Redis Server

Redis Server commands are used to manage Redis Server. There are different server commands which can be used to fetch server information, statistics and other characteristics of server.

Example

Let's take an example to see how to get all statistics and information about the server.

redis 127.0.0.1:6379> ping
PONG
redis 127.0.0.1:6379> AUTH "password"
(error) ERR Client sent AUTH, but no password is set
redis 127.0.0.1:6379> PING
PONG
redis 127.0.0.1:6379> ECHO "Welcome to Javatpoint"

Redis Server Commands

Following is a list of some server commands used in Redis database:

Index	Command	Description
