To address this need, you can install wazuh server cluster, an open-source security monitoring platform that combines SIEM, log analysis, intrusion detection, and vulnerability detection into a single unified solution.<\/p>\n\n\n\n<p>Setting up a Wazuh server in a cluster provides high availability, improved performance, and simplified management in distributed environments.<\/p>\n\n\n\n<p>In one of our earlier blogs, we covered the installation of the <strong>Wazuh Indexer<\/strong>, which is responsible for storing and indexing security data collected from agents. In this guide, we\u2019ll focus on how to install the <strong>Wazuh Server<\/strong> in a cluster configuration \u2014 the core engine that receives data from agents, applies rules and decoders, and forwards enriched data to the indexer.<\/p>\n\n\n\n<p>We will be using the official Wazuh installation script, reducing a complex deployment to a few steps.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-small-font-size\">Step 1: Download the Wazuh Installation Script<\/h2>\n\n\n\n<p>First, download the official Wazuh installation script:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>curl -sO https:\/\/packages.wazuh.com\/4.11\/wazuh-install.sh<\/code><\/pre>\n\n\n\n<p>This script simplifies the deployment of Wazuh components including the manager, Filebeat, and required SSL certificates.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-small-font-size\">Step 2: Run the Installation Script<\/h3>\n\n\n\n<p>To install the Wazuh server component, run the script with the &#8211;wazuh-server option followed by the node name (e.g., wazuh-1):<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>bash wazuh-install.sh --wazuh-server wazuh-1<\/code><\/pre>\n\n\n\n<p>This command installs:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wazuh Manager \u2013 Core of the platform, managing agent data and rules.<\/li>\n\n\n\n<li>Filebeat \u2013 For forwarding logs to the Wazuh indexer.<\/li>\n\n\n\n<li>Configuration files and SSL certificates for secure communication.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-small-font-size\">Step 3: Verify the Installation<\/h3>\n\n\n\n<p>Check that the Wazuh Manager service is active:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>systemctl status wazuh-manager<\/code><\/pre>\n\n\n\n<p>Also, Validate Filebeat&#8217;s output configuration by running the below command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>filebeat test output<\/code><\/pre>\n\n\n\n<p>If the output test completes successfully, you will see a result similar to the following:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>elasticsearch: https:\/\/127.0.0.1:9200...\n  parse url... OK\n  connection...\n    parse host... OK\n    dns lookup... OK\n    addresses: 127.0.0.1\n    dial up... OK\n  TLS...\n    security: server's certificate chain verification is enabled\n    handshake... OK\n    TLS version: TLSv1.2\n    dial up... OK\n  talk to server... OK\n  version: 7.10.2<\/code><\/pre>\n\n\n\n<p>A successful output test indicates that Filebeat has been properly configured and is successfully communicating with the Wazuh indexer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-small-font-size\">Conclusion<\/h3>\n\n\n\n<p>Installing a Wazuh server node in a clustered environment is a critical step toward building a scalable and secure infrastructure. By using the Wazuh installation script, much of the complexity is handled automatically \u2014 saving time and ensuring consistency. In future steps, you can expand this setup by adding additional manager nodes and connecting them with indexers and dashboards.<\/p>\n\n\n\n<p>Need help to install Wazuh Server Cluster or expert <a href=\"https:\/\/www.skynats.com\/server-management\/\">server management services<\/a>?
