PHP Laravel 无法连接到云端 sql 上谷歌可以 appengine

Question

I am trying to connect my laravel application to MySQL instance on Cloud SQL. I get the error: SQLSTATE[HY000] [2002] No such file or directory

I am following this tutorial https://cloud.google.com/community/tutorials/run-laravel-on-appengine-flexible .

I have the following app.yaml

runtime: php
env: flex

runtime_config:
  document_root: public

env_variables:
  ## Put production environment variables here.
  APP_NAME: MyApp
  APP_ENV: dev
  APP_DEBUG: true
  APP_KEY: base64:AEoXa4s+7hRiWuFnFcR+Xm/he891r1wpM3tGfkH7lqQ=
  APP_STORAGE: /tmp
  VIEW_COMPILED_PATH: /tmp
  SESSION_DRIVER: database
  CACHE_DRIVER: database
  MAPS_GOOGLE_KEY: <SOME_KEY>
  ## Database Configurations
  DB_CONNECTION: mysql
  DB_PORT: 3306
  DB_DATABASE: <NAME>
  DB_USERNAME: root
  DB_PASSWORD: <PASSWORD>
  DB_SOCKET: '/cloudsql/<CONNECTION_NAME>'
  LOG_CHANNEL: stackdriver

beta_settings:
  cloud_sql_instances: sourcing-279920:<CONNECTION_NAME>=tcp:3306

automatic_scaling:
  min_num_instances: 1
  max_num_instances: 7

Where Also, I enabled the SQL Admin API.

}

PS: I am able to connect through the proxy.

Thanks for your help.

Answer 1

First I think that cloud_sql_instances: in beta_settings should be in quotation marks.

If this is not solve the problem, you can try to check this Github issue which is linking to another issue that seems to contain resolution.

I found something like that here on SO as well.

I hope it will help to solve it!
