Start Tomcat service, open http://localhost:8080/manager/html

 

Move to “WAR file to deploy”, upload file: C:/dev/search/netch/nutch-0.9/nutch-0.9.war.

 

Close Tomcat service, change directory name “ROOT” in “C:/Program Files/Apache Software Foundation/Tomcat 6.0/webapps” to “ ROOT-backup”, change directory name “nutch-0.9” in “C:/Program Files/Apache Software Foundation/Tomcat 6.0/webapps” to “ ROOT”.( OR do nothing)

 

5 Configure and run nutch

Create directory “urls” in “C:/dev/search/netch/nutch-0.9”.

Create a file “testurlfile” in directory “urls”.

Add line: “http://www.bokee.com “ to  file “testurlfile”.

Find file “C:/dev/search/netch/nutch-0.9/conf/ crawl-urlfilter.txt”, replace “MY.DOMAIN.NAME” with “bokee.com”

 

 

Find file “C:/dev/search/netch/nutch-0.9/conf/ nutch-site.xml”, edit it to this:

 

 

 

  http.agent.name

  nutch

  HTTP 'User-Agent' request header. MUST NOT be empty -

  please set this to a single word uniquely related to your organization.

 

  NOTE: You should also check other related properties:

 

       http.robots.agents

       http.agent.description

       http.agent.url

       http.agent.email

       http.agent.version

 

  and set their values appropriately.

  liming agent.description

  Further description of our bot- this text is used in

  the User-Agent header.  It appears in parenthesis after the agent name.

 

 

  http.agent.url

 

  A URL to advertise in the User-Agent header.  This will

   appear in parenthesis after the agent name. Custom dictates that this

   should be a URL of a page explaining the purpose and behavior of this

   crawler.

 

 

  http.agent.email

  agent.email

  An email address to advertise in the HTTP 'From' request

header and User-Agent header. A good practice is to mangle this
