在Google App Engine上运行Wordpress时出现数据库错误

I'm trying to run Wordpress on my PHP runtime whitelisted Google App Engine application. I created a module named "wordpress" and installed Wordpress 3.6.1 (in Dutch) as per the instructions found in this article. (Update: I tried Wordpress 2.5.1 English, 2.6 Dutch and 2.6.1 Dutch. I got the same error messages with all versions.)

It worked without a problem in my local development environment but not in production on Google App Engine. When I go to http://www.mydomain.com/wordpress/, it redirects to http://www.mydomain.com/wordpress/wp-admin/install.php. In the App Engine logs of the Wordpress module I get these messages ("databasefout" means "database error"):

My database wordpress_db on my Google Cloud SQL instance is still empty (no tables). My MySQL user has the following privileges:

What could be the problem? It seems to me Wordpress is trying to access the table wordpress_db.wp_options before creating it.

Update: if I create the database tables manually on the Google Cloud SQL instance, and then go to http://www.mydomain.com/wordpress/ I get the message:

wordpress error establishing a database connection

    Apparently the Wordpress installation only succeeds if you access it via the URL wordpress-dot-myapp.appspot.com. The installation doesn't succeed if you access it via www.mydomain.com/wordpress. Please note that in my case, Wordpress was installed as a module of an existing Python app.

    I had the same issue, my site worked fine on localhost but on server didn't.

    When i went digging deeper into my code, I found out there is some code missing in CREATE [TEMPORARY] TABLE [IF NOT EXISTS] "tbl_name"

    in wordpress file for creating db, can't remember how it's called

    regards
