1、tools目錄文件結(jié)構(gòu)
[root@www tools]# tree tools/
tools/
├── bin
│ ├── del_history_files
│
└── etc
├── del_history_files.cfg
2 directories, 2 files
2、刪除歷史文件腳本 del_history_files
[root@www tools]# more tools/bin/del_history_files
#!/bin/sh
# 刪除指定目錄下，文件時(shí)間早于指定時(shí)間節(jié)點(diǎn)的文件，時(shí)間粒度：小時(shí)
# 配置文件格式 ： 需清理的目錄=小時(shí)數(shù)
#
#
# define restricted path
PATH="/bin:/usr/bin:/sbin:/usr/sbin"
# adirname - return absolute dirname of given file
adirname() { 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
fi
done
rm -rf ${MYLCK}
3、刪除歷史文件腳本的配置文件 del_history_files.cfg
[root@www tools]# more tools/etc/del_history_files.cfg
#需清理的目錄=小時(shí)數(shù)
/home/logs/nginx=720
/home/logs/varnish=720
4、crontab 執(zhí)行即可
[root@www tools]# more /etc/crontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/
#clear old logs
00 6 * * * root /home/tools/bin/del_history_files
