mySQL：从属服务器无法连接到主服务器进行复制

在我的主人身上，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

                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:

                   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

然后它就挂了。但如果我尝试通过 连接mysql -u repluser -h 12.23.45.67 -P 6666 p，我就能顺利连接到主服务器。

我的端口 6666 是开放的并且允许。

不确定还能做什么。

我找到了答案http://nerdherd.com/archives/524

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.

答案2

我需要为 SERVER 中的从属设备起一个名字，因此我将其命名为servidor，如下所示：

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     |                  |
+------------------+----------+--------------+------------------+

因此我需要按照以下方式调用客户端：

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;
