Install and use the redis cache program in windows

Some time ago, the company needed to use redis to implement the cache function. Therefore, I wrote this article to share the installation and usage skills of redis.

First, download the redisserver and execute redis-server.exe. This process must be enabled all the time. We can also download a redis management tool: phpRedisAdmin

To facilitate the management of redis setting values, you need to pay attention to some specifications when setting their key values. For example, we have three systems running on the same server at the same time, and all of them use redis for caching, if one of the key values in the system is repeated, it will be overwritten by the later settings.

The following is a redis predis usage encapsulation class written by myself.
