Install Fleet-managed Elastic Agentsedit

These steps assume you’re running a fresh installation. If Elastic Agent is already running on your system, and you want to upgrade to a new version, see Upgrade Elastic Agents.

If you’re a new user, instead of following the steps described here, read our quick start guides:


  • Fleet is currently only available to users with the superuser role.
  • A Fleet Server must be running in a location accessible to the Elastic Agent. See Fleet Server.
  • To use Fleet, Elastic Agents must have a direct network connection to Fleet Server and Elasticsearch.
  • An internet connection is required for Kibana to download integration packages from the Elastic Package Registry. Make sure the Kibana server can connect to on port 443.
  • You must have an enrollment token generated by Fleet. Don’t have a Fleet enrollment key? Read Fleet enrollment tokens to learn how to get one from Fleet.
  • You must have the host and IP where Fleet Server is running. Not sure where it’s running? Look at the Fleet settings in Kibana.
  • If you’re running Elastic Agent 7.9 or earlier, stop the agent and manually remove it from your host.

Installation stepsedit

You can install only a single Elastic Agent per host.

To install an Elastic Agent and enroll it in Fleet:

  1. On the machine where you’ll run Elastic Agent, download and extract the installation package.

    curl -L -O
    tar xzvf elastic-agent-7.17.21-darwin-x86_64.tar.gz

    See the download page for other installation options.

  2. On the Agents tab in Fleet, click Add agent.
  3. Under Enroll in Fleet, follow the in-product installation steps (skip the download step if you’ve already done it).

    add agent

    See the download page for other installation options.


  • Use the default agent policy to get started quickly. This policy includes a system integration for collecting logs and metrics from the host system. You can change the policy later.
  • On macOS, Linux (tar package), and Windows, run the install command to install Elastic Agent as a managed service, enroll it in Fleet, and start the service. The DEB and RPM packages include a service unit for Linux systems with systemd, so use the enroll command instead of install.

    You must run this command as the root user because some integrations require root privileges to collect sensitive data.

    cd elastic-agent-7.17.21-darwin-x86_64
    sudo ./elastic-agent install -f --url=<fleet_server_url> --enrollment-token=<enrollment_token>  

    fleet_server_url is the host and IP where Fleet Server is running, and enrollment_token is the enrollment token acquired from Fleet.

    Omit -f to run an interactive installation.

    If you see an "x509: certificate signed by unknown authority" error, you might be trying to enroll in a Fleet Server that uses self-signed certs. To fix this problem in a non-production environment, pass the --insecure flag. For more information, refer to the troubleshooting guide.

    Refer to Installation layout for the location of installed Elastic Agent files.

Because Elastic Agent is installed as an auto-starting service, it will restart automatically if the system is rebooted.

To confirm that Elastic Agent is installed and running, go to the Agents tab in Fleet. Notice that the Default policy is assigned to the agent.
