logrotate [OPTION...] <configfile>-d, --debug ：debug模式，測(cè)試配置文件是否有錯(cuò)誤。-f, --force ：強(qiáng)制轉(zhuǎn)儲(chǔ)文件。-m, --mail=command ：壓縮日志后，發(fā)送日志到指定郵箱。-s, --state=statefile ：使用指定的狀態(tài)文件。-v, --verbose ：顯示轉(zhuǎn)儲(chǔ)過程。

• 第一次執(zhí)行完rotate(輪轉(zhuǎn))之后，原本的messages會(huì)變成messages.1，而且會(huì)制造一個(gè)空的messages給系統(tǒng)來儲(chǔ)存日志；

• 第二次執(zhí)行之后，messages.1會(huì)變成messages.2，而messages會(huì)變成messages.1，又造成一個(gè)空的messages來儲(chǔ)存日志！

Logrotate是基于CRON來運(yùn)行的，其腳本是/etc/cron.daily/logrotate，實(shí)際運(yùn)行時(shí)，Logrotate會(huì)調(diào)用配置文件/etc/logrotate.conf。[root@test ~]# cat /etc/cron.daily/logrotate#!/bin/sh

Logrotate是基于CRON運(yùn)行的，所以這個(gè)時(shí)間是由CRON控制的，具體可以查詢CRON的配置文件/etc/anacrontab（老版本的文件是/etc/crontab）[root@test ~]# cat /etc/anacrontab# /etc/anacrontab: configuration file for anacron

第一個(gè)是Recurrence period第二個(gè)是延遲時(shí)間所以cron.daily會(huì)在3:22+(5,45)這個(gè)時(shí)間段執(zhí)行，/etc/cron.daily是個(gè)文件夾

--------------------------------------------------------------------------------------實(shí)例2:對(duì)nginx日志進(jìn)行切割[root@test-vm01 mnt]# vim log_rotate.py#!/usr/bin/env python
import datetime,os,sys,shutil
log_path = '/app/nginx/logs/'log_file = 'www_access.log'
yesterday = (datetime.datetime.now() - datetime.timedelta(days = 1))
try:    os.makedirs(log_path + yesterday.strftime('%Y') + os.sep + \                yesterday.strftime('%m'))
except OSError,e:    print    print e    sys.exit()

shutil.move(log_path + log_file,log_path \            + yesterday.strftime('%Y') + os.sep \            + yesterday.strftime('%m') + os.sep \            + log_file + '_' + yesterday.strftime('%Y%m%d') + '.log')

os.popen("sudo kill -USR1 `cat /app/nginx/logs/nginx.pid`")
--------------------------------------------------------------------------------------其他業(yè)務(wù)日志的切割腳本跟上面做法相同

[root@qd-vpc-op-consumer01 ~]# cat /app/script/log_rotate.sh#!/bin/sh
function rotate() {logs_path=$1
echo Rotating Log: $1cp ${logs_path} ${logs_path}.$(date -d "yesterday" +"%Y%m%d")> ${logs_path}    rm -f ${logs_path}.$(date -d "7 days ago" +"%Y%m%d")}
for i in $*do        rotate $idone
--------------------------------------------------------------------------------------------------------------每天定時(shí)切割日志的任務(wù)制定（比如對(duì)python的一個(gè)業(yè)務(wù)/data/log/xcspam/下的日志進(jìn)行切割，0K的日志不進(jìn)行切割）：[root@qd-vpc-op-consumer01 ~]# crontab -e#xcspam 日志切割30 0 * * * find /data/log/xcspam/ -size +0 -name '*.log' | xargs /app/script/log_rotate.sh
手動(dòng)執(zhí)行切割：[root@qd-vpc-op-consumer01 ~]# find /data/log/xcspam/ -size +0 -name '*.log' | xargs /app/script/log_rotate.sh
切割后的日志效果：[root@qd-vpc-op-consumer01 ~]# ls /data/log/xcspam/xcspam_error.log  xcspam_error.log-20170926
--------------------------------------------------------------------------------------------------------------比如對(duì)maridb日志進(jìn)行切割[root@qd-vpc-op-consumer01 ~]# crontab -e#xcspam 日志切割30 0 * * * find /var/log/mariadb/ -size +0 -name '*.log' | xargs /app/script/log_rotate.sh
[root@qd-vpc-op-consumer01 ~]# find /var/log/mariadb/ -size +0 -name '*.log' | xargs /app/script/log_rotate.sh[root@qd-vpc-op-consumer01 ~]# ll /var/log/mariadb/總用量 8-rw-r-----. 1 mysql mysql    0 9月  17 20:31 mariadb.log-rw-r-----. 1 root  root  4532 9月  17 20:31 mariadb.log.20170916--------------------------------------------------------------------------------------------------------------

日志壓縮腳本：[root@localhost ~]# ls /var/log/fss/nginx/nginx.20190506.log  nginx.20190507.log  nginx.20190508.log
[root@localhost ~]# cat /root/log_clean.sh#!/usr/bin/sh#根據(jù)系統(tǒng)/服務(wù)/日志保留天數(shù)三個(gè)參數(shù)壓縮日志#usage: sh clearlog.sh sysname appname keepdayssysName=$1appName=$2keepDay=$3logDir=/var/log/${sysName}/${appName}logFile=${appName}.*[0-9][0-9].logcd ${logDir}find ./ -name "${logFile}" -mtime -${keepDay} -exec gzip {} \;

[root@localhost ~]# sh /root/log_clean.sh fss nginx 3
[root@localhost ~]# ls /var/log/fss/nginx/nginx.20190506.log.gz  nginx.20190507.log.gz  nginx.20190508.log.gz
還可以針對(duì)日志保留策略，調(diào)整成日志清理腳本。

#!/bin/bash
yesterday=`date -d "-1 days" +'%Y%m%d'`cd `dirname $0`basedir=`pwd`logdir="${basedir}/bak"bindir="${basedir%/*}/sbin"mkdir -p ${logdir}
for log in `ls *.log 2>/dev/null`do    mv ${log} ${logdir}/${log}.${yesterday}.bak    # gzip ${logdir}/${log}.${yesterday}done
${bindir}/nginx -s reload
cd ${logdir}find . -type f -name "*.bak" -mtime +7 | xargs rm -f
