Magento2: Setup does not even start

[luca-vercelli]

Trying to install Magento-CE-2.0-2016-01-28-02-26-45 on nginx.
The setup does not even start.
When I browse to the homepage, I see the Magento favicon, I see the browser move to /setup/ folder, and then I see a blank page. Some errors appears in log file:

(...) open() "/home/myname/mypath/setup/index.php/navigation" failed (20: not a directory) (...) request: GET /setup/index.php/navigation HTTP/1.1

Similar issue with apache

What OS? Also have you checked file permissions?
You can try setting developer mode to see more detailed errors.

[luca-vercelli]

OS is Linux Ubuntu Server. File permissions look ok, apache user can read and write every file in the docroot, even hidden ones.
I was not able to set up developer mode. If I run

./magento deploy:mode:show

or such, I get an error:

There are no commands defined in the "deploy:mode" namespace.

php version is 5.5.9

Sorry I should have been cleared, before installation, to turn developer mode on, uncomment line 5 on .htaccess and restart server. Also, check contents of var/log and apache logs too

Turned on. I still see a blank page, and no var/log file. In ngninx logs, now I see a different error:
FastCGI sent in stderr: Access to the script /home/myname/mypath/setup/index.php/navigation have been denied (see security.limit_extensions)

[luca-vercelli]

So, I think this is not an issue of Magento but a configuration problem of php5-fpm (fastcgi). The rewrite engine is not working and I cannot set it up.

[luca-vercelli]

I have solved by myself, with a small hacking into nginx.conf.sample. I had to add a rewrite rule to convert "index.php/smthg" into "index.php?smthg":

location ~ ^/setup/index.php {
    rewrite ^/setup/index.php/(.*)$ /setup/index.php?$1 break;
    ...
}

Anyway, I still don't understand how the standard Magento setup can work on nginx.
