How To Install Apache CouchDB on Ubuntu 20.04 LTS

Install Apache CouchDB on Ubuntu 20.04

In this tutorial, we will show you how to install Apache CouchDB on Ubuntu 20.04 LTS. For those of you who didn’t know, CouchDB is an open-source project and NoSQL, document-oriented database server developed by the Apache Software Foundation. It 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.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation Apache CouchDB on a Ubuntu 20.04 (Focal Fossa) server.

Install Apache CouchDB on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running these following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Installing Apache CouchDB on Ubuntu 20.04.

CouchDB officially presents on the Ubuntu default repository. Run the following command to install Apache CouchDB:

sudo apt install couchdb

The installer will ask you whether you want to install CouchDB in a clustered or standalone mode. A cluster means multiple servers connected together, working as a single, distributed data store.

During the installation, you should see messages to select some option:

Step 3. Accessing Apache CouchDB.

Apache CouchDB will be available on HTTP port 5984 by default. Open your favorite browser and navigate to localhost:5984/_utils/ and complete the required steps to finish the installation or run the following curl command that will print information about the CouchDB database in JSON format:

curl http://127.0.0.1:5984/

Results:
