Install Wazuh components using the assisted method

Installing the Wazuh indexer

Install and configure the Wazuh indexer nodes on a 64-bit (x86_64/AMD64 or AARCH64/ARM64) architecture.

The following dependencies must be installed on the Wazuh indexer nodes.

1. Run the multi-node assisted method with the --offline-installation to perform an offline installation. Use the option --wazuh-indexer and the node name to install and configure the Wazuh indexer. The node name must be the same one used in config.yml for the initial configuration, for example, node-1.

   # bash wazuh-install.sh --offline-installation --wazuh-indexer node-1
   

   Repeat this step for every Wazuh indexer node in your cluster. Then proceed with initializing your multi-node cluster in the next step.

2. Run the Wazuh assisted installation option --start-cluster on any Wazuh indexer node to load the new certificates information and start the cluster.

   # bash wazuh-install.sh --offline-installation --start-cluster
   

   Note

   You only have to initialize the cluster once, there is no need to run this command on every node.

Testing the cluster installation

1. Run the following command to get the admin password:

   # tar -axf wazuh-install-files.tar wazuh-install-files/wazuh-passwords.txt -O | grep -P "\'admin\'" -A 1
   

2. Run the following command to confirm that the installation is successful. Replace <ADMIN_PASSWORD> with the password gotten from the output of the previous command. Replace <WAZUH_INDEXER_IP_ADDRESS> with the configured Wazuh indexer IP address:

   # curl -k -u admin:<ADMIN_PASSWORD> https://<WAZUH_INDEXER_IP_ADDRESS>:9200
   

   {
     "name" : "node-1",
     "cluster_name" : "wazuh-cluster",
     "cluster_uuid" : "095jEW-oRJSFKLz5wmo5PA",
     "version" : {
       "number" : "7.10.2",
       "build_type" : "rpm",
       "build_hash" : "db90a415ff2fd428b4f7b3f800a51dc229287cb4",
       "build_date" : "2023-06-03T06:24:25.112415503Z",
       "build_snapshot" : false,
       "lucene_version" : "9.6.0",
       "minimum_wire_compatibility_version" : "7.10.0",
       "minimum_index_compatibility_version" : "7.0.0"
     },
     "tagline" : "The OpenSearch Project: https://opensearch.org/"
   }
   

3. Verify that the cluster is running correctly. Replace <WAZUH_INDEXER_IP_ADDRESS> and <ADMIN_PASSWORD> in the following command, then execute it:

   # curl -k -u admin:<ADMIN_PASSWORD> https://<WAZUH_INDEXER_IP_ADDRESS>:9200/_cat/nodes?v
   

Installing the Wazuh server

1. Run the assisted method with --offline-installation to perform an offline installation. Use the option --wazuh-server followed by the node name to install the Wazuh server. The node name must be the same one used in config.yml for the initial configuration, for example, wazuh-1.

   # bash wazuh-install.sh --offline-installation --wazuh-server wazuh-1
   

Your Wazuh server is now successfully installed. Repeat this step on every Wazuh server node.

Installing the Wazuh dashboard

The following dependencies must be installed on the Wazuh dashboard node.

1. Run the assisted method with --offline-installation to perform an offline installation. Use the option --wazuh-dashboard and the node name to install and configure the Wazuh dashboard. The node name must be the same one used in config.yml for the initial configuration, for example, dashboard.

   # bash wazuh-install.sh --offline-installation --wazuh-dashboard dashboard
   

   The default TCP port for the Wazuh web user interface (dashboard) is 443. You can change this port using the optional parameter -p|--port <PORT_NUMBER>. Some recommended ports are 8443, 8444, 8080, 8888, and 9000.

   Once the assistant finishes the installation, the output shows the access credentials and a message that confirms that the installation was successful.

   INFO: --- Summary ---
   INFO: You can access the web interface https://<WAZUH_DASHBOARD_IP_ADDRESS>
      User: admin
      Password: <ADMIN_PASSWORD>
   
   INFO: Installation finished.
   

   You now have installed and configured Wazuh. All passwords generated by the Wazuh installation assistant can be found in the wazuh-passwords.txt file inside the wazuh-install-files.tar archive. To print them, run the following command:

   # tar -O -xvf wazuh-install-files.tar wazuh-install-files/wazuh-passwords.txt
   

2. Access the Wazuh web interface with your admin user credentials. This is the default administrator account for the Wazuh indexer and it allows you to access the Wazuh dashboard.

   • URL: https://<WAZUH_DASHBOARD_IP_ADDRESS>

   • Username: admin

   • Password: <ADMIN_PASSWORD>

   When you access the Wazuh dashboard for the first time, the browser shows a warning message stating that the certificate was not issued by a trusted authority. An exception can be added in the advanced options of the web browser. For increased security, the root-ca.pem file previously generated can be imported to the certificate manager of the browser instead. Alternatively, a certificate from a trusted authority can be configured.
