Apache log 分割處理用的 mod_log_rotate 此法僅適用於 CustomLog 檔(TransferLog, LogFormat and CookieLog 應也可以)
用法很簡單：
將 mod_log_rotate.so 放到 Apache 的 module 目錄，如 Apache2\modules.
在 httpd.conf 中加上
LoadModule log_rotate_module modules/mod_log_rotate.so
RotateLogs On (打開 log)
RotateLogsLocalTime On (用 local time 算，default 是用 UTC 時間)
RotateInterval 86400 (86400 是 default，也就是一天，這一行不加也可以)
修改 CustomLog 的地方
CustomLog logs/access.log common
改成
CustomLog logs/access_%Y%m%d.log combined
下載 cronolog 作 Apache log 的分割處理 此法僅適用於errorLog 檔 ,(CustomLog 測試無效原因??)
方法, 修改 Apache 設定檔 httpd.conf, 把 default 的
ErrorLog "logs/error.log"
改成
ErrorLog "|c:/bin/cronolog.exe logs/error_%Y%m%d.log"
就好了. 其中 c:/bin/cronolog.exe (這個是 win32 用的) 就是放 cronolog 的目錄, 後面的 logs/access_%Y%m%d.log 是 log 產出的目錄 (logs) 及形式, access_%Y%m%d.log 會生出像 access_20050702.log 這樣的檔名, 每天一個檔案. 別忽略了一開始的 “|” 那是 pipeline 給 cronolog 作處理的意思.
