InfluxDB is a popular time-series database used for monitoring, event data, and real-time analytics. While it’s a powerful tool, there might be instances where you need to uninstall it from your Ubuntu server.
Whether you’re migrating to a different solution or simply cleaning up, this guide will walk you through the process step by step.
Let’s get started.
Step 1: Backup Your Data
Before uninstalling any software, especially databases, it’s crucial to backup any essential data. InfluxDB stores its data in the /var/lib/influxdb/ directory by default.
sudo tar cvzf influxdb-backup.tar.gz /var/lib/influxdb/
This command creates a backup archive named influxdb-backup.tar.gz.
Step 2: Stop the InfluxDB Service
Before uninstalling, ensure that the InfluxDB service is stopped.
sudo systemctl stop influxdb
Step 3: Remove InfluxDB Packages
Now, you can uninstall InfluxDB using the package manager.
sudo apt-get purge influxdb
This command will remove the InfluxDB package and its configuration files.
Step 4: Remove Data and Configuration Directories
To remove all data and configuration files related to InfluxDB:
sudo rm -rf /var/lib/influxdb/ sudo rm -rf /etc/influxdb/
Step 5: Remove InfluxDB User and Group
InfluxDB creates its own user and group. To remove them:
sudo userdel -r influxdb sudo groupdel influxdb
