| 204 | | === 3.3. Modify the RSpec to automatically install and execute CCNX software === |
| 205 | | |
| 206 | | '''Background:''' For this experiment, we need to install the following software on the nodes: |
| 207 | | * The CCNX software (ccnx-0.6.2.tar.gz) |
| 208 | | * Scripts that set up the CCNX software (ccnx-setup.tar.gz) |
| 209 | | * Scripts used to pull atmospheric precipitation data using the CCNX protocol (ccnx-atmos.tar.gz) |
| 210 | | |
| 211 | | When the nodes start up, we need the following scripts to be executed: |
| 212 | | * Script that sets up the node (node-setup) |
| 213 | | * Script that sets up the ccnx protocol (ccnx-setup) |
| 214 | | * Script that setup up ccnx protocol routes (add-precip-routes) |
| 215 | | |
| 216 | | In the following steps we automate the installation and running of the software using install and execute scripts in the RSpec. |

| 274 | | You will be adding three install scripts. First, select "<tt>Add</tt>" under the <b>Install Scripts</b> sections as shown. In the box in the <b>URL</b> field enter (cut-and-paste): <br> |
