This post will show you how to run a workflow on Ranger  using Apache Airavata.
Applies to : Airavata 0.5-SNAPSHOT
Checkout and build Airavata1. Checkout the source from the svn trunk
svn co https://svn.apache.org/repos/asf/airavata/trunk2. Move to the root directory and build the trunk using maven.
eg: build with tests
mvn clean installeg: build skipping tests
mvn clean install -Dmaven.test.skip=true -o3. Unzip the apache-airavata-0.5-SNAPSHOT-bin.zip pack. The unzipped directory will be called AIRAVATA_HOME hereafter.
How to start the Airavata System Components with MySQLAiravata is running using Apache Derby as the backend database. You can use MySQL database instead of default derby database if you wish.
1. Create a new user called airavata with password airavata in running MySQL instance
mysql> CREATE USER 'airavata'@'localhost' IDENTIFIED BY 'airavata';2. Create a mysql database in your server with required name for user airavata (Assume name is:persistent_data)
mysql> CREATE DATABASE persistent_data; GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP ON persistent_data.* TO 'airavata'@'localhost' IDENTIFIED BY 'airavata';3. Copy mysql driver jar (-5.1.6.jar) to
4. Edit jdbc connection URLs at repository.properties file that resides in
registry.jdbc.url=jdbc:mysql://localhost:3306/persistent_data registry.jdbc.driver=com.mysql.jdbc.Driver5. In the next section we will try to run a workflow in Ranger . Configure the repository.properties file by modifying dummy values for following properties. The XSEDE cert files can be downloaded from .
trusted.cert.location=path to certificates for ranger myproxy.server=myproxy.teragrid.org myproxy.user=username myproxy.pass=password myproxy.life=36005. Go to
6. When starting XBaya, it should also point to the same database that we specified when starting Airavata server. In order to do that, copy the same repository.properties file that you have edited in the 2nd step, to
