HAProxy Load Balancer Configuration #199

Open parker20121 opened 8 years ago

parker20121 commented 8 years ago

I have bamboo/haproxy deployed on a set of mesos worker nodes using Marathon.

What I can figure out is how to put a haproxy server in front of them as a load balanacer.

The one I have will forward onto a haproxy on the work node, but I keep getting 400 (bad request) errors, and I'm not sure if there is something I'm missing on the haproxy load balancer configuration. Does anyone have a example haproxy configuration file used as a load balancer that I could compare mine too?

I am getting the below error repeatedly while connecting to the URL. I have bamboo/haproxy deployed on a set of mesos worker nodes using Marathon. Any thoughts? Lost connection to server at couchbase.xxx.com. Repeating in 1 seconds. 

#curl -IS couchbase.xxx.com
HTTP/1.0 503 Service Unavailable
Cache-Control: no-cache
Connection: close
Content-Type: text/html

<html><body><h1>503 Service Unavailable</h1>
No server is available to handle this request.
</body></html>

While accessing the URL in browser throws the error as below

503 Service Unavailable

No server is available to handle this request.

Can you run curl in verbose mode?

Did it forward to the right machine? Looks like it can find the right port.

@parker20121 Here is the verbose mode output. When we it the URL on browser it is forwarding to the correct haproxy. The webpage loads, and I am able to login but within couple of seconds it throws out "503 Service Unavailable" error.

I'm not a coachbase expert. After you login, is it forwarding onto another machine through haproxy?
