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(zhí)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(tài):

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';
