需求：在生產(chǎn)上，要把服務(wù)器日志傳到日志備份服務(wù)器上 生產(chǎn)服務(wù)器上只保留7天前的日志 用shell腳本實(shí)現(xiàn)

備份腳本為

[root@xxx scripts]# cat back_log.sh

#!/bin/bash

#majihui

#backup prd3 block log to ip

#2019/2/25

/usr/bin/rsync -az /ivargo/log/* root@ip:/ivargo/prd3/$HOSTNAME/

然后做定時(shí)任務(wù)，每天凌晨1點(diǎn)傳到備份服務(wù)器上

刪除日志腳本，每天晚上當(dāng)時(shí)2點(diǎn)開(kāi)始刪除

[root@xxx scripts]# cat rm_7date_log.sh

#!/bin/bash

#majihui

#backup prd3 block log to ip

#2019/2/25

find /ivargo/log/ -type f -name "*log.2*" -mtime +6 |xargs rm -f

[root@xxx scripts]# crontab -l

#backup /ivargo/log to ip:/ivargo/prd3/

0 1 * * * /bin/sh /opt/scripts/back_log.sh >/dev/null 2>&1

#rm 7date log /ivargo/log

0 2 * * * /bin/sh /opt/scripts/rm_7date_log.sh >/dev/null 2>&1

提示：需要在備份服務(wù)器上提前創(chuàng)建好相應(yīng)的分組目錄，備份日志的時(shí)候，需要與備份主機(jī)建立好免密登陸。

擴(kuò)展：

上面的find命令還可以寫成

find /ivargo/log/ -type f -name "log.2" -mtime +6 -exec rm -f {} ;

例子

[root@NewCDH-0–144 log]# find /ivargo/log/ -type f -name "*log*24" -exec ls -l {} ;

-rw-r–r– 1 root root 0 Feb 25 13:05 /ivargo/log/NewCDH-0–144.log.2019-02-24

-rw-r–r– 1 root root 0 Feb 25 13:23 /ivargo/log/vpush/NewCDH-0–144.log.vpush.2019-02-24

[root@NewCDH-0–144 log]# find /ivargo/log/ -type f -name "*log*24" -exec rm -f {} ;

[root@NewCDH-0–144 log]# find /ivargo/log/ -type f -name "*log*24" -exec ls -l {} ;
