Apache rotate Access and Error logs Windows

Question

How can I rotate the Apache Access and Error logs on a Window 2000 box?

I include my batch file below as an answer.

Is there a way of doing this directly via the

Answer 1

I wrote a vbs for a Windows 2003 box once. It uses zip.exe for compression (found at info-zip.org) and rotates apache logs and php logs. Logs are rotated when larger than MAX_SIZE. It deletes the oldest logs if log count passes MAX_ROTATIONS.

Please provide feedback on the script.

I've a little bit extend the the bat-script. You can use it for english and german dates. You will need 7za.exe at the same directory like script. The log-dir and -files for rotation are explicitly settable.

Here's the DOS batch file, modified as annotated. I run it weekly and it keeps 8 weeks of zipped backups. You'll need to install 7 zip.

I haven't parametrised the paths, feel free to.

Answer 4

As stated I don't think this is strictly a programming question, but AFAIK there is no built-in functionality in Apache to support log rotation. There's a standard utility on unix systems called logrotate, so that functionality would be redundant on those systems.

If you rephrase your question to ask how you can write a batch file to handle Apache log rotation on Windows 2000, then answer yourself with your batch file source, that might be helpful to others.
