I use rsync for the same purpose (and to make local backups of the data on the web servers). How busy do you expect the boxes to be? I'm not sure running it every minute is desirable, but if they are not particularly heavily loaded, it should be fine. Be prepared to tweak, though, until you find the right balance between performance and synchronous data. As for passwords and permissions, I guess you are talking about passwords etc for access to .htaccess-protected areas? If so, make sure your passwd database (the apache-specific one, not the /etc/passwd!) is included in the rsync runs. rsync will allow you to preserve file ownership and permissions during the transfer, so this shouldn't be a worry - just read the man page and select the appropriate options. Depending on how sophisticated you want to be, you can run the rsync in job in pull mode from the slave server, so it can restart the web server if you change its config on the master machine. The possibilities are endless, though. Play with it and have fun! Dan > Thanks for your help in advance.
