一、nutch1.2
步骤和二大同小异，在步骤 5、配置构建路径 中需要多两个操作：在左部Package Explorer的 nutch1.2文件夹上单击右键 > Build Path > Configure Build Path... > 选中Source选项 > Default output folder:修改nutch1.2/bin为nutch1.2/_bin，在左部Package Explorer的
nutch1.2文件夹下的bin文件夹上单击右键 > Team > 还原
二中黄色背景部分是版本号的差异，红色部分是1.2版本没有的，绿色部分是不一样的地方，如下：
1、Add JARs... > nutch1.2 > lib ，选中所有的.jar文件 > OK
2、crawl-urlfilter.txt
3、将crawl -urlfilter.txt.template改名为crawl -urlfilter.txt
4、修改crawl-urlfilter.txt，将
# accept hosts in MY.DOMAIN.NAME
+^http://([a-z0-9]*\.)*MY.DOMAIN.NAME/
# skip everything else
-.
5、cd /home/ysc/workspace/nutch1.2
nutch1.2是一个完整的搜索引擎，nutch1.5.1只是一个爬虫。nutch1.2可以把索引提交给SOLR，也可以直接生成LUCENE索引，nutch1.5.1则只能把索引提交给SOLR：
1、cd /home/ysc
2、wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.29/bin/apache-tomcat-7.0.29.tar.gz
3、tar -xvf apache-tomcat-7.0.29.tar.gz
4、在左部Package Explorer的 nutch1.2文件夹下的build.xml文件上单击右键 > Run As > Ant Build... > 选中war target > Run
5、cd /home/ysc/workspace/nutch1.2/build
6、unzip nutch-1.2.war -d nutch-1.2

加入以下配置：
<property>
<name>searcher.dir</name>
<value>/home/ysc/workspace/nutch1.2/data</value>
<description>
Path to root of crawl. This directory is searched (in
order) for either the file search-servers.txt, containing a list of
distributed search servers, or the directory "index" containing
merged indexes, or the directory "segments" containing segment
indexes.
</description>
</property>
9、vi /home/ysc/apache-tomcat-7.0.29/conf/server.xml
将
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"/>
改为
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="utf-8"/>
10、cd /home/ysc/apache-tomcat-7.0.29/bin
11、./startup.sh
12、访问：http://localhost:8080/nutch-1.2/
关于nutch1.2更多的BUG修复及资料，请参看我在CSDN发布的资源：http://download.csdn.net/user/yangshangchuan
二、nutch1.5.1
1、下载并解压eclipse（集成开发环境）
下载地址：http://www.eclipse.org/downloads/，下载Eclipse IDE for Java EE Developers
2、安装Subclipse插件（SVN客户端）
插件地址：http://subclipse.tigris.org/update_1.8.x，
3、安装IvyDE插件（下载依赖Jar）
插件地址：http://www.apache.org/dist/ant/ivyde/updatesite/
4、签出代码
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-1.5.1/ > 选中URL > Finish
弹出New Project向导，选择Java Project > Next，输入Project name：nutch1.5.1 > Finish
5、配置构建路径
在左部Package Explorer的 nutch1.5.1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（对于插件，需要选中src/plugin目录下的每一个插件目录下的src/java ， src/test文件夹） > OK
切换到Libraries选项 >
Add Class Folder... > 选中nutch1.5.1/conf > OK
Add JARs... > 需要选中src/plugin目录下的每一个插件目录下的lib目录下的jar文件 > OK
Add Library... > IvyDE Managed Dependencies > Next > Main > Ivy File > Browse > ivy/ivy.xml > Finish

在左部Package Explorer的 nutch1.5.1文件夹上单击右键 > Build Path > Configure Build Path... > 选中Libraries选项 > Add Class Folder... > 选中build > OK
7、修改配置文件nutch-site.xml 和regex-urlfilter.txt
将nutch-site.xml.template改名为nutch-site.xml
将regex-urlfilter.txt.template改名为regex-urlfilter.txt
在左部Package Explorer的 nutch1.5.1文件夹上单击右键 > Refresh
将如下配置项加入文件nutch-site.xml：
<property>
<name>http.agent.name</name>
<value>nutch</value>
</property>
<property>
<name>http.content.limit</name>
<value>-1</value>
</property>
修改regex-urlfilter.txt，将
# accept anything else
+.
替换为：
+^http://([a-z0-9]*\.)*news.163.com/
-.
8、开发调试
在左部Package Explorer的 nutch1.5.1文件夹上单击右键 > New > Folder > Folder name: urls
在刚新建的urls目录下新建一个文本文件url，文本内容为：http://news.163.com
打开src/java下的org.apache.nutch.crawl.Crawl.java类，单击右键Run As > Run Configurations > Arguments > 在Program arguments输入框中输入: urls -dir data -depth 3 > Run
在需要调试的地方打上断点Debug As > Java Applicaton
9、查看结果
查看segments目录：
打开src/java下的org.apache.nutch.segment.SegmentReader.java类
单击右键Run As > Java Applicaton，控制台会输出该命令的使用方法
单击右键Run As > Run Configurations > Arguments > 在Program arguments输入框中输入: -dump data/segments/* data/segments/dump
用文本编辑器打开文件data/segments/dump/dump查看segments中存储的信息
查看crawldb目录：
打开src/java下的org.apache.nutch.crawl.CrawlDbReader.java类
单击右键Run As > Java Applicaton，控制台会输出该命令的使用方法
单击右键Run As > Run Configurations > Arguments > 在Program arguments输入框中输入: data/crawldb -stats
控制台会输出 crawldb统计信息
查看linkdb目录：
打开src/java下的org.apache.nutch.crawl.LinkDbReader.java类
单击右键Run As > Java Applicaton，控制台会输出该命令的使用方法
单击右键Run As > Run Configurations > Arguments > 在Program arguments输入框中输入: data/linkdb -dump data/linkdb_dump
用文本编辑器打开文件data/linkdb_dump/part-00000查看linkdb中存储的信息
10、全网分步骤抓取
在左部Package Explorer的 nutch1.5.1文件夹下的build.xml文件上单击右键 > Run As > Ant Build
cd /home/ysc/workspace/nutch1.5.1/runtime/local
#准备URL列表
wget http://rdf.dmoz.org/rdf/content.rdf.u8.gz
gunzip content.rdf.u8.gz
mkdir dmoz
bin/nutch org.apache.nutch.tools.DmozParser content.rdf.u8 -subset 5000 > dmoz/url
#注入URL
bin/nutch inject crawl/crawldb dmoz
#生成抓取列表
bin/nutch generate crawl/crawldb crawl/segments
#第一次抓取
s1=`ls -d crawl/segments/2* | tail -1`
echo $s1
#抓取网页
bin/nutch fetch $s1
#解析网页
bin/nutch parse $s1
#更新URL状态
bin/nutch updatedb crawl/crawldb $s1
#第二次抓取
bin/nutch generate crawl/crawldb crawl/segments -topN 1000
s2=`ls -d crawl/segments/2* | tail -1`
echo $s2
bin/nutch fetch $s2
bin/nutch parse $s2
bin/nutch updatedb crawl/crawldb $s2
#第三次抓取
bin/nutch generate crawl/crawldb crawl/segments -topN 1000
s3=`ls -d crawl/segments/2* | tail -1`
echo $s3
bin/nutch fetch $s3
bin/nutch parse $s3
bin/nutch updatedb crawl/crawldb $s3
#生成反向链接库
bin/nutch invertlinks crawl/linkdb -dir crawl/segments
11、索引和搜索
cd /home/ysc/
wget http://mirror.bjtu.edu.cn/apache/lucene/solr/3.6.1/apache-solr-3.6.1.tgz
tar -xvf apache-solr-3.6.1.tgz
cd apache-solr-3.6.1 /example
NUTCH_RUNTIME_HOME=/home/ysc/workspace/nutch1.5.1/runtime/local
APACHE_SOLR_HOME=/home/ysc/apache-solr-3.6.1
cp ${NUTCH_RUNTIME_HOME}/conf/schema.xml ${APACHE_SOLR_HOME}/example/solr/conf/
如果需要把网页内容存储到索引中，则修改 schema.xml文件中的
<field name="content" type="text" stored="false" indexed="true"/>
为
<field name="content" type="text" stored="true" indexed="true"/>
修改${APACHE_SOLR_HOME}/example/solr/conf/solrconfig.xml,将里面的<str name="df">text</str>都替换为<str name="df">content</str>
把${APACHE_SOLR_HOME}/example/solr/conf/schema.xml中的 <schema name="nutch" version="1.5.1">修改为<schema name="nutch" version="1.5">
#启动SOLR服务器
java -jar start.jar
http://127.0.0.1:8983/solr/admin/
http://127.0.0.1:8983/solr/admin/stats.jsp
cd /home/ysc/workspace/nutch1.5.1/runtime/local
#提交索引
bin/nutch solrindex http://127.0.0.1:8983/solr/ crawl/crawldb -linkdb crawl/linkdb crawl/segments/*
执行完整crawl:
bin/nutch crawl urls -dir data -depth 2 -topN 100 -solr http://127.0.0.1:8983/solr/
使用以下命令分页查看所有索引的文档：
http://127.0.0.1:8983/solr/select/?q=*%3A*&version=2.2&start=0&rows=10&indent=on
标题包含“网易”的文档：
http://127.0.0.1:8983/solr/select/?q=title%3A%E7%BD%91%E6%98%93&version=2.2&start=0&rows=10&indent=on
12、查看索引信息
cd /home/ysc/
wget http://luke.googlecode.com/files/lukeall-3.5.0.jar
java -jar lukeall-3.5.0.jar
Path: /home/ysc/apache-solr-3.6.1/example/solr/data
13、配置SOLR的中文分词
cd /home/ysc/
wget http://mmseg4j.googlecode.com/files/mmseg4j-1.8.5.zip
unzip mmseg4j-1.8.5.zip -d mmseg4j-1.8.5
APACHE_SOLR_HOME=/home/ysc/apache-solr-3.6.1
mkdir $APACHE_SOLR_HOME/example/solr/lib
mkdir $APACHE_SOLR_HOME/example/solr/dic
cp mmseg4j-1.8.5/mmseg4j-all-1.8.5.jar $APACHE_SOLR_HOME/example/solr/lib
cp mmseg4j-1.8.5/data/*.dic $APACHE_SOLR_HOME/example/solr/dic
将${APACHE_SOLR_HOME}/example/solr/conf/schema.xml文件中的
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
和
<tokenizer class="solr.StandardTokenizerFactory"/>
替换为
<tokenizer class="com.chenlb.mmseg4j.solr.MMSegTokenizerFactory" mode="complex" dicPath="/home/ysc/apache-solr-3.6.1/example/solr/dic"/>
#重新启动SOLR服务器
java -jar start.jar
#重建索引，演示在开发环境中如何操作
打开src/java下的org.apache.nutch.indexer.solr.SolrIndexer.java类
单击右键Run As > Java Applicaton，控制台会输出该命令的使用方法
单击右键Run As > Run Configurations > Arguments > 在Program arguments输入框中输入: http://127.0.0.1:8983/solr/ ; data/crawldb -linkdb data/linkdb
data/segments/*
使用luke重新打开索引就会发现分词起作用了
三、nutch2.0
nutch2.0和二中的nutch1.5.1的步骤相同，但在8、开发调试之前需要做以下配置：
在左部Package Explorer的 nutch2.0文件夹上单击右键 > New > Folder > Folder name: data并指定数据存储方式，选如下之一：
1、使用mysql作为数据存储
1）、在nutch2.0/conf/nutch-site.xml中加入如下配置：
<property>
<name>storage.data.store.class</name>
<value>org.apache.gora.sql.store.SqlStore</value>
</property>
2）、将nutch2.0/conf/gora.properties文件中的
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=
修改为
gora.sqlstore.jdbc.driver=com.mysql.jdbc.Driver
gora.sqlstore.jdbc.url=jdbc:mysql://127.0.0.1:3306/nutch2
gora.sqlstore.jdbc.user=root
gora.sqlstore.jdbc.password=ROOT
3）、打开nutch2.0/ivy/ivy.xml中的mysql-connector-java依赖
4）、sudo apt-get install mysql-server
2、使用hbase作为数据存储
1）、在nutch2.0/conf/nutch-site.xml中加入如下配置：
<property>
<name>storage.data.store.class</name>
<value>org.apache.gora.hbase.store.HBaseStore</value>
</property>
2）、打开nutch2.0/ivy/ivy.xml中的gora-hbase依赖
3）、cd /home/ysc
4）、wget http://mirror.bit.edu.cn/apache/hbase/hbase-0.90.5/hbase-0.90.5.tar.gz
5）、tar -xvf hbase-0.90.5.tar.gz
6）、vi hbase-0.90.5/conf/hbase-site.xml
加入以下配置：
<property>
<name>hbase.rootdir</name>
<value>file:///home/ysc/hbase-0.90.5-database</value>
</property>
7)、hbase-0.90.5/bin/start-hbase.sh
8)、将/home/ysc/hbase-0.90.5/hbase-0.90.5.jar加入开发环境eclipse的build path
四、配置SSH
三台机器 devcluster01， devcluster02， devcluster03，分别在每一台机器上面执行如下操作：
1、sudo vi /etc/hosts
加入以下配置：
192.168.1.1 devcluster01
192.168.1.2 devcluster02
192.168.1.3 devcluster03
2、安装SSH服务：
sudo apt-get install openssh-server
3、(有提示的时候回车键确认）
ssh-keygen -t rsa
该命令会在用户主目录下创建 .ssh 目录，并在其中创建两个文件：id_rsa 私钥文件。是基于 RSA 算法创建。该私钥文件要妥善保管，不要泄漏。id_rsa.pub 公钥文件。和 id_rsa 文件是一对儿，该文件作为公钥文件，可以公开。
4、cp .ssh/id_rsa.pub .ssh/authorized_keys
把 三台机器 devcluster01， devcluster02， devcluster03 的文件/home/ysc/.ssh/authorized_keys的内容复制出来合并成一个文件并替换每一台机器上的/home/ysc/.ssh/authorized_keys文件
在devcluster01上面执行时，以下两条命令的主机为02和03
在devcluster02上面执行时，以下两条命令的主机为01和03
在devcluster03上面执行时，以下两条命令的主机为01和02
5、ssh-copy-id -i .ssh/id_rsa.pub ysc@ devcluster02
6、ssh-copy-id -i .ssh/id_rsa.pub ysc@ devcluster03
以上两条命令实际上是将 .ssh/id_rsa.pub 公钥文件追加到远程主机 server 的 user 主目录下的 .ssh/authorized_keys 文件中。
五、安装Hadoop Cluster（伪分布式运行模式）并运行Nutch
步骤和四大同小异，只需要1台机器 devcluster01，所以黄色背景部分全部设置为devcluster01，不需要第11步
六、安装Hadoop Cluster（分布式运行模式）并运行Nutch
三台机器 devcluster01， devcluster02， devcluster03(vi /etc/hostname)
使用用户ysc登陆 devcluster01：
1、cd /home/ysc
2、wget http://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/hadoop-1.1.1/hadoop-1.1.1-bin.tar.gz
3、tar -xvf hadoop-1.1.1-bin.tar.gz
4、cd hadoop-1.1.1
5、vi conf/masters

<value>1</value>
</property>
<property>
<name>dfs.block.size</name>
<value>671088640</value>
<description>The default block size for new files.</description>
</property>
9、vi conf/mapred-site.xml
加入配置：
<property>
<name>mapred.job.tracker</name>
<value>devcluster01:9001</value>
<description>
The host and port that the MapReduce job tracker runs at. If
"local", then jobs are run in-process as a single map and
reduce task.

</property>
10、vi conf/hadoop-env.sh
追加：
export JAVA_HOME=/home/ysc/jdk1.7.0_05
export HADOOP_HEAPSIZE=2000
#替换掉默认的垃圾回收器，因为默认的垃圾回收器在多线程环境下会有更多的wait等待
export HADOOP_OPTS="-server -Xmn256m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70"
11、复制HADOOP文件
scp -r /home/ysc/hadoop-1.1.1 ysc@devcluster02:/home/ysc/hadoop-1.1.1
scp -r /home/ysc/hadoop-1.1.1 ysc@devcluster03:/home/ysc/hadoop-1.1.1
12、sudo vi /etc/profile
追加并重启系统：
export PATH=/home/ysc/hadoop-1.1.1/bin:$PATH
13、格式化名称节点并启动集群
hadoop namenode -format
start-all.sh
14、cd /home/ysc/workspace/nutch1.5.1/runtime/deploy
mkdir urls
echo http://news.163.com > urls/url
hadoop dfs -put urls urls
bin/nutch crawl urls -dir data -depth 2 -topN 100
15、访问 http://localhost:50030 可以查看 JobTracker 的运行状态。访问http://localhost:50060 可以查看
TaskTracker 的运行状态。访问http://localhost:50070 可以查看 NameNode 以及整个分布式文件系统的状态，浏览分布式文件系统中的文件以及 log 等
16、通过stop-all.sh停止集群
17、如果NameNode和SecondaryNameNode不在同一台机器上，则在SecondaryNameNode的conf/hdfs-site.xml文件中加入配置：
<property>
<name>dfs.http.address</name>
<value>namenode:50070</value>
</property>
七、配置Ganglia监控Hadoop集群和HBase集群
1、服务器端（安装到master devcluster01上）
1）、ssh devcluster01
2）、addgroup ganglia
adduser --ingroup ganglia ganglia
3）、sudo apt-get install ganglia-monitor ganglia-webfront gmetad
//补充：在Ubuntu10.04上，ganglia-webfront这个package名字叫ganglia-webfrontend
//如果install出错，则运行sudo apt-get update，如果update出错，则删除出错路径
4）、vi /etc/ganglia/gmond.conf
先找到setuid = yes,改成setuid =no;
在找到cluster块中的name，改成name =”hadoop-cluster”;
5）、sudo apt-get install rrdtool
6)、vi /etc/ganglia/gmetad.conf
在这个配置文件中增加一些datasource，即其他2个被监控的节点，增加以下内容：
data_source “hadoop-cluster” devcluster01:8649 devcluster02:8649 devcluster03:8649
gridname "Hadoop"
2、数据源端（安装到所有slaves上）
1)、ssh devcluster02
addgroup ganglia
adduser --ingroup ganglia ganglia
sudo apt-get install ganglia-monitor
2)、ssh devcluster03
addgroup ganglia
adduser --ingroup ganglia ganglia
sudo apt-get install ganglia-monitor
3）、ssh devcluster01
scp /etc/ganglia/gmond.conf devcluster02:/etc/ganglia/gmond.conf
scp /etc/ganglia/gmond.conf devcluster03:/etc/ganglia/gmond.conf
3、配置WEB
1）、ssh devcluster01
2）、sudo ln -s /usr/share/ganglia-webfrontend /var/www/ganglia
3）、vi /etc/apache2/apache2.conf
添加：
ServerName devcluster01
4、重启服务
1）、ssh devcluster02

2）、ssh devcluster01
sudo /etc/init.d/ganglia-monitor restart
sudo /etc/init.d/gmetad restart
sudo /etc/init.d/apache2 restart
5、访问页面
http:// devcluster01/ganglia
6、集成hadoop
1）、ssh devcluster01
2）、cd /home/ysc/hadoop-1.1.1
3）、vi conf/hadoop-metrics2.properties
# 大于0.20以后的版本用ganglia31 *.sink.ganglia.class=org.apache.hadoop.metrics2.sink.ganglia.GangliaSink31
*.sink.ganglia.period=10

十、配置zookeeper集群以运行hbase
1、ssh devcluster01
2、cd /home/ysc
3、wget http://mirror.bjtu.edu.cn/apache/zookeeper/stable/zookeeper-3.4.5.tar.gz
4、tar -zxvf zookeeper-3.4.5.tar.gz
5、cd zookeeper-3.4.5
6、cp conf/zoo_sample.cfg conf/zoo.cfg
7、vi conf/zoo.cfg
修改：dataDir=/home/ysc/zookeeper
添加：
server.1=devcluster01:2888:3888
server.2=devcluster02:2888:3888
server.3=devcluster03:2888:3888
maxClientCnxns=100
8、scp -r zookeeper-3.4.5 devcluster01:/home/ysc
scp -r zookeeper-3.4.5 devcluster02:/home/ysc
scp -r zookeeper-3.4.5 devcluster03:/home/ysc
9、分别在三台机器上面执行：
ssh devcluster01
mkdir /home/ysc/zookeeper（注：dataDir是zookeeper的数据目录，需要手动创建）
echo 1 > /home/ysc/zookeeper/myid
ssh devcluster02
mkdir /home/ysc/zookeeper
echo 2 > /home/ysc/zookeeper/myid
ssh devcluster03
mkdir /home/ysc/zookeeper
echo 3 > /home/ysc/zookeeper/myid
10、分别在三台机器上面执行：
cd /home/ysc/zookeeper-3.4.5
bin/zkServer.sh start
bin/zkCli.sh -server devcluster01:2181
bin/zkServer.sh status
十一、配置Hbase集群以运行nutch-2.1(Region Servers会因为内存的问题宕机)
1、nutch-2.1使用gora-0.2.1， gora-0.2.1使用hbase-0.90.4，hbase-0.90.4和hadoop-1.1.1不兼容，hbase-0.94.4和gora-0.2.1不兼容，hbase-0.92.2没问题。hbase存在系统时间同步的问题，并且误差要再30s以内。
sudo apt-get install ntp
sudo ntpdate -u 210.72.145.44
2、HBase是数据库，会在同一时间使用很多的文件句柄。大多数linux系统使用的默认值1024是不能满足的。还需要修改 hbase 用户的 nproc，在压力下，如果过低会造成 OutOfMemoryError异常。
vi /etc/security/limits.conf
添加：
ysc soft nproc 32000
ysc hard nproc 32000
ysc soft nofile 32768
ysc hard nofile 32768
vi /etc/pam.d/common-session
添加：
session required pam_limits.so
3、登陆master，下载并解压hbase
ssh devcluster01
cd /home/ysc
wget http://apache.etoak.com/hbase/hbase-0.92.2/hbase-0.92.2.tar.gz
tar -zxvf hbase-0.92.2.tar.gz
cd hbase-0.92.2
4、修改配置文件hbase-env.sh
vi conf/hbase-env.sh
追加：
export JAVA_HOME=/home/ysc/jdk1.7.0_05
export HBASE_MANAGES_ZK=false
export HBASE_HEAPSIZE=10000
#替换掉默认的垃圾回收器，因为默认的垃圾回收器在多线程环境下会有更多的wait等待
export HBASE_OPTS="-server -Xmn256m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70"
5、修改配置文件hbase-site.xml
vi conf/hbase-site.xml
<property>
<name>hbase.rootdir</name>
<value>hdfs://devcluster01:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>devcluster01,devcluster02,devcluster03</value>
</property>
<property>
<name>hfile.block.cache.size</name>
<value>0.25</value>
<description>
Percentage of maximum heap (-Xmx setting) to allocate to block cache
used by HFile/StoreFile. Default of 0.25 means allocate 25%.
Set to 0 to disable but it's not recommended.
</description>
</property>
<property>
<name>hbase.regionserver.global.memstore.upperLimit</name>
<value>0.4</value>
<description>Maximum size of all memstores in a region server before new
updates are blocked and flushes are forced. Defaults to 40% of heap
</description>
</property>
<property>
<name>hbase.regionserver.global.memstore.lowerLimit</name>
<value>0.35</value>
<description>When memstores are being forced to flush to make room in
memory, keep flushing until we hit this mark. Defaults to 35% of heap.
This value equal to hbase.regionserver.global.memstore.upperLimit causes
the minimum possible flushing to occur when updates are blocked due to
memstore limiting.
</description>
</property>
<property>
<name>hbase.hregion.majorcompaction</name>
<value>0</value>
<description>The time (in miliseconds) between 'major' compactions of all
HStoreFiles in a region. Default: 1 day.
Set to 0 to disable automated major compactions.
</description>
</property>
6、修改配置文件regionservers
vi conf/regionservers
devcluster01
devcluster02
devcluster03
7、因为HBase建立在Hadoop之上，Hadoop使用的hadoop*.jar和HBase使用的 必须 一致。所以要将 HBase lib 目录下的hadoop*.jar替换成Hadoop里面的那个，防止版本冲突。
cp /home/ysc/hadoop-1.1.1/hadoop-core-1.1.1.jar /home/ysc/hbase-0.92.2/lib
rm /home/ysc/hbase-0.92.2/lib/hadoop-core-1.0.3.jar
8、复制文件到regionservers
scp -r /home/ysc/hbase-0.92.2 devcluster01:/home/ysc
scp -r /home/ysc/hbase-0.92.2 devcluster02:/home/ysc
scp -r /home/ysc/hbase-0.92.2 devcluster03:/home/ysc
9、启动hadoop并创建目录
hadoop fs -mkdir /hbase
10、管理HBase集群:
启动初始 HBase 集群：
bin/start-hbase.sh
停止HBase 集群：
bin/stop-hbase.sh
启动额外备份主服务器，可以启动到 9 个备份服务器 (总数10 个)：
bin/local-master-backup.sh start 1
bin/local-master-backup.sh start 2 3
启动更多 regionservers, 支持到 99 个额外regionservers (总100个)：
bin/local-regionservers.sh start 1
bin/local-regionservers.sh start 2 3 4 5
停止备份主服务器:
cat /tmp/hbase-ysc-1-master.pid |xargs kill -9
停止单独 regionserver：
bin/local-regionservers.sh stop 1
使用HBase命令行模式:
bin/hbase shell
11、web界面

启用snappy压缩：
1、vi conf/gora-hbase-mapping.xml
在family上面添加属性：compression="SNAPPY"
2、mkdir /home/ysc/hbase-0.92.2/lib/native/Linux-amd64-64
3、cp /home/ysc/hadoop-1.1.1/lib/native/Linux-amd64-64/* /home/ysc/hbase-0.92.2/lib/native/Linux-amd64-64
4、vi /home/ysc/hbase-0.92.2/conf/hbase-site.xml
增加：
<property>
<name>hbase.regionserver.codecs</name>
<value>snappy</value>
</property>
十二、配置Accumulo集群以运行nutch-2.1(gora存在BUG)
1、wget http://apache.etoak.com/accumulo/1.4.2/accumulo-1.4.2-dist.tar.gz

rpc_address: 192.168.1.3
10、分别在3个节点上面运行
bin/cassandra
bin/cassandra -f 参数 -f 的作用是让 Cassandra 以前端程序方式运行，这样有利于调试和观察日志信息，而在实际生产环境中这个参数是不需要的（即 Cassandra 会以 daemon 方式运行）

mkdir dmoz
bin/nutch org.apache.nutch.tools.DmozParser content.rdf.u8 -subset 5000 > dmoz/url
#注入URL
bin/nutch inject crawl/crawldb dmoz
#生成抓取列表
bin/nutch generate crawl/crawldb crawl/segments
#第一次抓取
s1=`ls -d crawl/segments/2* | tail -1`
echo $s1
#抓取网页
bin/nutch fetch $s1
#解析网页
bin/nutch parse $s1
#更新URL状态
bin/nutch updatedb crawl/crawldb $s1
#第二次抓取
bin/nutch generate crawl/crawldb crawl/segments -topN 1000
s2=`ls -d crawl/segments/2* | tail -1`

11、索引和搜索
cd /home/ysc/
wget http://mirror.bjtu.edu.cn/apache/lucene/solr/3.6.1/apache-solr-3.6.1.tgz
tar -xvf apache-solr-3.6.1.tgz
cd apache-solr-3.6.1 /example
NUTCH_RUNTIME_HOME=/home/ysc/workspace/nutch1.5.1/runtime/local
APACHE_SOLR_HOME=/home/ysc/apache-solr-3.6.1
cp ${NUTCH_RUNTIME_HOME}/conf/schema.xml ${APACHE_SOLR_HOME}/example/solr/conf/
如果需要把网页内容存储到索引中，则修改 schema.xml文件中的
<field name="content" type="text" stored="false" indexed="true"/>
为
<field name="content" type="text" stored="true" indexed="true"/>
修改${APACHE_SOLR_HOME}/example/solr/conf/solrconfig.xml,将里面的<str name="df">text</str>都替换为<str name="df">content</str>
把${APACHE_SOLR_HOME}/example/solr/conf/schema.xml中的 <schema name="nutch" version="1.5.1">修改为<schema name="nutch" version="1.5">
#启动SOLR服务器
java -jar start.jar
http://127.0.0.1:8983/solr/admin/
http://127.0.0.1:8983/solr/admin/stats.jsp
cd /home/ysc/workspace/nutch1.5.1/runtime/local
#提交索引
bin/nutch solrindex http://127.0.0.1:8983/solr/ crawl/crawldb -linkdb crawl/linkdb crawl/segments/*
执行完整crawl:
bin/nutch crawl urls -dir data -depth 2 -topN 100 -solr http://127.0.0.1:8983/solr/
使用以下命令分页查看所有索引的文档：
http://127.0.0.1:8983/solr/select/?q=*%3A*&version=2.2&start=0&rows=10&indent=on
标题包含“网易”的文档：
http://127.0.0.1:8983/solr/select/?q=title%3A%E7%BD%91%E6%98%93&version=2.2&start=0&rows=10&indent=on
12、查看索引信息
cd /home/ysc/
wget http://luke.googlecode.com/files/lukeall-3.5.0.jar
java -jar lukeall-3.5.0.jar
Path: /home/ysc/apache-solr-3.6.1/example/solr/data
13、配置SOLR的中文分词
cd /home/ysc/
wget http://mmseg4j.googlecode.com/files/mmseg4j-1.8.5.zip
unzip mmseg4j-1.8.5.zip -d mmseg4j-1.8.5
APACHE_SOLR_HOME=/home/ysc/apache-solr-3.6.1
mkdir $APACHE_SOLR_HOME/example/solr/lib
mkdir $APACHE_SOLR_HOME/example/solr/dic
cp mmseg4j-1.8.5/mmseg4j-all-1.8.5.jar $APACHE_SOLR_HOME/example/solr/lib
cp mmseg4j-1.8.5/data/*.dic $APACHE_SOLR_HOME/example/solr/dic
将${APACHE_SOLR_HOME}/example/solr/conf/schema.xml文件中的
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
和
<tokenizer class="solr.StandardTokenizerFactory"/>
替换为
<tokenizer class="com.chenlb.mmseg4j.solr.MMSegTokenizerFactory" mode="complex" dicPath="/home/ysc/apache-solr-3.6.1/example/solr/dic"/>
#重新启动SOLR服务器
java -jar start.jar
#重建索引，演示在开发环境中如何操作
打开src/java下的org.apache.nutch.indexer.solr.SolrIndexer.java类
单击右键Run As > Java Applicaton，控制台会输出该命令的使用方法
单击右键Run As > Run Configurations > Arguments > 在Program arguments输入框中输入: http://127.0.0.1:8983/solr/ ; data/crawldb -linkdb data/linkdb
data/segments/*
使用luke重新打开索引就会发现分词起作用了
三、nutch2.0
nutch2.0和二中的nutch1.5.1的步骤相同，但在8、开发调试之前需要做以下配置：
在左部Package Explorer的 nutch2.0文件夹上单击右键 > New > Folder > Folder name: data并指定数据存储方式，选如下之一：
1、使用mysql作为数据存储
1）、在nutch2.0/conf/nutch-site.xml中加入如下配置：
<property>
<name>storage.data.store.class</name>
<value>org.apache.gora.sql.store.SqlStore</value>
</property>
2）、将nutch2.0/conf/gora.properties文件中的
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=
修改为
gora.sqlstore.jdbc.driver=com.mysql.jdbc.Driver
gora.sqlstore.jdbc.url=jdbc:mysql://127.0.0.1:3306/nutch2
gora.sqlstore.jdbc.user=root
gora.sqlstore.jdbc.password=ROOT
3）、打开nutch2.0/ivy/ivy.xml中的mysql-connector-java依赖
4）、sudo apt-get install mysql-server
2、使用hbase作为数据存储
1）、在nutch2.0/conf/nutch-site.xml中加入如下配置：
<property>
<name>storage.data.store.class</name>
<value>org.apache.gora.hbase.store.HBaseStore</value>
</property>
2）、打开nutch2.0/ivy/ivy.xml中的gora-hbase依赖
3）、cd /home/ysc
4）、wget http://mirror.bit.edu.cn/apache/hbase/hbase-0.90.5/hbase-0.90.5.tar.gz
5）、tar -xvf hbase-0.90.5.tar.gz
6）、vi hbase-0.90.5/conf/hbase-site.xml
加入以下配置：
<property>
<name>hbase.rootdir</name>
<value>file:///home/ysc/hbase-0.90.5-database</value>
</property>
7)、hbase-0.90.5/bin/start-hbase.sh
8)、将/home/ysc/hbase-0.90.5/hbase-0.90.5.jar加入开发环境eclipse的build path
四、配置SSH
三台机器 devcluster01， devcluster02， devcluster03，分别在每一台机器上面执行如下操作：
1、sudo vi /etc/hosts
加入以下配置：
192.168.1.1 devcluster01
192.168.1.2 devcluster02
192.168.1.3 devcluster03
2、安装SSH服务：
sudo apt-get install openssh-server
3、(有提示的时候回车键确认）
ssh-keygen -t rsa
该命令会在用户主目录下创建 .ssh 目录，并在其中创建两个文件：id_rsa 私钥文件。是基于 RSA 算法创建。该私钥文件要妥善保管，不要泄漏。id_rsa.pub 公钥文件。和 id_rsa 文件是一对儿，该文件作为公钥文件，可以公开。
4、cp .ssh/id_rsa.pub .ssh/authorized_keys
把 三台机器 devcluster01， devcluster02， devcluster03 的文件/home/ysc/.ssh/authorized_keys的内容复制出来合并成一个文件并替换每一台机器上的/home/ysc/.ssh/authorized_keys文件
在devcluster01上面执行时，以下两条命令的主机为02和03
在devcluster02上面执行时，以下两条命令的主机为01和03
在devcluster03上面执行时，以下两条命令的主机为01和02
5、ssh-copy-id -i .ssh/id_rsa.pub ysc@ devcluster02
6、ssh-copy-id -i .ssh/id_rsa.pub ysc@ devcluster03
以上两条命令实际上是将 .ssh/id_rsa.pub 公钥文件追加到远程主机 server 的 user 主目录下的 .ssh/authorized_keys 文件中。
五、安装Hadoop Cluster（伪分布式运行模式）并运行Nutch
步骤和四大同小异，只需要1台机器 devcluster01，所以黄色背景部分全部设置为devcluster01，不需要第11步
六、安装Hadoop Cluster（分布式运行模式）并运行Nutch
三台机器 devcluster01， devcluster02， devcluster03(vi /etc/hostname)
使用用户ysc登陆 devcluster01：

10、vi conf/hadoop-env.sh
追加：
export JAVA_HOME=/home/ysc/jdk1.7.0_05
export HADOOP_HEAPSIZE=2000
#替换掉默认的垃圾回收器，因为默认的垃圾回收器在多线程环境下会有更多的wait等待

10、cd hadoop-gpl-compression-0.1.0
11、cp lib/native/Linux-amd64-64/* /home/ysc/hadoop-1.1.1/lib/native/Linux-amd64-64/
12、cp hadoop-gpl-compression-0.1.0.jar /home/ysc/hadoop-1.1.1/lib/(这里hadoop集群的版本要和compression使用的版本一致)
13、scp -r /home/ysc/hadoop-1.1.1/lib devcluster02:/home/ysc/hadoop-1.1.1/
scp -r /home/ysc/hadoop-1.1.1/lib devcluster03:/home/ysc/hadoop-1.1.1/

<value>1440</value>
<description>Number of minutes between trash checkpoints.
If zero, the trash feature is disabled.
</description>
</property>

十、配置zookeeper集群以运行hbase
1、ssh devcluster01
2、cd /home/ysc
3、wget http://mirror.bjtu.edu.cn/apache/zookeeper/stable/zookeeper-3.4.5.tar.gz
4、tar -zxvf zookeeper-3.4.5.tar.gz
5、cd zookeeper-3.4.5
6、cp conf/zoo_sample.cfg conf/zoo.cfg
7、vi conf/zoo.cfg
修改：dataDir=/home/ysc/zookeeper
添加：
server.1=devcluster01:2888:3888
server.2=devcluster02:2888:3888
server.3=devcluster03:2888:3888
maxClientCnxns=100
8、scp -r zookeeper-3.4.5 devcluster01:/home/ysc
scp -r zookeeper-3.4.5 devcluster02:/home/ysc
scp -r zookeeper-3.4.5 devcluster03:/home/ysc
9、分别在三台机器上面执行：
ssh devcluster01
mkdir /home/ysc/zookeeper（注：dataDir是zookeeper的数据目录，需要手动创建）
echo 1 > /home/ysc/zookeeper/myid
ssh devcluster02
mkdir /home/ysc/zookeeper
echo 2 > /home/ysc/zookeeper/myid
ssh devcluster03
mkdir /home/ysc/zookeeper
echo 3 > /home/ysc/zookeeper/myid
10、分别在三台机器上面执行：
cd /home/ysc/zookeeper-3.4.5
bin/zkServer.sh start
bin/zkCli.sh -server devcluster01:2181
bin/zkServer.sh status
十一、配置Hbase集群以运行nutch-2.1(Region Servers会因为内存的问题宕机)
1、nutch-2.1使用gora-0.2.1， gora-0.2.1使用hbase-0.90.4，hbase-0.90.4和hadoop-1.1.1不兼容，hbase-0.94.4和gora-0.2.1不兼容，hbase-0.92.2没问题。hbase存在系统时间同步的问题，并且误差要再30s以内。
sudo apt-get install ntp
sudo ntpdate -u 210.72.145.44
2、HBase是数据库，会在同一时间使用很多的文件句柄。大多数linux系统使用的默认值1024是不能满足的。还需要修改 hbase 用户的 nproc，在压力下，如果过低会造成 OutOfMemoryError异常。
vi /etc/security/limits.conf
添加：
ysc soft nproc 32000
ysc hard nproc 32000
ysc soft nofile 32768
ysc hard nofile 32768
vi /etc/pam.d/common-session
添加：
session required pam_limits.so
3、登陆master，下载并解压hbase
ssh devcluster01
cd /home/ysc
wget http://apache.etoak.com/hbase/hbase-0.92.2/hbase-0.92.2.tar.gz
tar -zxvf hbase-0.92.2.tar.gz
cd hbase-0.92.2
4、修改配置文件hbase-env.sh
vi conf/hbase-env.sh
追加：
export JAVA_HOME=/home/ysc/jdk1.7.0_05
export HBASE_MANAGES_ZK=false
export HBASE_HEAPSIZE=10000
#替换掉默认的垃圾回收器，因为默认的垃圾回收器在多线程环境下会有更多的wait等待
export HBASE_OPTS="-server -Xmn256m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70"
5、修改配置文件hbase-site.xml
vi conf/hbase-site.xml
<property>
<name>hbase.rootdir</name>
<value>hdfs://devcluster01:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>devcluster01,devcluster02,devcluster03</value>
</property>
<property>
<name>hfile.block.cache.size</name>
<value>0.25</value>
<description>
Percentage of maximum heap (-Xmx setting) to allocate to block cache
used by HFile/StoreFile. Default of 0.25 means allocate 25%.
Set to 0 to disable but it's not recommended.
</description>
</property>
<property>
<name>hbase.regionserver.global.memstore.upperLimit</name>
<value>0.4</value>
<description>Maximum size of all memstores in a region server before new
updates are blocked and flushes are forced. Defaults to 40% of heap
</description>
</property>
<property>
<name>hbase.regionserver.global.memstore.lowerLimit</name>
<value>0.35</value>
<description>When memstores are being forced to flush to make room in
memory, keep flushing until we hit this mark. Defaults to 35% of heap.
This value equal to hbase.regionserver.global.memstore.upperLimit causes
the minimum possible flushing to occur when updates are blocked due to
memstore limiting.
</description>
</property>
<property>
<name>hbase.hregion.majorcompaction</name>
<value>0</value>
<description>The time (in miliseconds) between 'major' compactions of all
HStoreFiles in a region. Default: 1 day.
Set to 0 to disable automated major compactions.
</description>
</property>
6、修改配置文件regionservers
vi conf/regionservers
devcluster01
devcluster02
devcluster03
7、因为HBase建立在Hadoop之上，Hadoop使用的hadoop*.jar和HBase使用的 必须 一致。所以要将 HBase lib 目录下的hadoop*.jar替换成Hadoop里面的那个，防止版本冲突。
cp /home/ysc/hadoop-1.1.1/hadoop-core-1.1.1.jar /home/ysc/hbase-0.92.2/lib
rm /home/ysc/hbase-0.92.2/lib/hadoop-core-1.0.3.jar
8、复制文件到regionservers
scp -r /home/ysc/hbase-0.92.2 devcluster01:/home/ysc
scp -r /home/ysc/hbase-0.92.2 devcluster02:/home/ysc
scp -r /home/ysc/hbase-0.92.2 devcluster03:/home/ysc
9、启动hadoop并创建目录
hadoop fs -mkdir /hbase
10、管理HBase集群:
启动初始 HBase 集群：
bin/start-hbase.sh
停止HBase 集群：
bin/stop-hbase.sh
启动额外备份主服务器，可以启动到 9 个备份服务器 (总数10 个)：
bin/local-master-backup.sh start 1
bin/local-master-backup.sh start 2 3
启动更多 regionservers, 支持到 99 个额外regionservers (总100个)：
bin/local-regionservers.sh start 1
bin/local-regionservers.sh start 2 3 4 5
停止备份主服务器:
cat /tmp/hbase-ysc-1-master.pid |xargs kill -9
停止单独 regionserver：
bin/local-regionservers.sh stop 1
使用HBase命令行模式:
bin/hbase shell

rpc_address: 192.168.1.3
10、分别在3个节点上面运行
bin/cassandra
bin/cassandra -f 参数 -f 的作用是让 Cassandra 以前端程序方式运行，这样有利于调试和观察日志信息，而在实际生产环境中这个参数是不需要的（即 Cassandra 会以 daemon 方式运行）
