How to connect to Redis database using different methods

by | Sep 18, 2020

Do you confuse about how to connect to a Redis database?

Luckily, it is an easy process to connect to a Redis database using different commands like redis-cli.

As a part of our Server Management Services, we help our Customers with several database-related tasks regularly.

Let us today discuss the possible steps for connecting to Redis databases.

What is Redis?

Redis is an open-source, in-memory key-value data store that used as a database, cache, and message broker.

Frequently, customers need to connect to the Redis database if it installed locally or in a remote instance to perform most operations.

Here, let us see how to connect to Redis from the command line, how to authenticate and test the connection, as well as how to close a Redis connection.

For instance, in Ubuntu 18.04 server running Redis version 4.0.9 using redis-cli,

 

Connecting to Redis(Locally)

If you have Redis-server installed locally, we can connect to the Redis instance with the below command:

redis-cli

Basically, after running the above command we are in a Redis-cli’s interactive mode which presents with a read-eval-print loop (REPL) where we can run Redis’s built-in commands and receive replies.

In interactive mode, the command-line prompt will change to reflect the connection. The prompt indicates a connection to a Redis instance hosted locally (127.0.0.1) and accessed over Redis’s default port (6379).

127.0.0.1:6379>

Also, the alternative to running Redis commands in interactive mode is given below,

redis-cli redis_command

 

Connecting to Redis(Remotely)

Similarly, the command that uses to connect to the remote Redis database,

redis-cli -h host -p port_number -a password

Additionally, with a Redis password, clients will be able to connect to Redis even not include the -a flag in their redis-cli command. But, they not allowed to perform any actions like add, change, or query data until they authenticate. In order to authenticate after connecting, we use the below auth command followed by the password:

127.0.0.1:6379> auth password

If the password is correct, it brings an OK message whereas it will return an error.
