At the thrift-client-config.xml there is a configuration for the client. Which
ip and port should I include. By default in the zip file it has:
<!-- Apache thrift client configuration for publishing statistics to WSO2 CEP
-->
<thriftClientConfiguration>
<username>admin</username>
<password>admin</password>
<ip>localhost</ip>
<port>7711</port>
</thriftClientConfiguration>
At the nginx extention parameters it has also these arguments in the
nginx-extension.sh
-Dthrift.receiver.ip= <>
-Dthrift.receiver.port=7711
What should I do? And where I can specify these ports for thrift.
Also the template stratos.sh.erb is not used it seems that it takes the
parameters from the stratos.bat. Can you check the file at the end, there are
some syntax errors probably.

Thanos

Glad to hear that you have success with the nginx.
But now with the puppet module of stratos load balancer. I think there is a
problem:
In the stratos.sh on the spawned vm of load balancer under the folder /mnt/ ….
, where the zip file of lb is unzip it misses the
-Dthrift.client.config.file.path="$CARBON_HOME/repository/conf/thrift-client-config.xml"
\
A line that I get an error for! In the zip file at puppet master this line
exists, but not in the spawned vm. Can we get a workaround for this?
We need to add that property to the stratos.sh.erb of load balancer puppet
module. Now I have added that system property to the

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>

Subject: Re: How to use the Load Balancer with openstack
Hi Athanasios,
It's nice to hear that you are using the latest codebase, it has three load
balancing options:
1. 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.
Thanks

Hi there,
We are trying to install Stratos 4.1.0 and ok we got over some bugs in the
files. 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?
Many thanks in advance
