nutch-2.1导入eclipse+mysql运行

初次接触nutch，记录下来

首先数据库 

CREATE DATABASE nutch DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_unicode_ci;

表

CREATE TABLE `webpage` (
  `id` varchar(767) NOT NULL,
  `headers` blob,
  `text` mediumtext,
  `status` int(11) default NULL,
  `markers` blob,
  `parseStatus` blob,
  `modifiedTime` bigint(20) default NULL,
  `score` float default NULL,
  `typ` varchar(32) default NULL,
  `baseUrl` varchar(767) default NULL,
  `content` longblob,
  `title` varchar(2048) default NULL,
  `reprUrl` varchar(767) default NULL,
  `fetchInterval` int(11) default NULL,
  `prevFetchTime` bigint(20) default NULL,

  `outlinks` mediumblob,
  `fetchTime` bigint(20) default NULL,

eclipse安装svn,ivy,ant

以上两个插件是nutch项目租使用的插件，自行安装。

nutch2.1的远程svn库文件地址

https://svn.apache.org/repos/asf/nutch/tags/release-2.1

check out检出项目

默认直接finish并创建java project项目

等待下载完成

下载完成后(注：这里的nutch2西面已做更改成nutch-2.1)

在project explorer下右击项目，选择properties。进入java build path
Add Folder > 导入选择，并把plugin下面的项目中的src/java和src/test都加入进去

src/bin
src/java
src/test
src/testresources

这一步也可以直接修改项目中的classpath文件，然后在直接刷新项目来自动添加，这样比较方便，但要注意是否有添加错误

刷新项目就跟上面一样了

接下order and export中要把conf提到最前面加载

这里处理玩之后接下来就是导包的过程

安装ivy的插件则能直接右击ivy.xml

直接finish。jar就会自动下载下来，需要注意，这里的ivy.xml有很多文件，只要有jar的都要add ivy library一次

这样去找会消耗点时间

当所有的ivy到导入后，最后总会有几个jar不存在的

(这里网上自行下载了，我这里自己另加入的包有)

另还有一个包hadoop-core的包需要修改，FileUtil.java

详情见http://yangshangchuan.iteye.com/blog/1839784

摘录下来(在运行时会提示错误)

错误信息：
Exception in thread "main" java.io.IOException:Failed to set permissions of path:	mphadoop-yscmapredstagingysc-2036315919.staging to 0700
 
官方BUG参考：
https://issues.apache.org/jira/browse/HADOOP-7682
 
解决方法：
1、下载并解压http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-1.1.2/hadoop-1.1.2.tar.gz
2、修改hadoop-1.1.2srccoreorgapachehadoopfsFileUtil.java，搜索 Failed to set permissions of path，找到689行，把throw new IOException改为LOG.warn
3、修改hadoop-1.1.2uild.xml，搜索autoreconf，移除匹配的6个executable="autoreconf"的exec配置
4、下载解压ant，将ant目录下的bin目录加入环境变量path
5、在Cygwin命令下行切换到hadoop-1.1.2目录，执行ant
6、用新生成的hadoop-1.1.2uildhadoop-core-1.1.3-SNAPSHOT.jar替换nutch的hadoop-core-1.0.3.jar
7、对于eclipse开发来说，替换C:Usersysc.ivy2cacheorg.apache.hadoophadoop-corejarshadoop-core-1.1.2.jar
 
附件中的JAR是对hadoop1.2.1修改后的JAR，可用于Nutch1.7，其他Nutch版本没测试过。

我在修改的时候直接下载这个然后替换ivy库中的hadoop-core包，名称一样；

下载http://pan.baidu.com/s/1i3FBLEP

接下里就是配置

在nutch2.1/conf下
Gora.properties
加入：

    gora.sqlstore.jdbc.driver=com.mysql.jdbc.Driver  
    gora.sqlstore.jdbc.url=jdbc:mysql://localhost:3306/nutch?createDatabaseIfNotExist=true  
    gora.sqlstore.jdbc.user=root  
    gora.sqlstore.jdbc.password=root

并注释掉其他的数据库链接。
在ivy/ivy.xml

解除mysql-connector的注释。

在/conf/nutch-site.xml.template的configuration中添加如下代码：

    <property>  
    <name>http.agent.name</name>  
    <value>Your Nutch Spider</value>  
    </property>

    <description>Value of the “Accept-Language” request header field.  
    This allows selecting non-English language as default one to retrieve.  
    It is a useful setting for search engines build for certain national group.  
    </description>  
    </property>

      and basic indexing and search plugins. In order to use HTTPS please enable   
      protocol-httpclient, but be aware of possible intermittent problems with the   
      underlying commons-httpclient library.  
      </description>  
    </property>  
      
    <property>  
    <name>storage.data.store.class</name>  
    <value>org.apache.gora.sql.store.SqlStore</value>  
    <description>The Gora DataStore class for storing and retrieving data.

    </description>  
    </property>  
      
    <property>  
      <name>plugin.folders</name>  
      <value>./src/plugin</value>  
      <description>Directories where nutch plugins are located.  Each  
      element may be a relative or absolute path.  If absolute, it is used

    </property>

在根目录下的build.xml中找到如下代码

    <target name="resolve-default" depends="clean-lib, init" description="--> resolve and retrieve dependencies with ivy">  
      <ivy:resolve file="${ivy.file}" conf="default" log="download-only" />  
      <ivy:retrieve pattern="${build.lib.dir}/[artifact]-[revision].[ext]" symlink="false" log="quiet" />  
      <antcall target="copy-libs" />  
     </target>

将原本的

    pattern="${build.lib.dir}/[artifact]-[revision].[ext]"

改为

pattern="${build.lib.dir}/[artifact]-[type]-[revision].[ext]"

用来避免ivy再次下载编译不通过的情况。原因：ivy会下载class的jar和source的jar，当时如果直接按照上面的pattern下载的话，两个文件是无法区分的。会出现相同的文件的错误。

完成如上信息之后，点击build.xml进行ant编译就会生成runtime目录。

在根目录下添加一个urls文件夹，放入seed.txt文件，其中加一个网站地址。如：http://nutch.apache.org/
打开

src/java下的crawl的package下的crawler，使用run configuration

第一页已经默认填写完毕


选择第二个arguments
放入：

urls -depth 3 -topN 5
-Xms64m -Xmx512m


最后就可以使用run进行爬取该网站的链接信息了。

执行完后打印

表中插入的数据

到直接基本算是在eclipse导入完成

接下自己慢慢学习了

 ---------------------------------------------------------------------------------

另一种简单方式

File > New > Project > SVN > 从SVN 检出项目
创建新的资源库位置 > 

URL:https://svn.apache.org/repos/asf/nutch/tags/release-1.7/

选中URL > Finish    弹出New Project向导,选择Java Project > Next,

输入Project name:nutch1.7 > Finishsd    

搭建环境

在左部Package Explorer的 nutch1.7文件夹上单击右键 >Build Path > Configure Build Path...
> 选中Source选项 > 选择src > Remove > Add Folder... > 选择src/bin, src/Java, src/test 和 src/testresources
切换到Libraries选项 >
Add Class Folder... > 选中nutch1.7/conf
Add Library... > IvyDE Managed Dependencies > Next >Main > Ivy File > Browse > ivy/ivy.xml > Finish
切换到Order and Export选项>选中conf > Top > OK

最后：在左部Package Explorer的 nutch1.7文件夹下的build.xml文件上单击右键 > Run As > Ant Build      (然后等待完成)
在左部Package Explorer的 nutch1.7文件夹上单击右键 > Refresh
在左部Package Explorer的 nutch1.7文件夹上单击右键 > Build Path > Configure Build Path... > 选中Libraries选项 > Add Class Folder... > 选中build >
等待完成

OK,整个工程导入完成，没有红叉
