我的博客已迁移到xdoujiang.com请去那边和我交流
1、日志结构
/opt/online/{123com,abccom}/log/online[1-9]/[a-z]

2、变量说明
#是否开启压缩功能(0:关闭,1:开启;若关闭压缩功能,则compressdayn无效)
needcompress=1
删除14天以前的日志
deldayn=14
前1天
lastdayn=1
服务类型
allsvrtype="online1 online2 online3"
压缩5天前的日志
compressdayn=5

3、计划任务使用方法:
将该脚本本身copy到/opt/online下;
crontab中配置成:
#30 0 * * * cd /opt/online && chmod +x cleanlog.sh && ./cleanlog.sh >/dev/null 2>&1

cat cleanlog.sh
#!/bin/bash
