1 FastCGI sent in stderr: "Primary script unknown"

My first time using Nginx, but I am more than familiar with Apache and Linux. I am using an existing project and when ever I am trying to see the index.php I get a 404 File not found.

Here is the access.log entry:

2013/06/19 16:23:23 [error] 2216#0: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.ordercloud.lh"

And here is the sites-available file:

server {
# Listening on port 80 without an IP address is only recommended if you are not running multiple v-hosts
    listen       80;
# Bind to the public IP bound to your domain
#listen 127.0.0.11:80;
# Specify this vhost's domain name
    server_name www.ordercloud.lh;
    root /home/willem/git/console/frontend/www;
    index index.php index.html index.htm;

# Specify log locations for current site
    access_log /var/log/access.log;
    error_log /var/log/error.log warn;

# Typically I create a restrictions.conf file that I then include across all of my vhosts
#include conf.d/restrictions.conf;
# I've included the content of my restrictions.conf in-line for this example

# BEGIN restrictions.conf
# Disable logging for favicon
    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }

# Disable logging for robots.txt
    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }

# Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).
    location ~ /\. {
        deny all;
        access_log off;
        log_not_found off;
    }
# END restrictions.conf

# Typically I create a yiiframework.conf file that I then include across all of my yii vhosts
#include conf.d/yiiframework.conf;
# I've included the content of my yiiframework.conf in-line for this example

# BEGIN yiiframework.conf
# Block access to protected, framework, and nbproject (artifact from Netbeans)
    location ~ /(protected|framework|nbproject) {
        deny all;
        access_log off;
        log_not_found off;
    }

# Block access to theme-folder views directories
    location ~ /themes/\w+/views {
        deny all;
        access_log off;
        log_not_found off;
    }

# Attempt the uri, uri+/, then fall back to yii's index.php with args included
# Note: old examples use IF statements, which nginx considers evil, this approach is more widely supported
    location / {
        try_files $uri $uri/ /index.php?$args;
    }
# END yiiframework.conf

# Tell browser to cache image files for 24 hours, do not log missing images
# I typically keep this after the yii rules, so that there is no conflict with content served by Yii
    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        expires 24h;
        log_not_found off;
    }

# Block for processing PHP files
# Specifically matches URIs ending in .php
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_intercept_errors on;
# Fix for server variables that behave differently under nginx/php-fpm than typically expected
        #fastcgi_split_path_info ^(.+\.php)(/.+)$;
# Include the standard fastcgi_params file included with nginx
        include fastcgi_params;
        #fastcgi_param  PATH_INFO        $fastcgi_path_info;
        #fastcgi_index index.php;
# Override the SCRIPT_FILENAME variable set by fastcgi_params
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
# Pass to upstream PHP-FPM; This must match whatever you name your upstream connection
        fastcgi_pass 127.0.0.1:9000;

    }
}

My /home/willem/git/console is owned by www-data:www-data (my web user running php etc) and I have given it 777 permissions out of frustration...

Can anybody advise?

"Primary script unknown" is caused by SELinux security context.

client get the response

File not found.

nginx error.log has the following error message

*19 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream

so just change security context type of web root folder to httpd_sys_content_t

chcon -R -t httpd_sys_content_t /var/www/show




there are 3 users for nginx/php-fpm config

/etc/nginx/nginx.conf

user nobody nobody;  ### `user-1`, this is the user run nginx woker process
...
include servers/*.conf;

/etc/nginx/servers/www.conf

location ~ \.php$ {
#   fastcgi_pass 127.0.0.1:9000;  # tcp socket
    fastcgi_pass unix:/var/run/php-fpm/fpm-www.sock;  # unix socket
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

/etc/php-fpm.d/www.conf

[www]
user = apache  ### `user-2`, this is the user run php-fpm pool process
user = apache

;listen = 127.0.0.1:9000  # tcp socket
listen = /var/run/php-fpm/fpm-www.sock  # unix socket

listen.onwer = nobody  ### `user-3`, this is the user for unix socket, like /var/run/php-fpm/fpm-www.sock
listen.group = nobody  # for tcp socket, these lines can be commented
listen.mode = 0660

user-1 and user-2 is not necessary to be the same.

for unix socket, user-1 need to be the same as user-3, as nginx fastcgi_pass must have read/write permission on the unix socket.

otherwise nginx will get 502 Bad Gateway, and nginx error.log has the following error message

*36 connect() to unix:/var/run/php-fpm/fpm-www.sock failed (13: Permission denied) while connecting to upstream

In case anyone had the same error: in my case the problem was the missing root directive inside the location block in nginx.conf, as explained in the Arch wiki

That message from the fastcgi server usually means that the SCRIPT_FILENAME that it was given was not found or inaccessible as a file on its filesystem.

Checkout file permissions on /home/willem/git/console/frontend/www/index.php

Is it 644?

And /home/willem/git/console/frontend/www/

Is it 755?

Ok, so 3 things I found after a day of struggling

  1. For some reason I had already something running on port 9000 so I changed to 9001
  2. My default site was intercepting my new one, once again I don't under stand why since it shouldn't, but I just unlinked it
  3. Nginx doesn't automatically do the sym link for sites-available to site-enabled.

Hope this saves someone some trouble!
