[轉貼]如何在 Apache 設定 (Custom Log) Access Log 與 Error Log
- Apache Log 檔中包含了很多的資訊,包括哪個 IP 在存取你的網頁、哪個時間是尖峰時刻、用什麼瀏覽器來你的網站的、是直接存取還是間接存取你的網頁、等等狀態。
- 編輯 http.conf 檔
[root@host ~]$ cd /etc/httpd/conf [root@host ~]$ vim httpd.conf
- 找到根目錄及 LOG 位置
ServerRoot "/etc/httpd" #Apache的根目錄位置 ErrorLog "logs/error_log" #Error Log所在位置 CustomLog "logs/access_log common #Access Log所在位置 /* 如果原本是 "#" 註解掉的,記得要把它解開喔。 */
- 設定符合你的 LOG 檔
#CustomLog "logs/access_log" common /* 將這一行注解掉 */ CustomLog "|/usr/sbin/rotatelogs /etc/httpd/logs/access_log.%Y-%m-%d 86400" common /* 將 rotatelogs 寫到你預設的 LOG 格式 */ #access_log 命名結果為 access_log.2013-06-06 #86400 代表記錄一天
- LOG 格式
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%{X-Forwarded-For}i %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" common #這邊可以設定你想要用的 log 格式
- 設定 VirtualHost 的 LOG
/* 先把 http.conf 的 LOG 全部註解掉! */ [root@host ~]$ cd /etc/httpd/conf.d [root@host ~]$ vim vh.conf NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /var/www/html/site1 ServerName site1.com.tw CustomLog "|/usr/sbin/rotatelogs /etc/httpd/logs/site1/access_log.%Y-%m-%d 86400" common ErrorLog "|/usr/sbin/rotatelogs /etc/httpd/logs/site1/error_log.%Y-%m-%d 86400" <VirtualHost *:80> DocumentRoot /var/www/html/site2 ServerName site2.com.tw CustomLog "|/usr/sbin/rotatelogs /etc/httpd/logs/site2/access_log.%Y-%m-%d 86400" common ErrorLog "|/usr/sbin/rotatelogs /etc/httpd/logs/site2/error_log.%Y-%m-%d 86400"
- 網站使用 CDN 的 LogFormat
LogFormat "%{X-Forwarded-For}i %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" common
/* 網站若使用CDN,access_log 記錄 ip 會有問題 */
- 小提醒
CustomLog “|/usr/sbin/rotatelogs /etc/httpd/logs/site1/access_log.%Y-%m-%d 1M” common
# 是指 LOG 檔達到 1M 就進行 Log Rotate
