Quick Setup of a Redis Enterprise Flash Database

The steps to setup a Redis Enterprise Pack cluster using Redis Enterprise Flash with a single node are simple and are as follows:

  • Step 1: Install Redis Enterprise Pack or launch with Docker container
  • Step 2: Setup a Redis Enterprise Pack cluster with Redis Enterprise Flash
  • Step 3: Create a new Redis Enterprise Flash database
  • Step 4: Connect to your new database

If you are looking for more detailed installation instructions you can visit the installing and upgrading section of the technical documentation.

Step 1: Install Redis Enterprise Pack

Bare Metal, VM, Cloud Instance

To install on bare metal, VM, or instance; download the binaries from the Redis Enterprise Pack download site. Once you have the bits on a Linux based OS, you need to untar the image

$ tar -vxf <downloaded tar file name>

Once the tar command completes, you will find a new install.sh script in the current directory.

$ sudo ./install.sh -y

Docker-based installation

If you prefer, you can also simply run the Redis Enterprise Pack Docker container on Windows, macOS, and Linux

$ docker run -d --cap-add sys_resource --name rp -p 8443:8443 -p 12000:12000 redislabs/redis:latest

Step 2: Setup a Cluster and Enable Redis Enterprise Flash

Direct your browser to https://localhost:8443/ on the host machine to see the Redis Enterprise Pack web console. Simply click the “Setup” button to get started.

Note: Depending on your browser, you may see a certificate error. Simply choose “continue to the website” to get to the setup screen.

On the “node configuration” page, select the “Enable flash storage support” checkbox and provide a cluster FQDN: “mycluster.local“. Then simply click the “Next” button.

Enable Redis Flash

If you don’t have a license key yet, click the “Next” button to try the trial version of the product.
On the next screen, set up a Cluster Administrator account using an email for the login and a password.

Step 3: Create a Database

Select the “new redis db flash” option.

On the “new redis on flash db” page, click the “show advanced option” link and enter “myredisflashdb” for a database name and “12000” for the endpoint port number. Then click “Activate” to create your database.

new redis flash db

You now have a Redis Enterprise Flash database!

Step 4: 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
127.0.0.1:16653> set key1 123
OK
127.0.0.1:16653> get key1
"123"

Connect with a simple Python app

A simple python application running in 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 “redis_test.py

$ vi redis_test.py

Paste the following into a file named “redis_test.py“.

import redis

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

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

$ python redis_test.py

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

set key1 123
True
get key1
b'123'

Now that you have a database, if you’d like to generate load against the database or add a bunch of data for cluster testing, the memtier_benchmark Quick Start should help. However please note that to see the true performance and scale of Redis Enterprise Flash, you will need to tune your IO path and have the flash path set to the mounted path of SSD or NVMe flash memory as that is what it is designed to run on.
