Optional. Install the following dependencies only when compiling the CPython from sources. Since v4.2.0, make deps TARGET=server will download a portable version of CPython ready to be installed. Nevertheless, you can download the CPython sources by adding the PYTHON_SOURCE flag when running make deps.

To install the required dependencies to build the python interpreter, follow these steps:

# yum install epel-release yum-utils -y
# yum-builddep python34 -y

# echo "deb-src http://archive.ubuntu.com/ubuntu $(lsb_release -cs) main" >> /etc/apt/sources.list
# apt-get update
# apt-get build-dep python3 -y

Installing the Wazuh manager

1. Download and extract the latest version:

   # curl -Ls https://github.com/wazuh/wazuh/archive/v4.9.2.tar.gz | tar zx
   # cd wazuh-4.9.2
   

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

   # make -C src clean
   # make -C src clean-deps
   

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

   Warning

   If you want to enable the database output, check out this section before running the installation script.

   # ./install.sh
   

   The initial run might take some time as it downloads and processes the vulnerability detection content. To speed up this process, you can set the DOWNLOAD_CONTENT environment variable to y beforehand. The adjusted command downloads a pre-prepared database during installation.

   # DOWNLOAD_CONTENT=y ./install.sh
   

4. When the script asks what kind of installation you want, type manager to install the Wazuh manager:

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

   Note

   During the installation, users can decide the installation path. Execute the ./install.sh and select the language, set the installation mode to manager, 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.

   Warning

   Be extremely careful not to select a critical installation directory if you choose a different path than the default. If the directory already exists, the installer will ask to delete the directory or proceed by installing Wazuh inside it.

5. The installer asks if you want to start Wazuh at the end of the installation. If you choose not to, you can start it later with:

   SystemdSysV init

   # systemctl start wazuh-manager
   

Installing other Wazuh components

Once the Wazuh manager is installed from sources, you may install the Wazuh indexer, Filebeat, and the Wazuh dashboard following the Installation guide.

Uninstall

1. To uninstall the Wazuh manager, set WAZUH_HOME with the current installation path:

   # WAZUH_HOME="/WAZUH/INSTALLATION/PATH"
   

2. Stop the service:

   # service wazuh-manager stop 2> /dev/null
   

3. Stop the daemon:

   # $WAZUH_HOME/bin/wazuh-control stop 2> /dev/null
   

4. Remove the installation folder and all its content:

   # rm -rf $WAZUH_HOME
   

5. Delete the service:

   SysV initSystemd

   # [ -f /etc/rc.local ] && sed -i'' '/wazuh-control start/d' /etc/rc.local
   # find /etc/{init.d,rc*.d} -name "*wazuh*" | xargs rm -f

   # userdel wazuh 2> /dev/null
   # groupdel wazuh 2> /dev/null
