The problem of 1062 Last_SQL_Error: Error ‘Duplicate entry’ occurs when the mysql master and slave libraries are synchronized:
 
Obviously the problem is that the slave library does not work because the duplicate primary key is inserted, the error message is as follows

ERROR:
No query specified
The solution is to execute on the slave:
 
 mysql> slave stop;
 mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
 mysql> slave start;
The above method can solve the problem, and another way to solve the problem is to modify the mysql configuration file so that the synchronization thread from the library ignores this error, the method:
 
Modify the mysql configuration file /etc/my.cnf in
[mysqld] Add a line slave_skip_errors = 1062, save. Restart mysql. The mysql slave can be synchronized normally.
