How to install and configure php redis extension in Windows environment

Redis is a high-performance open source in-memory database that provides key-value storage, publish/subscribe, scripting and other functions. In PHP development, redis, as an efficient caching system, is widely used in scenarios such as distributed caching and session storage.

2. Install Redis service

1) Create a configuration file named redis.windows.conf in the C:\redis directory.

2) Modify the content in the redis.windows.conf file:

port 6379
requirepass your_password

3) In the cmd command line, open it as an administrator, enter the C:\redis directory, and run the following command to install the redis service:

redis-server.exe --service-install redis.windows.conf --service-name Redis --port 6379
