第 3回 Webサーバー設定 ログの設定は httpd. conf ファイルで行います。 Access. Log 207 208 Log. Format "%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i"" combined Log. Format "%h %l %u %t "%r" %>s %b" common 216 217 218 219 220 221 222 # The location and format of the access logfile (Common Logfile Format). # If you do not define any access logfiles within a <Virtual. Host> # container, they will be logged here. Contrariwise, if you *do* # define per-<Virtual. Host> access logfiles, transactions will be # logged therein and *not* in this file. # Custom. Log "logs/access_log" common ※設定する項目によって、logファイルの 肥大化が発生しますので、注意が必要です！ －27 －
