Sometimes it might be useful to synchronize two (or more) CDash instances. Load balancing or fault tolerance are two main reasons. CDash-1-6 implements a very easy way to achieve this by running a continuous cronjob on the backup machine and rsyncing from the main CDash. Here's how we do it:
- Create private/public key pair so that rsync can do its job
- Run the rsync script to get the XML submission files from the main CDash server
- Run the importBuilds.php script to import the new build files into the backup CDash. The importBuilds.php write the last time of a check and makes sure that only new files are being imported.
On the backup machine setup a cronjob:
rsync -r -a -v -z --delete -e "ssh -l cdashuser" maincdashserver:/var/www/CDash/backup/ backupmachine:/var/www/CDash/backupmaincdash/ cd /var/www/CDash && nice php5 importBuilds.php backupmaincdash
