CouchDB is an open-source database, and was first released in 2005 and later became an Apache Software Foundation project in 2008. Apache CouchDB™ lets you access your data where you need it.

CouchDB has a document-oriented NoSQL database architecture and is implemented in the concurrency-oriented language Erlang; it uses JSON to store data, JavaScript as its query language using MapReduce, and HTTP for an API.

1. Upgrade your system

You need to upgrade your system software to the latest version before proceeding with the installation of CouchDB.

 # yum update

Make sure the EPEL repository is present on the server, if it is not, try running this command.

# yum install epel-release

2. Add Apache repository

Before proceeding with the CouchDB installation, you may need to add the apache repository.

Create a file named apache.repo in the location /etc/yum.repos.d and edit the file and add the contents.

# vi /etc/yum.repos.d/apache.repo
[bintray--apache-couchdb-rpm]
name=bintray--apache-couchdb-rpm                          baseurl=http://apache.bintray.com/couchdb-rpm/el$releasever/$basearch/
gpgcheck=0
repo_gpgcheck=0
enabled=1

3. Install Apache CouchDB

Run the following command.

#  yum install couchdb

4. Configure Apache CouchDB

When the installation is finished, run the following commands to start and enable CouchDB.

# systemctl start couchdb
# systemctl enable couchdb

Verify the CouchDB is running or not by running the following command.

# systemctl status couchdb

You will get a output simialar as below if the installation was done properly.

 # systemctl status couchdb

6. Enable Fauxton Web GUI Administration Panel

Fauxton is a web-based interface built into CouchDB. It provides interface with the ability to manage documents, views and various configuration settings.

Modify the file:

# vi /opt/couchdb/etc/default.ini

Go to the line “[chttpd]” and edit the bind_address value with your IP address.

[chttpd]
; These settings affect the main, clustered port (5984 by default).
port = 5984
bind_address = 198.26.36.203

Restart CouchDB:

  # systemctl restart couchdb

Open the URL with your IP address in the web browser.

http://98.26.36.2103/_utils/

7. Creating an Administrator User in Fauxton

Open the URL with your IP address.

http://198.26.36.203:5984/_utils/#createAdmin

Enter your desired admin username and password.

That’s it. Now if you want to log in again the Fauxton Web GUI interface will ask you for your login credentials.
