integrating haproxy with stratos
Hi experts,
I am new to stratos and exploring on how to integrate existing haproxy
cartridge with stratos.
I am referring
https://cwiki.apache.org/confluence/display/STRATOS/4.0.0+Configuring+HAProxy+Load+Balancer
After following steps mentioned in the link when I run
haproxy-extension.sh, I am getting following error messgae -
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in
[jar:file:/opt/apache-stratos-haproxy-extension-4.0.0-incubating/lib/slf4j-1.5.10.wso2v1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in
[jar:file:/opt/apache-stratos-haproxy-extension-4.0.0-incubating/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an
explanation.
[2014-06-08 09:57:39,480] WARN - [PropertiesFileInitialContextFactory]
Unable to load property file specified in
Provider_URL:repository/conf/jndi.properties
Due to:repository/conf/jndi.properties (No such file or directory)
This I am running in a VM which is expected to be a haproxy based load
balancerr.
Message is clear enough to indicate that repository/conf/jndi.properties
file is not found.
Question I have is, how do I get this repository directory? Is it going to
contain same 'conf' directory? Is it referring to directory on message
broker host or same host as haproxy?
<HAProxy_EXTENSION_HOME> is where I have extracted in
apache-stratos-load-balancer-4.0.0-incubating.zip and it doesn't have any
'repository' directory. Am I missing something important?
Thanks

Re: integrating haproxy with stratos
Posted by Dinesh Bandara <di...@wso2.com>.
Hi,
I have modified the HAProxy extension with followings
- HAProxy starts only once when it receives topology for the first time
- It will update member list when it received MemberActivatedEvent,
MemberSuspendedEvent, MemberTerminatedEvent,
ClusterRemovedEvent,ServiceRemovedEvent
- HAproxy can be used as default load balancer, earlier it was service
aware load balancer
Currently I'm working on HAProxy support to serve HTTPS requests.

Re: integrating haproxy with stratos
Posted by Parvez Shaikh <pa...@gmail.com>.

Re: integrating haproxy with stratos
Posted by Parvez Shaikh <pa...@gmail.com>.
Thanks Nirmal for follow up.
I traced the log after enabling DEBUG level. And it appears that topology
message keep on coming even if there is no topology change.
Due to this new topology event message, it appears that haproxy is being
respawned (previous instances still continue).
Is haproxy-extension.sh reading topology event in promiscuous mode i.e. not
really 'consuming' message (or not removing from queue after reading it)?
Is there a way to change this, where same topology event is not repeatedly
acknowledged and topology change leads to termination of previously started
haproxy before start of new one?
Let me know if I share logs.

Re: integrating haproxy with stratos
Posted by Parvez Shaikh <pa...@gmail.com>.
I figured out that we can provide bind-IP as a startup parameter in
haproxy-extension.sh (
http://mail-archives.apache.org/mod_mbox/stratos-dev/201402.mbox/%3CJIRA.12693370.1391613807947.42187.1391613969457@arcas%3E
)
However problem of repeated spawning of haproxy (even with default
configuration provided as a part of package) persists.
Thanks,
Parvez

Re: integrating haproxy with stratos
Posted by Parvez Shaikh <pa...@gmail.com>.
One more question, haproxy frontend always binds itself to 127.0.0.1:<proxy
port> for backend auto scaled VMs.
haproxy.cfg gets updated with following entries -
frontend xyz.xyz.domain-host-127.0.0.1-proxy-8280
* bind 127.0.0.1:8280 <http://127.0.0.1:8280>*
mode http
default_backend xyz.xyz.domain-host-127.0.0.1-proxy-8280-members
backend xyz.xyz.domain-host-127.0.0.1-proxy-8280-members
mode http
server xyz.xyz.domain85402fe9-733d-4d07-a15c-17bd0f72a672
172.16.2.21:22
server xyz.xyz.domain243f2caf-4860-4aba-80bf-96295c3010eb
172.16.2.22:22
server xyz.xyz.domain1dd22aac-2c27-433f-a99e-f257549d6fb2
172.16.2.25:22
server xyz.xyz.domain4edb342a-6ed7-44ef-858b-29edd31f68f9
172.16.2.24:22
server xyz.xyz.domaina9f27a71-064e-45f1-b92b-5d5728fb0b56
172.16.2.23:22
Is there a way we can change this to let it bind to 0.0.0.0 instead of
127.0.0.1 ? Like any cartridge property which can help in this?
Thanks,
Parvez

Any idea why is this happening? I replaced DEBUG everywhere there was INFO

none.

Re: integrating haproxy with stratos
Posted by Parvez Shaikh <pa...@gmail.com>.
it worked, there seems to be some parameters in our haproxy.cfg which is
upsetting this extension. On using default haproxy.cfg.template, it worked!
:-)
Can someone confirm, if following understanding that ports from port
mapping section of autoscaled cartridge are used by haproxy extension in
the following fashion -
"portMapping":[
{
"protocol":"http", // protocol
"port":"80", // port on autoscaled cartridge
"proxyPort":"8280" // port on haproxy / loadbalancer
cartridge
}
]
Thank you for all your quick support

Re: integrating haproxy with stratos
Posted by Parvez Shaikh <pa...@gmail.com>.
Thanks Nirmal,
it worked, however I am seeing an exception on the console as follows -
[2014-06-08 23:08:02,151] ERROR - [HAProxy] Could not start haproxy
[2014-06-08 23:08:02,152] ERROR - [LoadBalancerExtension] Could not start

root 31424 1 0 23:08 ? 00:00:00 /usr/sbin/haproxy -f
/tmp/haproxy.cfg -p /tmp/haproxy.pid
I want to know co-relation between cartridge agent and this
haproxy-extension script.
Should the VM that runs haproxy-extension script be subscribed through
stratos and have cartridge agent running? Should cartridge agent which runs
haproxy-extension indicate itself as load-balancer cartridge - in that case
how to indicate in cartridge definition to use this extension as load
balancer overriding default loadbalancer?
Right now load balancer VM (which runs haproxy) is not started by
subscribing cartridge through stratos console but by manually using IaaS
tools.
Any pointers/guidance would be useful.

Re: integrating haproxy with stratos
Posted by Parvez Shaikh <pa...@gmail.com>.
I downloaded activemq-5.9.jar from
http://activemq.apache.org/activemq-590-release.html and put that jar in
lib directory of HAPROXY_EXTENSION home.
I am seeing following message -
[2014-06-08 21:18:08,060] ERROR - [TopicSubscriber] Error while subscribing
to the topic: topology
javax.naming.NameNotFoundException: topicConnectionfactory
at
org.apache.activemq.jndi.ReadOnlyContext.lookup(ReadOnlyContext.java:235)

at
org.apache.stratos.messaging.broker.subscribe.TopicSubscriber.run(TopicSubscriber.java:116)
at java.lang.Thread.run(Thread.java:744)
Is there a way to move ahead?
Thanks,
P.S.
I did not put other dependencies like geronimo and hawtbuf, as did not get
any errors for these classes

Re: integrating haproxy with stratos
Posted by Nirmal Fernando <ni...@gmail.com>.
Sorry Parvez, we seems to lack documentation on this aspect.
You need to add following jars, to lib directory;
<!-- activemq client jars -->
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-j2ee-management_1.1_spec</artifactId>
<version>1.0.1</version>
</dependency>
<dependency>
<groupId>org.fusesource.hawtbuf</groupId>
<artifactId>hawtbuf</artifactId>
<version>1.9</version>
</dependency>
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-client</artifactId>
<version>5.9.1</version>

Re: integrating haproxy with stratos
Posted by Parvez Shaikh <pa...@gmail.com>.
I think we're using ActiveMQ as message broker, is there an easy or quick
way to confirm that?
Meanwhile the error changed -
javax.naming.NoInitialContextException: Cannot instantiate class:
org.apache.activemq.jndi.ActiveMQInitialContextFactory [Root exception is
java.lang.ClassNotFoundException:
org.apache.activemq.jndi.ActiveMQInitialContextFactory]
I just quickly tried to find the jar org.apache.activemq and couldn't find
it in "lib" directory that comes with HAPROXY-EXTENSION zip file.
Any pointers where to get this jar / class?

Re: integrating haproxy with stratos
Posted by Nirmal Fernando <ni...@gmail.com>.
Hi Parvez,
Seems like the extension code is broken. Are you using ActiveMQ as the
message broker? If so please replace your jndi.properties file with
following;
connectionfactoryName=TopicConnectionFactory
java.naming.provider.url=tcp://localhost:61616
java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory

Re: integrating haproxy with stratos
Posted by Imesh Gunaratne <im...@apache.org>.
Hi Parvez,
Welcome to Stratos, its really nice to hear that you are experimenting with
Stratos.
Regarding the issue you encountered, it seems like there is an invalid
entry in the jndi.properties file shipped with the HAProxy extension
package. Please open <HAPROXY_EXTENSION_HOME>/conf/jndi.properties file and
update java.naming.provider.url to following:
java.naming.provider.url=conf/jndi.properties
I will create a JIRA to fix this in the next release.
Thanks
