Default Load balancing and increase availability

Hi thanks to your great tutorials I successfully configured my first web server. I followed this tutorial here http://www.howtoforge.com/perfect-se...ot-ispconfig-3
Right now I just have a low-end vps and I would like to balance the load with another vps and increase the website availability too (like in case one vps goes down the other one takes all the traffic). I dont have an high budget, which easy and cheap way do you suggest me to do that?

Thanks for your help

Have you considered this tutorial, which describes multi-server setup?

Thanks for your answer but this kind of configuration doesnt balance the load of the web server, it just divides the servers by service. And it also doesnt provide a solution in case one server is down. I was thinking of something with a maximum of 3 servers that balance their load and copy each other and in case one is down the other 2 still work / balance their load. Is this kind of configuration possible?

Hi,

I have similar question. I am looking for a tutorial for this scenario:

I would like to configure 2 servers (ISPConfig3 on Ubuntu 12.04, web and emails) in 2 different offices. One as a master, 2nd one as a slave. If master will go down, slave should switch automatically and accept all emails and web traffic. Is it possible? Any tips or suggestions are welcome

Regards

Artur

Hi Artur,

if you wonīt use a load-balancer or a fail-over-ip, you can also use your dns-records.

If server A canīt reach server B, A replaces the DNS-Records with the IP of server A - and vice versa. But this could result in a single point of failure.

Anyway, you must keep the data on both serves always in sync. For the databases use a replication, for the filesystem something like drbd or unision.
