Cherokee config file on shared filesystem?
Hope everyone had a good weekend!

Interested in hearing if anyone is running Cherokee on a shared
filesystem and sharing one Cherokee config file with multiple
machines.

What we are interested in doing is having one instance of Cherokee
Admin to edit our Cherokee config file.

Then we have multiple Cherokee dummy servers on different machines
that use the same config file.

This way we can edit one file and the config is changed for all our
Cherokee dummy servers. Simple use a distributed ssh command to
issue: killall -HUP cherokee and presto, all our dummies are running
the latest config file.

Right now, we have to manually load the admin up and change things on
each and every machine - which is time consuming and error prone.

Anyone doing something like this already? Is this an unsafe thing to
do, locking issues, etc.?

-Paul

It's specially interesting to notice that Jose speaks about a deployment in
the web farm of the ''Castilla la Mancha" government, one of the biggest
counties of Spain.

(Jose, please correct me if I'm wrong.)

Re: Cherokee config file on shared filesystem? [In reply to]
That's good news / endorsement of Cherokee if so :)

Excited to see large installations and those that are more complex
than one Cherokee instance. It shows that Cherokee is powering some
big sites and being used in ways that might not be just public
internet type applications.

Thanks for the info on shared directories. Quite exciting to think of
central logging from all the front ends (just 2 for us at the moment).

Next step for us will be a distributed self replicating filesystem to
do all of this on.

Hello,

We are currently testing, For now, we have tested with three Cherokee
virtual machines and 5 vservers.

We will put into production around 700 vservers websites with Cherokee,
within 2 months, with about 6-8 Xen virtual machines.

We want all virtual machines have all the 700 vservers configured to
perform a balancing vservers through a hardware balancer f5 type.

We're a little worried about the performance of the final solution. We
expect no problems. Alvaro, can we be reassured?, :-).

For example, about how to manage the cherokee-conf interface of many
vservers. I suggested that one could browse buttons to page back and
forward 10 by 10 vservers.

Greetings.

What is the reason you use Xen instead of native hardware? For
balancing it is only adding overhead.

We use Xen for Virtual Machines on Linux. Load balancing is through a
hardware balancer f5 type.

I suppose they are aiming for isolation. It makes pretty good sense in a

We want to use virtualization techniques, for to see the performance of
the architecture and final solution.
