At current stage I have two servers installed, whereby the first one
does all, but the second is a database server.
I need to install on different location a server pair, which should work
together, fail-fall-over, ...
The idea is to have in the dns for the servers:
abc.example.com <== general term
tw.abc.example.com <== redirected to, if the user is closer to Taiwan
de.abc.example.com <== redirected to, if the user is closer to Germany
abc will be in my office (10Mbps), tw.abc & de.abc are server
co-location with each 150 Mbps.
The database server is connected to the web server via second Ethernet
port and a private IP (192.168.x.x) via cross over cable.
The other ethernet port of the web server is connected to the Internet
(either through another ADSL, like at my office) or to like the web
server directly to the Internet HUB.
The mySQL servers should be set-up as a cluster server and should work
together within a VPN.
Questions:
1. Any hints on above configuration?
2. Has anybody experience with a cluster mysql?
3. How to get the web servers working with the closest connection
(according to the users IP) ?
4. How do I get info about the users IP (within the web server) to
provide startup settings, like Time zone & so time of the user,
language, country, ... ?
5. How to make it fail-fall-over if one of the server (web and/or
database server!) is not working?
Thanks for you input!
bye
Ronald
