MySQL5.7多源復制的實驗
node1: 192.168.2.171???? master1
node2: 192.168.2.172???? slave
node3: 192.168.2.170???? master2
?
?
node2上執行：
change master to
master_host='192.168.2.171',
master_user='rpl',
master_password='Abcd@1234',
master_port=3306,
master_log_file='mysql-bin.000001',
master_log_pos=4 for channel 'master-1';
?
change master to
master_host='192.168.2.170',
master_user='rpl',
master_password='Abcd@1234',
master_port=3306,
master_log_file='mysql-bin.000001',
master_log_pos=12 for channel 'master-2';
?
?
啟動：
start slave for channel 'master-1';
start slave for channel 'master-2';
?
查看狀態：
show slave status for channel 'master-1'\G
show slave status for channel 'master-2'\G
?
停止：
stop slave for channel 'master-1';
stop slave for channel 'master-2';
?
清空同步信息和日志：
reset slave for channel 'master-1';
reset slave for channel 'master-2';
?
刷下relaylog：
flush relay logs for channel 'master-1';
flush relay logs for channel 'master-2';
