First-Time Setup
================

CouchDB 2.0 can be used in a single-node or clustered configuration.
Below are the first-time setup steps required for each of these
configurations.

.. _install/setup/single:

Single Node Setup
=================

A single node CouchDB 2.0 installation is what most users will be using.
It is roughly equivalent to the CouchDB 1.x-series. Note that a
single-node setup obviously doesn't take any advantage of the new
scaling and fault-tolerance features in CouchDB 2.0.

After installation and initial startup, visit Fauxton at
``http://127.0.0.01:5984/_utils#setup``. You will be asked to set up
CouchDB as a single-node instance or set up a cluster. When you click
“Single-Node-Setup”, you will get asked for an admin username and
password. Choose them well and remember them. You can also bind CouchDB
to a public port, so it is accessible within your LAN or the public, if
you are doing this on a public VM. The wizard then configures your admin
username and password and creates the three system databases _users,
_replicator and _global_changes for you.

Alternatively, if you don't want to use the “Single-Node-Setup” wizard
and run 2.0 as a single node with admin username and password already
configured, make sure to create the three three system databases manually
on startup:

.. code-block:: sh

    curl -X PUT http://127.0.0.1:5984/_users

    curl -X PUT http://127.0.0.1:5984/_replicator

    curl -X PUT http://127.0.0.1:5984/_global_changes

See the next section for the cluster setup instructions.

.. _install/setup/cluster:

Cluster Setup
=============

As configuration has many steps, see the :ref:`Cluster Reference Setup
<cluster/setup>` for full details.
