Configure Unison on Ubuntu

To get Unison running first set up passwordless SSH authentication between the two hosts you want to sync. Then update the default Unison configuration file which can be found at /root/.unison/default.prf.

A simple configuration file to synchronize the /var/www/ and /var/www/ folder would look like this.

Unison preferences file # Set the source and destination folder that should be synced root = /var/www/ root = ssh://root@ # If you only want to sync specific subfolders specify them here # If you want to sync the full root folder, delete the path lines path = path = # Enable to run Unison silently in the background batch = true

Test the configuration by running the command unison in the terminal. To automatically sync the folders every two minutes add a cronjob like

*/2 * * * * /usr/bin/unison &> /dev/null
