MariaDB Error 1794: Slave Configuration Missing
Description
This error indicates that a MariaDB server intended for replication (either as a master or a slave) has not been properly configured. Specifically, the essential `server-id` parameter is either missing or incorrectly set, preventing the server from initializing its replication capabilities. Additional details regarding the failure can often be found in the MariaDB error log.
Error Message
Slave is not configured or failed to initialize properly. You must at least set --server-id to enable either a master or a slave. Additional error messages can be found in the MariaDB error log
Known Causes
4 known causesMissing `server-id` parameter
The `server-id` parameter, which is crucial for identifying a unique server within a replication topology, has not been defined in the MariaDB configuration file.
`server-id` commented out
The `server-id` setting exists in the configuration file (e.g., `my.cnf` or `my.ini`) but is commented out, preventing the MariaDB server from recognizing and applying it.
Server not restarted
After adding or modifying the `server-id` in the configuration file, the MariaDB server process was not restarted to load the new settings.
