I am currently trying to setup an 3 servers, 1 for nginx and 2 for php-fpm. the nginx server also have php-fpm since i tested if everything works well.

while using

upstream php-external{ server unix:/var/run/php-fpm/php-fpm.sock; } 

everything works well, but upon changing it to

upstream php-external{ server 192.168.x.x:9000; } 

I am getting an nginx error:

FastCGI sent in stderr: "Primary script unknown" while reading reading response header from upstream, client x.x.x.x, server: x.x.com, request: "GET / HTTP/1.1", upstream: "192.168.x.x:9000", host: "x.x.com"

and on the browser it shows:

File not found

Here is my nginx.conf:

Here is my php-fpm.d/www.conf from external server:

    Why would you ever do that? Commented Feb 18, 2016 at 5:53
  • Just testing, how do i give access? Commented Feb 18, 2016 at 5:54

You have to deploy your code (php files) to your php-fpm servers as well. If you don't use a path translation (can be done here: fastcgi_param SCRIPT_FILENAME ...) it has to be on the same location as on your Nginx server.

For your php-fpm servers: Take care that they are listening on port 9000 on the correct network interface:

netstat -nltp

(p option works only for user root)
