Building a Redis Client from Scratch in C++ (Part 2) | Connecting to Redis Server
In Part 2 of our Redis CLI project, we take a major step forward by establishing a connection to the Redis server. We implement the connectToServer function using Berkeley sockets, ensuring our CLI can successfully communicate with Redis. Along the way, we introduce a structured project layout with CLI.h, CLI.cpp, RedisClient.h, RedisClient.cpp, and a Makefile for compilation.
🔹 Topics Covered:
✅ Created project structure: CLI and RedisClient classes
✅ Implemented connectToServer to establish a TCP connection
✅ Updated main.cpp to integrate connection testing
✅ Compiled and tested using Makefile
