小编给大家分享一下mysql中slave_exec_mode如何设置自动跳过同步复制错误，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！ slave_exec_mode设置可以跳过1032(记录没有找到)和1062(主键重复)错误，并记录到错误日志中。 slave_exec_mode和slave_skip_errors作用是一样的，只是slave_exec_mode可以在线动态设置。slave_skip_errors必须添加到配置文件中，重启生效。 备库 mysql> select * from testdb1.student;
