Redis version requires software installation

Checking Redis Version: Do You Need Extra Software?

No, you don't need to install any additional software to check your Redis version. Redis itself provides commands to retrieve this information. The methods described below leverage the built-in functionality of the Redis server. While graphical tools can be used, they ultimately rely on these underlying commands or connect to the server to execute them.

How Do I Check My Redis Version?

The simplest and most direct way to check your Redis version is using the INFO command within the Redis CLI (Command Line Interface). This command provides a wealth of information about your Redis server, including the version. Here's how you do it:

1. Connect to your Redis server: Open your terminal or command prompt and connect to your Redis instance. The command usually looks like this (adjust the port if necessary):

   redis-cli -h <your_redis_host> -p <your_redis_port>

   Replace <your_redis_host> with the hostname or IP address of your Redis server and <your_redis_port> with the port number (usually 6379). If your Redis server is running locally, you can omit the -h and -p flags.

2. Execute the INFO command: Once connected, type the following command and press Enter:

   INFO server

3. Locate the version: The output will be extensive. Look for a line that begins with redis_version:. The value following the colon is your Redis version number (e.g., redis_version:6.2.5).

What Commands Are Used to View Redis Server Information, Including the Version?

The primary command for viewing Redis server information, including the version, is INFO. However, INFO offers different levels of detail depending on the subcommand you use.

• INFO (without any subcommand): This provides a comprehensive overview of various server aspects, including the version, memory usage, clients connected, and more. It's a great starting point for general server health checks.
• INFO server: This specifically focuses on server-related information, including the Redis version, uptime, and process ID. This is the most efficient command if your sole goal is to retrieve the version.
• Other subcommands: INFO accepts other subcommands like clients, memory, persistence, stats, replication, etc., each providing more detailed information about a specific area of the server's operation.

Is There a Graphical Tool to Check the Redis Version Without Using the Command Line?

Yes, several graphical tools can connect to your Redis server and display its information, including the version. These tools often provide a more user-friendly interface than the command line. Examples include:

• RedisInsight: This is a free, official Redis GUI that provides a visual representation of your data and server information. It can connect to your Redis instance and display the version number within its server information panel.
• Other third-party GUI clients: Numerous other GUI clients are available, offering similar functionality. These tools often require installation and configuration to connect to your Redis server. Keep in mind that even these graphical tools typically use the underlying INFO command (or a similar mechanism) to retrieve the version information from the Redis server. They just provide a more visually appealing presentation of the data.
