ACL SAVE

Introduction and Use Case(s)

ACL SAVE command in Redis is used to persist the current Access Control List (ACL) rules to the aclfile. This command is crucial for ensuring that any changes made to the ACL rules are saved and not lost upon server restarts. Typical scenarios include updating user permissions and needing to make sure these updates are saved.

Syntax

  1. ACL SAVE

Parameter Explanations

The ACL SAVE command does not take any parameters.

Best Practices

  • Always use ACL SAVE after making changes to your ACLs to ensure they are persisted.
  • Regularly back up your aclfile to avoid loss of critical security configurations.

Common Mistakes

  • Forgetting to execute ACL SAVE after modifying ACL rules can result in loss of those changes upon server restart.

FAQs

What happens if I do not use ACL SAVE after modifying ACL rules?

If you do not save the ACL rules after modifications, the changes will not persist after the Redis server is restarted, leading to potential security risks.

Can ACL SAVE fail?

Yes, ACL SAVE can fail if there are issues with writing to the aclfile, such as permission errors or disk space issues. Ensure that Redis has the necessary permissions and sufficient disk space.
