Elasticsearch java_home Centos | Implementation

by | Mar 11, 2024

Setting up Elasticsearch’s JAVA_HOME on CentOS involves the following steps. As part of our Server Management Service, Bobcares provides answers to all of your questions.

Setting up Elasticsearch’s JAVA_HOME on CentOS

We must run the following steps in order to set up the variable:

1. We must first install Java on the CentOS system. Installing Oracle JDK or OpenJDK is an option. We can use the YUM package manager in order to set up OpenJDK as follows:

elasticsearch java_home centos

2. We need to find the setup directory after setting up Java. The Java executable can be found using the below command. It will produce the path, which usually looks like /usr/bin/java, to the Java executable.

elasticsearch java_home centos

3. We may set the JAVA_HOME environment variable after locating the Java executable. Use a text editor like nano or vi to make changes to the Elasticsearch config file:

elasticsearch java_home centos

To point to the location of the Java setup, add or edit the JAVA_HOME variable.

4. For the changes to take effect, restart the Elasticsearch service after changing JAVA_HOME:

5. By looking through the Elasticsearch logs or sending a query over Elasticsearch’s HTTP API, we may confirm that Elasticsearch is running the correct version of Java:

elasticsearch java_home centos

We should see a JSON response containing details about the Elasticsearch cluster if Elasticsearch is working properly.
