定期清理系统日志脚本

程序分为两部分：

/housekeep/scripts/housekeep_ux.cfg   （将需要清理的日志路径和相关配置写入此）

/housekeep/scripts/housekeep_ux.sh     （具体的清理执行脚本，设置完成后将housekeep_ux.sh加入cron）

要提前创建归档文件夹/housekeep/logs/archive；也可在housekeep_ux.sh中更改具体路径：ARCHIVE_DIR=/housekeep/logs/archive

/housekeep/scripts/housekeep_ux.cfg

#Log directory|Log file name|Log retention period|Log zip period|Archived
/housekeep/logs/archive|*|7|0|noarchive
/housekeep/logs|*.log|30|7|noarchive
/var/log|mail*|30|1|archive
/var/log|scpm|30|1|archive
/var/log|warn|30|1|archive
