mysql gtid 配置

为解决mysql主从延迟问题，采用了mysql5.7的gtid

在/etc/my.cnf中添加

gtid-mode = ON

enforce-gtid-consistency = ON

 

 

-------创建复制帐号，据说不用在从库建，会自己同步过去

mysql> grant replication slave on *.* to 'repl'@'192.168.2.%' identified by '000000';

mysql> flush privileges;

 

 

设置多线程

mysql> show variables like 'slave_parallel_type';

mysql> set global slave_parallel_type='logical_clock';

mysql> show variables like 'slave_parallel_workers';

mysql> set global slave_parallel_workers=5;

 

 

启动同步

mysql> CHANGE MASTER TO MASTER_HOST='192.168.2.210',MASTER_USER='repl',MASTER_PASSWORD='000000',MASTER_AUTO_POSITION=1;

mysql> START SLAVE;
