Nutch2.1+mysql+solr3.6.1安装部署

1、mysql 数据库配置
    linux mysql安装步骤省略。
    创建数据库与表

    CREATE DATABASE nutch DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

    CREATE TABLE `webpage` (

`id` varchar(767) CHARACTER SET latin1 NOT NULL,
`headers` blob,
`text` mediumtext DEFAULT NULL,
`status` int(11) DEFAULT NULL,
`markers` blob,
`parseStatus` blob,
`modifiedTime` bigint(20) DEFAULT NULL,
`score` float DEFAULT NULL,
`typ` varchar(32) CHARACTER SET latin1 DEFAULT NULL,
`baseUrl` varchar(512) CHARACTER SET latin1 DEFAULT NULL,
`content` mediumblob,
`title` varchar(2048) DEFAULT NULL,
`reprUrl` varchar(512) CHARACTER SET latin1 DEFAULT NULL,
`fetchInterval` int(11) DEFAULT NULL,
`prevFetchTime` bigint(20) DEFAULT NULL,
`inlinks` mediumblob,
`prevSignature` blob,
`outlinks` mediumblob,
`fetchTime` bigint(20) DEFAULT NULL,
`retriesSinceFetch` int(11) DEFAULT NULL,
`protocolStatus` blob,
`signature` blob,
`metadata` blob,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2、安装nutch2.1
A、 nutch下载地址:http://apache.etoak.com/nutch/2.1/apache-nutch-2.1-src.zip

    下载完成后家压缩,
B、以下将nutch的根目录定位${APACHE_NUTCH_HOME}.
C、配置nutch对mysql的支持,修改${APACHE_NUTCH_HOME}/ivy/ivy.xml文件
    将这行的注释取消default”/>
    修改${APACHE_NUTCH_HOME}/conf/gora.properties文件,
        注释默认存储配置

        ###############################
# Default SqlStore properties #
###############################

#gora.sqlstore.jdbc.driver=org.hsqldb.jdbc.JDBCDriver
#gora.sqlstore.jdbc.url=jdbc:hsqldb:hsql://localhost/nutchtest
#gora.sqlstore.jdbc.user=sa
#gora.sqlstore.jdbc.password=
        取消以下代码注释,
###############################
# MySQL properties           
 ################################

gora.sqlstore.jdbc.driver=com.mysql.jdbc.Driver

gora.sqlstore.jdbc.url=jdbc:mysql://localhost:3306/nutch?createDatabaseIfNotExist=true

gora.sqlstore.jdbc.user=xxxxx(mysql用户名)

gora.sqlstore.jdbc.password=xxxxx(mysql密码)

D、修改${APACHE_NUTCH_HOME}/conf/nutch-site.xml 加入如下代码:

http.agent.name

Your Nutch Spider

http.accept.language

ja-jp, en-us,en-gb,en;q=0.7,*;q=0.3

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.

parser.character.encoding.default

utf-8

The character encoding to fall back to when no other information

is available

storage.data.store.class

org.apache.gora.sql.store.SqlStore

The Gora DataStore class for storing and retrieving data.

Currently the following stores are available: ….

E、使用ant编译   ${APACHE_NUTCH_HOME} 。


F、设置待抓取的网站
    cd ${APACHE_NUTCH_HOME}/runtime/local
    mkdir -p urls
    echo 'http://nutch.apache.org/' > urls/seed.txt
G、执行爬行操作: bin/nutch crawl urls -depth 3 -topN 5
    执行完在mysql中即可以查看到爬虫抓取的内容

3、安装solr,对nutch抓取的内容进行索引
    (注意:参考资料中推荐使用solr4.0版本,4.0的两个版本我都试了,没有成功,所以替换为3.6.1版本)
      solr下载地址:http://www.fayea.com/apache-mirror/lucene/solr/3.6.1/apache-solr-3.6.1.zip

    A、解压缩下载包,
    B、下载  http://nlp.solutions.asia/wp-content/uploads/2012/08/schema.xml替换${APACHE_SOLR_HOME}/example/solr/conf/schema.xml.
    C、启动solr 

        cd ${APACHE_SOLR_HOME}/example

    java -jar start.jar

     D 、在浏览器输入地址 http://localhost:8983/solr   测试是否启动成功。

        E、另起linux终端,输入如下命令,使solr对nutch抓取内容进行索引。

            cd ${APACHE_NUTCH_HOME}/runtime/local/

      bin/nutch solrindex http://127.0.0.1:8983/solr/ -reindex

4、测试
    在浏览器输入   http://localhost:8983/solr   ,看到如下界面:

在文本框中输入 content:nutch 点击查询,便可查处内容中包含nutch关键字的网页
