安装日志轮询工具cronolog：
[root@bqh-119 tools]# tar xf cronolog-1.6.2.tar.gz [root@bqh-119 tools]# cd cronolog-1.6.2 [root@bqh-119 cronolog-1.6.2]# ./configure make make install [root@bqh-119 cronolog-1.6.2]# ll /usr/local/sbin/cronolog -rwxr-xr-x 1 root root 40486 7月 15 21:55 /usr/local/sbin/cronolog
按天轮询：（生产环境常见用法，推荐使用）：
CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_blog_%Y%m%d.log" combined CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_bbs_%Y%m%d.log" combined
注：按天记录日志，日志不会自动覆盖。
按小时轮询：（较常见用法）
CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_blog_%Y%m%d%H.log" combined CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_bbs_%Y%m%d%H.log" combined
注：适合短时间分析的apache详细日志信息。
按周轮询：（较常见用法）
CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_blog_%w.log" combined CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_bbs_%w.log" combined ----------------------------------------------------------------------------------------------↓↓↓分目录按周记录日志 CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/%w/access_blog_%w.log" combined CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/%w/access_bbs_%w.log" combined
注：每周循环覆盖；如果需要保留少量日志，供sa等使用，不作为特殊其他信息分析等，可以按周轮询，免去担心空间问题。
按月轮询：
CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_blog_%Y%m.log" combined CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_bbs_%Y%m.log" combined
按天+按小时轮询：
CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_blog_%Y%m%d.log" combined CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_blog_%Y%m%d%H.log" combined CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_bbs_%Y%m%d.log" combined CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_bbs_%Y%m%%d%H.log" combined
.....可以自由组合来轮询日志。
下面以按天轮询日志的测试配置：
[root@bqh-119 extra]# vim httpd-vhosts.conf ......以上省略 <VirtualHost *:80> ServerAdmin 1147076062@qq.com DocumentRoot "/var/html/blog" ServerName blog.bqh123.com ServerAlias bg.bqh123.com ErrorLog "logs/blog-error_log" CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_blog_%Y%m%d.log" combined </VirtualHost> <VirtualHost *:80> ServerAdmin 1147076062@qq.com DocumentRoot "/var/html/bbs" ServerName bbs.bqh123.com ServerAlias bs.bqh123.com ErrorLog "logs/bbs-error_log" CustomLog "|/usr/local/sbin/cronolog /application/apache/logs/access_bbs_%Y%m%d.log" combined </VirtualHost>
刷新配置：
[root@bqh-119 extra]# vim httpd-vhosts.conf [root@bqh-119 extra]# ../../bin/apachectl -t Syntax OK [root@bqh-119 extra]# ../../bin/apachectl graceful
访问测试，并查看日志：
