InfluxDB is a time series database designed to handle high write and query loads. It is optimized for time-stamped data, making it ideal for monitoring, analytics, and IoT applications. InfluxDB allows users to store and retrieve time series data with high efficiency and provides powerful querying capabilities.
When working with InfluxDB, you might encounter the error message: ERR: role not found. This error typically arises when attempting to assign a role to a user or perform operations that require specific role permissions.
When this error occurs, you will see a message indicating that the specified role does not exist. This can prevent you from executing certain commands or accessing specific resources within InfluxDB.
The error ERR: role not found suggests that the role you are trying to reference does not exist in the InfluxDB instance. Roles in InfluxDB are used to define permissions and access controls for users. If a role is not found, it means that the role has not been created or there is a typo in the role name.
To resolve the ERR: role not found error, follow these steps:
Ensure that the role name you are using is correct. Double-check for any typos or incorrect capitalization. Role names are case-sensitive.
Use the following command to list all existing roles in your InfluxDB instance:
SHOW ROLES
This command will display a list of all roles. Verify that the role you are trying to use is listed.
If the role does not exist, you need to create it. Use the following command to create a new role:
CREATE ROLE "role_name"
Replace "role_name" with the desired role name.
After creating the role, assign the necessary permissions to it. For example, to grant read access to a database, use:
GRANT READ ON "database_name" TO "role_name"
Replace "database_name" and "role_name" with the appropriate names.
For more information on managing roles and permissions in InfluxDB, refer to the official InfluxDB Authentication and Authorization Documentation.
