DB 리플리케이션 초기 발생 에러

The slave I/O thread stops because master and slave have equal MySQL server ids; these ids must be different for replication to work (or the --replicate-same-server-id option must be used on slave but this does not always make sense; please check the manual before using it).

서버간 server_id 가 동일해서 발생함

# 각 노드에서 sever_id 확인
node1 mysql> SHOW GLOBAL VARIABLES LIKE 'server_id';
node2 mysql> SHOW GLOBAL VARIABLES LIKE 'server_id';

node를 각각 sever_id 1, server_id 2 이런식으로 중복되지 않아야 함

set global server-id=2;

node 1을 그대로 두고 node 2를 위와 같이 바꿈

각 노드에서 리플리케이션 재시작

stop slave;
start slave;
