magento2: Unable to run Web Setup on nginx

Solved:

Changed nginx.conf.sample /setup location block to:

location /setup {
    root $MAGE_ROOT;
    location ~ ^/setup/index.php {

        ### This fixes the problem:
        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        ################################

        fastcgi_pass   fastcgi_backend;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

    location ~ ^/setup/(?!pub/). {
        deny all;
    }

    location ~ ^/setup/pub/ {
        add_header X-Frame-Options "SAMEORIGIN";
    }
}

The fix for me was to update cgi.fix_pathinfo to 1 inside of my php.ini file.

this thread just shows how many people dont know the difference between the real bug and specific environmental configuration.

Almost ONE YEAR after creating this issue, I’ve decided to try Magento 2 again, and I stuck on the same error, in another totally different machine (Ubuntu 16 instead of 14, brand new setup).

Again, the only fix I’ve found was my own fix. I really don’t understand WHY this shouldn’t be merged, since many people related that it fixed for them.

Imagine many new people that want to try Magento 2, and stuck into this error? Not everyone has the know legend to fix this, or seek on github issues.

The solution provided by @iget-esoares didn’t work for me, maybe because I’m running this on Vagrant/Homestead box, but what really worked for me was this:

Insert this directive after this location ~ ^/setup/index.php { try_files $uri $uri/ /setup/index.php?$query_string;

That fixed the problem for me.

Closing this issue, since it is not magento related.

Thanks from me too @iget-esoares. Wonder why so common problem posted only here. Lost 2 days to found fix for it. @mazhalai we need your attention, it’s a BUG

@mazhalai

Yes, it is an magento related problem!

I have many applications running on this machine, from Laravel to Zend applications, and this problem does not occours.

Magento 2 suggests an default nginx conf file that does not work!

i have this problem with apache server and php5.6; setting

cgi.fix_pathinfo=0 or cgi.fix_pathinfo=1

does not work.

In the chrome debugger network tab, i can see that an ajax request is not returning and executed again and again: Request URL:http://localhost/setup/index.php/session/prolong

it happens in angular.js:7715

Edit: my problem was that i had two repos in the composer.json after migration from 1.9

@deenoize if it was a bug then 95% installations would fail… while it’s only few of them, which tells me that you have to check your php cgi.fix_pathinfo variable. or even check your specific setup…

Trying to follow the error.

When I try to access http://magneto/ it give me this:

NOTE: You cannot install Magento using the Setup Wizard because the Magento setup directory cannot be accessed. 
You can install Magento using either the command line or you must restore access to the following directory: /home/esoares/Code/project-community-edition/setup

Following the stack, I found this method: Magento\Framework\App\Http->redirectToSetup() that check if setupinfo is available.

The method isAvailable is:

public function isAvailable()
    {
        var_dump($this->projectRoot) // This dumps: `/home/esoares/Code/project-community-edition/pub/`

        $setupDir = $this->getDir($this->projectRoot); // If I var_dump this, i get: `/home/esoares/Code/project-community-edition/pub/setup`

        $isSubDir = false !== strpos($setupDir . '/', $this->docRoot . '/');
        return $isSubDir && realpath($setupDir);
    }

Note that this is producing wrong setup directory and root directory!

@iget-esoares I believe this is an nginx/php-fpm issue. Please see this thread for a possible solution: http://stackoverflow.com/questions/23390531/access-denied-403-for-php-files-with-nginx-php-fpm?answertab=active#tab-top

magento 2.2.1, php-fpm 7, nginx. Same problem… Only @iget-esoares’s solution helps.

I found simple solution from here: http://dltr.org/blog/magento/583/magento-2-setup-on-existing-vagrant-environment-using-browser
