Redis (i)----configuration and installation

1. Redis Download

Download the appropriate package according to your operating system platform: Https://github.com/MSOpenTech/redis

2. The Redis installation (1) is extracted and then placed in any directory.         This example: D:\Program Files\redis. (2) Start Redis under cmd:

• To create a new run-redis.bat in D:\Program Files\redis, open it with Notepad and edit the following: Redis-server.exe redis.conf, save, double-click Run.
• The following results show that the execution succeeded:

You can see that the Redis service port is 6379.

(3) configuration file for Redis: D:\Program files\redis\redis.conf
