Nginx and Wordpress permalink with .php extension - php

Question

My client's website use Wordpress. The permalink is set to /%postname%.php. See there is .php. So an URL would be look like http://www.example.com/article-url.php.
I am using Nginx and PHP-FPM. That permalink setting did not work as I got File not found error.
Here is my Nginx server block
server {
listen 80;
root /var/www/html/example.com;
index index.php index.html index.htm;
error_log /var/log/nginx/example.com.error.log;
server_name example.com www.example.com;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_read_timeout 300;
}
location ~ /\.ht {
deny all;
}
}
Here is the error log says FastCGI sent in stderr: "Primary script unknown" while reading re sponse header from upstream ...
How to correct this?

Answer 1

I've found the solution here.. So what I need to do is to add try_files $uri $uri/ /index.php?$args; under php location
My server block now:
server {
listen 80;
root /var/www/html/example.com;
index index.php index.html index.htm;
error_log /var/log/nginx/example.com.error.log;
server_name example.com www.example.com;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
try_files $uri $uri/ /index.php?$args;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
fastcgi_read_timeout 300;
}
location ~ /\.ht {
deny all;
}
}
