Redis is an open-source, in-memory data structure store, used as a database, cache, and message broker. It is known for its high performance and flexibility. In this guide, we will walk you through the installation of Redis on Ubuntu 22.04. Whether you are deploying it on a local server or using a Windows VPS UK, this tutorial covers all the necessary steps.
Step 1: Update Your System
Before installing Redis, ensure your system is up to date. Run the following commands:
sudo apt update && sudo apt upgrade -yKeeping your system updated is crucial for security and performance, whether you're setting it up locally or on a VPS Windows Servers platform.
Step 2: Install Redis
To install Redis, run the following command:
sudo apt install redis-server -yThis command will download and install Redis along with its dependencies.
Step 3: Configure Redis
After installation, you may want to configure Redis. Open the Redis configuration file:
sudo nano /etc/redis/redis.confLook for the line that says supervised no and change it to:
supervised systemdThis will allow Redis to be supervised by systemd. Save and exit the file.
Step 4: Start Redis Service
To start the Redis service and enable it to start on boot, run the following commands:
sudo systemctl start redis
sudo systemctl enable redisYou can check the status of the Redis service with:
sudo systemctl status redisStep 5: Test Redis Installation
To ensure Redis is working correctly, you can use the Redis CLI tool:
redis-cliOnce in the Redis CLI, you can test it by running:
pingYou should receive a response of PONG, indicating that Redis is functioning correctly.
Step 6: Configure Redis to Require a Password (Optional)
For added security, you can configure Redis to require a password. Open the Redis configuration file again:
sudo nano /etc/redis/redis.confFind the line that says # requirepass foobared and change it to:
requirepass your_passwordReplace your_password with a strong password of your choice. Save and exit the file, then restart Redis:
sudo systemctl restart redis
