Load Balancing Servers

[ChildOTK]

Good Day,

How would I go about synchronizing a couple servers to accomplish good load balancing?

I have 2 servers in two different data centers and would like to have one as the primary server and two as the secondary server. How would server 2 sync from server 1. It would only be 1 way communication.

Server 2 would be more so a backup server if you will. If server 1 goes down, server 2 takes over. But obviously all sites, their databases and files, and even maybe their account information such as username and password would need to be synced. It would basically be like cloning server 1 but in real time.

Thank you!

I just realized I would need two way communication here, because if server 1 was ever down and changes did in fact occur on server 2, let's say a user signs in to their account and changes a password or something, the database information would have changed. So it would need to be two way syncing / merging where needed.

Short answer, load balancing is not yet available.

You might look into lsyncd for synchronizing files:

lsyncd - Lsyncd (Live Syncing Daemon) synchronizes local directories with a remote targets - Google Project Hosting

It's the only way I know to do this type of function. I wouldn't suggest synchronizing both ways, though, but only one way.

If there are changes on the second machine, simply do a temporary synch back to server 1 and then revert back to one-way synching after that to server2 again.
