运行配置为使用具有相应实例名称的第二代MYSQL实例的Google Nodejs应用程序时，重复出现ENOENT错误 . 这可以使用cloudproxy在我的localhost上运行，但在计算群集实例中会产生以下错误 . 应用程序引擎部署发生类似的错误 .

error when connecting to db: { Error: connect ENOENT cybers-cafe:us-east1:cybers-cafe

  errno: 'ENOENT',

  fatal: true }

我尝试过使用各种socketPath值：

  • cybers-cafe：us-east1：cybers-cafe，

  • / cloudsql / cybers-cafe：us-east1：cybers-cafe，

  • MYSQL实例的IP地址（带和无端口），

  • 只是3306

它们都在计算群集实例和应用程序引擎部署中产生相同的错误 . 我也无法使用计算群集实例中的mysql客户端直接连接到MYSQL实例 .

我已按照https://cloud.google.com/sql/docs/mysql/connect-app-engine等文档中的设置步骤进行操作，如下所示：

env_variables:
  MYSQL_USER: ******
  MYSQL_PASSWORD: ***********
  MYSQL_DATABASE: cyberscafe
  # This path was printed to the console when you started the proxy, and is of
  # the format: `/[DIR]/[YOUR_PROJECT_ID]:[YOUR_REGION]:[YOUR_INSTANCE_NAME]`
  MYSQL_SOCKET_PATH: cybers-cafe:us-east1:cybers-cafe
beta_settings:
  # The connection name of your instance on its Overview page in the Google
  # Cloud Platform Console, or use `[YOUR_PROJECT_ID]:[YOUR_REGION]:[YOUR_INSTANCE_NAME]`
  cloud_sql_instances: cybers-cafe:us-east1:cybers-cafe
