How To Install and Secure Redis on Ubuntu 18.04

In this tutorial, we will guide you through the process of installing and securing Redis on Ubuntu 18.04.

Step 1: Update your system

Before we start, let's make sure that our system is up to date by running the following command:

sudo apt update && sudo apt upgrade -y

Step 2: Install Redis

To install Redis, run the following command:

sudo apt install redis-server

Step 3: Configure Redis

By default, Redis is configured to listen on all network interfaces. This can be a security risk. To mitigate this risk, we will configure Redis to listen only on the localhost.

Open the Redis configuration file using the following command:

sudo nano /etc/redis/redis.conf

Find the line that starts with bind and change it to:

bind 127.0.0.1

Save and exit the file by pressing Ctrl+X, then Y, and finally Enter.

Step 4: Restart Redis

After making changes to the configuration file, we need to restart Redis for the changes to take effect:

sudo systemctl restart redis

Step 5: Test Redis

To test Redis, run the following command:

redis-cli ping

If Redis is working properly, you should see the following output:

PONG

Step 6: Secure Redis

To secure Redis, we will enable authentication. Open the Redis configuration file again:

sudo nano /etc/redis/redis.conf

Find the line that starts with # requirepass and uncomment it by removing the # at the beginning of the line. Then, replace yourpassword with a strong password:

requirepass yourpassword

Save and exit the file by pressing Ctrl+X, then Y, and finally Enter.

Restart Redis:

sudo systemctl restart redis

Step 7: Test Authentication

To test authentication, run the following command:

redis-cli -a yourpassword ping

If authentication is working properly, you should see the following output:

PONG

Congratulations, you have successfully installed and secured Redis on Ubuntu 18.04!
