DannyBoyCentOS,

You will benefit from thinking about what you are saying about log files.

Code:

Neo: Rebooting does not automatically delete log-files on normally configured Linux systems., FYI.

DannyBoyCentOS:  What does, then?

Any system which would automatically delete log files on reboot would be a seriously misconfigured system.

Log files are the single most important tool any system administrator has to deal with configuration errors, security breaches, system errors, access control issues, database errors, and more.

Without logging "all is lost".... as one might say, so no normally configured Linux system automatically deletes a single log file during the boot process. When you post like this, an experienced Linux user like me (over two decades of Linux system admin) can only conclude you have very little experience on a server. So let me explain to you again.

Log files should never be automatically deleted on reboot because that means anytime the system reboots, all that logging information would be lost; and a server can reboot for a variety of reasons. Log files are generally rotated and compressed and saved by the system; and then they are generally archived for a certain period of time, and then eventually deleted manually. The could be deleted automatically after some set period of time, but that should normally be a few weeks out (actually it depends on the size of storage, system criticality, system usages and other site specific factors).

In your output, the big files I see are (mysql) dump files and backups. These are not log files, they are backups and dumps. Normally these files can get very big very quickly and need to be actively managed. I manage these on my servers by moving them to an archive site (generally another servers for that specific server); but how you choose to do that is entirely up to you.

Based on what I have seen in your output so far (which admittedly I did not spend too much time on it), the big files you have are .sql and .zip files. If you need disk space, move these to another disk, another server, the cloud or where ever you archive your large files, dumps and backups; and then decide what to keep and what to delete.

Cheers.
