Redis Commands
Redis commands are used to perform operations on the Redis service.
To execute commands on the Redis service, you need a Redis client. The Redis client is included in the Redis installation package we downloaded earlier.
Syntax
The basic syntax of the Redis client is as follows:
$ redis-cli
Example
The following example explains how to start the Redis client:
Start the Redis server, open a terminal and enter the commandredis-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 connected to the local Redis service and executed thePINGcommand, which is used to check whether the Redis service has started.
Executing Commands on a Remote Service
If you need to execute commands on a remote Redis service, we also use theredis-clicommand.
Syntax
$ redis-cli -h host -p port -a password
Example
The following example demonstrates how to connect to a 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 PONGOther extensions
