在我的主人，我做了：
GRANT REPLICATION SLAVE ON *.* TO 'repluser'@'%' IDENTIFIED BY 'mypassword'; 在我的奴隶身上，我看到：
mysql> show slave status \G; *************************** 1. row *************************** Slave_IO_State: Connecting to master Master_Host: 12.34.56.78 Master_User: repluser Master_Port: 6666 Connect_Retry: 60 Master_Log_File: Read_Master_Log_Pos: 4 Relay_Log_File: mysqld-relay-bin.000002 Relay_Log_Pos: 4 Relay_Master_Log_File: Slave_IO_Running: Connecting Slave_SQL_Running: Yes Replicate_Do_DB: mydb 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: 0 Relay_Log_Space: 107 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: NULL Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 1045 Last_IO_Error: error connecting to master '[email protected]:6666' - retry-time: 60 retries: 86400 Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 0
它只是挂起。 但是，如果我尝试通过mysql -u repluser -h 12.23.45.67 -P 6666 p连接，我可以连接到主机就好了。
我的港口，6666是开放的，允许的。
不知道还有什么要做。
我在http://nerdherd.com/archives/524find了答案
Note the error code 1045, which indicates a credentials problem. Double-check the length of your password; MySQL has a MASTER_PASSWORD maximum length limit of 32 characters. Shorten that puppy up and have another try.
我需要在服务器上为我的奴隶命名，所以我把它叫做servidor ，就像下一个：
GRANT REPLICATION SLAVE ON *.* TO 'servidor'@'%' IDENTIFIED BY 'servidor';
服务器上的下一行是：
MASTER STATUS
我得到了下一个：
+------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000005 | 1232 | pizzeria | | +------------------+----------+--------------+------------------+
所以我需要在客户端作为下一个：
CHANGE MASTER TO MASTER_HOST='172.25.3.44', MASTER_USER='servidor' MASTER_PASSWORD='servidor', MASTER_LOG_FILE='mysql-bin.000005', MASTER_LOG_POS=1232;
