Subject RE: How to use the Load Balancer with openstack
Date Sun, 07 Jun 2015 10:18:07 GMT
In the /opt/stratos/apache-stratos-default/repository/conf/data-bridge/data-bridge-config.xml
of my stratos setup the 7611 and 7711 is used I don’t know from where it takes the 7811
port!!!!!

 

    <!-- Default configuration for thriftDataReceiver -->

    <thriftDataReceiver>

        <hostName>0.0.0.0</hostName>

        <port>7611</port>

        <securePort>7711</securePort>

    </thriftDataReceiver>

 

:/

Also from the base.pp  at the repository [1] there is no reference to 7811 and this is probably
the https port as I can see from the exception.

 

Cheers,

Hi,

 

I added manually to the lb vm, at stratos.sh in the command arguments and now i’m getting

Load balancer used thrift client to publish its statistics details periodically to the CEP.
Seems it can't connect to the port 7811. Are you running "ThriftDataReceiver" on 7811 port?

Subject: RE: How to use the Load Balancer with openstack

 

I had success with the nginx eventually. 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?

 

Regards,

Thanos

 

 

P.s the error I get is the following

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>
http://nginx.org/en/download.html. 

 

I’m getting this error now:

Seems load balancer can't find the program nginx. Did you download and extract Nginx binary
distribution and provide that nginx file path( -Dexecutable.file.path)  in nginx-extension.sh?

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

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

 

Athanasios Tsitsipas
