1. Install ctags

If you cannot run ctags command, install it.

apt-getinstall exuberant-ctags

 

1. Install Tomcat

sudoapt-get install tomcat7 tomcat7-docs tomcat7-examples tomcat7-admin

/etc/init.d/tomcat7 restart

sudo vim /etc/tomcat7/tomcat-users.xml   // add below change password before </tomcat-users>

<role rolename="manager-gui"/>

<role rolename="admin-gui"/>

<user username="admin" password="root123" roles="manager-gui,admin-gui"/>

sudo /etc/init.d/tomcat7 restart

Directories:

/etc/tomcat7 - Global configurations

　　 /usr/share/tomcat7/ - Program

　　/etc/tomcat7/Catalina/localhost/ - local Catalina configures

  　 /var/lib/tomcat7/ - tomcat home

　　/var/lib/tomcat7/webapps - applications

　　/var/lib/tomcat7/work - dynamic directory, such as dynamic compiled.jsp

 

 

Another way:

From http://tomcat.apache.org/ download Tomcat binary package. (apache-tomcat-7.0.42.tar.gz)

cd /opt

tar xvzf apache-tomcat-7.0.42.tar.gz

cd apache-tomcat-7.0.42/bin

./startup.sh     (use ./shutdown.sh to stoptomcat)

Visit: http://localhost:8080/

 

1. Install OpenGrok

From http://opengrok.github.io/OpenGrok/  download binaray file (opengrok-0.11.1.tar.gz).

cd /opt

tarxvzf opengrok-0.11.1.tar.gz

ln -s opengrok-0.11.1   opengrok

copy /opt/opengrok/lib/source.war to  /var/lib/tomcat6/webapps  or /opt/apache-tomcat-7.0.42/webapps/)

Visit http://localhost:8080/source/to confirm OpenGrok is installed OK.

 

1. Configure OpenGrok

add below line to /etc/profile.d/hansel.sh

exportOPENGROK_INSTANCE_BASE=/opt/opengrok

 

Modify /opt/apache-tomcat-7.0.42/webapps/source/WEB-INF/web.xml, change the path of opengrok.

<context-param> 

  <param-name>CONFIGURATION</param-name> 

   <param-value>/opt/opengrok/etc/configuration.xml</param-value> 

   <description>Full path to theconfiguration file where OpenGrok can read it'sconfiguration</description> 

 </context-param>

 

Setup password for using opengrok web page:

add role name to /etc/tomcat7/tomcat-users.xml

<rolerolename="opengrok"/>

<user username="opengrok" password="1234" roles="opengrok"/>

modify /var/lib/tomcat7/webapps/source/WEB-INF/web.xml, add below tothe bottom before "</web-app>":

  <security-constraint>

    <web-resource-collection>

      <web-resource-name>OpenGrokWeb</web-resource-name>

      <url-pattern>/*</url-pattern>

    </web-resource-collection>

    <auth-constraint>

      <role-name>opengrok</role-name>

    </auth-constraint>

  </security-constraint>

  <login-config>

   <auth-method>BASIC</auth-method>

   <realm-name>OpenGrok</realm-name>

  </login-config>

 

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
