However, some of its default configuration settings are insecure and provide malicious actors with opportunities to attack and gain access to your server and its data. With that, your Redis installation is fully operational and ready for you to use. In the prompt that follows, test connectivity with the ping command:Įxit out into the shell again when you are finished: To test that Redis is functioning correctly, connect to the server using the command-line client: If, however, you prefer to start up Redis manually every time your server boots, you can configure this with the following command:
![npm install redis npm install redis](https://linuxhint.com/wp-content/uploads/2018/10/4-14.png)
Note: This setting is desirable for many common use cases of Redis. Here, you can see that Redis is running and is already enabled, meaning that it is set to start up every time the server boots.

Start by checking that the Redis service is running: We will go over a handful of ways to check that Redis is working correctly in this step. Step 2 - Testing RedisĪs with any newly-installed software, it’s a good idea to ensure that Redis is functioning as expected before making any further changes to its configuration. Before you begin using it, though, it’s prudent to first check whether Redis is functioning correctly. With that, you’ve installed and configured Redis and it’s running on your machine. Then, restart the Redis service to reflect the changes you made to the configuration file: That’s the only change you need to make to the Redis configuration file at this point, so save and close it when you are finished. # They do not enable continuous liveness pings back to your supervisor. # Note: these supervision methods only signal "process is ready." # UPSTART_JOB or NOTIFY_SOCKET environment variables # supervised auto - detect upstart or systemd method based on # supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET # supervised upstart - signal upstart by putting Redis into SIGSTOP mode # supervised no - no supervision interaction

# If you run Redis from upstart or systemd, Redis can interact with your Since you are running Ubuntu, which uses the systemd init system, change this to systemd: The supervised directive is set to no by default.
![npm install redis npm install redis](https://i.stack.imgur.com/G53Nl.png)
This directive allows you to declare an init system to manage Redis as a service, providing you with more control over its operation. Inside the file, find the supervised directive. Open this file with your preferred text editor: Following this, there is one important configuration change to make in the Redis configuration file, which was generated automatically during the installation.

In order to get the latest version of Redis, we will use apt to install it from the official Ubuntu repositories.įirst, update your local apt package cache if you haven’t done so recently: Step 1 - Installing and Configuring Redis When you are ready to begin, log in to your Ubuntu 18.04 server as your sudo user and continue below. You can set this up by following our Initial Server Setup guide. To complete this guide, you will need access to an Ubuntu 18.04 server that has a non-root user with sudo privileges and a basic firewall configured.
