Hi I did that, right now. I installed the nginx to Ubuntu and provided the executable path(/usr/sbin/nginx).
If only download the distribution of nginx somehow I need to compile the code right?There is no executable file in it. I downloaded the distribution from this link: http://nginx.org/en/download.html. I’m getting this error now: [2015-06-06 13:59:04,464] INFO - [Nginx] Generating nginx configuration...

Stratos Load Balancer 2. Nginx (via extension) 3. HAproxy (via extension) First you could try to run either of these against your Stratos deployment and see whether they are working as expected (before trying the puppet module). Load balancer only requires ActiveMQ and CEP information (IP, port) to run. Do a complete build and find 1 in the following folder: https://github.com/apache/stratos/tree/master/products/load-balancer/modules/distribution Update loadbalancer.conf and thrift-client-config.xml with the above values and start the product.

More or less we can create many cartridges and use them with applications. But we need a load balancer now connected with a ghost application integrated with nodejs. What is the lb module in the puppet master modules and what is the haproxy. How we will subscribe the application we need to the load balancer and access the load balancer and redirect us to the multiple instances of the application above. Is there any guide we can use?
