“与 MySQL 服务器的连接丢失"尝试连接到远程 MySQL 服务器时 [英] "Lost connection to MySQL server" when trying to connect to remote MySQL server

问题描述

我正在使用 Zend Framework 开发我的应用程序，并尝试连接到局域网中的远程 MySQL 数据库.

Zend 中的数据库连接设置如下:<前>[一般的]db.adapter = PDO_MYSQLdb.params.host = 192.168.1.2db.params.port = 3306

[现场直播:一般]db.params.username = rootdb.params.password = **db.params.dbname = djudd

[开发:一般]db.params.username = rootdb.params.password = **db.params.dbname = 恒星引擎

我收到以下错误:

<块引用><块引用><块引用>

致命错误:未捕获的异常 'PDOException' 带有消息 'SQLSTATE[HY000] [2013] 在'读取初始通信数据包'时失去与 MySQL 服务器的连接，系统错误:/usr/share/php/中的 111'Zend/Db/Adapter/Pdo/Abstract.php:129 堆栈跟踪:#0/usr/share/php/Zend/Db/Adapter/Pdo/Abstract.php(129): PDO->__construct('mysql:host=192....', 'root', 'password', Array) #1/usr/share/php/Zend/Db/Adapter/Pdo/Mysql.php(96): Zend_Db_Adapter_Pdo_Abstract->_connect() #2/usr/share/php/Zend/Db/Adapter/Abstract.php(448): Zend_Db_Adapter_Pdo_Mysql->_connect() #3/usr/share/php/Zend/Db/Adapter/Pdo/Abstract.php(238)): Zend_Db_Adapter_Abstract->query('DESCRIBEbny_c...', Array) #4/usr/share/php/Zend/Db/Adapter/Pdo/Mysql.php(156): Zend_Db_Adapter_Pdo_Abstract->query('DESCRIBE bny_c...') #5/usr/share/php/Zend/Db/Table/Abstract.php(823): Zend_Db_Adapter_Pdo_Mysql->describeTable('bny_core_module...', NULL) #6/usr/share/php/Zend/Db/Table/Abstract.php(866): Zend_Db_Table_Abstract->_setupMetadata() #7/usr/share/php/Zend/Db/Table/Abstract.在/usr/share/php/Zend/Db/Adapter/Pdo/Abstract.php 第 144 行

请帮我解决这个问题.

解决方案

上次我遇到这种类型的错误时，我不得不将我的主机从:127.0.0.1 更改为 'localhost' 然后它工作正常.

I am using Zend Framework to develop my application and I try to connect to a remote MySQL database in my LAN.

The database connection settings in Zend is as follows:

[GENERAL]
db.adapter     = PDO_MYSQL
db.params.host = 192.168.1.2
db.params.port = 3306


[LIVE:GENERAL]
db.params.username = root
db.params.password = **
db.params.dbname   = djudd

[DEVELOPMENT:GENERAL]
db.params.username = root
db.params.password = **
db.params.dbname   = stellarengine

I got the following error:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 111' in /usr/share/php/Zend/Db/Adapter/Pdo/Abstract.php:129 Stack trace: #0 /usr/share/php/Zend/Db/Adapter/Pdo/Abstract.php(129): PDO->__construct('mysql:host=192....', 'root', 'password', Array) #1 /usr/share/php/Zend/Db/Adapter/Pdo/Mysql.php(96): Zend_Db_Adapter_Pdo_Abstract->_connect() #2 /usr/share/php/Zend/Db/Adapter/Abstract.php(448): Zend_Db_Adapter_Pdo_Mysql->_connect() #3 /usr/share/php/Zend/Db/Adapter/Pdo/Abstract.php(238): Zend_Db_Adapter_Abstract->query('DESCRIBEbny_c...', Array) #4 /usr/share/php/Zend/Db/Adapter/Pdo/Mysql.php(156): Zend_Db_Adapter_Pdo_Abstract->query('DESCRIBE bny_c...') #5 /usr/share/php/Zend/Db/Table/Abstract.php(823): Zend_Db_Adapter_Pdo_Mysql->describeTable('bny_core_module...', NULL) #6 /usr/share/php/Zend/Db/Table/Abstract.php(866): Zend_Db_Table_Abstract->_setupMetadata() #7 /usr/share/php/Zend/Db/Table/Abstract. in /usr/share/php/Zend/Db/Adapter/Pdo/Abstract.php on line 144

Please help me to resolve this problem.

解决方案

Last time I had this type of error, I had to change my host from: 127.0.0.1 to 'localhost' and then it worked fine.
