This article is to share with you about the basic installation judgment of redis and the examples of how to launch it. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The basic installation judgment and startup method of redis are as follows:

1. Whether Redis is installed or not (the following code will appear after installation)

[root] $whereis redis-cliredis-cli: / usr/local/bin/redis-cli [root] $[root] $whereis redis-serverredis-server: / usr/local/bin/redis-server

2. Start Redis

Enter code
