Abstract

The invention discloses a web crawler system and a web crawler multitask executing and scheduling method. The method includes: A, according to different content and website characteristics, subjecting crawled content to fine-grained segmentation, respectively creating crawler parsing template files, and arranging web crawlers to be respectively combined the crawler parsing template files to form acquisition modules used for executing crawling tasks; B, respectively deploying the web crawlers on multiple node servers, wherein each node server is provided with a scheduler used for scheduling the crawling tasks; C, invoking the associated acquisition modules to execute the crawling tasks to perform data acquisition through the schedulers according to a predefined scheduling strategy. The crawled content is subjected to fine-grained segmentation so as to realize high-concurrency execution of the tasks, a load balancing strategy is adopted, server resources are fully utilized, and crawling efficiency is improved obviously; besides, the problem of low system reliability caused by single-machine fault is solved, and high-reliability running of a system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of search engines, in particular to a web crawler system and a web crawler multi-task execution and scheduling method. Background technique [0002] With the explosive growth of Internet information, the traditional way of collecting data by web crawlers has gradually shown its disadvantages. Traditional web crawlers do not have fine-grained segmentation of tasks when collecting data, which takes a long time. Due to the limitations of server CPU, memory and network bandwidth, data crawling efficiency is relatively low, and single point failures are prone to occur. [0003] Therefore, the existing technology still needs to be improved and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a web crawler system and a web crawler multi-task execution and scheduling method, aiming at solving the problems...
