Consult for load balance configuration with Nginx

[dujas]

Hi,

We have managed to deploy a Jira Service Management cluster with 2 nodes in data center version, along with a MS SQL database and a NFS shared FS.

We are trying to deploy a load balancer/reverse proxy with Nginx in front of the 2 nodes, the reverse proxy function works well if I only configure 1 node, but once I specified the upstream(jiracluster), the website will always be redirected back to the original one, e.g.: I access the website http://azailapp01:8080/, it loads the login page successfully, but once I finish typing into the username and password and click login, it redirects back to the login page. However, if I only set the proxy_pass with one specific jira node, it works fine.

Here is the config:

nginx:

user nginx;
worker_processes auto;

error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;


events {
    worker_connections 1024;
}


http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

    access_log /var/log/nginx/access.log main;

    sendfile on;
    #tcp_nopush on;

    keepalive_timeout 65;

    #gzip on;

    upstream jiracluster {
        server azailjir01:8080;
        server azailjir02:8080;
    }

    server {
        listen 8080;
        server_name azailapp01;

        access_log /var/log/nginx/jira.access.log;
        error_log /var/log/nginx/jira.error.log;

        location / {
           proxy_set_header X-Forwarded-Host $host;
           proxy_set_header X-Forwarded-Server $host;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_pass http://jiracluster;
        }
    }
}

server.xml(identical to another jira node):

<Connector port="8080" relaxedPathChars="[]|" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;"
maxThreads="150" minSpareThreads="25" connectionTimeout="20000" enableLookups="false"
maxHttpHeaderSize="8192" protocol="HTTP/1.1" useBodyEncodingForURI="true" redirectPort="8443"
acceptCount="100" disableUploadTimeout="true" bindOnInit="false" scheme="http"
proxyName="azailapp01" proxyPort="8080"/>

Issue got fixed after using HAproxy instead, referrence:

Well, though I changed the base URL to the nginx server's, still no luck.

Really need your help!
