CoGe - Analytics

CoGe Analytics is a metrics and analytics engine for the CoGe platform written on Clojure's web framework Noir.

How To: Deploy on a Server via Apache Webserver

Prerequisites:

(You can install these CLI tools using your linux distributions preferred package manager)

• Apache2 - with plugins
  • libapache2-mod-proxy-html - For proxying the running port to the correct endpoints.
  • libxml2-dev
• Maven - For Clojure Dependencies
• Git - For cloning repos in from github
• Leingingen - Leiningen - Automate Clojure projects without setting your hair on fire.

Get Analytics Running:

Once you have all the prerequisites installed, you need to get the Greentea (Analytics) repo from Github. Run:

 `$ git clone https://github.com/LyonsLab/Greentea.git` 

Inside the cloned directory run:

 `$ lein run &`

it should pull in all the required dependencies* and start a Jetty servlet running on port 3456. Check localhost:3456 to verify that the analytics platform is running.

Configure Apache to Proxy the /analytics Endpoint

1. Now to setup apache to point localhost/analytics/ to port 3456
   1. Open '/etc/apache2/apache.conf' in your favorite editor and add these lines:

RewriteEngine On

ProxyPass /analytics/ http://localhost:3456/analytics/                       
ProxyPassReverse /analytics/ http://localhost:3456/analytics/                
                                                            
ProxyPass /analytics http://localhost:3456/analytics/                        
ProxyPassReverse /analytics http://localhost:3456/analytics/                 
                                                            
ProxyPass /greentea/ http://localhost:3456/greentea/                         
ProxyPassReverse /greentea/ http://localhost:3456/greentea/                  
                                                            
ProxyPass /greentea http://localhost:3456/greentea/                          
ProxyPassReverse /greentea http://localhost:3456/greentea/                   
</VirtualHost> 

*In the case of a common dependency issue with iplant-clojure-commons:

We need to point to the missing dependency manually: Run:

 `$ git clone https://github.com/iPlantCollaborativeOpenSource/iplant-clojure-commons.git`

In the iplant-clojure-commons directory, run:

 `$ lein uberjar` 

In lein 2.0 this will create a file at "<PATH>/iplant-clojure-commons/clojure-commons-1.3.3-SNAPSHOT-standalone.jar"

Replacing with appropriate <PATH>, run:

 `mvn install:install-file -DgroupId=org.iplantc -DartifactId=clojure-commons -Dversion=1.3.3-SNAPSHOT -Dpackaging=jar -Dfile=<PATH>/iplant-clojure-commons/clojure-commons-1.3.3-SNAPSHOT-standalone.jar`

Now try

 `$ lein clean` 

and then

 `$ lein run` 

The dependency issue should be resolved.
