<与MySQL服务器的连接丢失& quot;尝试连接到远程MySQL服务器时

我正在使用Zend Framework开发应用程序，并尝试连接到LAN中的远程MySQL数据库.

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

Zend中的数据库连接设置如下:

[一般的]
db.adapter = PDO_MYSQL
db.params.host = 192.168.1.2
db.params.port = 3306 
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 
[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 
[DEVELOPMENT:GENERAL]
db.params.username = root
db.params.password = **
db.params.dbname   = stellarengine
 
我遇到以下错误:
