Hope some one out there can help me a clear up my understanding.
If I have 5 server on an upstream configuration list, to help load
balance
the load across the 5 servers. Once in a while I am seen “(110:
Connection timed out) while connecting to upstream”. Now what I am not
clear on is that message as a result of trying all the servers on the
upstream list or after failing on a single entry on the upstream list?
if
it is a single server then it should transfer the request to the next
server
on the list, right?

It’s about single server (and it should print server’s address in
the following text).

This depends on proxy_next_upstream directive, but usually the
answer is yes.
Thank you for your prompt reply. just one more … If I have 5
servers on
the upstream, use the IP_HASH, is the load distribution based on a round
robin when requests would go to the first on the list. then the second,
the third, … Or does NGIX create some kind of distribution array.
Thank you in advance.
