一、backup.sh
脚本
#/bin/bash
mysqldump --user=root --password='' --databases abc | gzip > /Back/www.dejaview.cn-`date +%Y%m%d%H%M`.sql.gz
tar czf abc.com-`date +%Y%m%d%H%M`.tar.gz /usr/local/nginx/html/abc.com
find /Back -name "*.gz" -mtime +7 -exec /bin/rm {} \;文件属性：组root[0]，拥有者root[0]，777
二、web目录
文件属性：组root[0]，拥有者nobody[99]
三、nginx，php
两个均是nobody下运行
四、问题
目前mysql可以定时导出来，不过web目录无法压缩，也无法删除7天以前的压缩包
五、错误日志
