Introduction
A report-export service cannot start because its small configuration file contains an invalid port value. The service log explains the accepted range.
The preceding guided lab practiced the same recovery pattern: inspect status, read the journal, repair one configuration value, reset the failed state, and start the service.
Return the Service to Active
Current Situation
labex-report-export.service is failed. It reads one PORT assignment from /etc/labex-report-export.conf.
Scope
- Use service status and journal evidence to understand the failure.
- Change only the invalid
PORTvalue. - Choose a numeric port from
1024through65535. - Do not edit the unit file or unrelated services.
Your Goal
Leave labex-report-export.service active with a valid configured port.
Acceptance Criteria
systemctl is-active labex-report-export.servicereportsactive./etc/labex-report-export.confcontains one in-range numericPORTvalue.
Hints
Where should diagnosis begin?
Use the same systemctl status and unit-specific journalctl commands practiced in the guided lab. The failure message states what is invalid.
Summary
You used service evidence to repair one invalid value and return one failed unit to service.
