"Lost connection to MySQL server" when trying to connect to remote MySQL server

Question

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.

Solution 1

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.

Solution 2

This might help: MySQL Forum: 'reading initial communication packet', system error: 111

Maybe this is not related with zend framework, you need to test just with a simple mysql_connect() function. Probably the error is with your mysql server or network configuration.
