Surachart Opun's Blog: Learned Couchbase

As you know, Couchbase is the open source NoSQL database for interactive web and mobile applications. I plan to read a book about Developing with Couchbase Server. First of all, I had to install it. I chose "Community Edition" for my test. If you will implement it you can choose Enterprise Edition and read more.
- Installed in on my host (centos):

[surachart@centos ~]$ wget --continue http://packages.couchbase.com/releases/2.0.0/couchbase-server-community_x86_64_2.0.0.rpm

- Opened browser and setup.
On Step 1: Chose "Join a cluster now"

Clicked "Next"

Saw server has been associated with the cluster.

This page showed rebalance operation.

I thought it's ok for installation. I will configuration more later, then tested with some commands.
