mySQL：從站無法連接到主站進行複制

在我的主人身上，我做了：

GRANT REPLICATION SLAVE ON *.* TO 'repluser'@'%' IDENTIFIED BY 'mypassword';

在我的奴隸身上，我看到：

mysql> show slave status \G;
*************************** 1. row ***************************
              Slave_IO_State: Connecting to master
                 Master_Host: 12.34.56.78

              Last_SQL_Errno: 0
              Last_SQL_Error:

它只是掛起。但是如果我嘗試通過 連接mysql -u repluser -h 12.23.45.67 -P 6666 p，我可以很好地連接到主伺服器。

我的埠 6666 是開放且允許的。

不知道還能做什麼。

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

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 SERVER 中為我的奴隸命名，所以我將其命名為servidor，就像下一個：

GRANT REPLICATION SLAVE ON *.* TO 'servidor'@'%' IDENTIFIED BY 'servidor';  

伺服器上的下一行是：

MASTER STATUS                                                           

我得到了下一個：

+------------------+----------+--------------+------------------+ 
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000005 |     1232 | pizzeria     |                  |
+------------------+----------+--------------+------------------+     

所以我需要呼叫客戶端作為下一個：

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;
