Last_IO_Errno: 1062

主键冲突的错误 1062

 

模拟错误：

 

在主库上操作：

create table test100(id int not null,name varchar(20),primary key(id));

insert into test100 (id,name) values(100,'lianggj');

 

在从库上操作：

insert into test100 (id,name) values(200,'guo');

 

 

在主库上操作：

insert into test100 (id,name) values(200,'guo');

解决思路：

以主库的为准，把从库上重复的数据删掉。

 

错误解决：

set sql_log_bin=0;

delete from  xxx;

set sql_log_bin=1;

start slave sql_thread;
