Ensure 'master_info_repository' Is Set to 'TABLE'


The master_info_repository setting determines to where a slave logs master status and connection information. The options are FILE or TABLE.

NOTE: This setting is associated with the sync_master_info setting as well.


The password which the client uses is stored in the master info repository. This repository by default is a plaintext file.

The TABLE master info repository is a bit safer, but with filesystem access it's still possible to gain access to the password the slave is using.
