本节我将向大家介绍如何运行与调试YayCrawler。该框架是采用SpringBoot开发的，所以可以通过java –jar xxxx.jar的方式运行，也可以部署在tomcat等容器中运行。

首先让我们介绍一下运行环境：

1、jdk8

2、安装mysql数据库，用作存储解析规则等数据

3、安装redis，用作任务队列

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）

一、运行发布包

首先从https://github.com/liushuishang/YayCrawler.Release.git获取release包，目录如下：

每个文件夹里面的文件结构是一样的，以admin文件夹为例

casperjs和phantomjs两个文件夹是为了执行某些特殊操作准备的，这里先不用理会。xxx_local.properties是一个服务配置文件，里面有配置端口、数据库连接等参数，可以按照实际参数来调整；quartz.sql是运行quartz框架需要的数据库表脚本，方在这里是为了方便；start.bat和start.vbs都是启动脚本，双击就可以启动admin端，start.bat会在控制台输出日志内容，start.vbs是在后台执行，不会弹出控制台，启动后会在该文件夹产生一个“catalina.base_IS_UNDEFINED”的文件夹，里面存放的是输出日志；双击stop.bat就可以停止admin端程序。我们双击start.bat来启动admin端程序：

可以看到admin端已经成功启动，浏览器http://localhost:8069/admin/即可访问管理界面：

Master与Worker的启动与上面Admin端一致，只是没有web界面，这里不再赘述。

二、源码的运行与调试

首先从https://github.com/liushuishang/YayCrawler.git拉取源码，然后用Intellij Idea打开（Eclipse也可以），可以看到如下的目录解构：

yaycrawler-admin:Web管理控制台，用户可以这里配置解析规则、测试规则、查看任务队列情况和发布任务等。

yaycralwer-master：管理任务队列和任务调度，与admin和worker互相通信。

yaycralwer-worker：爬虫任务的工作端，定时向master发送心跳，接收并执行任务，负责数据的持久化。

yaycralwer-spider：与WebMagic结合，负责下载页面、解析页面、定义爬虫任务的处理流程和接口。

yaycrawler-common:公用的实体模型和工具包。

yaycralwer-monitor：提供反监控的工具包，比如验证码刷新、自动登陆等

yaycralwer-proxy：工具包，用于从网上搜索可用的ip代理

yaycrawler-cache:为框架提供数据缓存功能的组件。

yaycrawler-quartz：通用的定时任务调度组件，可以通过配置定时调度不同的任务。可以用来做定时爬虫任务。

yaycrawler-dao:提供与mysql数据库交互的功能。

yaycrawler-ftpserver:ftpserver客户端工具包。

我们分别为admin、master和worker配置三个TomcatServer，各占用的http端口如下图所示。

然后分别修改各自工程下的src/main/resources/application.properties文件，如(请注意红色的部分配置)
