日志备份和按时间删除日志脚本实现

需求：在生产上，要把服务器日志传到日志备份服务器上 生产服务器上只保留7天前的日志 用shell脚本实现

备份脚本为

[[email?protected] scripts]# cat back_log.sh 
#!/bin/bash
#majihui
#backup prd3 block log to ip
#2019/2/25

/usr/bin/rsync -az /ivargo/log/* [email?protected]:/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

[[email?protected] 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

[[email?protected] 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

[[email?protected] 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
[[email?protected] log]# find /ivargo/log/ -type f -name "*log*24"  -exec rm -f {} ;      
[[email?protected] log]# find /ivargo/log/ -type f -name "*log*24"  -exec ls -l {} ;
