Comparison of Redis version numbers

Methods to view Redis version numbers include: using the command line tools redis-cli, Redis INFO commands, Redis manager, and environment variables. redis-cli --version is suitable for local and remote instances, while redis-cli info | grep redis_version provides more information, but only for local instances. Redis Manager provides a graphical interface, but requires third-party tools. The environment variable echo $REDIS_VERSION is useful in specific environments such as Docker.

Comparison of Redis version number viewing methods

Preface

Redis version number is critical to managing and maintaining Redis instances and provides information on Redis features and fix-levels. This article will compare several ways to view Redis version numbers and introduce their pros and cons.

Method 1: Use the command line

 <code>redis-cli --version</code>

advantage:

• Suitable for both local and remote Redis instances.
• Easy to use.

shortcoming:

• Redis-cli needs to be installed.

Method 2: Use the Redis INFO command

 <code>redis-cli info | grep redis_version</code>

advantage:

• You can view more information about the Redis server.
• No additional tools are required.

shortcoming:

• Applicable to local Redis instances only.

Method 3: Use Redis Manager (such as RedisInsight)

advantage:

• Provides an intuitive overview of Redis servers.
• Allows easy viewing of version numbers and other information.

shortcoming:

• Rely on third-party tools.
• Pay may be required to access advanced features.

Method 4: Use environment variables

 <code>echo $REDIS_VERSION</code>

advantage:

• Especially useful in container environments such as Docker.

shortcoming:

• You may need to manually set environment variables.
• May not be accessible in all environments.

Summarize

The best way to view Redis version numbers depends on the situation. For local instances, the INFO command is a convenient choice. Redis-cli is a good choice for remote instances or scenarios that require more information. If you prefer a graphical interface, you can use the Redis Manager. Environment variables are suitable for environments where version numbers need to be automatically obtained.
