Install Elasticsearch with .zip on Windows

Download the .zip archive for Elasticsearch 9.0.0-beta1 from: https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-9.0.0-beta1-windows-x86_64.zip

Unzip it with your favorite unzip tool. This will create a folder called elasticsearch-9.0.0-beta1, which we will refer to as %ES_HOME%. In a terminal window, cd to the %ES_HOME% directory, for instance:

cd C:\Program Files\elasticsearch-9.0.0-beta1

Run the following command to start Elasticsearch from the command line:

.\bin\elasticsearch.bat

When starting Elasticsearch for the first time, security features are enabled and configured by default. The following security configuration occurs automatically:

The password for the elastic user and the enrollment token for Kibana are output to your terminal.

We recommend storing the elastic password as an environment variable in your shell. Example:

$ELASTIC_PASSWORD = "your_password"

If you have password-protected the Elasticsearch keystore, you will be prompted to enter the keystore’s password. See Secure settings for more details.

By default Elasticsearch prints its logs to the console (STDOUT) and to the <cluster name>.log file within the logs directory. Elasticsearch logs some information while it is starting, but after it has finished initializing it will continue to run in the foreground and won’t log anything further until something happens that is worth recording. While Elasticsearch is running you can interact with it through its HTTP interface which is on port 9200 by default.

To stop Elasticsearch, press Ctrl-C.

When Elasticsearch starts for the first time, the security auto-configuration process binds the HTTP layer to 0.0.0.0, but only binds the transport layer to localhost. This intended behavior ensures that you can start a single-node cluster with security enabled by default without any additional configuration.

Before enrolling a new node, additional actions such as binding to an address other than localhost or satisfying bootstrap checks are typically necessary in production clusters. During that time, an auto-generated enrollment token could expire, which is why enrollment tokens aren’t generated automatically.

Additionally, only nodes on the same host can join the cluster without additional configuration. If you want nodes from another host to join your cluster, you need to set transport.host to a supported value (such as uncommenting the suggested value of 0.0.0.0), or an IP address that’s bound to an interface where other hosts can reach it. Refer to transport settings for more information.

To enroll new nodes in your cluster, create an enrollment token with the elasticsearch-create-enrollment-token tool on any existing node in your cluster. You can then start a new node with the --enrollment-token parameter so that it joins an existing cluster.

Elasticsearch loads its configuration from the %ES_HOME%\config\elasticsearch.yml file by default. The format of this config file is explained in Configuring Elasticsearch.

Any settings that can be specified in the config file can also be specified on the command line, using the -E syntax as follows:

.\bin\elasticsearch.bat -Ecluster.name=my_cluster -Enode.name=node_1

You can test that your Elasticsearch node is running by sending an HTTPS request to port 9200 on localhost:

curl --cacert %ES_HOME%\config\certs\http_ca.crt -u elastic:$ELASTIC_PASSWORD https://localhost:9200 

The call returns a response like this:

{
  "name" : "Cp8oag6",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "AT69_T_DTp-1qgIJlatQqA",
  "version" : {
    "number" : "9.0.0-SNAPSHOT",
    "build_type" : "tar",
    "build_hash" : "f27399d",
    "build_flavor" : "default",
    "build_date" : "2016-03-30T09:51:41.449Z",
    "build_snapshot" : false,
    "lucene_version" : "10.0.0",
    "minimum_wire_compatibility_version" : "1.2.3",
    "minimum_index_compatibility_version" : "1.2.3"
  },
  "tagline" : "You Know, for Search"
}

You can install Elasticsearch as a service that runs in the background or starts automatically at boot time without user interaction.

C:\Program Files\elasticsearch-9.0.0-beta1\bin>elasticsearch-service.bat

Usage: elasticsearch-service.bat install|remove|start|stop|manager [SERVICE_ID]

When you start Elasticsearch for the first time, TLS is configured automatically for the HTTP layer. A CA certificate is generated and stored on disk at:

%ES_HOME%\config\certs\http_ca.crt

The hex-encoded SHA-256 fingerprint of this certificate is also output to the terminal. Any clients that connect to Elasticsearch, such as the Elasticsearch Clients, Beats, standalone Elastic Agents, and Logstash must validate that they trust the certificate that Elasticsearch uses for HTTPS. Fleet Server and Fleet-managed Elastic Agents are automatically configured to trust the CA certificate. Other clients can establish trust by using either the fingerprint of the CA certificate or the CA certificate itself.

If the auto-configuration process already completed, you can still obtain the fingerprint of the security certificate. You can also copy the CA certificate to your machine and configure your client to use it.

Copy the fingerprint value that’s output to your terminal when Elasticsearch starts, and configure your client to use this fingerprint to establish trust when it connects to Elasticsearch.

If the auto-configuration process already completed, you can still obtain the fingerprint of the security certificate by running the following command. The path is to the auto-generated CA certificate for the HTTP layer.

openssl x509 -fingerprint -sha256 -in config/certs/http_ca.crt

The command returns the security certificate, including the fingerprint. The issuer should be Elasticsearch security auto-configuration HTTP CA.

issuer= /CN=Elasticsearch security auto-configuration HTTP CA
SHA256 Fingerprint=<fingerprint>

If your library doesn’t support a method of validating the fingerprint, the auto-generated CA certificate is created in the following directory on each Elasticsearch node:

%ES_HOME%\config\certs\http_ca.crt

Copy the http_ca.crt file to your machine and configure your client to use this certificate to establish trust when it connects to Elasticsearch.

The .zip package is entirely self-contained. All files and directories are, by default, contained within %ES_HOME% — the directory created when unpacking the archive.

This is very convenient because you don’t have to create any directories to start using Elasticsearch, and uninstalling Elasticsearch is as easy as removing the %ES_HOME% directory. However, it is advisable to change the default locations of the config directory, the data directory, and the logs directory so that you do not delete important data later on.
