一从两主:多源复制

每台mysql 服务器都需要加

my.cnf要加两个参数才可以在GTID多源复制
master-info-repository=TABLE
relay-log-info-repository=TABLE

server1:只接受下面两种数据库，这两种数据来源不同的通道,系统表不复制

replicate_do_db=db1
replicate_do_db=db2

server1 连到 slave1

mysql> change master to master_host='10.24.220.70',master_user='repl',master_password='123',master_port=3306,master_auto_position=1 for channel 'slave1';

server1 连到 slave2 

mysql> change master to master_host='10.169.214.33',master_user='repl',master_password='123',master_port=3306,master_auto_position=1 for channel 'slave2';

server1:

mysql> start slave;    //两个通道一起起动了
Query OK, 0 rows affected (0.02 sec)

mysql> show processlist;
