logrotate应用之按天切换jar包生成的日志

一、需求


 每晚11点59分切换日志，并生成日期后缀的日志


二、实施步骤


1、设置crontab 自动执行


[root@b32 jar_TongjiUdp_4.x]# crontab -l


## logrotate udplogs by days
59 23 * * * /usr/sbin/logrotate -f /opt/jar_TongjiUdp_4.x/rotateudplog -s /opt/jar_TongjiUdp_4.x/logrotate.status


2、rotateudplog文件内容


/opt/jar_TongjiUdp_4.x/logs/udplogs/*_log {


    rotate 7
    daily 
    copytruncate
    missingok
    dateext
    dateformat .%Y-%m-%d.log
    prerotate
    /opt/jar_TongjiUdp_4.x/shutdown.sh
    endscript  
    postrotate
    /opt/jar_TongjiUdp_4.x/startup.sh
    endscript
}


3、shutdown.sh 内容


#!/bin/sh
ps auxww | grep /opt/jar_TongjiUdp_4.x/udp_nvd.jar | grep -v grep | awk '{print $2}' | xargs -i kill -9 '{}'
exit 0


6、startup.sh 内容


#!/bin/sh
cd /opt/jar_TongjiUdp_4.x
nohup java -jar /opt/jar_TongjiUdp_4.x/udp_nvd.jar 40177 &
exit 0


三、必要条件




1、udp日志程序目录位置必须和上述配置和脚本相同


2、startup.sh和shutdown.sh必须要先手动执行通过


3、保证执行udp程序和执行crontab的用户是同一个
