假设已经通过xtrabackup，Enterprise backup或 mysqldump等配置好从库。
配置
主库
mysql> show master status; +----------------+----------+--------------+------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +----------------+----------+--------------+------------------+-------------------+ | monitor.000001 | 156 | | | | +----------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
在从库上配置
mysql> CHANGE MASTER TO MASTER_HOST = '127.0.0.1', master_user='root',master_password='dingjia',MASTER_PORT = 13306, MASTER_LOG_FILE = 'monitor.000001', MASTER_LOG_POS = 156; Query OK, 0 rows affected, 2 warnings (0.01 sec) mysql> start slave; Query OK, 0 rows affected (0.00 sec) mysql> show slave status \G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 127.0.0.1 Master_User: root Master_Port: 13306 Connect_Retry: 60 Master_Log_File: monitor.000001 Read_Master_Log_Pos: 156 Relay_Log_File: scutech-relay-bin.000002 Relay_Log_Pos: 322 Relay_Master_Log_File: monitor.000001 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: 156 Relay_Log_Space: 533 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: 123456789 Master_UUID: 41dbce5e-a478-11ea-b751-fa163e0ec694 Master_Info_File: mysql.slave_master_info SQL_Delay: 0 SQL_Remaining_Delay: NULL Slave_SQL_Running_State: Slave has read all relay log; waiting for more updates Master_Retry_Count: 86400 Master_Bind: Last_IO_Error_Timestamp: Last_SQL_Error_Timestamp: Master_SSL_Crl: Master_SSL_Crlpath: Retrieved_Gtid_Set: Executed_Gtid_Set: Auto_Position: 0 Replicate_Rewrite_DB: Channel_Name: Master_TLS_Version: Master_public_key_path: Get_master_public_key: 0 Network_Namespace: 1 row in set (0.00 sec) mysql>
使用GTID自动定位模式
mysql> cHANGE MASTER TO MASTER_HOST = '127.0.0.1', master_user='root',master_password='dingjia',MASTER_PORT = 13306 , MASTER_AUTO_POSITION = 1; Query OK, 0 rows affected, 2 warnings (0.03 sec) mysql> mysql> start slave; Query OK, 0 rows affected (0.00 sec)
