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 Apache config file? I'm currently using the following customlog command to generate daily logs.
CustomLog '|" "*Apache-Path/bin/rotatelogs.exe" "*Apache-Path/logs/backup/internet_access_%d-%m-%y.log" 86400' combined
839
Unzip the apache download and go to the bin folder, and confirm there is a rotatelogs.exe file. Install the server as either a service, or start from the bin folder, and confirm it works.
The log file rotation is implemented using the rotatelogs utility that is provided with httpd. This utility allows you to define when to rotate logs. The rotatelogs utility uses piped logs. This opens an access log file named access_log located at the /var/log/ directory using the log format defined by the name common.
If you want to rotate /var/log/syslog it needs to be listed in a logrotate config file somewhere, and you just run logrotate . If it rotated recently, then logrotate -f to force it to do it again. So, you need that in a file, normally either /etc/logrotate. conf or as a file snippet in /etc/logrotate.
On a Linux server, you can access Apache error logs from var/log/apache2/error. log. You can then log out the errors from the error log file by writing the following command: sudo tail -f /var/log/apache2/error.
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.
