Balancing NGINX reverse proxy

[Alex Samad]

Hi

if I am reading this right, you currently have too much load on 1 nginx
server and you wish to releave this by adding another nginx server in front
of it ?

What I have is 2 nodes, but I use pacemaker instead of keepalive - i like
it as a better solution - but thats for another thread.

what you can do with pacemaker is have 1 ip address distributed between
multiple machines - up to 16 nodes I think from memory.

It uses linux iptables module for doing this. It is dependant on the source
ip's being distributed, if there are clamp together the hashing algo will
not make it any better.

How many requests are you getting to overload nginx - i thought it was able
to handle very large amounts ?

are your nodes big enough do you need more CPU's or memory or ??

Alex
