mysql主从同步跳过错误的方法：

1、跳过指定数量的事务：mysql>slave stop;

mysql>SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1 #跳过一个事务

mysql>slave start

2、修改mysql的配置文件，通过slave_skip_errors参数来跳所有错误或指定类型的错误vi /etc/my.cnf

[mysqld]

#slave-skip-errors=1062,1053,1146 #跳过指定error no类型的错误

#slave-skip-errors=all #跳过所有错误

例：下面模拟一个错误场景

环境(一个已经配置好的主从复制环境)

master数据库IP：192.168.247.128

slave数据库IP：192.168.247.130

mysql版本：5.6.14

binlog-do-db = mydb

在master上执行以下语句：mysql>use mysql;

mysql>create table t1 (id int);

mysql>use mydb;

mysql>insert into mysql.t1 select 1;

在slave上查看复制状态mysql> show slave status\G

由结果可以看到，Read_Master_Log_Pos: 2341，Exec_Master_Log_Pos: 1919时出错了Last_SQL_Error: Error 'Table 'mysql.t1' doesn't exist' on query.

因为只对mydb记录了binlog,当在mydb库操作其它数据库的表，但该表在slave上又不存在时就出错了。
