Hi List,
I have two Squid servers in different subnets on different
geographical sites (LES link between the two) serving our users. I
would like to look into high availability/cluster services so that I
can move IP/Hostname around and take one out of commission – quite a
simple setup. I'd like some advice on it if possible. If all I want
to be able to do is move a hostname and IP to the other node thereby
taking one physical box out of commission to work on what does the
list recommend? I need to enable my colleagues (no knowledge of
Linux) to do this easily.
I'm thinking Red Hat Cluster Services but it seems a bit heavy for
this.. I'm just starting to read up on the High Availability project
but thought I'd get the question in..
Thanks
Nick
So whats wrong with updating the DNS then waiting for the old ones
traffic to stop before turning it off?
You can seed the new proxy by setting it with the original as parent.
Then spending a while leading up to the switch replicating a fetch of
all the old proxy access.log GET URLs. With the special header
"Cache-Control: only-if-cached" sent on the seeding requests.
