Elasticsearch – Installation in this chapter, we will understand the installation procedure of Elasticsearch in detail. To install Elasticsearch on your local computer, you will have to follow the steps given below −

Step 1 − Check the version of java installed on your computer. It should be java 7 or higher. You can check by doing the following −

In Windows Operating System (OS) (using command prompt)−

> java -version

In UNIX OS (Using Terminal) −

$ echo $JAVA_HOME

Step 2 − Depending on your operating system, download Elasticsearch from www.elastic.co as mentioned below −

Step3 − Installation process for Elasticsearch is simple and is described below for different OS −

• Windows OS− Unzip the zip package and the Elasticsearch is installed.
• UNIX OS− Extract tar file in any location and the Elasticsearch is installed.

$wget
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch7.0.0-linux-x86_64.tar.gz

$tar -xzf elasticsearch-7.0.0-linux-x86_64.tar.gz

• Using APT utility for Linux OS− Download and install the Public Signing Key

$ wget -qo - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo
apt-key add -

Save the repository definition as shown below −

$ echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" |
sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list

Run update using the following command −

$ sudo apt-get update

Now you can install by using the following command −

$ sudo apt-get install elasticsearch

• Download and install the Debian package manually using the command given here −

$wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch7.0.0-amd64.deb
$sudo dpkg -i elasticsearch-7.0.0-amd64.deb0

• Using YUM utility for Debian Linux OS

$ rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

• ADD the following text in the file with .repo suffix in your “/etc/yum.repos.d/” directory. For example, elasticsearch.repo

elasticsearch-7.x]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

• You can now install Elasticsearch by using the following command

sudo yum install elasticsearch

Step 4 − Go to the Elasticsearch home directory and inside the bin folder. Run the elasticsearch.bat file in the case of Windows or you can do the same using command prompt and through the terminal in case of UNIX rum Elasticsearch file.

In Windows

> cd elasticsearch-2.1.0/bin
> elasticsearch

In Linux

$ cd elasticsearch-2.1.0/bin
$ ./elasticsearch

Note − In the case of windows, you might get an error stating JAVA_HOME is not set, please set it in environment variables to “C:\Program Files\Java\jre1.8.0_31” or the location where you installed java.

Step 5 − The default port for the Elasticsearch web interface is 9200 or you can change it by changing HTTP.port inside the elasticsearch.yml file present in the bin directory. You can check if the server is up and running by browsing http://localhost:9200. It will return a JSON object, which contains the information about the installed Elasticsearch in the following manner −

{
   "name" : "Brain-Child",
   "cluster_name" : "elasticsearch", "version" : {
      "number" : "2.1.0",
      "build_hash" : "72cd1f1a3eee09505e036106146dc1949dc5dc87",
      "build_timestamp" : "2015-11-18T22:40:03Z",
      "build_snapshot" : false,
      "lucene_version" : "5.3.1"
   },
   "tagline" : "You Know, for Search"
}
