mysql主从复制数据延时问题

主从都是从用innodb引擎，发生延时问题严重，把从库引擎修改为myisam引擎，暂时效果还不错。

为彻底解决该问题，参考淘宝丁奇的一些策略，打算采用Transfer方式，还在分析之中：

1. show variables like 'binlog_format';? 查看日志格式 mysql5.6?默认 statement，需要修改主库为row模式

这是从网上搜寻的动态修改方式，也可在配置文件中修改

mysql<span>></span> <span>SET</span> <span>SESSION</span> binlog_format <span>=</span> <span>'STATEMENT'</span>;
mysql<span>></span> <span>SET</span> <span>SESSION</span> binlog_format <span>=</span> <span>'ROW'</span>;
mysql<span>></span> <span>SET</span> <span>SESSION</span> binlog_format <span>=</span> <span>'MIXED'</span>;
mysql<span>></span> <span>SET</span> GLOBAL binlog_format <span>=</span> <span>'STATEMENT'</span>;
mysql<span>></span> <span>SET</span> GLOBAL binlog_format <span>=</span> <span>'ROW'</span>;
mysql<span>></span> <span>SET</span> GLOBAL binlog_format <span>=</span> <span>'MIXED'</span>;
