Unexpected exception of type [PDOException][HY000] [2005] Unknown MySQL server host

连接本地数据库正常,连接阿里云虚拟主机上mysql服务器时,mysql方式可以正常连接,mysqli与PDO方式连接时,出现错误

Unexpected exception of type [PDOException] with message [SQLSTATE[HY000] [2005] Unknown MySQL server host 


解决方式:连接时不用添加端口

将 return 'mysql:host='.$this->_config['DB_HOST'].':'.$this->_config['DB_PORT'].';dbname='.$this->_config['DB_NAME'];

修改为:

return 'mysql:host='.$this->_config['DB_HOST'].';dbname='.$this->_config['DB_NAME'];
