日志备份和按时间删除日志脚本实现

备份脚本为

[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/

然后做定时任务，每天凌晨1点传到备份服务器上

删除日志脚本，每天晚上当时2点开始删除

[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：需要在备份服务器上提前创建好相应的分组目录，备份日志的时候，需要与备份主机建立好免密登陆。

扩展：

上面的find命令还可以写成

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 {} \;
