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='',master_port=,master_auto_position= for channel 'slave1';
server1 连到 slave2 mysql> change master to master_host='10.169.214.33',master_user='repl',master_password='',master_port=,master_auto_position= for channel 'slave2';
server1:
mysql> start slave; //两个通道一起起动了
