Installing OpenGrok on Windows

Installing OpenGrok on Windows

Steps for installing OpenGrok.

1. Download the OpenGrok binary from OpenGrok Binary.
2. Unzip the tar to a location say "G:\OpenGrok"
3. Download Ctags from Ctags Windows Binary.
4. Extract Ctags to a location say "G:\Ctags"
5. Download and install Tomcat.
6. OpenGrok needs the following to run
1. A configuration.xml that is generated using the command in step 8.
2. Location to the source being indexed. (SRC_ROOT)
3. Location to the "Ctag" generated grokData, again refer to step 8.  (DATA_ROOT)
7. Extract the "war" file in the "lib" folder in the extracted OpenGrok location. In this case  G:\opengrok-0.11.1\lib.
8. Edit the WEB-INF\web.xml file to include the information discussed above (step 6)

 <context-param>  
   <param-name>CONFIGURATION</param-name>  
   <param-value>G:\opengrok-0.11.1\configuration.xml</param-value>  
   <description>Full path to the configuration file where OpenGrok can read it's configuration</description>  
  </context-param>  
  -------Added the below------  
  <context-param>    
   <param-name>SRC_ROOT</param-name>  
   <param-value>G:\CodeSource</param-value>  
  </context-param>  
  <context-param>  
   <param-name>DATA_ROOT</param-name>  
   <param-value>G:\opengrok-0.11.1\grokdata</param-value>    
  </context-param>  

9. Copy the the extracted source.war with the modified web.xml to the tomcat webapps folder. 
10. Index the source and generate the configuration.xml file using the below command (G:\opengrok-0.11.1\lib has the jar file)

 java -jar opengrok.jar -W G:\opengrok-0.11.1\configuration.xml -c G:\ctags58\ctags.exe -P -S -v -s G:\CodeSource -d G:\opengrok-0.11.1\grokdata  

11. Launch Tomcat after the indexing in done. Open http://localhost:8080/source and wola you have a wicked fast source browser. 
12. Reindex if you need to add new projects/pick new source etc.
