1. Create Index of source code

Cd/opt/opengrok

Mkdir data src

Cd src

Ln-s <your sourcecode> <project name>

Cd ../bin

OPENGROK_VERBOSE = true./OpenGrok index

Chown tomcat7: tomcat7 *-R

 

1. Create symbol link

To avoid OpenGrok complain about not found/var/opengrok/when doindex using root.

Mkdir-p/var/opengrok/etc/

Ln-s/opt/opengrok/etc/configuration. xml/var/opengrok/etc/configuration. xml

 

1. Update index automatically

Add execute/opt/opengrok/bin/OpenGrok to system crontab.

Sudo vim/etc/cron. daily/opengrok

#! /Bin/sh

/Opt/opengrok/bin/OpenGrokindex

Sudo chmod + x/etc/cron. daily/opengrok
