Abstract

Cause the wealth of information available on the web keeps growing, we want to use web crawler to get them. But the traditional method has a fatal limit of its large infrastructure cost. To reduce it, we developed this method, unicrawl, which can show a performance improvement of 93.6% in terms of network bandwidth consumption, and a speedup factor of 1.75.

I. introduction

Nowadays, it’s common that to use parallel process on a large number of machines to achieve a reasonable collection time. While this method requires large computing infrastructures. Like Google and Bing, who rely on big data centers.

Motivation

Mobile devices have revolutionized how people share photos with each other on social networks with a single click of a button.

The content of the photos people shared to the internet are rarely analyzed by the websites before the photos are made available to view. After the photos are posted on the social network to the public to view, it is close to impossible to permanently delete the uploaded photos.

Photo leakage, regretion after posting and malicious posting happens from time to time.

前言：本教程包括了ubuntu上LAMP(Linux+Apache+Mysql+Php)环境的搭建以及zabbix安装。因为我们最终是要通过外部计算机访问我们的服务器的，所以我希望你可以先运行一下“ifconfig -a”语句来查看以下自己的IP地址，以方便之后测试服务器。文中将以“IPAddr”来代替你的IP地址，阅读时请注意。
