I am in the process of migrating an on prem mysql database to amazon aurora and used the official AWS documentation. Per the Docs these are the steps that i have followed so far:-
- Set up Percona Xtrabackup.
- Took a backup and moved the data to S3.
- Went to RDS Dashboard and restored the database from S3.
- The Database is up and running successfully.
Now i am in the process of setting up binlog replication where my Aurora instance will be the replica while my on prem mysql is the master. To set up replication, i followed the steps as laid down in the official docs:-
On my master, created a user 'replica-aurora' and provided the necessary permissions using
GRANT REPLICATION SLAVE ON *.* TO 'replica-aurora'@'%' IDENTIFIED BY 'my-secret-password';Ran Show master status on my master which in on prem.
File: mysql-bin.004762 Position: 68093017 Binlog_Do_DB: Binlog_Ignore_DB: Executed_Gtid_Set: 1 row in set (0.00 sec)Connected to my aurora instance and ran the following command :-
CALL mysql.rds_set_external_master ('Ip-of-master', 3306, 'replica-aurora', 'password', 'mysql-bin.004762', 68093017, 0);Ran
CALL mysql.rds_start_replication;When i check the
show slave Status\G. I keep running into the following error message :-Slave_IO_State: Waiting for master to send event Master_Host: Master-IP Master_User: replica-aurora Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.004762 Read_Master_Log_Pos: 71341857 Relay_Log_File: relaylog.000002 Relay_Log_Pos: 195715 Relay_Master_Log_File: mysql-bin.004762 Slave_IO_Running: Yes Slave_SQL_Running: No Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: mysql.rds_replication_status,mysql.rds_monitor,mysql.rds_sysinfo,mysql.rds_configuration,mysql.rds_history Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1032 Last_Error: Could not execute Delete_rows event on table db.feed; Can't find record in 'feed', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.004762, end_log_pos 68293560 Skip_Counter: 0 Exec_Master_Log_Pos: 68288412 Relay_Log_Space: 3249360 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: NULL Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 1032 Last_SQL_Error: Could not execute Delete_rows event on table db.feed; Can't find record in 'feed', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.004762, end_log_pos 68293560
I tried setting sql_slave_skip_counter=1 and ran into this :-
mysql> SET GLOBAL sql_slave_skip_counter = 1; ERROR 1227 (42000): Access denied; you need (at least one of) the SUPER privilege(s) for this operation
I tried skipping the current position using CALL mysql.rds_skip_repl_error; but ran into the following :-
mysql> CALL mysql.rds_skip_repl_error;

which is essentially the same error message as posted above. ERROR 1032.
Any one has ideas on how to fix this problem? I sure would appreciate that.
