![]() True multimaster replication would have a Slave with Multiple Masters. After the seconds behind master equal zero, you can delete the RDS-standby DB instance.Whether you have Server configured with WAMP or as a Dedicated DB, the concepts for setting up multimaster replication is identical.īefore I go on, let me clarify the phrase multimaster replication. Check that the replication is synchronizing between RDS-active and MySQL-target: mysql> Show slave status\Gġ8. Log in to MySQL-target, and start the replication: mysql> start slave ġ7. The MASTER_LOG_FILE and MASTER_LOG**_POS** are the values noted in step 5.ġ6. The user name and password are the same user name and password that you created in step 9. The RDS-Endpoint is the endpoint for the RDS-active DB instance. For more information, see How do I resolve problems when connecting to my Amazon RDS DB instance? If you use an external MySQL server, then run telnet to test the connectivity. Note: If you use Amazon Elastic Compute Cloud (Amazon EC2) as an external MySQL instance, then allow connections from the security group or IP address in the security group of the RDS-active DB instance. ![]() Confirm that MySQL-target can connect to RDS-active. Establish a connection to the RDS-active DB instance: mysql> change master to master_host='rds-endpoint',master_user='repl_user', master_password='password', master_log_file='mysql-bin.000001', master_log_pos= 107 ġ5. For example, server_id=2 and replicate-do-db=test.ġ3. Modify the my.cnf file parameters to point to your unique server ID and the name of the database that you want to replicate from the DB instance. Log in to the target DB instance, and then stop the MySQL server.ġ1. Mysql>grant replication slave, replication client on *.* to grants for For more information, see Replication between Amazon Aurora and MySQL, or replication between Aurora and another Aurora DB cluster.ġ0. ![]() Create a new database, and then restore the database using dumpfile to the new external DB instance: $ mysql -h hostname -u username -p dbname create user identified by 'repl_user' After you create the backup, transfer the backup file to the target on-premises server by logging in to MySQL-target.Ĩ. $ mysqldump -h hostname -u username -p dbname > backup_file_name.sqlħ. In this example, the target on-premises server is MySQL-target. Exit the terminal, and use mysqldump (or a similar utility) to create a backup of RDS-standby that will be replicated to the target server. Note: The -log_file is the value of Relay_Master_Log_File, and -log_position is the value of Exec_Master_Log_Pos.Ħ. Record data from the replica, and then note the -log_file and -log_position parameters: mysql> show slave status \G Stop replication on RDS-standby: mysql> call mysql.rds_stop_replication ĥ. Note: The seconds_behind_master must be 0, which means there is no replica lag.Ĥ. Log in to the RDS-standby DB instance, and confirm that the replica is caught up with RDS-active: mysql> show slave status \G In this example, the replica is RDS-standby.ģ. Create a read replica of the DB instance using the same configuration. Note: The minimum backup retention period is one day.Ģ. In this example, the DB instance is RDS-active. Confirm that automated backups are turned on for the DB instance that you want to replicate. If you use GTID-based replication, then see Configuring binary log file position replication with an external source instance. ![]() Then, switch the replication target from the Amazon RDS for MySQL read replica to the on-premises server. To migrate data from Amazon RDS for MySQL to an on-premises database server, first create a read replica on AWS.
