MySQL在主从复制的时候经常遇到错误而导致Slave复制中断，这个时候就需要人工干涉，来跳过这个错误，才能使Slave端的复制，得以继续进行；
跳过错误的方法：
MariaDB [(none)]> STOP SLAVE; MariaDB [(none)]> SET GLOBAL SQL_SLAVE_SKIP_COUNTER=1; MariaDB [(none)]> SHOW GLOBAL VARIABLES LIKE ‘SQL_SLAVE_SKIP_COUNTER‘; #跳过一个事务 +------------------------+-------+ | Variable_name | Value | +------------------------+-------+ | sql_slave_skip_counter | 1 | +------------------------+-------+ MariaDB [(none)]> START SLAVE;
例如：
Slave错误发生时的状态:
MariaDB [(none)]> SHOW SLAVE STATUS\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.180.100 Master_User: repluser Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000004 Read_Master_Log_Pos: 658 Relay_Log_File: relay-bin.000002 Relay_Log_Pos: 601 Relay_Master_Log_File: mysql-bin.000001 Slave_IO_Running: Yes Slave_SQL_Running: No Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1008 Last_Error: Error ‘Can‘t drop database ‘test‘; database doesn‘t exist‘ on query. Default database: ‘test‘.

使用上面的方法使MySQL的Slave端复制恢复正常：
MariaDB [(none)]> STOP SLAVE; MariaDB [(none)]> SET GLOBAL SQL_SLAVE_SKIP_COUNTER=1; MariaDB [(none)]> SHOW GLOBAL VARIABLES LIKE ‘SQL_SLAVE_SKIP_COUNTER‘; +------------------------+-------+ | Variable_name | Value | +------------------------+-------+ | sql_slave_skip_counter | 1 | +------------------------+-------+ MariaDB [(none)]> START SLAVE; MariaDB [(none)]> SHOW SLAVE STATUS\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.180.100 Master_User: repluser Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000004 Read_Master_Log_Pos: 658 Relay_Log_File: relay-bin.000006 Relay_Log_Pos: 537 Relay_Master_Log_File: mysql-bin.000004 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 658 Relay_Log_Space: 1526 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 1 Master_SSL_Crl: Master_SSL_Crlpath: Using_Gtid: No Gtid_IO_Pos: Replicate_Do_Domain_Ids: Replicate_Ignore_Domain_Ids: Parallel_Mode: conservative
到此，MySQL的主从复制恢复正常。。。大功告成
