YayCrawler 项目简介

YayCrawler爬虫技术交流 559745472 欢迎加群讨论,快速启动!!! 

项目目标 在力所能及的情况下,最大限度的提高 Web爬虫开发人员的生产力,爬虫框架里的一股清流

主要功能 基于WebMagic开发的完整的分布式爬虫框架,该框架特点如下: 1、完全分布式:由管理端(Admin)、调度端(Master)和多个Worker组成,各个组件通过Http协议通信。 2、完全配置化:通过Admin端的页面配置规则就可以爬取任何网站的数据,当然不同网站的难度不一样,会有不同的组件分别针对处理登录、验证码、封IP等问题。 3、可扩展的任务队列:任务队列由Redis实现,根据任务的状态有四种不同的任务队列:初始、执行中、成功、失败。您也可以扩展不同的任务调度算法,默认是公平调度。 4、可定义持久化方式:爬取结果中,属性数据默认持久化到MonogoDB,图片会被下载到文件服务器,当然您可以扩展更多的存储类型。 5、稳定和容错:任何一个爬虫任务都会重试和记录,只有任务真正成功了才会被移到成功队列,失败会有失败的原因描述。

技术选型 ● 核心框架:Webmagic Spring boot ● 任务调度:Spring + Quartz ● 持久层框架:Spring Jpa ● 数据库&连接池:Alibaba Druid MongoDB MySql ● 缓存框架:Redis Ehcache ● 日志管理:SLF4J、Log4j2 ● 前端框架: Bootstrap + Jquary

开发环境配置:

1.安装JDK8 2.安装mysql数据库,用作存储解析规则等数据,需要创建一个“yayCrawler”的数据库实例,并执行quartz相关的数据库脚本:quartz.sql(见发布包或源码)。 3.安装redis 4.安装mongoDB用于存放结果数据 5.安装ftp服务器软件ftpserver(可选,用于存放下载图片)

启动说明:

导入项目,maven install 安装 Admin,Worker,Master 模块。 然后生成的Jar拷贝到 crawler.worker / deploy 目录中,记住改配置文件里面的Redis,mysql mogodb 的IP ,点击start.bat启动。

(Linux & Windwos) java -jar worker.war --spring.config.location=worker_local.properties

关闭命令: (Windows) for /f "tokens=1-5 delims= " %%a in ('"netstat -ano|findstr "^:8086""') do taskkill /f /pid %%e

各组件通信说明:

一、Admin Admin层主要负责页面抽取规则配置,页面Site配置,资源管理和任务发布

二、Master 分布式爬虫的控制中心,接受Admin发布的任务,并分派任务给worker执行。 2.1、接收发布任务 2.2、接受Worker的注册 三、Worker 真正干事情的苦逼青年,接受Master分派的任务并执行,定时向Master汇报心跳

Docker镜像: 制作中。。。。。.。。

GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.
