I'm having this problem with load balancer. I already setup the load balancer and two servers behind it with this kind of topology
request -> DIRECTOR -- Server 1 \ Server 2
DIRECTOR's (RHEL 5) Virtual IP = 192.168.1.1 Server 1's (RHEL 4.4) Virtual IP = 192.168.1.2 Server 2's (CentOS 5.3) Virtual IP = 192.168.1.3
The problem is when I try to hit the 192.168.1.1, it sometimes give me a HTTP 200 and sometimes it will timed out. I hit it using lynx -dump. It should return "Hello world!" if success.
But if we hit it directly to 192.168.1.2:80 http://192.168.1.2:80 and 192.168.1.3:80 http://192.168.1.3:80, it will return HTTP 200 which means no error and no timeout. Since the Server 1 is the same as Server 2 in configuration, are there somethings I missed here?
Another information is that I set the director using round robin algorithm, so everytime a successful hit returned from server 1, the next one is surely heading to Server 2 right? Based on the Apache's access log, I also knew that the timed out occured when it is the Server 2's turn to handle the request.
Aside from the same httpd.conf and the same httpd version are there any things in the system level, kernel level that should be the same between those two servers?
Could you please post the heartbeat/ldirectord configs from /etc/ha.d/?
