redis-cli practical examples

In this post we'll review the most useful and used commands when working with redis-cli, with practical examples.

Without authentication/TLS

Let's assume that our Redis instance has this properties:

host : 10.20.30.40

port : 1234

Connect to Redis Instance:

redis-cli -p 1234 -h 10.20.30.40

Once connected you can:

Get all keys:

redis> keys *

delete all keys from all Redis databases:

redis> FLUSHALL

delete all keys of the current Redis database only:

redis> FLUSHDB

set a key with its value:

redis> SET mykey "hello"

get mykey:

redis> GET mykey

set a key with expiration (in seconds):

redis> set secondkey "hey" EX 90

With authentication/TLS:

Let's assume that our Redis instance has this properties:

host : 10.20.30.40

port : 1234

auth-string: abdcefgh

ca-certificate: ca-cert.pem

Connect to Redis Instance using TLS:

export REDISCLI_AUTH=abcdefgh

redis-cli -p 1234 -h 10.20.30.40 --tls --cacert=ca-cert.pem
