The InnoDB memcached Plugin and Replication Enabling the InnoDB memcached Binary Log 1. To use the  daemon_memcached  plugin with the MySQL binary log, enable the innodb_api_enable_binlog  configuration option on the source server. This option can only be set at server startup. You must also enable the MySQL binary log on the source server using the  --log- bin  option. You can add these options to the MySQL configuration file, or on the  mysqld  command line. 2. Configure the source and replica server, as described in Section 17.1.2, “Setting Up Binary Log File Position Based Replication” . 3. Use  mysqldump  to create a source data snapshot, and sync the snapshot to the replica server. 4. On the source server, issue  SHOW MASTER STATUS  to obtain the source binary log coordinates. 5. On the replica server, use a  CHANGE REPLICATION SOURCE TO  statement (from MySQL 8.0.23) or  CHANGE MASTER TO  statement (before MySQL 8.0.23) to set up a replica server using the source binary log coordinates. 6. Start the replica. If the error log prints output similar to the following, the replica is ready for replication. This example demonstrates how to test the  InnoDB memcached  replication configuration using the memcached  and telnet to insert, update, and delete data. A MySQL client is used to verify results on the source and replica servers. 3380 Testing the InnoDB memcached Replication Configuration 2013-09-24T13:04:38.639684Z 49 [Note] Replication I/O thread: connected to source ’root@localhost:13000’, replication started in log ’0.000001’ at position 114 mysql>  START SLAVE; Or from MySQL 8.0.22: mysql>  START REPLICA; mysql>  CHANGE MASTER TO MASTER_HOST=’localhost’, MASTER_USER=’root’, MASTER_PASSWORD=’’, MASTER_PORT = 13000, MASTER_LOG_FILE=’0.000001, MASTER_LOG_POS=114; Or from MySQL 8.0.23: mysql>  CHANGE REPLICATION SOURCE TO SOURCE_HOST=’localhost’, SOURCE_USER=’root’, SOURCE_PASSWORD=’’, SOURCE_PORT = 13000, SOURCE_LOG_FILE=’0.000001, SOURCE_LOG_POS=114; source shell>  mysqldump --all-databases --lock-all-tables > dbdump.db replica shell>  mysql < dbdump.db mysql>  SHOW MASTER STATUS; mysqld ... --log-bin -–innodb_api_enable_binlog=1
