Nginx configuration for D7 needs documentation

Verified that this bug occurs in the dev version as well.

Upgrading to critical, since, shucks, software not working on ~8% of all setups is pretty critical, no?

After applying the patch listed in the 'duplicate' thread, it removes the error the duplicate thread was created for, but still leaves me unable to install. Here is the new error:

Notice: Undefined index: SCRIPT_NAME in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 389 Notice: Undefined index: SCRIPT_NAME in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 562 Warning: Cannot modify header information - headers already sent by (output started at /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc:389) in /var/www/nginx-default/orangehattech.com/htdocs/includes/install.inc on line 883 Warning: Cannot modify header information - headers already sent by (output started at /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc:389) in /var/www/nginx-default/orangehattech.com/htdocs/includes/install.inc on line 884 

Again, this error is presented on an otherwise blank screen.

What's really odd is that there aren't any errors listed anymore, just notices and warnings, which generally don't stop things from running. Perhaps there's some other problem going on here that I'm not savvy enough to have picked up on.

Ah hah! After puzzling at your response for a good long time, I realized that I can simply add SCRIPT_NAME to the list of variables provided by nginx, and get rid of these errors altogether. This is a new step in making drupal 7 work with nginx, but probably not a bug itself- Just some documentation that needs updating. Perhaps I'll do a blog post about it... Should I ever manage to get my new site up ;)

However, while all the errors have gone away, I'm still left with an utterly blank screen. Going to the url in question /does/ now forward me on to install.php, but install.php appears completely blank.

Ah! It looks like "REMOTE_ADDR", which install.php expects to be filled with something, is, of course, quite empty. What is it expecting here?

In the meantime, I removed the remote_addr requirement, and got the following errors, and, more importantly, a working install prompt. Errors include for the curious.

Notice: Undefined offset: 0 in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 1260 Warning: Cannot modify header information - headers already sent by (output started at /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc:1260) in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 1004 Warning: Cannot modify header information - headers already sent by (output started at /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc:1260) in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 1004 Warning: Cannot modify header information - headers already sent by (output started at /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc:1260) in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 1004 Warning: Cannot modify header information - headers already sent by (output started at /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc:1260) in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 1004 Warning: Cannot modify header information - headers already sent by (output started at /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc:1260) in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 1004 Notice: Undefined index: SERVER_SOFTWARE in /var/www/nginx-default/orangehattech.com/htdocs/includes/common.inc on line 2546 Warning: Cannot modify header information - headers already sent by (output started at /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc:1260) in /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc on line 1004

Looks like it expects SERVER_SOFTWARE. What does it expect THAT to be?

-Dirkson

After locating some really good guesses at REMOTE_ADDR and SERVER_SOFTWARE, and telling nginx to provide them, I was able to get the installer to quit complaining about those two.

Now, it has the following two errors. The first is on the normal page:

Fatal error: Class 'MergeQuery' not found in /var/www/nginx-default/orangehattech.com/htdocs/includes/database/database.inc on line 740

The second is on the install page, after getting past the "Fill in all your site/user information" stage.

Fatal error: Class 'DrupalQueue' not found in /var/www/nginx-default/orangehattech.com/htdocs/modules/update/update.install on line 74

Well, nginx handles these sorts of variables a little differently than apache does. With nginx, I'm talking directly to a php daemon, and I pass it various variables that it uses.

The following gives is the code snippet that tells the php daemon what to do, with D7 specific changes marked as //NEW :

        location ~ \.php {
                fastcgi_pass    127.0.0.1:9040; //IP and port of php-cgi daemon.
                fastcgi_index   index.php;
                fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                fastcgi_param  SCRIPT_NAME      $fastcgi_script_name;                                 //NEW
                fastcgi_param  REMOTE_ADDR      $remote_addr;                                          //NEW
                fastcgi_param  SERVER_SOFTWARE  nginx;                                                     //NEW
                fastcgi_param  QUERY_STRING     $query_string;
                fastcgi_param  REQUEST_METHOD   $request_method;
                fastcgi_param  CONTENT_TYPE     $content_type;
                fastcgi_param  CONTENT_LENGTH   $content_length;
        }

I presume all of this (and more) is provided to php by apache as a matter of course, but nginx provides nothing by default. I'll be sure to make a page where you say as well, documenting what changes I had to apply to nginx to make D7 hale and healthy : )

Unfortunately, my PHP isn't really strong enough for me to feel comfortable writing code others rely on. In case someone reads this who /can/ code the necessary changes, I feel I should mention that not all variables can just be made up by drupal, I think- REMOTE_ADDR, for example, seems to expect the remote IP address, which may have rather nasty effects if you try to fake it. However, SCRIPT_NAME can by synthesized from SCRIPT_FILENAME, and I can't imagine that you couldn't just make up an 'unknown' default value for "SERVER_SOFTWARE".

I'm still a bit lost on the other errors- the 'line 740' appears to be the major one. I found a couple other issues with this error mentioned, but at least one is definitely not related (sqlite issue), so I'm not sure if it's a duplicate or not.

-Dirkson

Well, I'm still stuck with the 'line 740' problem, without any indication of how to move forward from it. It's no longer directly implicating nginx through variables, but it's also not outputting an error I can make much of an educated guess at.

Basically, you can post your configs, it certainly won't hurt, but I don't know what to look for in specific that could be causing the problem now.

Hey! Attempting yet another reinstall with today's dev version and a 'minimal' install results in success.

Two errors, though.

Notice: Undefined index: SERVER_NAME in minimal_form_install_configure_form_alter() (line 10 of /var/www/nginx-default/orangehattech.com/htdocs/profiles/minimal/minimal.profile).

Easy to resolve by adding the variable to the fcgi lines.

Notice: Undefined offset: 0 in request_uri() (line 1259 of /var/www/nginx-default/orangehattech.com/htdocs/includes/bootstrap.inc).

Occurs when looking at the site after the install. This appears to be another "Missing from my D6 nginx config" line; adding REQUEST_URI solves it quite nicely.

Neither errors /appears/ to have any negative effects.
