I have added two line in: "/etc/php5/fpm/php-fpm.conf". There are:

chroot = /home/user/www/public_html

chdir = /

In the server section of my: /etc/nginx/sites-available/default:

root /home/user/www/public_html/site.com;

location ~ .php$ {

    try_files $uri =404;

    fastcgi_pass unix:/var/run/php5-fpm.sock;

    fastcgi_index index.php;

    include fastcgi_params;

    fastcgi_param  DOCUMENT_ROOT    /site.com;

    fastcgi_param  SCRIPT_FILENAME  /site.com$fastcgi_script_name;

    fastcgi_param  PATH_TRANSLATED  /site.com$fastcgi_script_name;

}

nginx (or fpm I think) tells me: "File not found". Ok I do following:

root /home/user/www/public_html/site.com;

location ~ .php$ {

    try_files $uri =404;

    fastcgi_pass unix:/var/run/php5-fpm.sock;

    fastcgi_index index.php;

    include fastcgi_params;

    fastcgi_param  DOCUMENT_ROOT    /home/user/www/public_html/site.com;

    fastcgi_param  SCRIPT_FILENAME  /home/user/www/public_html/site.com$fastcgi_script_name;

    fastcgi_param  PATH_TRANSLATED  /home/user/www/public_html/site.com$fastcgi_script_name;

}

And now all works fine. What's wrong with the chroot in fpm? Yeah and by the way - why do it works now when I have set a chroot value! I thought it maybe uses another config but:

# ps aux | grep php

root      4696  0.0  1.3 221452 13768 ?        Ss   16:52   0:00 php-fpm: master process (/etc/php5/fpm/php-fpm.conf)  

What's my fault? How to find out what's the root of a problem here? It looks like the chroot here doesn't chroot my system :)
Do I need to do something else to get chroot working?

Also I have:

# cat /var/log/nginx/site.com-errors.com.log

2014/12/02 17:11:20 [error] 5472#0: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: ...., server: site.com, request: "GET /test.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "site.com"

Looks like the chroot doesn't work anymore in php5-fpm. It was working for me for a while before.

So you run a pool in chroot, but your paths are pointing to the directory tree without chroot. You should change the paths in the fastcgi_param options to reflect the actual path inside the chroot, so the chrooted php-fpm gets a proper understanding where to look for the php scripts.

I've solved the problem. I didn't make any changes to my configs. I've just done "aptitute update && aptitude upgrade" and voila - now it works with my configs listed above. So I think that was a bug.
