What is the Default Redis Version in Ubuntu and How to Update It?

What version of Redis is pre-installed on your Ubuntu system? How can you update it to the latest version? This article provides clear steps to check and update the default Redis version in your Ubuntu environment.

Checking the Default Redis Version

To check the current version of Redis installed on your Ubuntu system, follow these steps:

1. Open your terminal.

2. Type the following command:

   shellCopy

   1redis-server -v

This command displays the version number of Redis currently running on your system.

Updating Redis to the Latest Version

If you want to update your outdated Redis version to the latest stable release, follow these steps. A common method to update Redis on Ubuntu is by using the APT package manager.

Step 1: Update Package Lists

First, ensure that your package lists are current. Run this command:

1sudo apt update

Step 2: Upgrade Redis Package

Next, upgrade the Redis package to the latest version available in the Ubuntu repositories. Use the following command:

1sudo apt upgrade redis-server

This command updates the Redis package to the latest version available.

Step 3: Restart Redis Server

After upgrading Redis, restart the Redis server to apply the changes. Execute this command:

1sudo systemctl restart redis-server

With the Redis server restarted, the updated version is now in effect.

Additional Options for Updating Redis

While the APT package manager is a convenient way to update Redis, other methods are also available. If you prefer more control or want to install a specific version of Redis, consider compiling it from source.

Compiling Redis from Source

Compiling Redis from source allows you to choose the exact version and provides flexibility in the installation process. To compile Redis from source, follow these steps:

1. Download the desired Redis version from the official Redis website or GitHub repository.
2. Extract the downloaded archive and navigate to the extracted directory.
3. Compile Redis using the make command.
4. Install Redis by running make install.
5. Verify the installation and start the Redis server.

Compiling Redis from source gives you full control over the version and configuration on your Ubuntu system.

Knowing the default Redis version and how to update it is important for maintaining optimal performance and security. Whether you update using the APT package manager or compile from source, keeping Redis up to date ensures you benefit from its latest features and improvements.
