Filebeat is a lightweight shipper for forwarding and centralizing log data. While it’s a valuable tool for many administrators, there may come a time when you need to uninstall it from your Ubuntu system. This guide will walk you through the steps to safely and completely remove Filebeat from your Ubuntu server or desktop.
Before diving into the uninstallation process, it’s essential to understand the different components of Filebeat and how they interact with your system. Filebeat typically consists of the main binary, configuration files, and data directories. When uninstalling, it’s crucial to ensure that all these components are removed to prevent any potential issues in the future.
Let’s get started.
Step 1: Stop the Filebeat Service
Before uninstalling any software, it’s a good practice to stop its services to ensure a smooth removal process.
sudo systemctl stop filebeat
Step 2: Uninstall Filebeat
Now that the service is stopped, you can proceed to uninstall Filebeat using the package manager.
sudo apt-get purge filebeat
This command will remove Filebeat and its configuration files.
Step 3: Remove Data Directories
Filebeat might have created data directories during its operation. To ensure a complete removal, delete these directories.
sudo rm -r /var/lib/filebeat sudo rm -r /etc/filebeat
Step 4: Optional – Remove Related Repositories
If you added the Elastic repository when you installed Filebeat, you might want to remove it as well.
sudo rm /etc/apt/sources.list.d/elastic-7.x.list
Then, update the package database:
sudo apt-get update
Step 5: Verify Uninstallation
To ensure that Filebeat has been completely removed, you can try running:
filebeat version
If the system responds with a message indicating that the command ‘filebeat’ is not found, then the uninstallation was successful.
