Question

尝试连接到不同服务器中的dababase：

命令行

php symfony configure:database "mysql:host=<IP>;dbname=<db_name>" <username> <password>

databases.yml里

  all:   
    doctrine:     
    class: sfDoctrineDatabase     
      param:       
      dsn: 'mysql:host=<IP>;dbname=<db_name>'
      username: <username>       
      password: <password>

获取错误：

PDO连接错误：SQLSTATE [HY000] [2002]连接尝试失败，因为连接方在一段时间后没有正确响应，或者由于连接主机无法响应而建立连接失败
