PHP-FPM: Operation not permitted

Question

When I try to open index.php in browser I see the error:

No input file specified.

In error.log:

2013/11/04 22:40:07 [error] 3435#0: *4 FastCGI sent in stderr: "Unable to open primary script: /var/www/index.php (Operation not permitted)" while reading response header from upstream, client: 10.0.2.2, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost"

Configuration of the server:

• CentOS 6.4
• PHP 5.4.17 (installed from sources)
• Nginx 1.0.15

PHP-FPM works from user nginx.

$ ps aux | grep fpm

Switch on catch_workers_output doesn't help

Answer 1

Problem was in non-existent path of setting session.save_path and not in list of setting open_basedir in php.ini
