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
 7、cp -r nutch-1.2 /home/ysc/apache-tomcat-7.0.29/webapps
 8、vi /home/ysc/apache-tomcat-7.0.29/webapps/nutch-1.2/WEB-INF/classes/nutch-site.xml
 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）

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

 在左部Package Explorer的 nutch1.5.1文件夹上单击右键 > Refresh
 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：

 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

 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

 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

 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

  </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
 11、web界面
  http://devcluster01:60010
  http://devcluster01:60030
 12、如运行nutch2.1则方法一：
  cp conf/hbase-site.xml /home/ysc/nutch-2.1/conf
  cd /home/ysc/nutch-2.1
  ant
  cd runtime/deploy
  unzip -d apache-nutch-2.1 apache-nutch-2.1.job
  rm  apache-nutch-2.1.job
  cd apache-nutch-2.1
  rm lib/hbase-0.90.4.jar
  cp /home/ysc/hbase-0.92.2/hbase-0.92.2.jar  lib
  zip -r ../apache-nutch-2.1.job ./*
  cd ..
  rm -r apache-nutch-2.1
 13、如运行nutch2.1则方法二：
  cp conf/hbase-site.xml /home/ysc/nutch-2.1/conf
  cd /home/ysc/nutch-2.1
  cp /home/ysc/hbase-0.92.2/hbase-0.92.2.jar  lib
  ant
  cd runtime/deploy
  zip -d apache-nutch-2.1.job lib/hbase-0.90.4.jar

 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：
