Install Wazuh server with RPM packages

For CentOS/RHEL/Fedora platforms, installing the Wazuh server components entails the installation of the relevant packages after adding the repositories.


Many of the commands described below need to be executed with root user privileges.

Adding the Wazuh repository

The first step to setting up Wazuh is to add the Wazuh repository to your server. If you want to download the wazuh-manager package directly, or check the compatible versions, click here.

To set up the repository, run this command:

# cat > /etc/yum.repos.d/wazuh.repo <<\EOF
name=Wazuh repository

For CentOS-5 and RHEL-5:

# cat > /etc/yum.repos.d/wazuh.repo <<\EOF
name=Wazuh repository

Installing the Wazuh Manager

The next step is to install the Wazuh Manager on your system:

# yum install wazuh-manager-3.4.0-1

Once the process is complete, you can check the service status with:

  1. For Systemd:

# systemctl status wazuh-manager
  1. For SysV Init:

# service wazuh-manager status

Installing the Wazuh API

  1. NodeJS >= 4.6.1 is required in order to run the Wazuh API. If you do not have NodeJS installed or your version is older than 4.6.1, we recommend that you add the official NodeJS repository like this:

# curl --silent --location | bash -

and then, install NodeJS:

# yum install nodejs
  1. Python >= 2.7 is required in order to run the Wazuh API. It is installed by default or included in the official repositories in most Linux distributions.

    To determine if the python version on your system is lower than 2.7, you can run the following:

 # python --version

It is possible to set a custom Python path for the API in ``/var/ossec/api/configuration/config.js``, in case the stock version of Python in your distro is too old:
config.python = [
    // Default installation
        bin: "python",
        lib: ""
    // Package 'python27' for CentOS 6
        bin: "/opt/rh/python27/root/usr/bin/python",
        lib: "/opt/rh/python27/root/usr/lib64"

CentOS 6 and Red Hat 6 come with Python 2.6, however, you can install Python 2.7 in parallel to maintain the older version(s):

  1. For CentOS 6:

# yum install -y centos-release-scl
# yum install -y python27
  1. For RHEL 6:

# yum install python27

You may need to first enable a repository in order to get python27, with a command like this:
#   yum-config-manager --enable rhui-REGION-rhel-server-rhscl
#   yum-config-manager --enable rhel-server-rhscl-6-rpms
  1. Install the Wazuh API. It will update NodeJS if it is required:

# yum install wazuh-api-3.4.0-1
  1. Once the process is complete, you can check the service status with:

  1. For Systemd:

# systemctl status wazuh-api
  1. For SysV Init:

# service wazuh-api status

Installing Filebeat

Filebeat is the tool on the Wazuh server that securely forwards alerts and archived events to the Logstash service on the Elastic Stack server(s).


In a single-host architecture (where Wazuh server and Elastic Stack are installed in the same system), the installation of Filebeat is not needed since Logstash will be able to read the event/alert data directly from the local filesystem without the assistance of a forwarder.

The RPM package is suitable for installation on Red Hat, CentOS and other modern RPM-based systems.

  1. Install the GPG keys from Elastic and then the Elastic repository:

# rpm --import

# cat > /etc/yum.repos.d/elastic.repo << EOF
name=Elasticsearch repository for 6.x packages
  1. Install Filebeat:

# yum install filebeat-6.3.2
  1. Download the Filebeat configuration file from the Wazuh repository. This is pre-configured to forward Wazuh alerts to Logstash:

# curl -so /etc/filebeat/filebeat.yml
  1. Edit the file /etc/filebeat/filebeat.yml and replace ELASTIC_SERVER_IP with the IP address or the hostname of the Elastic Stack server. For example:

    hosts: ["ELASTIC_SERVER_IP:5000"]
  1. Enable and start the Filebeat service:

  1. For Systemd:

# systemctl daemon-reload
# systemctl enable filebeat.service
# systemctl start filebeat.service
  1. For SysV Init:

# chkconfig --add filebeat
# service filebeat start

Next steps

Once you have installed the manager, API and Filebeat (only needed for distributed architectures), you are ready to install Elastic Stack.
