Question

在我的生活中，我不能将我的WordPress Google App Engine部署连接到我拥有的CloudSQL实例。

的app.yaml

application: dark-gateway-XXX
version: wp
runtime: php
api_version: 1

handlers:
- url: /(.*\.(htm|html|css|js))$
static_files: wordpress/\1
upload: wordpress/.*\.(htm|html|css|js)$
application_readable: true

- url: /wp-content/(.*\.(ico|jpg|png|gif))$
static_files: wordpress/wp-content/\1
upload: wordpress/wp-content/.*\.(ico|jpg|png|gif)$
application_readable: true

- url: /(.*\.(ico|jpg|png|gif))$
static_files: wordpress/\1
upload: wordpress/.*\.(ico|jpg|png|gif)$

- url: /wp-admin/(.+)
script: wordpress/wp-admin/\1
secure: always

- url: /wp-admin/
script: wordpress/wp-admin/index.php
secure: always

- url: /wp-login.php
script: wordpress/wp-login.php

我遵循了这些指示。我唯一不同的是重命名我的数据库。 http://googlecloudplatform.github.io/appengine-php-wordpress-starter-project/

任何帮助都将受到赞赏，因为我无法在任何地方找到此信息。

Answer 1

以root用户身份从App Engine连接到Cloud SQL时，不应使用密码，只需使用空字符串：

define('DB_HOST', ':/cloudsql/dark-gateway-XXX:production');
define('DB_USER', 'root');
define('DB_PASSWORD', '');

https://developers.google.com/appengine/docs/php/cloud-sql/#PHP_Connect_to_your_database

您可以在控制台中设置的root密码仅适用于外部连接。

Answer 2

您的文件看起来不错，因此下一步是在运行时验证设置。在wp-config.php中，在define('DB_HOST',...)行之前，添加一行到log执行，例如：

syslog(LOG_INFO, 'setting AppEngine Cloud SQL client parameters');

在预期数据库访问之前和之后，在此处未显示的其他项目文件中添加类似的syslog调用。尽可能包含变量值。查看AppEngine Dashboard的日志部分中的输出。结果应该使您能够逐渐接近实际故障。
