How to Get the Yum Log on Red Hat or CentOS
The yum log on CentOS/Red Hat Linux servers records package management activities, such as installations, updates, and removals. These logs can help troubleshoot or track changes to your system.
Location of Yum Logs
- Yum logs are stored in the /var/log directory.
- Log file: /var/log/yum.log
Viewing Yum Logs
To view the log, you can use the tail command. For example:
tail -n 10 /var/log/yum.log
This command displays the last 10 entries in the yum log.

- Erased: The package was removed from the server.
