使用
cronolog可以格式化日志文件的格式，比如按时间分割，易于管理和分析。
cronolog的安装配置非常简单，简要说明如下:
1.下载软件
http://cronolog.org/download/index.html
2.解压缩
gzip -d cronolog-1.6.2.tar.gz
tar xf cronolog-1.6.2.tar
2.进入相应的目录 ./configure
3.make
4.make install
5.修改apache配置文件
以下是我的安装日志，供大家参考:

安装完成以后需要对apache进行适当配置，修改httpd.conf文件，主要注意以下几点:
1.自定义日志格式
CustomLog "|/usr/local/sbin/cronolog /opt/apache/logs/access_log.%Y%m%d" combined
2.如果存在多个虚拟站点
可以考虑在VirtualHost进行相应设置
| ServerAdmin webmaster@dummy-host.example.com DocumentRoot /www/docs/dummy-host.example.com ServerName dummy-host.example.com ErrorLog logs/dummy-host.example.com-error_log CustomLog logs/dummy-host.example.com-access_log common |
我的www.eygle.com存在多个子站点，但是都使用了同一个日志文件
配置后生成日志文件的效果:
| [root@eygle logs]# ls -l access_log.20041226 -rw-r--r-- 1 root root 110425 Dec 26 09:10 access_log.20041226 |
