Everything is the same as our primary configuration, except we are using a different server_id and we are pointing to a specific database we want to replicate with replicate_do_db system variable (this is an optional step without it all databases will be replicated). Do not use this mechanism to create the root superuser, that user gets created by default with the password specified by the MARIADB_ROOT_PASSWORD / MYSQL_ROOT_PASSWORD variable. That service may fork into multiple processes (for example, Apache web server starts multiple worker processes). README.md. Same error. Your email address will not be published. Since the log-basename server variable is configured, the binary logs will be stored in files called my-mariadb-bin. where the prefix -bin is added to the log-basename value, and the extension number is created (and incremented) when the server starts, logs are flushed, or the maximum binary log size is reached (max_binlog_size). That's why database connections for app container can be A container can also be frozen with the pause command.
