Elasticsearch is a powerful search engine based on the Lucene library. It’s widely used for full-text search and analysis. In this guide, we will walk you through the installation and configuration of Elasticsearch on Rocky Linux 8.<\/p>\n
Before installing Elasticsearch, it’s important to update your system:<\/p>\n
sudo dnf update -y<\/code><\/pre>\nStep 2: Install Java<\/h2>\n
Elasticsearch requires Java. You can install OpenJDK with the following command:<\/p>\n
sudo dnf install java-11-openjdk -y<\/code><\/pre>\nStep 3: Add the Elasticsearch Repository<\/h2>\n
Add the Elasticsearch GPG key:<\/p>\n
sudo rpm --import https:\/\/artifacts.elastic.co\/GPG-KEY-elasticsearch<\/code><\/pre>\nThen, create a new repo file:<\/p>\n
echo \"[elasticsearch-8.x]\r\nname=Elasticsearch repository for 8.x packages\r\nbaseurl=https:\/\/artifacts.elastic.co\/packages\/8.x\/yum\r\ngpgcheck=1\r\ngpgkey=https:\/\/artifacts.elastic.co\/GPG-KEY-elasticsearch\r\nenabled=1\" | sudo tee \/etc\/yum.repos.d\/elasticsearch.repo<\/code><\/pre>\nStep 4: Install Elasticsearch<\/h2>\n
Now you can install Elasticsearch with the following command:<\/p>\n
sudo dnf install elasticsearch -y<\/code><\/pre>\nStep 5: Start and Enable Elasticsearch Service<\/h2>\n
Start the Elasticsearch service and enable it to start on boot:<\/p>\n
sudo systemctl start elasticsearch\r\nsudo systemctl enable elasticsearch<\/code><\/pre>\nStep 6: Verify the Installation<\/h2>\n
To verify that Elasticsearch is running, use the following command:<\/p>\n
curl -X GET \"localhost:9200\/\"<\/code><\/pre>\nYou should see a JSON response with information about your Elasticsearch instance.<\/p>\n
Step 7: Configure Elasticsearch (Optional)<\/h2>\n
You can configure Elasticsearch by editing the configuration file located at \/etc\/elasticsearch\/elasticsearch.yml<\/code>. Here, you can set cluster name, node name, network settings, and more.<\/p>\nConclusion<\/h2>\n
You’ve successfully installed and configured Elasticsearch on Rocky Linux 8. You can now use it for your applications.<\/p>\n
