Log Rotation and Archiving
Implement `logrotate` to manage log file sizes, prevent disk exhaustion, and ensure efficient log archiving policies.
Why Log Rotation Matters
Server logs are essential for debugging and monitoring, but they can grow very large over time. If left unchecked, they can quickly fill up your disk space, leading to server instability or even crashes.
This is where log rotation comes in. It's a critical process for managing log file sizes efficiently.
Introducing `logrotate` Utility
Linux systems use a utility called logrotate to automate the management of log files. It's designed to:
- Rotate logs (rename old ones)
- Compress old logs to save space
- Remove ancient log files
- Run custom scripts after rotation
Most Linux distributions have logrotate pre-installed and configured to run daily via a cron job.
