3、启动同步进程，然后检查状态
#启动同步进程 mysql> start slave; Query OK, 0 rows affected (0.00 sec) #检查状态 mysql> show slave status \G; *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.1.100 Master_User: slave_user Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000019 Read_Master_Log_Pos: 873059878 Relay_Log_File: 192-relay-bin.000002 Relay_Log_Pos: 7294598 Relay_Master_Log_File: mysql-bin.000019 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: erp.claim_staff Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 873059878 Relay_Log_Space: 7294752 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 1 row in set (0.00 sec) ERROR: No query specified这么多信息中，我们只需要看2项，只要为YES即可，分别是：
Slave_IO_Running: Yes # 去主库读二进制日志，然后保存到从库去 Slave_SQL_Running: Yes # 将中继日志转换成为SQL语句执行4、到这里，主从同步指定的表也完成了。
