About Redis Server
Redis Server is an open-source, in-memory data structure store, used as a database, cache, and message broker. It supports multiple data structures, including strings, hashes, lists, sets, and sorted sets. Redis is also known for its outstanding performance and scalability capabilities. It is frequently used in web applications, real-time analytics, and high-speed transactions.
The Redis Server has a unique feature that makes it outstanding among other databases, which is its ability to persist data to disk. Redis also has a built-in replication feature that allows data to be replicated across different servers, ensuring high availability and data consistency.

Disadvantages of Ubuntu Redis Server
Though Redis Server has many advantages, it also has some disadvantages:
Disadvantages |
Explanation |
|---|---|
In-Memory Storage |
Redis stores data in memory, which can be limiting for large datasets. |
Single Threaded |
Redis is single-threaded, which means it can only execute one command at a time, making it unsuitable for applications with high write loads. |
Security |
Redis does not provide built-in security features, making it vulnerable to security breaches if not correctly configured. |
Complexity |
Redis can be complex to set up and configure for beginners. |
Installing Ubuntu Redis Server
Before you get started, ensure that your Ubuntu system is up-to-date with the latest updates and packages. You can do this by running the following command in your terminal:
$ sudo apt-get update && sudo apt-get upgrade
Step 1: Install Redis Server
To install Redis Server, run the following command in your terminal:
$ sudo apt-get install redis-server
The above command will install Redis Server on your Ubuntu system.
Step 2: Test Redis Server
To test if Redis Server is running correctly, run the following command:
$ redis-cli ping
If Redis Server is running correctly, you will receive a response of “PONG.”
Step 3: Configure Redis Server
By default, Redis Server is configured to listen to all interfaces. To configure Redis to listen to specific interfaces, open the Redis configuration file:
$ sudo nano /etc/redis/redis.conf
Find the line that starts with “bind” and uncomment it by removing the “#” sign. Replace “bind 127.0.0.1” with the IP address of your server:
bind 192.168.0.2
Save and close the file.
Step 4: Restart Redis Server
To restart Redis Server, run the following command:
