Testing client connectivity

In various scenarios, such as after creating a new cluster or upgrading the cluster, it is highly advisable to verify client connectivity to the database.

To test client connectivity:

  1. Create a Redis database and get the database’s endpoint, which contains the cluster name (FQDN). For additional details, refer to Creating a new database.
  2. Try to connect to the database endpoint from your client of choice, and execute commands against the database.
  3. If the database does not respond, try to connect to the database endpoint by using the IP address rather than the FQDN; if you succeed, it means that the DNS is not properly configured. For additional details, refer to DNS.

If any issues are encountered during the connectivity test, contact our support at

Test Connecting to your Database

With the Redis database created, you are ready to connect to your database to store data. You can use one of the following ways to test connectivity to your database:

  • Connecting with redis-cli, the built-in command-line tool
  • Connecting with a “hello world” application using Python.

Connecting Using redis-cli

Run redis-cli, located in the /opt/redislabs/bin directory, to connect to port 12000 and store and retrieve a key in database1

# sudo /opt/redislabs/bin/redis-cli -p 12000> set key1 123
OK> get key1

Connect with a simple Python app

A simple python application running on the host machine can also connect to the database1.

Note: The following section assumes you already have python and redis-py (python library for connecting to Redis) configured on the host machine running the container. You can find the instructions to configure redis-py on the github page for redis-py.

In the command-line Terminal, create a new file called “

$ vi

Paste the following into a file named ““.

import redis

r = redis.StrictRedis(host='localhost', port=12000, db=0)
print ("set key1 123")
print (r.set('key1', '123'))
print ("get key1")

Run “” application to connect to the database and store and retrieve a key using the command-line.

$ python

The output should look like the following screen if the connection is successful.

set key1 123
get key1
