How to use wildfly(undertow) as load balancer in domain mode without using Apache httpd?

[gipathak]

I want to use wildfly-12.0.0 as load balancer in domain mode , I could find the standalone mode configuration as below [https://www.youtube.com/watch?v=jhx7UaW8mCk] but I couldn't find any reference link for wildfly as load balancer in domain mode. I don't want to use apache httpd as a load balancer. I used this link [Wildfly load-balancing across multiple machines] also but it is telling only about standalone mode.If anyone can help me on domain mode with some sample example , it will be very useful.

I think what is shown in youtube video also works with a domain configuration. One server-group needs to get the load-balancer profile and load-balancer sockets in domain.xml. And the server in that group in host.xml needs to have auto-start=true so the loadbalancer starts. And for the profiles you need to do the same what is shown in the video. Config modcluster, security-key, ports, etc.

I'm trying to do the same thing but I'm stuck.

For now, i've successfuly created a cluster on three VMs with a master and two slaves in domain mode.

Everything works fine except for the load balancer.

I didn't found updated docs to get the job done, tried some stuff but nothing worked.

This is the topology:

(IPs, naming and all stuff are a mess, it's just a first approach)

Apps and persistence units are deployed and configured on master and replicated to slaves by the master, and context is accesible on all servers.

But if I try to get the context on port 80 (load balancer), all I got is a 404. Also, it doesn't show the "welcome to WildFly" startup page for no-context requests.

loadbalancer-host throws this warn on startup:

No routing provider found for default-server; using legacy provider based on static configuration

Here's the answer: mod cluster - WildFly 17 load balance with mod_cluster without apache in domain mode - Server Fault
