I have 3 master servers, different DBs, I am trying to replicate into a single server. I am having a hard time getting them setup and current. I have Duplicate Entry errors on all 3 Channels. Skipping them manually is painful to say the least. Is there a way to auto sync to the correct position? I was under the impression that this was easy as pie with GTID.
I used:
Dump:
mysqldump --databases profiles --single-transaction --triggers --routines --host=10.10.10.10 --port=3306 --user=user --password=pass > ~/dump.sql
Initialize:
CHANGE MASTER TO MASTER_HOST="10.10.10.10", MASTER_PORT=3306, MASTER_USER="user", MASTER_PASSWORD="pass", MASTER_AUTO_POSITION=1 FOR CHANNEL "channel1";
Master My.cnf:
gtid_mode = ON
enforce_gtid_consistency = true
log_bin = /var/log/mysql/bin_log.index
log_slave_updates = true
server-id = 2061
Slave My.cnf:
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
[mysqld_safe]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
nice = 0
[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
server-id = 10001
explicit_defaults_for_timestamp
gtid_mode=ON
enforce_gtid_consistency=true
log_bin=/var/log/mysql/bin_log.index
log_slave_updates=true
master_info_repository=TABLE
relay_log_info_repository=TABLE
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address = 127.0.0.1
log-error = /var/log/mysql/error.log
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
Am I missing something? Any help is appreciated.
