Popular languages look quite similar: you create a Redis object and executeĬommands calling methods. These instructions are Ruby specific but actually many library clients for

RUN UNIX COMMANDS IN RUBY RUNNER INSTALL

You can install it using the command gem install redis.

You'll find a full list of clients for different languages in this page.įor instance if you happen to use the Ruby programming language our best advice In order to do so you need toĭownload and install a Redis client library for your programming language. The goal is to use it from your application. Of course using Redis just from the command line interface is not enough as After the firewall is in place, try to connect with redis-cli from an external host in order to prove yourself the instance is actually not reachable. Note that a Redis instance exposed to the internet without any security is very simple to exploit, so make sure you understand the above and apply at least a firewall layer.

Use spiped or another SSL tunneling software in order to encrypt traffic between Redis servers and Redis clients if your environment requires encryption.

Use the requirepass option in order to add an additional layer of security so that clients will require to authenticate using the AUTH command.

For example only the loopback interface (127.0.0.1) if you are accessing Redis just locally from the same computer, and so forth.

Use a configuration file where the bind directive is set in order to guarantee that Redis listens on only the network interfaces you are using.

Make sure the port Redis uses to listen for connections (by default 6379 and additionally 16379 if you run Redis in cluster mode, plus 26379 for Sentinel) is firewalled, so that it is not possible to contact Redis from the outside world.

If you are not 100% sure your environment is secured properly, please check the following steps in order to make Redis more secure, which are enlisted in order of increased security. Is exposed to the internet, it is a big security concern.

If you use Redis in a very controlled environment, separated from theĮxternal internet and in general from attackers, that's fine. Securing Redisīy default Redis binds to all the interfaces and has no authentication atĪll. Otherwise if you already know a few basic Redis commands you can keep reading. It is the right time to pause a bit with this tutorial and start the fifteen minutes introduction to Redis data types in order to learn a few Redis commands. Redis 127.0.0.1:6379> set mykey somevalueĪt this point you are able to talk with Redis. You can type different commands and see their replies.

You can change the host and port used by redis-cli - just try the -help option to check the usage information.Īnother interesting way to run redis-cli is without arguments: the program will start in interactive mode. Running redis-cli followed by a command name and its arguments will send this command to the Redis instance running on localhost at port 6379. The first thing to do in order to check if Redis is working properly is sending a PING command using redis-cli: $ redis-cli ping However to make hacking with Redis simpler Redis provides a command line utility that can be used to send commands to Redis. This protocol is implemented in the Redis client libraries for the different programming languages. Exploring Redis with the CLIĮxternal programs talk to Redis using a TCP socket and a Redis specific protocol. Once you have Redis up and running, and can connect using redis-cli, you can continue with the steps below. See the guide below that best fits your needs: How you install Redis depends on your operating system.

You'll learn how to install, run, and experiment with the Redis server process. This is a guide to getting started with Redis.
