TCP Tunnel over SSH. Replace the __USER__@__DOMAIN__  by the values you normally use to connect to SSH. You can find the value __VHOSTIP__ as described in the first paragraph of this article.

ssh  __USER__@__DOMAIN__  -p 2222  -L 9200:__VHOSTIP__:9200

As long as this connection is open, you can access ElasticSearch in your browser or desktop application on http://localhost:9200
