Need your advise for new Server setup

[robmorin]

How is it alot??

it is much cheaper to keep customers happy than to spend an extra few bucks..

I have a total of 4 serves as of now with another 3 for redundancy coming soon..
Al servers are in 1 U cases, with military type cpu fan
All servers are AMD 64 X2 running Debian AMD 64 kernel
All servers have (software)mirrored 80 gig drives
All Server have 2 NICS , only one active, other as spare
All servers power source connect to a rebooter , in case we need to reboot from afar, all bios are set to halt on no errors and resume last state as
All servers are on a small ups/then generator
All server mount via NFS dirs from backend server, ie /etc/apache2, /var/www, /var/mail/virtual...
All servers have had wget, curl, fetch and other bad executables chowned to root use only, this drastically reduces exploit attacks and such...

I have
1 Firewall server
2 front end servers
1 backend server

coming soon backup firewall server and backup backend server

Firewall server runs Shorewall and all all my services IPs on it
backend server runs Omega and NFS for front end servers....

I run HAproxy on firewall server that does load balancing and port redirection to front end servers.

All servers ONLY accept connections from each other , other than the firewall....

Its not an expensive set up by far, but when completely finished will make me sleep better at night and keep my clients very happy..

I can add as many front end servers as i wish, plug and play i simply remove a mirror from a current one and duplicate a new one.

I use BackupPC as my backup server, it is very nice... i backup "/" on every pc except /proc /tmp, ect...

I will make a doc on how i did all this when i am finished and i am satisfied all is working ok

if you could go 30days with not logging onto a server via shell, would you not be happy?
