Install Elasticsearch on a Dedicated Server

Procedure

On the server on which you want to install Elasticsearch, download and install OpenJDK V1.8.0_111 or Oracle JDK V1.8.0_73.

Important: Java versions higher than V1.8.0_XX are currently not supported. You may need to disable automatic updates for Java. For more information, refer to the Java Update Options topic in the Java website.
Create a JAVA HOME system environment variable for the installed version as shown in the following examples:
- Example of system environment variable for OpenJDK V1.8.0_181-b13
  JAVA_HOME=C:\Program Files\Java\java-1.8.0-openjdk-1.8.0.181-1.b13.redhat.windows.x86_64
- Example of system environment variable for Oracle JDK V1.8.0_73
  JAVA_HOME=C:\Program Files\Java\jdk1.8.0_73
Enter the following command to verify the environment variable.
```
echo %JAVA_HOME%
```
Note:
- The JAVA HOME variable should match the full version string of OpenJDK or Oracle JDK that you installed, and its installation location.
- For additional information regarding Java support for Elasticsearch, consult https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html.
Download the zip file for Windows, elasticsearch-6.7.0.zip, from the official Elasticsearch 6.7.0 Downloads page.
Extract the contents of the zip file to C:\ElasticSearch.
Go to C:\ElasticSearch\elasticsearch-6.7.0\config, and then access the elasticsearch.yml file.

In the .yml file, uncomment the following properties, and then modify the values to match those shown here:

cluster.name: apm-cluster
node.name: ${COMPUTERNAME}
path.data: /ProgramData/Meridium/ElasticSearch
path.logs: /ProgramData/Meridium/Logs
bootstrap.memory_lock: true
network.host: 0.0.0.0
http.port: 9200
action.destructive_requires_name: true

Save and close the .yml file.
Select the Start button on Windows, right-click Command Prompt, and then select Run as administrator.
The Command Prompt window appears.
At the command prompt, enter cd C:\ElasticSearch\elasticsearch-6.7.0\bin, and then press Enter.
At the command prompt, enter elasticsearch-service install, and then press Enter.
Elasticsearch is installed.
Access the Microsoft Management Console (services.msc) and perform the following operations for the Elasticsearch service:
- Verify that the service runs as Local System.
- Modify the startup to be Automatic.
- Start the service to verify installation and configuration.

On the server on which Elasticsearch is installed, go to http://localhost:9200/ in a web browser, and ensure that Elasticsearch runs successfully.

A response that is similar to the following sample appears.

{
"name" : "apm-node",
"cluster_name" : "apm-cluster",
"cluster_uuid" : "58cS6NyzQJOLZ8Xr1e3vkg",
"version" : {
"number" : "6.7.0",
"build_hash" : "3adb13b",
"build_date" : "2017-03-23T03:31:50.652Z",
"build_snapshot" : false,
"lucene_version" : "6.4.1"
},

On the server on which Elasticsearch is installed, go to http://[elastic-search-server]:9200/ in a web browser, and ensure that Elasticsearch runs successfully.
A response that is similar to the sample provided in the previous step appears.
On the GE Digital APM server, go to C:\ProgramData\Meridium\MeridiumAppSettings.xml.

As needed, modify the following values.

<!-- Search and Elastic Services -->
<add key="searchServiceUrl" value="http://localhost:9199" />
<add key="elasticServiceUrl" value="http://<name of Elastic Search server>:9200" />

After all third-party services are configured, reset IIS and services on all GE Digital APM App Servers.
