I had the following config where we are using AWS ELB for load balancing.
However, now we are keep getting backend test_cluster has no server
available!
Under this ELB two servers attached. Both instance are in healthy state.
Healthy state we are checking on port 80 and tomcat response sending on
port 8080
internal-testtomcatautoscale-1314784611.ap-southeast-1.elb.amazonaws.com
resolvers testresolver
nameserver dns1 169.254.169.253:53
resolve_retries 3
timeout retry 1s
hold valid 10s
backend test_cluster
mode http
option forwardfor
fullconn 10000
option httpchk /test-testalive
http-check expect string OK
option http-server-close
option abortonclose
balance roundrobin
server server1
internal-testtomcatautoscale-1314784611.ap-southeast-1.elb.amazonaws.com:8080
check resolvers testresolver
What could be the cause of this issue. How can i fix it.
