[lvs-users] remomendation/advice.

Hi guys I am new to the list and to LVS..
I have a project for a couple customers to build a
load balancer for web/mysql services, and this needs to be up
24/7 of course! hehe
I always rather use free software than to buy a proprietary product that
does
the same, so I want to give LVS a try on my staging/testing network.
what do you guys recommend for me to use under this circumstances?
I will have 2-3 apache with at least 2 mysql doing replication in the
back of the webservers..
also what solution is there so LVS is also redundant so there is no
single point of failure.

Thanks so much and I hope to be part of the community soon.

all of this is adressed in the HOWTO. To save us reading it
to you, how about you read the HOWTO and set up a test LVS
and then get mysqld/httpd working

Because the "howto" gives like 20 solution and 20 third party
applications that seems to do exactly the
same thing.. but I need experience talk, not a howto if I wanted a
"howto" I wont be in this list asking for advice. I need
experience/opinions not how to do things I know how to do things on my
own and to follow a step by step howto you don't need to be
a genius, but the experience advice someone can give you that is not on
a paper is priceless, there is a reason people look at your experience
when you look for a job not at your tittles..(this only means you read
the howtos at school and pass the test but no experience)

That's because, in the best traditions of Open Source solutions, there
is no "one way" to do this. I'll recommend one thing, Joe might
recommend another, Horms another, Nigel another, etc etc (names not
changed to protect the guilty!)

How about you put down a set of specifications and/or criteria to help
us help you?

The question you've asked is vague, to say the least. Do you want:

* Multiple redundant directors (load balancers)?
* Separate webservers, or run them on the director(s)?
* A NAS/SAN or clustered FS, or something more simple?
* To make your MySQL server highly available?
* The whole shebang to be in one location, or spread around?

Do you "own" (ie. have allocated to you) specific IP space that you
control, or will you be using space on another provider's network?

There's a bazillion questions I could ask, but I won't. Simply asking
for a recommendation for a vague concept (which is what you gave) isn't
going to turn out any hard results, I'm afraid.

I'd also suggest that you get some conceptual practice in your lab/test
network by following the basics in the HOWTO until you've got some
rudimentary experience of LVS in practice. Until then, we're likely to
use terminology you may not understand.

Please don't be offended: it's easier for us to help you if you ask
specific questions :)

Graeme

This is fair,

you are right, sorry I think I try cheap out on words because my first
language is Spanish.
is there a Spanish list? ;-)

yes load balance is one of the things I will like to get out of this.
and if is redundant better or at least ready to add one later so it is.

> * Separate webservers, or run them on the director(s)?

3+ apache servers each on his own server(so 3 servers)

something more simple to start.. they only need to pull data from a
mysql db,
and the mysql will be doing replication..


> * To make your MySQL server highly available?

replication is working for me in other setups like this ok so far..

one location for now.

we will have 3 ip's to play with one I was planning for the LVS front,
in the back I was looking into using the MASQ option to have a small lan
inside
I can setup openvpn on the LVS box to have straight access to those in
that lan behind LVS..

I am doing this, and don't worry about terminology..
basically I just need to know something like:

the howto will work for you, but add this solution... or this howto is
for simple setups..
use this other howto someone wrote and this is his homepage.. etc..

No offense, you are right.
