Amazon Linux from sources

This guide describes how to install the Wazuh agent from source code for Amazon Linux 1 or greater. For other operating systems or Linux distributions, please check the list: Install Wazuh agent.

Installing Wazuh agent

Note

All the commands described below need to be executed with root user privileges. Since Wazuh 3.5 it is necessary to have internet connection when following this process.

  1. Install development tools and compilers. In Linux this can easily be done using your distribution's package manager:

    # yum install make gcc policycoreutils-python automake autoconf libtool

  2. Download and extract the latest version:

    # curl -Ls https://github.com/wazuh/wazuh/archive/v3.11.4.tar.gz | tar zx

  3. Run the install.sh script. This will run a wizard that will guide you through the installation process using the Wazuh sources:

    # cd wazuh-*
# ./install.sh

    If you have previously compiled for another platform, you must clean the build using the Makefile in src:

    # cd wazuh-*
# make -C src clean
# make -C src clean-deps

    Note

    During the installation, users can decide the installation path. Execute the ./install.sh and select the language, set the installation mode to agent, then set the installation path (Choose where to install Wazuh [/var/ossec]). The default path of installation is /var/ossec. A commonly used custom path might be /opt. When choosing a different path than the default, if the directory already exist the installer will ask if delete the directory or if installing Wazuh inside. You can also run an unattended installation.

  4. The script will ask about what kind of installation you want. Type agent in order to install a Wazuh agent:

1- What kind of installation do you want (manager, agent, local, hybrid or help)? agent

Now that the agent is installed, the next step is to register and configure it to communicate with the manager. For more information about this process, please visit the document: user manual.
