jira data center loading balancing with haproxy

Question

Hi I am trying to setup a JIRA cluster, I've gotten two nodes setup and they are behind an haproxy load balancer. When I try to login individually on each instance I can login using my admin credentials.

When I have added only one node to my haproxy config and I go to the load balancer url, I am able to login. However when I add both the nodes to the hapoxy config, I am not able to login using the balancer url. When I click submit on the login page after typing in my credentials, it doesn't show an error but just reloads the login page.

When I have both nodes in my haproxy config I can still login to each individual instance. Also the when i login to a specific instance and create a task/project etc.. it shows up in the other node. Where does the problem lie? I am thinking it has something to do with my haproxy configs but I am not sure.

Hi Oliver,

Yeah I ran across that as well, and it helped me get the cookies stuff working, but the problem was still there until I added this to the java startup variables on my JIRA nodes.

Hi,
please refer to this documentation :

https://confluence.atlassian.com/enterprise/jira-data-center-load-balancer-examples-781200827.html

I had the same problem on a testing environment. (I forgot to configure the session stickyness)

Greetings,
