Strange rewrite behaviour

Greetings again,

I got this weird problem. I have the following virtual domain
configuration:


server {
listen 80;
server_name 2.socialwhale.com;
access_log
/var/www/cluster-domains/2_socialwhale_com/logs/2.socialwhale.log main;
error_log
/var/www/cluster-domains/2_socialwhale_com/logs/2.socialwhale.err;
index index.html index.htm index.php;
root /var/www/cluster-domains/2_socialwhale_com/htdocs/website;

location ~ .php$ {
root
/var/www/cluster-domains/2_socialwhale_com/htdocs/website;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME
/var/www/cluster-domains/2_socialwhale_com/htdocs/website/$fastcgi_script_name;
include fastcgi_params;
}

     error_page  404              /404.html;
      location = /404.html {
         root   /usr/share/nginx/html;
     }

location /var/www/cluster-domains/2_socialwhale_com/htdocs/website {
auth_basic “Restricted”;
auth_basic_user_file
/var/www/cluster-domains/2_socialwhale_com/htpasswd;
}

}


Now if i add the following just after the error_page definition

location / {
try_files $uri $uri/ index.php?$uri&$args;
}

Nginx says the configuration is ok but php-cgi crashes…

Just so you know i am using those lines to other virtual domains with no
problem.

Any ideas?

Hi there,

a few suggestions first, which are not related to the reported
problem:


server {
listen 80;
server_name 2.socialwhale.com;
access_log
/var/www/cluster-domains/2_socialwhale_com/logs/2.socialwhale.log main;
error_log
/var/www/cluster-domains/2_socialwhale_com/logs/2.socialwhale.err;
index index.html index.htm index.php;
root /var/www/cluster-domains/2_socialwhale_com/htdocs/website;

Setting “root” there is good. If you don’t set it inside a particular
location{} block, that value will be inherited (and available as
$document_root)…

location ~ .php$ {
root
/var/www/cluster-domains/2_socialwhale_com/htdocs/website;

…so you could safely omit that line…

        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME

/var/www/cluster-domains/2_socialwhale_com/htdocs/website/$fastcgi_script_name;

…and shorten that line. And then, in future, if you switch directory,
you’ll have fewer places to update in the config file.

        include        fastcgi_params;

Or, instead, you could “include fastcgi.conf” and omit the
SCRIPT_FILENAME
line altogether.

auth_basic_user_file

/var/www/cluster-domains/2_socialwhale_com/htpasswd;
}

That block probably does not do what you want it to. “location” acts on
urls, not file paths. But it’s also unrelated to the reported problem.

Now if i add the following just after the error_page definition

location / {
try_files $uri $uri/ index.php?$uri&$args;
}

Nginx says the configuration is ok but php-cgi crashes…

I’d probably use “/index.php” instead of “index.php” up there. Depending
on what you mean by “php-cgi crashes”, maybe that will help?

If not, then details of what you see vs what you expect to see will
probably help find the problem.

Good luck with it,

Thank you for your quick reply again Francis.

I followed your instructions and made the following changes


root

/var/www/cluster-domains/2_socialwhale_com/htdocs/website;

Commented the above line since i have already set the root dir


         fastcgi_pass   127.0.0.1:9000;
         fastcgi_index  index.php;

fastcgi_param SCRIPT_FILENAME

/var/www/cluster-domains/2_socialwhale_com/htdocs/website/$fastcgi_script_name;

Commented SCRIPT_FILENAME and added the line below :


         include        fastcgi.conf;

As for the authentication part now , the following works as a charm on a
cacti installation but not in the specified virtualhost
(2.socialwhale.com)

location /var/www/html/cacti {
auth_basic “Restricted”;
auth_basic_user_file /var/www/html/cacti/.htpasswd;
}

As for the rewrite rule i tried your recommendation like below :


location / {
try_files $uri $uri/ /index.php?$uri&$args;
}

but still php-cgi does not respond to any .php and after some minutes i
get 402 gateway error.

You’re welcome.

        fastcgi_pass   127.0.0.1:9000;

Do you have the fastcgi server running on this address? Does that server
generate any logs to report if it exits?


location / {
try_files $uri $uri/ /index.php?$uri&$args;
}

but still php-cgi does not respond to any .php and after some minutes i
get 402 gateway error.

You restart or reload nginx, then you access a particular url, and you
do not get the response you expect? The best I can suggest is “check
the logs”.

If the problem is with the fastcgi server exiting, then you’ll need to
investigate that. But so far, I fail to reproduce your problem.

Good luck with it,
