This tutorial walks you through installing MongoDB on three CentOS 7.9 servers, configuring a replica set with a master and two slaves, creating admin and test users, securing communication with key files, and verifying failover by stopping the primary node, all illustrated with commands and screenshots.
This tutorial walks you through adding MongoDB dependencies to a Spring Boot project, configuring the connection, defining entity and repository classes, implementing service and controller layers, and optionally setting up sharding or replica‑set architectures for scalable data management.
This article explains MongoDB's three cluster architectures—deprecated Master‑Slave replication, the highly available Replica Set with automatic failover, and horizontal scaling Sharding—detailing their roles, data flow, advantages, limitations, and operational considerations for building reliable, scalable databases.
This article explains MongoDB's evolution from Master‑Slave to Replica Set and Sharding architectures, detailing how each model provides high availability, data reliability, and scalability, and offers practical configuration tips to ensure strong consistency and minimal downtime in production deployments.
This guide explains MongoDB replica set fundamentals, walks through local deployment of a primary‑secondary‑secondary cluster, demonstrates automatic failover, and details write concern and read preference options—including member attributes, connection string parameters, and shell commands—for reliable high‑availability data handling.
This step‑by‑step tutorial shows how to set up a highly available MongoDB cluster with sharding and replica sets on Ubuntu 18.04, covering key concepts, environment preparation, configuration of config servers, shard replica sets, the mongos router, enabling sharding, testing data distribution, and final deployment tips.
This article explains MongoDB’s key features, compares its advantages and disadvantages, and provides a detailed, step‑by‑step guide to installing, configuring, and verifying a replica set on CentOS 6.6, including commands for package installation, configuration file editing, service startup, node addition, and data synchronization verification.
This guide explains MongoDB read preference options, write concerns, authentication setup, replica set configuration, and connection best practices with PHP examples, helping developers improve database performance and avoid common pitfalls in production environments.
This guide details a production‑grade MongoDB replica‑set deployment, covering hardware specs, configuration files, replica‑set initialization, user creation, incremental backup with mongobackup scripts, primary node switching, cold backup procedures, troubleshooting authentication errors, and test data generation for performance validation.
This tutorial shows how to create a three‑node MongoDB replica set using Docker, configure automatic primary election, verify data synchronization across secondaries, and simulate a primary failure to observe failover, providing a practical guide for high‑availability database deployments.
