Nginx – Blank PHP pages when using php-fpm and nginx on a Debian VPS

debiannginxPHPphp-fpm

I keep receiving a blank page whenever I try to access a PHP page on my nginx webserver on a Debian VPS. nginx is working fine; I can access any normal HTML page. PHP-FPM is at least running, as I can start/restart it and when I stop it the PHP pages give me a 502 bad gateway error, which is normal.

But whenever FPM is running, any PHP page is blank without any errors. This leads me to believe there is a configuration error in FPM.

Here is my php-fpm.conf: http://pastebin.com/CSUuSzxx

Uhm, okay.

So I had logging and error displaying etc. turned on in php.ini, but the logfile location option was commented out. I uncommented it and changed the value to /var/log/php5.log and then went to check the pages again so it would display a blank page and log something to the file.

Instead, the page loaded fine.

A bit odd but I'll take it. Thanks Michael Hampton for the help.

I think your max_children is too low

<value name="max_children">3</value>

Also you can try switching from TCP port to unix socket for php-fpm:

php-fpm.conf

<value name="listen_address">/tmp/php.sock</value>

nginx.conf

fastcgi_pass unix:/tmp/php.sock;

Elaborated:

Unix sockets are ~20% faster
You don't use time-wait sockets for each connect

My php section looks like this:

        location ~ \.php$ {
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_pass unix:/dev/shm/php-fastcgi.socket;
    }

My listen directive in php-fpm.conf this:

listen = /dev/shm/php-fastcgi.socket

Could you also provide your php-fpm.conf? If the error still exists, please enable logging in fpm and provide fpm logs:

php_admin_value[error_log] = /var/log/fpm-php.www.log
php_admin_flag[log_errors] = on
