运行时出错 php -S localhost:8080: SQLSTATE[HY000] [2002] No such file or directory. App Engine Standard + MySQL + 入门项目

Question

我正在尝试在谷歌云平台上运行名为“getting-started”的示例应用程序App Engine Standard环境：

Github 来源： https://github.com/GoogleCloudPlatform/php-docs-samples/tree/main/appengine/standard/getting-started

这是我的配置： 应用程序.yaml

runtime: php81

env_variables:
    GOOGLE_STORAGE_BUCKET: as1-kendo-picture-storage
    CLOUDSQL_CONNECTION_NAME: kendo-api-demo:asia-southeast1:bookshelf
    CLOUDSQL_USER: root
    CLOUDSQL_PASSWORD: Hello@2023
    CLOUDSQL_DATABASE_NAME: book-data

当我运行时，该应用程序在生产环境中运行良好：

gcloud app deploy

但是 尝试从 Cloud Shell Editor 在本地主机上运行时出现错误：

php -S localhost:8080

Slim Application Error
The application could not run because of the following error:

我猜本地主机MySQL之间的连接<=>有问题。 但我不知道在哪里以及如何更改配置。 我在本地主机上运行的目的是实时进行 php 调试.

你能帮我解决这个问题吗？

我搜索了很多关于以下内容的结果：

app engine, slim framework, SQLSTATE[HY000] [2002] No such file or directory.

却无法解决问题

非常感谢， 肯

Answer 1

App Engine 为您运行 Cloud SQL 代理并在

/cloudsql/<INSTANCE_CONNECTION_NAME>

处创建一个 Unix 套接字。

要在本地（或在 Cloud Shell 中）模拟相同的连接路径，您需要自己运行 Cloud SQL Auth Proxy：

./cloud-sql-proxy --unix-socket /cloudsql <INSTANCE_CONNECTION_NAME>

有关详细信息，请参阅文档。
