对于服务器的日常维护来说，日志清理是非常重要的事情，如果残留日志过多则严重浪费磁盘空间同时影响服务的性能。如果用手工方式进行清理，会花费太多时间，并且很多时候难以满足实际要求。例如：如何在每个星期六凌晨3点把超过2G大的日志文件进行切割，保留最新的100M日志记录？

网上没有发觉能满足本座要求的日志切割工具，因此花了一些闲暇时间自己写了一个。由于要在多个平台上使用，为了方便采用 Java 实现。本工具命名为 LogCutter，主要有以下特点：

支持 Linux、Mac 和 Windows 等所有常见操作系统平台

支持命令行交互式运行

支持后台非交互式运行(Linux/MAC 下使用 daemon 进程实现，Windows 用系统 Service 实现)

支持两种日志清理方式(删除日志文件或切割日志文件)

支持对 GB18030、UTF-8、UTF-16LE、UTF-16BE 等常用日志文件类型进行切割(不会发生切掉半个字符的情况)

高度可配置(程序执行周期、要删除的日志文件过期时间、要切割的日志文件阀值和保留大小等均可配置

*******************************************************

一、启动方式

--------------------------------------------------

1) Windows

A) 前台运行: > ./run.bat

B) 后台运行: > ./LogCutter.exe {

-install-demand (安装手动启动服务)

-install-auto (安装自动启动服务)

-start (启动服务)

-stop (停止服务)

-status (查看服务状态)

}

*** 注 ***

@ LogCutter.exe 以 Windows 系统服务的方式运行，安装好后也可以通过 Windows 服务管理器进行管理

@ LogCutter.exe 依赖 JRE 1.6, 因此必须在注册表或环境变量中设置 %JAVA_HOME%

2) Linux / Unix

A) 前台运行: $ ./run.sh

B) 后台运行: $ ./run.sh -d

*** 注 ***

@ 可以设置为开机时自动后台运行，方法如下:

$ vi /etc/rc.d/rc.local

( 加入: ${YOUR_LOGCUTTER_PATH}/run.sh -d )

--------------------------------------------------

二、配置文件

--------------------------------------------------

1) 程序配置文件: ./conf/config.xml

2) 日志配置文件: ./conf/log4j.properties (默认)

--------------------------------------------------

三、环境要求

--------------------------------------------------

1) Java 版 本: JRE 1.6 以上

2) 依赖程序包: dom4j、log4j、juniversalchardet

--------------------------------------------------

run.sh (Mac 平台)

#!/bin/bash

JAVA_HOME="/Library/Java/Home"

CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

JAVA_BIN=$JAVA_HOME/bin

JAVA=$JAVA_BIN/java

APP_PATH="/Users/Kingfisher/MyWork/Java/LogCutter"

APP_CLASSPATH=$APP_PATH/classes

APP_LIBPATH=$APP_PATH/lib

APP_LIBS=$APP_LIBPATH/dom4j-1.6.1.jar:$APP_LIBPATH/log4j-1.2.16.jar:$APP_LIBPATH/juniversalchardet-1.0.3.jar

APP_CONFPATH=$APP_PATH/conf

APP_CONFFILE=$APP_CONFPATH/config.xml

APP_MAIN_CLASS=com.bruce.main.LogCutter

DAEMON='-d'

CMD="$JAVA -cp $CLASSPATH:$APP_CLASSPATH:$APP_LIBS $APP_MAIN_CLASS -f $APP_CONFFILE"

if [ $# -eq 0 ]

then

$CMD

elif [ "$#" -eq 1 -a "$1" = "$DAEMON" ]

then

$CMD &

else

echo "Usage: $0 [ $DAEMON ]"

exit 1

fi
