MySQL主從不一樣步,出現1062錯誤解決方案

經過查看從服務器的狀態，能夠看到對應的錯誤信息

mysql> show slave status\G
*************************** 1. row ***************************
               Slave_IO_State: Waiting for master to send event
                  Master_Host: 192.168.77.134
                  Master_User: repl
                  Master_Port: 3306
                Connect_Retry: 60

  Replicate_Wild_Ignore_Table: 
                   Last_Errno: 1062
                   Last_Error: Error 'Duplicate entry 'xxx' for key 'PRIMARY'' on query. Default database:...
                   ...

一、 再次同步一次

mysql> stop slave;
Query OK, 0 rows affected, 1 warning (0.03 sec)

mysql> change master to master_host='192.168.77.134', master_user='repl', master_password='test111', master_log_file='syntest.000001', master_log_pos=13691;
Query OK, 0 rows affected, 2 warnings (0.20 sec)

mysql> start slave;
Query OK, 0 rows affected (0.24 sec)

二、跳過當前這個錯誤，在從庫中執行

mysql> stop slave;
Query OK, 0 rows affected, 1 warning (0.03 sec)
mysql> set global sql_slave_skip_counter=1; -- 1 指跳過一個錯誤
Query OK, 0 rows affected (0.00 sec)
mysql> start slave;
Query OK, 0 rows affected (0.24 sec)

三、忽略該類型的錯誤，更改從庫的配置，[mysqld]下加一行slave_skip_errors = 1062 ,保存重啓mysql(/etc/init.d/mysqld restart)。
