CouchDB is a popular NoSQL database that has made its mark in the world of data storage. With its lightweight design and unique architecture, it has become a go-to solution for many organizations that require a scalable database management system.
In this article, we will take you through the process of installing CouchDB on CentOS 8 and explore its features and use cases.
Installation of CouchDB on CentOS 8
To install CouchDB on a CentOS 8 system, we need to start by enabling the CouchDB repository. We can do this using the following command:
$ sudo rpm –import https://couchdb.apache.org/repo/RPM-GPG-KEY-CouchDB
Once the repository is enabled, we can install CouchDB packages using the dnf command:
$ sudo dnf install couchdb
Configuring CouchDB
After installing CouchDB, we need to configure it before we can start using it. One way to configure CouchDB is by editing the local.ini file.
This file contains various settings that control the behavior of CouchDB. To configure CouchDB, we can use a web-based interface called Fauxton.
Fauxton is a user-friendly interface that allows us to interact with CouchDB in a graphical manner. Using Fauxton, we can create an admin account, set up system databases, and perform various other tasks.
Verifying CouchDB Installation
To verify that CouchDB is installed correctly, we can use the curl command to query the CouchDB server’s API. The curl command should return a JSON formatted response that contains information about the CouchDB server’s current status.
Another way to verify the installation is by accessing the Fauxton web-based interface. We can use our web browser to access the interface by opening the following URL:
http://localhost:5984/_utils/#login
Overview of CouchDB
CouchDB is a NoSQL database that uses JSON structure to store data. Compared to traditional relational databases, CouchDB offers greater flexibility and scalability by omitting the need for a predefined schema.
This means that we can store data in CouchDB without worrying about the data structure beforehand. CouchDB comes with a RESTful HTTP API that allows us to access data from anywhere using standard HTTP requests.
Additionally, CouchDB can be used as a single-node or clustered database, providing scalability to meet the requirements of complex applications.
Use cases for CouchDB
CouchDB is a popular choice for a wide range of data storage use cases. One common use case is document-oriented databases where the structure of data is not fixed.
For instance, social media platforms like Twitter and Facebook use CouchDB to store and query user-generated content. CouchDB is also popular for applications that require real-time data synchronization.
Applications like Trello, a popular project management tool, use CouchDB to provide real-time collaboration across multiple devices.
