学网络编程的人，老是栽在同一个坑里——

理论看完了还是写不出来，源码读完了也不知道从哪儿下手改。

直到我翻到这个开源的宝藏教程：Build Your Own Redis，手把手带你从零硬肝出一个真正能跑的 Redis 服务器。

路线分两段：

先拿 socket 编程开刀，TCP 服务器、事件循环、键值存储，一层层往上搭 再往硬核里冲，哈希表、AVL 树、线程池，真正把底层啃明白

每章都带着代码 + 讲解，拆得够细，步子踩得够稳，跟着撸完你会发现自己是真懂了，不是那种“感觉懂了”。

Introduction

Buildreal-worldsoftware by codingfrom scratch.**If you can build a Redis server, you can build almost any software beyond CRUD!**Because it teaches you 3 fundamental skills:

• Network programming. The next level of programming is programming for multiple machines. Think HTTP servers, RPCs, databases, distributed systems.
• Data structures. Redis is the best example of applying data structures to real-world problems. Why stop at theoretical, textbook-level knowledge when you can learn from production software?
• Low-level C. C was, is, and will be widely used for systems programming and infrastructure software. It’s a gateway to many low-level projects.

**Why from scratch?**A quote from Richard Feynman: “What I cannot create, I do not understand”. You should test your learning with real-world projects!

**Why a book?**The real Redis project is a large code base built with lots of effort. The book distills the core concepts and guides you throughsmall steps.

Recommended Reading

I have curated a list of books that are highly relevant for people who intend to DIY their own Redis.

Beej’s Guide to Network Programming. [Amazon][Web] A comprehensive guide and reference to network programming. It’s a great supplement for coding your own networked apps, as the Redis book doesn’t cover all the details of socket programming.The Linux Programming Interfaceby Michael Kerrisk. [Amazon][Web] The socket API is only a subset of the Linux API interface. You will probably need to become familiar with the other parts, such as IOs, threads and processes, signals, and etc, if you are developing apps for Linux.The C Programming Languageby K&R. [Amazon] Are you scared of C, but still want to follow the project? No problem. This classic book is great for picking up C quickly, whether you are a beginner or an experienced developer.
