Linux使用shell脚本定时删除历史日志文件

1、tools目录文件结构

[root@www tools]# tree tools/tools/├── bin│  ├── del_history_files│ └── etc  ├── del_history_files.cfg 2 directories, 2 files

2、删除历史文件脚本 del_history_files

[root@www tools]# more tools/bin/del_history_files#!/bin/sh # 删除指定目录下，文件时间早于指定时间节点的文件，时间粒度：小时# 配置文件格式 ： 需清理的目录=小时数### define restricted pathPATH="/bin:/usr/bin:/sbin:/usr/sbin" # adirname - return absolute dirname of given fileadirname() { odir=`pwd`; cd `dirname $1`; pwd; cd "${odir}"; }  # ---------# constants# ---------MYNAM=`basename "$0"`MYDIR=`adirname "$0"`MYCFG="${MYDIR}/../etc/${MYNAM}.cfg"MYTMP="${MYDIR}/../tmp"MYLCK="${MYTMP}/${MYNAM}.lock" # perform some locking (as good as it gets in a shell)[ -s "${MYLCK}" ] && kill -0 `cat "${MYLCK}"` 2>/dev/null &&    die "${MYNAM}: already running!"echo "$$" > "${MYLCK}" PATHS=(`cat ${MYCFG}`)for PP in ${PATHS[@]}do  APP_PATH=`echo ${PP} | awk -F'=' '{print $1}'`  N=`echo ${PP} | awk -F'=' '{print $2}'`    if [ -d ${APP_PATH} ] ; then    T=`/bin/date --date "${N} hours ago" "+%Y%m%d%H%M"`    TMP_FILE="/tmp/`echo ${PP} | md5sum | awk '{print $1}'`"    touch -t ${T} ${TMP_FILE}    find ${APP_PATH} ! -newer ${TMP_FILE} -type f -print0 | xargs -0 -n 100 rm -rf    find ${APP_PATH} -type d -empty -print0 | xargs -0 -n 100 rm -rf &> /dev/null    fidone rm -rf ${MYLCK}

3、删除历史文件脚本的配置文件 del_history_files.cfg

[root@www tools]# more tools/etc/del_history_files.cfg#需清理的目录=小时数/home/logs/nginx=720/home/logs/varnish=720

4、crontab 执行即可

[root@www tools]# more /etc/crontabSHELL=/bin/bashPATH=/sbin:/bin:/usr/sbin:/usr/binMAILTO=rootHOME=/#clear old logs00 6 * * * root /home/tools/bin/del_history_files
