I'm curious what other people do about syncing your config files between
When I've got this all implemented, I'm planning to hand it to a network
engineer and I'd like to give him a more elegant way to keep the config
files in sync then 'make the same edits to the file on each host'
method. I was thinking of a solution with an nfs share and a cron job
running on the other host, like..
host1: shares /var/dhcpd_config to host2.
edit /etc/dhcpd.master (included by /etc/dhcpd.conf) on host1. Copy it
to /var/dhcpd_config and restart dhcpd.
cron job on host2 sees change to /var/dhcpd_config/dhcpd.master, copies
it to /etc, restarts dhcpd.
Fairly simple. Of course I'd do stuff like preserve the old version,
etc, and use iptables to make sure only host2 can access the share. How
do you handle this?
