I'm running "HA-Proxy version 1.3.22" on Ubuntu Linux. I've got apache set up with two virtual hosts, and I want to use haproxy to round-robin between them. Ultimately, these virtual hosts will be on different machines, but for my testing environment, they're on the same box. I've got a config file I'm using for testing:
> global > maxconn 100 > > listen webfarm cluster6:23000 > mode http > option httpclose > balance roundrobin > cookie SERVERID insert indirect > timeout server 5s > timeout client 5s > timeout connect 5s > option httpchk GET /index.html HTTP/1.0 > server webA test1.cluster6.corp.amiestreet.com:80 cookie A check inter 2s > server webB test2.cluster6.corp.amiestreet.com:80 cookie B check inter 2s As soon as I start haproxy up, I get: > [WARNING] 228/171101 (20636) : Server webfarm/webA is DOWN. 1 active and 0 > backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue. > [WARNING] 228/171102 (20636) : Server webfarm/webB is DOWN. 0 active and 0 > backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue. > [ALERT] 228/171102 (20636) : proxy 'webfarm' has no server available! The problem seems to be that when it sends the HTTP requests to apache, it leaves out the Host: header. For example, strace shows that wget does: > write(3, "GET /index.html HTTP/1.0\r\nUser-Agent: Wget/1.12 > (linux-gnu)\r\nAccept: */*\r\nHost: > test1.cluster6.corp.amiestreet.com\r\nConnection: Keep-Alive\r\n\r\n", 142\ > ) = 142 but haproxy just does: > sendto(5, "GET /index.html HTTP/1.0\r\n\r\n", 28, MSG_DONTWAIT|MSG_NOSIGNAL, > NULL, 0) = 28 How do I get haproxy to work and play well with virtual hosts?
