[SOLVED] How to Install ODK Aggregate in Ubuntu Server?

Dhanyamol.kv | | 2 min read

Open Data Kit (ODK) is an open-source suite of tools that helps to Build survey form, Collect data on a mobile device and send it to a server and Aggregate the collected data on a server and extract it in useful formats. ODK Aggregate can be deployed on Google's App Engine, by creating google account. ODK Aggregate can also be deployed locally on a Tomcat server backed with a MySQL or PostgreSQL database server.

Steps to setup ODK Aggregate in our server,

  1. Install Java 
    $ sudo apt-get install java7-jdk
    To check whether java installed properly , use 
    java -version
  2. Then open ~/.bashrc with your editor and add: export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64 at the bottom of that file.
  3. Install tomcat7 
    sudo apt-get install tomcat7
  4. Edit context.xml (under Tomcat 7's conf directory - /var/lib/tomcat7/conf) to have the attribute 'useHttpOnly' set to false.
  5. Download the correct version of ODK Aggregator and then install it. 
    sudo wget  https://s3.amazonaws.com/opendatakit.downloads/ODK\ Aggregate\ v1.4.7\ linux-x64-installer.run (For 64 bit)
$ sudo chmod +x ODK\ Aggregate\ v1.4.7\ linux-x64-installer.run
$ ./ODK\ Aggregate\ v1.4.7\ linux-x64-installer.run
    The installer does not install anything, but will guide you through configuring ODK Aggregate for Tomcat and MySQL/PostgreSQL. Set Parent Directory to your path. - Platform: MySQL - No SSL (for now) - HTTP Port: 8080 - IP Address or DNS: localhost
  6. Download and Install Latest MySQL Connector (http://dev.mysql.com/downloads/connector/j/5.1.html) 
    $ sudo wget http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.36.tar.gz
$ sudo tar -xzf mysql-connector-java-5.1.36.tar.gz
$ sudo cp mysql-connector-java-5.1.36/mysql-connector-java-5.1.36-bin.jar /usr/share/tomcat7/lib/
    - Database Port: 3306 - Database Host: 127.0.0.1 - Continue...
  7. The installer will produce a WAR file (web archive) containing the configured ODK Aggregate server, a create_db_and_user.sql script for creating the database and user and a Readme.html file with instructions on how to complete the installation.
  8. Set up database (run script)
  9. Place war file on web server 
    $ cd ~/ODK Aggregate
$ sudo cp ODK\ Aggregate/ODKAggregate.war /var/lib/tomcat7/webapps/
    - the war file should automatically unpack and create an ODKAggregate directory.
  10. Restart Apache sudo service tomcat7 restart
  11. Visit http://domain_name:8080/ODKAggregate/
    NOTE: It may take a few moments for the Apache Tomcat server to detect the ODKAggregate.war. if you get a 404 error, wait a few moments then refresh your browser. If you want ODKAggregate to be reached at just http://domain_name:8080/, you can rename it to ROOT.war before copying it to the /webapps directory.
