军歌LNMP1.0自带的日志分割，怎么日志这么大啊每个日志文件都有20多兆，
之前没有分割的只有几兆

#!/bin/bash
#function:cut nginx log files for lnmp v0.5 and v0.6
#author: http://lnmp.org

#set the path to nginx log files
log_files_path="/home/wwwlogs/"
log_files_dir=${log_files_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")
#set nginx log files you want to cut
log_files_name=(access wode021 51bieshu)
#set the path to nginx.
nginx_sbin="/usr/local/nginx/sbin/nginx"
#Set how long you want to save
save_days=30

#cut nginx log files
for((i=0;i<$log_files_num;i++));do
mv ${log_files_path}${log_files_name}.log ${log_files_dir}/${log_files_name}_$(date -d "yesterday" +"%Y%m%d").log
done

#delete 30 days ago nginx log files
find $log_files_path -mtime +$save_days -exec rm -rf {} \;

$nginx_sbin -s reload

脚本只是按原来的文件进行分割，不会增加日志的大小
