How to Install Redis® on Ubuntu 24.04?

If you want to skyrocket your app’s performance and speed, Redis® is one of the never-fail solutions. It is an in-memory key-value store that improves your database queries; thus, it enhances the performance of web applications. Redis finds applications in caching, real-time analytics, session management, etc. It is suitable for high-hit websites or fast back-ends to improve performance rapidly for other applications. It gives great enhancements to performance.

Cantech offers industrial-grade Linux VPS hosting, shared hosting, and reseller hosting solutions. For a Redis® database or cache, we assure you high availability, enhanced security, and smooth performance on our Linux VPS hosting. Our servers are optimally configured for Redis® to enable business or development to scale well.

Why Choose Redis®?

Redis is among the most considered in-memory data stores in the world. Here is why:

  • Lightning-Fast Performance: Redis® keeps the data in RAM and offers much faster data retrieval than traditional databases.
  • Data Persistence: Redis® uses two persistence methods: Append Only File (AOF) and Redis Database File (RDB).
  • High scalability: Redis enables very high scalability with millions of requests processed per second; the most suitable solution for large applications.
  • Rich data structures: It supports strings, lists, sets, sorted sets, hashes, bitmaps, geospatial indexes, and streams.
  • Replication and high availability: Redis® features primary-replica replication with an option for automatic failover and high availability.
  • Simple commands and easy configuration: It is straightforward for a beginner and an expert to get started on since the syntax is intuitive.
    Cantech Networks enhances high-performance VPS hosting which can be dedicated to Redis to secure smooth operation, support web applications, databases, or caching and provide improved SSD storage.

Prerequisites

Before installing Redis®, ensure you have:

  • An Ubuntu 24.04 server
  • A non-root user with sudo privileges
  • A stable internet connection

For seamless Redis® hosting, consider our dedicated Linux Server hosting plans with SSD storage and full root access.

Step 1: Update Your System

It’s always good practice to update your system packages before installing new software. Run the following command:

sudo apt update && sudo apt upgrade -y

This ensures your Ubuntu 24.04 system has the latest security updates and bug fixes.

Step 2: Install Redis® on Ubuntu 24.04

Now, install Redis® using the package manager:

sudo apt install redis-server -y

Once installed, verify the installation by checking the Redis® version:

redis-server --version

You should see an output similar to:

Redis server v=7.0.15

Step 3: Configure Redis® for Security and Performance

By default, Redis is set up to listen on 127.0.0.1. To modify the configuration, you have to edit the Redis configuration file.

sudo nano /etc/redis/redis.conf

Look for the following directives and modify them if needed:

bind 127.0.0.1 ::1
port 6379
daemonize yes

Save and exit the file (CTRL+X → Y → ENTER).
Restart Redis® to apply the changes:

sudo systemctl restart redis

Enable Redis® to start on boot:

sudo systemctl enable redis

Check if Redis® is running:

sudo systemctl status redis

If Redis® is active, you should see the following message:

Active: active (running)

Step 4: Secure Redis® with a Password

Security is a crucial aspect of managing Redis®. To set a password, open the Redis® configuration file:

sudo nano /etc/redis/redis.conf

Find the line starting with # requirepass and change it to:

requirepass your-strong-password

Save and restart Redis®:

sudo systemctl restart redis

Now, authenticate with your password:

redis-cli
AUTH your-strong-password

A successful authentication returns OK.
For secure Redis® hosting, consider Cantech’s dedicated servers with DDoS protection and firewall security.

Step 5: Test Redis®

To confirm that Redis® is functioning correctly, try setting and retrieving a key-value pair:

redis-cli
SET testkey "Hello, Redis!"
GET testkey

If everything is set up correctly, you will see:

"Hello, Redis!"

Step 6: Enable Persistence (Optional but Recommended)

To ensure data isn’t lost on server reboots, enable Redis® persistence. Edit the Redis® configuration file:

sudo nano /etc/redis/redis.conf

Uncomment and set:

save 900 1
save 300 10
save 60 10000

Restart Redis®:

sudo systemctl restart redis
