Can I Create Gallera Cluster with two servers ??

Actually I have 6 servers:

2 Server for Load Balancer 2 Server for Apache

Or anyone here can suggest me how to create High Availability Web Server with 6 servers?

Thanks

  • Please try to do your home work and read the [vendor documentation](http://galeracluster.com/documentation-webpages/gettingstarted.html#system-requirements) - Second please to try to confine your questions a single question or at least to a single topic, because that makes answering them easier. – HBruijn Jul 24 '14 at 19:00

Yes you can. This is called a 2 + 1 set-up. 2 Galera nodes + 1 Galera arbitrator sitting on one of the app-server nodes. But it is NOT a recommended set-up.

An alternative would be to put the Load Balancer on the app-servers. Then you have 3 db nodes and 3 app servers. But from the maintenance point of view this is more work than 2 central load balancers.
