Redis command: ACL USERS

Redis Command: ACL USERS

Redis is a popular and powerful in-memory data store that offers a wide range of commands for managing and manipulating data. One such command is the ACL USERS command, which allows you to list all the Access Control List (ACL) users in your Redis server.

What is ACL?

Access Control List (ACL) is a security feature in Redis that enables you to control and restrict access to the Redis server and its operations. ACL provides a way to authenticate and authorize users, defining what actions they can perform on the server and the data stored in it.

How to use ACL USERS command?

To list all the ACL users in your Redis server, you can use the following command:

ACL USERS

This command will return a list of all the ACL users along with their associated permissions and other relevant information. The response will include details such as the username, user ID, and the roles assigned to each user.

Example Usage

Let's say you have set up several ACL users in your Redis server with different roles and permissions. To view all the ACL users and their details, simply execute the ACL USERS command:

127.0.0.1:6379> ACL USERS
User 1: username=user1
   commands: all
   keys: all
   passwords: all
   commands categories: all
   max memory: unlimited
   max clients: unlimited
   ... (other user details)
User 2: username=user2
   commands: set, get, del
   keys: test:*
   passwords: no
   commands categories: strings, keys
   max memory: 1gb
   max clients: 10
   ... (other user details)

In the above example, the ACL USERS command lists two ACL users (user1 and user2) along with their assigned roles and permissions. The output provides valuable information about each user's capability to execute commands, access keys, use passwords, and more.

Summary

The ACL USERS command in Redis provides a convenient way to view all the ACL users along with their roles and permissions. It is essential for understanding the access control and security settings in your Redis server.

By leveraging the ACL functionality, you can enhance the security of your Redis server and ensure that only authorized users are allowed to perform specific operations on your data. The ACL USERS command is just one of the many tools available to you for managing ACL users and securing your Redis infrastructure.
