We've a Mariadb primary replica configuration on AWS ec2 instances. Can a 2nd replica be added by using AMI of 1st replica including root+ data ebs volumes? If AMI can be used to launch a new ec2 instance for 2nd replica what are the config's to consider like /etc/hosts, /etc/hostname, /etc/mysql/my.cnf for including this in replication from primary?

Mariadb 10.6 on Ubuntu 20.04.6

  • And "server_id". Commented Sep 19 at 1:23
  • Thanks @RickJames -- yes updated server_id to be unique in replication topology. Another point to share, we took the AMI while Mariadb was running, it did perform crash recovery when used that image to launch a new instance. Haven't found this method being used so not sure if this strategy has any implications that discourages it. Commented Oct 1 at 4:53
  • If AMI is a "Machine Image", then that is probably the best way. Commented Oct 2 at 23:47
