synchronising failover web servers

[ari at ish.com.au (Aristedes Maniatis)]

So, say you have to update /usr/local/etc/httpd.conf. Would your 
process be this:

* checkout cvs onto your workstation
* change httpd.conf
* check into cvs
* log into server
* update cvs repository
* run Makefile script which installs httpd.conf in the correct location 
from the cvs repository and then executes 'apachectrl graceful'.
* repeat on secondary standby machine by running a Makefile which uses 
ssh to trigger a remote Makefile

I've never really liked Makefiles, but I guess we could do something 
very similar with shell scripts.

Thanks for the info. But what do you do about synchronising data 
directories (eg. /usr/local/etc/www/data). In those cases you very 
often can't put them into cvs. Do you use Unison or something similar?
