Installing Wazuh agent

  1. Adding the Wazuh repository:

# rpm --import http://packages.wazuh.com/key/GPG-KEY-WAZUH-5
# cat > /etc/yum.repos.d/wazuh.repo <<\EOF
[wazuh_repo]
gpgcheck=1
gpgkey=http://packages.wazuh.com/key/GPG-KEY-WAZUH-5
enabled=1
name=Wazuh repository
baseurl=http://packages.wazuh.com/3.x/yum/5/$basearch/
protect=1
EOF

  1. On your terminal, install the Wazuh agent. You can choose an installation or a deployment:

  1. Installation:

# yum install wazuh-agent-3.10.2-1

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.

  1. Deployment:

You can automate the agent registration and configuration using variables. It is necessary to define at least the variable WAZUH_MANAGER. The agent will use this value to register and it will be the assigned manager for forwarding events.

# WAZUH_MANAGER="10.0.0.2" yum install wazuh-agent-3.10.2-1

See the following document for additional automated deployment options: deployment variables.

  1. (Optional) Disable the Wazuh repository:

We recommend maintaining the Wazuh manager version greater or equal to that of the Wazuh agents. As a result, we recommended disabling the Wazuh repository in order to prevent accidental upgrades. To do this, use the following command:

# sed -i "s/^enabled=1/enabled=0/" /etc/yum.repos.d/wazuh.repo

Alternatively, if you want to download the wazuh-agent package directly, or check the compatible versions, you can do it from here.

Uninstall

To uninstall the agent:

# yum remove wazuh-agent

There are files marked as configuration files. Due to this designation, the package manager doesn't remove those files from the filesystem. The complete files removal action is a user responsibility. It can be done by removing the folder /var/ossec.
