HA Proxy won't load balance my web requests. What have I done wrong?
- by Josh Smeaton
I've finally got HA Proxy set up and running in a way I think I want. However, it is not load balancing the web requests it receives. All requests are currently being forwarded to the first server in the cluster. I'm going to paste my configuration below - if anyone can see where I may have gone wrong, I'd appreciate it.
This is my first stab at configuring web servers in a *nix environment.
First up, I have HA Proxy running on the same host as the first server in the apache cluster. We are moving these servers to virtual later on, and they will have different virtual hosts, but I wanted to get this running now.
Both web servers are receiving their health checks, and are reporting back correctly. The haproxy?stats page correctly reports servers that are up and down. I've tested this by altering the name of the file that is checked. I haven't put any load onto these servers yet. I've just opened up the URLs on several tabs (private browsing), and had several co-workers hit the URL too. All of the traffic goes to WEB1. Am I balancing incorrectly?
