apache日志分离组件cronolog
1.1 概述
apache默认的日志都会记录到一个文件内
如果访问量过多，时间过长，将导致日志堆积，文件变大，影响apache的性能
cronolog是一个用于日志切分的软件,使用管道把输入定位到其他路径保存
1.2 安装
wget http://cronolog.org/download/cronolog-1.6.2.tar.gz
tar xcvf cronolog-1.6.2.tar.gz
cd cronolog-1.6.2
sudo ./configure -–prefix=%INSTALL_DIR%
sudo make install
1.3 使用
修改apache的日志记录
CustomLog “|%INSTALL_DIR%/cronolog %APACHE_HOME%/apache/logs/cronolog/%Y/%m/%d/%H_access_log” combined
ErrorLog “|%INSTALL_DIR%/cronolog %APACHE_HOME%/logs/cronolog/%Y/%m/%d/error_log”
然后需要reload下apache
sudo service apache restart
接下来可以在对应的logs/cronolog里面找到分离开的日志
