[webmin-l] My Plan

[RYAN M. v. G. <lu...@co...>]

Here is my rough plan I have two servers in different remote locations both running virtualmin.  What i would like to do is have complete redundancy on both and use some sort of round robin dns to take over if one site goes down.  Seems like virtualmin has all the tools but it is also very new to me.  I already have things setup on one server the way i liked before installing webmin lets call it master. 

Phase one is give control of all existing virtual sites to webmin on master sever.

During the import process webmin seems to always want to set the ipaddress this is not portable enough for me.  Also i am have some ip issues with my isp right now and need to be able to change in the future.  

Ideally I wish virtualmin to be able to use the *:80 setting for all virtual server but it keep using an ip address.  How do i achieve this.

Backup/move all virtual servers once per day to the slave.

clash as user already exists?

Edit dns records to use some sort of round robin.

Hi Ryan

the other problem to consider with your proposed set-up is how your 
customers will collect their e-mail if it's on the back-up server

i.e. if main server is down for an hour and all e-mails go to back-up server

how do customers collect e-mails - as they will probably only be using 1 pop 
account and outlook express which will be looking to collect from 
mail.domain.tld

both servers will have a mail.domain.tld - but the customers mail software 
will only look at the "live" server

i've got a set-up where e-mails are queued on the back-up server until the 
main server goes live again
then the main server accepts the back-up server's mail queue

this obviously means that the customer can't get any new e-mails whilst the 
main server is down - but none should bounce back either

SSL domains with their own IP numbers need a way of accepting the back-up 
server's extra IP numbers as well

virtulamin does most things - but i've not seen how it can do the above

i paid a lot for a customised failover system as i'm not a techie
but it does what i require
if you want the details of the company i use let me know

Regards

Martyn

Hi Ryan,

I think you wnat to installa a webmin cluster service, which really means
that you have multiple webmin servers running as one face to the =
customer.
A real cluster.

I never tried this before, but when it comes to a failover system and you
loose one webmin server for your clients, where do your customers get =
their
eMails from during this period?

So if you already have one server going why not do a complete backup of =
the
system and try to cluster your machines?

If not - I'm lost.
