I am trying to follow the guide on setting up master/slave but I get an error:
the database has master/slave configuration with the definition below in config.ini.php.
The configuration with database_reader which we defined slave server; provided
SQLSTATE[HY000]: General error: 1290 The MariaDB server is running with the --read-only option so it cannot execute this statement. So we ended up using master for both.
Why does database_reader user needs to have write access? Are we doing something wrong here?
