How To Install Elasticsearch 1.7 on ubuntu

Install Java 8

sudo add-apt-repository -y ppa:webupd8team/java
sudo apt-get update
sudo apt-get -y install oracle-java8-installer

Now that Java 8 is installed, let’s install ElasticSearch.

Run the following command to import the Elasticsearch public GPG key into apt:

wget -qO - | sudo apt-key add -

Create the Elasticsearch source list:

echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/elasticsearch-1.7.list

Update your apt package database:

sudo apt-get update

Install Elasticsearch with this command:

sudo apt-get -y install elasticsearch

Elasticsearch is now installed. Let’s edit the configuration:

sudo vim /etc/elasticsearch/elasticsearch.yml


to localhost

Now start Elasticsearch:

sudo service elasticsearch restart

Test it

curl -X GET 'http://localhost:9200'
