1. Crontab   命令直接添加

crontab –e

Add below lines to bottom of thefile

0 0-23/3 * * * zip/root2/opt/Avaya/ExperiencePortal/VPMS/SNMP/snmp-agent-daemon.$(date+\%d\%m\%y\%H\%M).zip/root2/opt/Avaya/ExperiencePortal/VPMS/SNMP/snmp-agent-daemon.txt

2.在/etc/crontab文件里添加

[sroot@AAEP7151 etc]# cat/etc/crontab

SHELL=/bin/bash

PATH=/sbin:/bin:/usr/sbin:/usr/bin

MAILTO=root

HOME=/

# For details see man 4 crontabs

# Example of job definition:

# .---------------- minute (0 -59)

# |  .------------- hour (0 - 23)

# |  | .---------- day of month (1 - 31)

# |  | |  .------- month (1 - 12) ORjan,feb,mar,apr ...

# |  | |  |  .---- day of week (0 - 6) (Sunday=0 or 7) ORsun,mon,tue,wed,thu,fri,sat

# |  | |  |  |

# *  * *  *  * user-name command to be executed

* * * * * root run-parts/etc/cron.hourly

3.利用logrotate机制

/etc/logrotate.conf的内容

在这里定义的优先级最低，如果在别处重新定义，讲覆盖

# rotate log files weekly

weekly

#hourly

# keep 4 weeks worth of backlogs

rotate 4

# create new (empty) log files afterrotating old ones

create

# use date as a suffix of the rotated file

dateext

# uncomment this if you want your log filescompressed

#compress

# RPM packages drop log rotationinformation into this directory

include /etc/logrotate.d   会去读取已经在/etc/logrotate.d   写好的脚本。

直接在etc/logrotate.conf里面添加要rotate的文件

/var/log/btmp {

   missingok

   monthly

   create 0600 root utmp

   rotate 1

}

/opt/Avaya/ExperiencePortal/VPMS/SNMP/fortest{

      daily

       copytruncate

        rotate 5

       notifempty

       missingok

}

即可

4.在/etc/logrotate.d里面添加新的脚本

[sroot@AAEP7151 etc]# cd /etc/logrotate.d

[sroot@AAEP7151 logrotate.d]# ll
