# 1.2 Set up Elasticsearch
This enhancement is only available in KiyoCRM from version 7.11 onwards.
KiyoCRM 7.11 requires Elasticsearch 5.6. KiyoCRM 7.12 requires Elasticsearch 7.
Elasticsearch requires Java 8 to run, supporting only `Oracle Java` and `OpenJDK`.
The quickest ways of having an Elasticsearch server up and running is by either using the official Docker image, or the .deb package for Debian-based systems (like Ubuntu).
In this guide we will assume that you are attempting to install Elasticsearch on an Ubuntu machine. Refer to the [official documentation](https://www.elastic.co/guide/en/elasticsearch/reference/5.6/install-elasticsearch.html) to know how to install Elasticsearch in different ways.
This guide will teach you how to have a development server up and running with very little configuration, either by installing via Docker or .deb package. Please keep in mind this guide is not suitable for setting up a production Elasticsearch server.
## Install via Docker (recommended)
Be sure that the current user belongs to the `docker` group or you’ll receive permission issues.
Download image:
```bash
docker pull docker.elastic.co/elasticsearch/elasticsearch:5.6.10
```
### Start with `docker run`
Start Elasticsearch. This is ideal for a test/development server.
```bash
docker run -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" -e "xpack.security.enabled=false" \
docker.elastic.co/elasticsearch/elasticsearch:5.6.10
```
### Start with `docker-compose`
Create a new `docker-compose.yml` file or add the elasticsearch configuration your pre-existing docker-compose.
```yaml
version: '3'
services:
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:5.6.10
container_name: elasticsearch
restart: unless-stopped
ports:
- 9200:9200
- 9300:9300
environment:
- discovery.type=single-node
- xpack.security.enabled=false
- "ES_JAVA_OPTS=-Xms512m -Xmx512m"
```
And start with:
```bash
docker-compose up
```
## Install via .deb (not recommended)
Download and install the public signing key:
```bash
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
```
You may need to install the `apt-transport-https` package on Debian before proceeding:
```bash
sudo apt-get install apt-transport-https
```
Save the repository definition to `/etc/apt/sources.list.d/elastic-5.x.list`:
```bash
echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-5.x.list
```
Update the repository and install OpenJDK 11 and Elasticsearch:
```bash
sudo apt-get update && sudo apt-get install openjdk-11-jre elasticsearch
```
You might need to tweak the OpenJDK version to match the one available for your distribution.
Start Elasticsearch with:
```bash
sudo systemctl start elasticsearch.service
```
or on older Ubuntus:
```bash
/etc/init.d/elasticsearch start
```
## Test Installation
Check if the server is running with:
```bash
curl -X GET "localhost:9200/"
```
And you should receive something like this:
```json
{
"name" : "B5VzMdk",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "KGoWI84GQ8SZipmDaeA7pA",
"version" : {
"number" : "5.6.10",
"build_hash" : "b727a60",
"build_date" : "2018-06-06T15:48:34.860Z",
"build_snapshot" : false,
"lucene_version" : "6.6.1"
},
"tagline" : "You Know, for Search"
}
```
Note that the current setup does not provide authentication. Remember to secure your Elasticsearch server before going to production, or your data will be vulnerable!
