Creating a Cluster
if i have four laptops running windows 7 operating system, there is a wireless network within, do i still need to install Couchbase server on all the system to form a clauster/distribution to test the scalabily of Couchbase runing my query program? At what point are the username/password required by the Couchbase server2.0 when adding nodes when form the cluster?
How about the username/password that will be requested along with IP address when adding server node on a cauchbase server administrator interface. At what point were those password created?
Yes you need to install Couchbase on each node of your cluster, but you configure the "cluster" on a single node.
Once you have install all the nodes and configure the cluster on 1 node you can "add" all the other nodes to the cluster. You can do it either from a configured node or from a new node.
During this phase you will have to enter the Administrator username and password.
Here some interesting pointers about Cluster creation and configuration:
2- Add node to the cluster:
UI : Click on Server Tabs and click on the "Add Node" button
CLI : http://www.couchbase.com/docs/couchbase-manual-2.0/restapi-create-new-no...
PS: You are talking about setting up a cluster over a Wifi network, this is OK for development/testing but for production it is always better to have fast and reliable network, so better with cable/fiber.
