mysql> CHANGE MASTER TO MASTER_HOST='masterdb.example.com', MASTER_USER='repluser', MASTER_PASSWORD='replpassword', MASTER_AUTO_POSITION=1; mysql>start slave;
八、在从数据库上查看复制状态：
mysql> show slave status\G; *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: masterdb.56xyl.com Master_User: repluser Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000002 Read_Master_Log_Pos: 191 Relay_Log_File: slavedb-relay-bin.000003 Relay_Log_Pos: 401 Relay_Master_Log_File: mysql-bin.000002 Slave_IO_Running: Yes #IO线程已正常运行 Slave_SQL_Running: Yes #SQL线程已正常运行 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: 191 Relay_Log_Space: 1899 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_UUID: 971d7245-c3f8-11e5-8b6b-000c2999e5a5 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 the slave I/O thread to update it Master_Retry_Count: 86400 Master_Bind: Last_IO_Error_Timestamp: Last_SQL_Error_Timestamp: Master_SSL_Crl: Master_SSL_Crlpath: Retrieved_Gtid_Set: 971d7245-c3f8-11e5-8b6b-000c2999e5a5:1-6 Executed_Gtid_Set: 89e78301-c3f4-11e5-8b51-00505624d26a:1-3, 971d7245-c3f8-11e5-8b6b-000c2999e5a5:1-6 Auto_Position: 1 1 row in set (0.00 sec) ERROR: No query specified mysql>
九、测试
在主库上创建数据库：
1 mysql> create database log_statics; 2 Query OK, 1 row affected (0.11 sec) 3 4 mysql> use log_statics; 5 Database changed
到从数据库上查看log_statics是否已经复制过去
1 mysql> show databases; 2 +--------------------+ 3 | Database | 4 +--------------------+ 5 | information_schema | 6 | log_statics | 7 | mysql | 8 | performance_schema | 9 +--------------------+ 10 4 rows in set (0.01 sec) 11 12 mysql>
可以看到log_statics数据库已经存在于从数据库上。
