    Hi David,

    Thanks for this explanation.

    I have a question for you.

    That plugin is ready?

    I’ve set this up, but it doesn’t seem to replicate owner/group. Am I missing something?

      Hi – it should do – but if it’s not, what happens if you change the owner on the parent folders on each node? Do new files then inherit the parent? If you still have issues, contact me through our on-site chat.

    Hey, so if I set this up hosting a forum site and I updated the form software (For some reason I was connected to node2 through the load balancer) will the updated php files etc be synced across to the other servers?

    On this article I can’t find where the node2 and node3 would send data to the node1 server?

    Finally, is it good practice to simply sync the entire /var/www directory? I’ll be hosting a few sites on this setup and would make it much easier to update them.

    Am I right in thinking that to add a new node it is as simple as adding this to my node1 crontab?
    * * * * * unison -batch /var/www/wpicluster ssh:// &> /dev/null

    Thanks in advance for answering these questions.

      Hi – there are two aspects to adding an extra node. One is file synchronisation, using Unison. The other is adding an extra node with your database.
