I have two dedicated boxes, each using one IP number and hosting named virtual hosts, both with WebMin installed. Box A is a Raq4 and also has a Cobalt System Interface. It is running Cobalt Linux 6.0 and Apache 1.3.12. It currently has 2 active virtual hosts, with more coming on line. Box B is running Redhat Linux 7.2 and Apache 1.3.20. What is needed: 1.) Apache configuration file on Box B to mirror the VitualHosts of Box A. 2.) DocumentRoot directory structure on Box B to mirror Box A. (These first two are being done by myself but will require checking) 3.) Rsync installation on both boxes and daemons started. 4.) Hourly crontabs started from each machine to reflect changes (non-destructive, of course!) in DocumentRoot(s) in the other, offset by 1/2 hour to each other. 5.) DNS/BIND services started on both boxes and implemented where Box A would be Primary Name Server for half of the virtual hosts and Secondary for rest, and Box B would handle things in the opposite fashion. In other words, for sites numbered 1-4, all would be mirrored on both Boxes. Box A would be the Primary Name Server for 1 & 2 and Secondary for 3 & 4. Box B would be the Primary Name Server for 3 & 4 and Secondary for 1 & 2. 6.) Registry of the two as name servers with ICANN. 7.) An automated e-mail to be sent out when one box realizes that the other has gone down. This is important, since the arrangement is to ensure both continuous uptime of the sites, shared bandwidth loads and data integrity. Note: MySQL databases have not been used yet but are planned for in the future and will need to be anticipated in the implementation. If you require more information than I give here, please feel free to ask in the forum.
