Using Redis with Ruby
In order to use Redis with Ruby you will need a Ruby Redis client. In the following sections, we will demonstrate the use of redis-rb, a Ruby client library for Redis. Additional Ruby clients for Redis can be found under the Ruby section of the Redis Clients page.
redis-rb’s installation instructions are given in the README file. Use
gem to install redis-rb:
$ gem install redis
redis-rb in your Gemfile by adding to it the following line:
Followed by executing
Opening a Connection to Redis Using redis-rb
The following code creates a connection to Redis using redis-rb:
require 'redis' redis = Redis.new ( :host => 'hostname', :port => port, :password => 'password')
To adapt this example to your code, make sure that you replace the following values with those of your database:
- In line 4, the
:hostshould be your database’s hostname or IP address
- In line 5, the
:portshould be your database’s port
- In line 6, the
:passwordshould be your database’s password
Using SSL and redis-rb
Reading and Writing Data with redis-rb
Once connected to Redis, you can start reading and writing data. The following code snippet writes the value
bar to the Redis key
foo, reads it back, and prints it:
# open a connection to Redis ... redis.set('foo', 'bar'); value = redis.get('foo'); puts value
The output of the above code should be:
$ ruby example_redis-rb.rb bar
Redis Enterprise enables running Redis datasets in a highly available and auto-scalable manner, with predictable top performance.
The Redis Enterprise Software lets you install an enterprise grade Redis cluster in your environment of choice, whether an on-premises data-center or your preferred cloud platform. It gives you full control of your data and configuration – no clustering or sharding knowledge required!
Redis Enterprise Cloud is a fully-managed cloud service for hosting and running Redis dataset without dealing with nodes, clusters, failure recovery or performance stabilization. Our technology does all that in a fully automated manner. Redis Enterprise Cloud is available on all popular clouds and platforms-as-a-service.
