shell_切割日志

可以修改的：
1.日志存放目录：logdir='/data/logs/'
2.每个类型日志保留个数：savefiles=30

#!/bin/bash
num=$(date -d"+1 day ago" +%Y%m%d%H%M%S)
logdir='/data/logs/'
savefiles=15

function cutfile(){
/bin/mv -f ${logdir}${1} ${logdir}${1%.log}_${num}.log
}

function delfile(){
nowfiles=$(ls -l ${logdir}${1%.log}_*.log | wc -l)
delfiles=$(expr ${nowfiles} - ${savefiles})
if [ ${delfiles} -gt 0 ];then
delflist=$(ls -lrth ${logdir}${1%.log}_*.log | head -${delfiles} | awk '{print $9}')
rm -rf ${delflist}
fi
}

logfiles=$(ls /data/logs | grep -v "[0-9]")
for i in ${logfiles}
do
cutfile ${i}
delfile ${i}
done

function clean(){
touch /data/logs/access_log.log
touch /data/logs/nginx_error.log
touch /data/logs/php-fpm-slow.log
touch /data/logs/php-fpm.log
#重新加载配置文件
/usr/local/nginx/sbin/nginx -s reload
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`
}
clean
