多服务器的日志合并统计—cronolog+awstats

1.下载安装cronolog
http://cronolog.org/download/index.html
—>  tar … && cd …&& ./configure && make && make install

2.awstats
可以参考我的awstats安装配置笔记
http://blog.zhangjianfeng.com/?p=317

3.配置http.conf
    CustomLog "|/usr/local/sbin/cronolog  /company/logs/apache/web1_access_log.%Y%m%d" combined
   …apachectl restart

4.最后就是把各台服务器的日志先同步到awstats服务器上,进行日志合并
  sort -m -t " " -k 4 -o log_all log1 log2 log3
  注释： -m: 使用 merge优化算法

5.把合并后的日志交给awstats分析即可 

 附:cronolog详细参数意义:
