Connecting RDS to an external server for replication issues

0

Hi all, We're going to be moving to AWS soon, and I am wanting to setup replication to an external main server . I have followed this guide: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/MySQL.Procedural.Importing.External.Repl.html

Steps I took: Made a user on the Main server mocking what was in the write-up

I flushed privileges'

I then set the main server on our AWS database CALL mysql.rds_set_external server ('XX.XX.XX.XX', 3528, 'repl_user', 'MYSQL_PASSWORD_Main', 'mysql-bin-changelog.008401', 14545731, 0);

I am presented with the errors below. The MySQL port is not 3528 and not the default 3306 and although I set it differently it seems its trying to connect to that port still. Just a note we have this server replicating to another dedicated server as well so replication is working on the machine.

Any other things someone could suggest please?

Have you considered AWS Database Migration Service (AWS DMS) which helps you migrate databases to AWS quickly and securely. The source database remains fully operational during the migration, minimizing downtime to applications that rely on the database. At a high level

  • Create a replication instance
  • Create target and source endpoints
  • Refresh the source endpoint schemas
  • Create a migration task
  • Monitor your migration task
