Redis command

Redis commands are used to perform operations on the redis service.

To execute commands on the redis service, a redis client is required. The Redis client is in the redis installation package we downloaded before.

Syntax

The basic syntax of the Redis client is:

$ redis-cli

Example

The following example explains how to start the redis client:

Start the redis client, open the terminal and enter the command redis-cli. This command will connect to the local redis service.

$redis-cli
redis 127.0.0.1:6379>
redis 127.0.0.1:6379> PING

PONG

In the above example, we connect to the local redis service and execute the PING command, which is used to detect whether the redis service is started.

Execute commands on the remote service

If you need to execute commands on the remote redis service, we also use the redis-cli command.

Syntax

$ redis-cli -h host -p port -a password

Example

The following example demonstrates how to connect to the redis service with host 127.0.0.1, port 6379, and password mypass.

$redis-cli -h 127.0.0.1 -p 6379 -a "mypass"
redis 127.0.0.1:6379>
redis 127.0.0.1:6379> PING

PONG
