Using rotatelogs to manage Logs in Apache (xampp)

While performing a routine XAMPP (under Linux) healthy check, I've found out some log files had grown up to about 8GB. This might cause the system to slow down. Searching for a solution from the net lead me to this, rotatelogs. To use this rotatelogs it needs to be piped in the XAMPP httpd.conf which is located at /opt/lampp/etc/httpd.conf. So I comment out the 2 original lines and add 2 lines with rotatelogs piped to them like below;

#ErrorLog logs/error_log
ErrorLog "|bin/rotatelogs logs/error_log 5M"
...
#CustomLog logs/access_log common
CustomLog "|bin/rotatelogs logs/access_log 5M" common


Next is to restart the XAMPP by doing ./lampp restart (XAMPP for Linux). Unfortunately it failed and when I observed the error.log it shows;

piped log program 'bin/rotatelogs... failed unexpectedly


Maybe the path is wrong. Next try is to use full path by replace those rotatelogs piped lines with below;

#ErrorLog logs/error_log
ErrorLog "|/opt/lampp/bin/rotatelogs /opt/lampp/logs/error_log 5M"
...
#CustomLog logs/access_log common
CustomLog "|/opt/lampp/bin/rotatelogs /opt/lampp/logs/access_log 5M" common


Finally it works. No error in error_log found. New log file will be created whenever it reach 5MB size. Whenever it switch to the new log file, a unixtime will be appended to the log file name like below;

-rw-r--r-- 1 root root 22713 Jul 27 10:10 access_log.1280196529
-rw-r--r-- 1 root root 4989 Jul 27 10:21 access_log.1280197231
-rw-r--r-- 1 root root 725 Jul 27 10:20 error_log.1280197229


Log file size above is not 5MB yet but when I restart XAMPP, new log file is created. But I'm thinking, what if I don't want to keep all logs, just rotate them weekly. So I try this;

#ErrorLog logs/error_log
ErrorLog "|/opt/lampp/bin/rotatelogs /opt/lampp/logs/error_log.%a 86400"
...
#CustomLog logs/access_log common
CustomLog "|/opt/lampp/bin/rotatelogs /opt/lampp/logs/access_log.%a 86400" common


The new log file name now looks something like below.

-rw-r--r-- 1 root root 625 Jul 27 12:04 error_log.Tue
-rw-r--r-- 1 root root 1941 Jul 27 12:04 access_log.Tue


They will rotate in 24 hours (86400 secs) with a 3-character weekday name appended to them. I assume they will rotate and replace just like I plan in 1 week time, I hope so. :-)
